With the development of science and technology, people's requirement for parts processing quality is becoming higher and higher. At the same time, product modification is frequent. In general mechanical processing, single and small batch products account for an increasing proportion. In order to ensure product quality, improve productivity and reduce costs, machine tools are required not only to have good versatility and flexibility, but also to have a high degree of automation in the process of processing. cnc machining technology is a kind of high-efficiency and flexible automatic processing technology developed under this environment, which is controlled by digital information of NC machine tools. It is suitable for high-precision, complex parts and small and medium-sized batch production.

CNC machine tool is an efficient and flexible mechanical-electrical integration equipment which integrates computer technology, modern control technology, sensor detection technology, information processing technology, network communication technology, hydraulic pneumatic technology, optical and mechanical technology, and it is the basis of modern manufacturing technology.

1. Composition of NC Machine Tool and NC Machining Process

CNC machine tools refer to the machine tools that use digital information recorded in the media to control the machine tools through the CNC device, so that it can automatically implement the specified processing process.

1) Composition of CNC Machine Tools

NC machine tools automatically process workpieces according to pre-programmed processing procedures. CNC machine tools are usually composed of machine body, servo system, CNC device and control medium, as shown in Figure 2-61.

Figure 2-61 Composition of CNC Machine Tool

Control medium. Control medium, also known as information carrier, is an intermediate medium which conveys the operation intention of human to CNC machine tools. It contains all the information necessary to process a part. Commonly used control media are perforated tape, magnetic tape, disk and other carriers that can store instruction information. For the short NC processing program, the NC device can be input directly through the keyboard on the NC operation panel.

NC device. CNC device is the center of CNC machine tool. It receives the information from control medium, and converts it into pulse signal to control machine tool action.

Servo system. Servo system is a device which connects the moving parts of machine tool with CNC system, including servo drive mechanism and movable parts of machine tool. It is the executive part of CNC system of machine tool. It transforms the impulse signal from CNC device into the movement of machine tool parts, so that the worktable or tool holder can be positioned accurately or moved strictly according to the expected trajectory, and the parts meeting the requirements of the drawings can be machined.

Machine tool.  Machine tool is the mechanical part of NC machine tool. Besides the general parts such as main drive device, feed drive device, bed, worktable and auxiliary part, there are also special parts, such as tool storehouse, automatic tool changer and rotary worktable.

NC Machine Parts Processing Process

The NC machine tool parts processing process is that the operator first changes it into the content of manufacturing process according to the processing pattern. On the basis of familiarity with the processing technology, the processing program is compiled, and the human will is transformed into the acceptable information of CNC machine tools with the prescribed code and program format. Record information on control media (such as punched tape, tape or disk) to make it an instruction for controlling machine tools. After the input information is processed by the NC device, the command pulse is sent to the servo system of the coordinate axes of the machine tool to drive the corresponding moving parts of the machine tool, and other actions such as speed change, tool change and machine shutdown are controlled to automatically process the workpiece that meets the requirements of the drawings.

Classification of 2 NC Machine Tools

CNC machine tools can be classified according to process use, locus of motion, control mode and so on. This paper only introduces the classification according to process use. CNC machine tools are classified according to their processing characteristics or main processing procedures. They are mainly CNC lathes (including turning centers), CNC milling machines (including milling centers), CNC boring machines, CNC machining centers, CNC grinding machines (including grinding centers), CNC drilling machines (including drilling centers), CNC broaching machines, CNC planer, CNC cutting machine, CNC gear processing machine and CNC EDM machine (including EDM center, etc.). Figure 2-62 shows the appearance of CK50 NC lathe. Its processing range is the same as that of ordinary lathe. It mainly processes rotational parts such as shafts and discs. Figure 2-63 shows the appearance of XJK125 NC milling machine. It is especially suitable for the processing of complex parts. It can complete milling, drilling and boring.

Figure 2-63   XJK125 CNC Milling Machine Appearance Diagram

Machining center (MC) is a kind of NC machine tool for multi-process machining of workpiece. It has a tool library and an automatic tool changer (ATC). After the workpiece is clamped once, under the control of the NC system, the machining center can automatically select and change the cutting tools according to different processes; automatically change the spindle speed, feed rate and the movement track of the tool relative to the workpiece and other auxiliary functions; sequentially complete the multi-process processing on several surfaces of the workpiece. Therefore, it reduces the time of workpiece clamping, measuring and machine adjustment, shortens the time of workpiece storage and handling, improves productivity and machine tool utilization, and it is an important development direction of CNC machine tools. Figure 2-64 shows the layout of JCS-018 machining center. Its shape is similar to that of vertical milling machine. There is a sliding seat 2 on the bed 1, and it moves horizontally (y axis direction). Workbench 3 moves longitudinally on the slide seat (x-axis direction). There are frame pillars 5 at the back of the machine tool. The spindle box 9 makes vertical lifting motion (z axis direction) on the column guide rail. The left and right parts of the column are the NC device 6, the left front part is equipped with the tool storehouse 7 and the automatic tool changing manipulator 8, and the left lower part is equipped with the lubrication device 4. There are 16 cutters in the tool library, which can complete all kinds of hole processing and milling. There are 16 cutters in the tool library, which can complete all kinds of hole processing and milling. The NC operation panel 10 is suspended in front of the operator's right for easy operation. The working state of the machine tool is displayed on the panel. Machining centers are usually divided into horizontal, vertical and universal machining centers according to the spatial position of the spindle during processing.

3 Programming

The so-called programming means that the process, process parameters, tool movement and direction and other auxiliary actions (tool changing, cooling, clamping, etc.) of parts are compiled into tables according to the sequence of movement and the instruction code and program format given by the NC machine tools used. This form is called "parts processing program sheet", or simply "procedure sheet". Then, all the contents of the program sheet are recorded on the control medium (such as perforated tape, tape, etc.), and then transmitted to the NC device to direct the NC machine tool processing. The whole process from the analysis of part drawings to the production of control media for NC machine tools is called programming.

Generally speaking, the steps of NC programming are: process design→numerical calculation→preparation of parts processing program sheet→preparation of control medium or program input→program verification and trial cutting.

1) Process design

On the basis of comprehensive analysis of part drawings, the clamping and positioning method, processing route (such as tool setting point, tool changing point, feed route), tool and cutting parameters (such as feed speed, spindle speed, cutting width and cutting depth) are determined.

2) numerical calculation

According to the part drawing and the determined processing route, the tool trajectory is calculated.

The general NC device has the functions of linear interpolation and circular interpolation. For processing simple parts consisting of arcs and straight lines, only the coordinate values of the intersection or tangent points (base points) of adjacent geometric elements on the contour of the part are calculated, and the starting and ending points of the straight line, the starting and ending points of the arc and the coordinate values of the center of the circle can be obtained. When the shape of parts is complex and the interpolation function of NC devices is inconsistent, more complex calculations are needed.

3) Writing Procedure Sheet for Parts Processing

According to the calculated coordinates of tool path, the determined cutting parameters and auxiliary actions, and the instruction codes and program formats prescribed by the NC system, a part processing program sheet is compiled.

4) Preparing control medium or program input

After the program sheet has been written, the operator or programmer must input the processing information into the NC device. According to the different input and output devices of the NC system, the program can be moved to some control medium first. Commonly used control media are U disk, disk, tape and so on.

Program Checking and Trial Cutting

The program must be checked and tested before it can be used formally. The method of checking is to input the contents of the control medium directly into the NC device to check whether the tool's trajectory is correct or not. On the CNC machine tool with CRT graphics display screen, the program checking and trial cutting can be carried out by simulating the cutting process of the workpiece; otherwise, the pen can replace the knife and coordinate paper can replace the workpiece, so that the machine tool can run and draw the processing trajectory.

These methods can only check whether the tool's motion path is correct or not, and can not check the machining accuracy. Therefore, the trial cutting of parts should also be carried out. If it is found that the accuracy of the parts can not meet the requirements through trial cutting, the program sheet and the control medium should be modified, and the error compensation method should be adopted until the qualified parts are processed.

4. Characteristics and Application of CNC Machine Tools

1) Characteristics of CNC Machine Tools

(1) High processing accuracy and stable processing quality. Because of the high manufacturing accuracy of CNC machine tool and the automatic processing according to the scheduled program, the artificial operation error is avoided, the consistency of the same batch of parts is good, and the product quality is stable.

High productivity. Because many parts can be processed in one clamping process, many intermediate processes (such as marking) are omitted. Generally, only the first piece inspection is needed, which greatly shortens the production preparation time, so the productivity is high.

(3) The high degree of automation reduces the intensity of labor and improves the working conditions. Except for the manual clamping of the blank, the whole processing process is automatically completed by the machine tool, which reduces the labor intensity of the operator and improves the working conditions.

(4)It has strong adaptability and good economic benefit. When the processing object is changed, the NC program can be redesigned without redesigning tools, fixtures and moulds. This greatly shortens the product development cycle and provides a shortcut for the development of new products. At the same time, the processing accuracy is high, the quality is stable, the waste rate is reduced, the production cost is reduced, and the productivity is high, so good economic benefits can be obtained.

(5) It is conducive to the modernization of production management. By using NC machine tools, the processing time of parts can be accurately calculated, and the management of inspection, fixture and semi-finished products can be effectively simplified, which is conducive to the modernization of production management. Because of the use of digital information, it is easy to form an integrated computer aided design and manufacturing system.

However, the cost of CNC machine tools is high, the technology is complex and the maintenance is difficult, which requires higher quality of management and operators.

Application of NC Machine Tool

CNC machine tools are widely used, especially suitable for processing parts with the following characteristics: multi-variety, small batch production parts; parts with complex structure and high precision requirements; parts with frequent modifications. CNC machine tools can save a lot of tooling costs, reduce the overall cost. It is expensive, and it does not allow scrap of key parts; urgent parts with the shortest production cycle are needed.

HASCO is a leading European manufacturing company for moulding services and moulds, and is considered to be the standard maker for European moulds. The company recently developed a Quick-Change Mold System. This enables injection moulding manufacturers to quickly and effectively replace their moulds to reduce the time and cost of resetting their machines.

Use and classification of corner shearing machine  . The shearing machine is mainly used in cutting the straight edge of various sizes of sheet metal and is widely used in cars, planes, steel rolling, tractors, ships, Bridges, electric appliance, instrumentation, boiler, pressure vessel and other industries.

There are many kinds of shearing machine. According to shearing machine function, shearing machine working principle and structure, they can be divided into:

First, the Flat blade shearing machine.

It features superior quality, small deformation but large energy consumption. And the two blades are parallel to each other. It is often used in the hot shearing of the Square bloom and the slab in plants.

Second, inclined blade shearing machine.

The upper and lower blade of the shearing machine form an Angle, and the upper blade inclines 1 ° ~ 6 °. The shearing force of the inclined blade shears is smaller than that of the flat blade shearing machine, so the power of the motor and the weight of the whole machine is smaller. It is commonly seen in the practical application. This kind of shearing machine is divided into guillotine shearing machine and pendulum sheet shearing machine according to the motion of the tool holder. And according to the main drive system, it can be divided into two types: mechanical transmission and hydraulic transmission shearing machine.

Third, Multi-purpose shearing machine:

The sheet bending and shearing machine can complete the cutting and bending process on the same machine, which is convenient and practical. Combined punching and shearing machine can be used for cutting of sheets and proximate matter, most of which occur in the laying-off process.

Forth, Special shearing machine:

Sheet flat line shearing machine is used in sheet coil straightening lines. The high-speed shearing machine is designed to cooperate with fast shear requirements. On the thick sheet shearing line, there is mostly hydraulic high-speed shearing machine. While on the thin sheet line, there is mostly pneumatic guillotine shearing machine. And on the high-speed line, there is flying shear, which can work continuously and brings high production efficiency. Steel structure production line shears are mostly used in Angle steel and H section automatic production line to complete the cutting process. Cold bending molding line shears, such as the cold bending line of automobile longitudinal beam, the production line of the side baffle of the car, the molding line of color steel sheet and other special shearing machines.

If you want to know the types of shearing machine, please contact us. We will give you book of shearing machine safety precautions.

The Zhiyun Crane 3S is the latest iteration of Zhiyun’s flagship line of Crane gimbals, traditionally designed for DSLRs and mirrorless cameras. On first glance, the Crane 3S looks a lot like the Crane 3 LAB, but it definitely holds a few extra tricks up its sleeve.

I’ve been using one for a few weeks now when weather and Scotland’s lockdown rules have allowed and I’m going to go over some of those differences and the advantages the Crane 3S has to offer over the Crane 3 LAB.

There are three different Crane 3S kits available. There is the Crane 3S-E, the Crane 3S and the Crane 3S Pro. We’ll get into the differences a little later, but for clarification, the kit I have is the standard Crane 3S.

FIRST IMPRESSIONS & DIFFERENCES OVER THE CRANE 3 LAB

The case for the Crane 3S is quite similar to that of the Crane 3 LAB. It feels a little more compact, although it’s actually pretty close in size. It feels tough and rugged, built from the same kind of hard foam as many gimbal cases these days. It has a top handle for carrying it and locking clips that keep it shut when it needs to be.

Inside though, the Crane 3S case looks a little more cramped than that of the Crane 3 LAB due to a slightly beefier body, with no empty slots for future expansion and upgrades, which is a little disappointing. This was a great feature of the Crane 3 LAB case, which had dedicated slots for all the extras you could buy separately as well as a spare set of batteries. There is still nowhere to add any kind of shoulder strap. So, if you’re carrying the case, you’re tying up one of your hands.

If you buy the 3S Pro kit, I would assume (hope?) that it comes with a different case containing slots for all the extra bits that come with it. But if you’re buying the 3S and hoping to add extras like the focus motor (which only come with the 3S Pro kit), then you’re going to need something else to store them in.

All that said, the case feels solid and everything is packed well inside. The immediate difference between the 3S and the 3 LAB, for the observant ones amongst you, is that the handle isn’t actually attached to the gimbal. Yes, that’s right, it’s removable, and the gimbal can function just fine without it through a bunch of extra buttons on the gimbal body itself or by using the mobile app.

You can see when you look inside the Crane 3S and Crane 3 LAB cases side by side that the 3S is somewhat beefier than the 3 LAB, with noticeably thicker arms and larger motors. This provides the Crane 3S load capacity of a whopping 6.5kg vs the 4.5kg of the Crane 3 LAB. Interestingly, both gimbals have the same minimum load capacity of a somewhat modest 0.6kg. The gimbal itself, however, weighs almost a kilogram more than the 3 LAB, coming in at 3.2kg vs 2.3kg – which is a significant difference.

Pulling it out of the case, the 3S actually feels even more solid than the 3 LAB did. I think this is partly due to the new locking mechanism on the pitch, roll and yaw axes. In the 3 LAB, the arms could either be unlocked and free to move or “locked”, restraining them to a fairly consistent position, although a little movement was available. With the Crane 3S, these locks now have three modes. There’s unlocked, a locked mode similar to the 3 LAB and a new really locked mode, which tightens the arms down hard so that they don’t move at all – which makes balancing a little easier.

One of the things I immediately noticed about the 3S over the 3 LAB was how many connection points it has. But it wasn’t just the quantity that caught my attention, but the fact that some of them have been upgraded from 1/4-20″ to 3/8-16″. This is great because it means you’ll get a more substantial connection between accessories and support systems, but it is slightly annoying in other ways as some accessories will not be interchangeable between gimbals if you own both the Crane 3S and Crane 3LAB, or other gimbals that only utilise 1/4-20″ threads.

The new mounting plate was also something that I noticed right away. It’s still a Manfrotto PL compatible plate, although they’ve ditched the strange extra adjustable platform of the mounting plate that came with the 3 LAB and they’ve also added threads on the front of the plate to attach rods for your follow focus motors. Having this built right into the tripod plate means it’s much easier to set up your camera and balance it properly with a follow focus unit now than it was before because the camera and focus motor is moving together.

You’ll see above that there’s also a lens support supplied with the mounting plate. Personally, I’ve only needed to use this when playing around with the 300mm, but it can be very handy for larger cameras with big lenses that need a little extra assistance. To help with the increased size of the loads it can carry, the whole mount assembly slides left and right from the tilt arm, too, which means you no longer need offset plates for wide cameras like the Blackmagic Pocket 4K.

As a quick aside, while we’re on the topic of focus motors, the Crane 3S is compatible with the Crane 3 LAB focus motors, and there are Type-C USB sockets for connecting both right next to the mounting plate. So, if you’re upgrading from the 3 LAB to the 3S, bear this in mind.

After charging up the batteries and pulling everything out of the case, things went together well. The SmartSling removable handle, which replaces the fixed handle on the Crane 3 LAB goes in and out easily and utilises a double locking system to ensure a good fit with no accidents.

The camera slides onto the mount smoothly and balancing the camera is just as straightforward as it was on the 3 LAB if not a little easier, thanks to being able to completely lock each arm down tight.

Powering it up presents the same array of shooting modes as the Crane 3 LAB and handling seems very similar, albeit slightly heavier.

Let’s dig into a little more detail now, though.

THE SMARTSLING (AND EASYSLING) HANDLES

The kit that I have is the standard Zhiyun Crane 3S package. This includes the SmartSling handle, which offers similar controls to the built-in handle on the Crane 3 LAB except that unlike that one, this is removable.

A removable handle might seem a little odd at first, especially if you’re only used to using gimbals handheld, but it has a few benefits. First, it means you can break the gimbal down into smaller components for more easily packing into a backpack. But it also means that you have easier mounting options for attaching it to things like vehicles, as the arm isn’t going to be getting in the way, and helps to keep everything as compact as possible.

Attaching the Crane 3S to a vehicle isn’t something I’ve tried yet, although it’s on my list. After Scotland’s lockdown is fully over and it’s safe to travel and be in close proximity to other people, it’s one of the first things I’ll be trying when the chance presents itself, so stay tuned for that.

The Crane 3S-E package comes with just the EasySling handle, which is essentially just a rubber-clad metal cylinder with a 3/8-16″ threaded socket in the bottom, a 3/8-16″ threaded screw on the top. It’s clad in rubber to make it easy to grip and not feel so cold when you’re shooting in chilly weather. You can screw this straight into the gimbal, or attach it via a small offset plate, putting it into a similar position to how the SmartSling would mount. Of course, you don’t get any handle controls or display with the EasySling handle.

Despite not being part of the standard 3S kit, I did receive the EasySling handle, and if you decide to only get the standard kit, I’d definitely recommend buying an EasySling handle separately. It’s available as an optional accessory. Both handles come included with the Crane 3S Pro kit, and having them both will make your life much easier with the Crane 3S, especially if you’re using larger cameras, as you can also mount it underneath the gimbal with the supplied tabletop tripod below that.

Being able to use both the SmartSling and EasySling handles simultaneously in this way and pick the whole rig up and set it back down with two hands definitely makes life easier on your arms and back.

I was originally going to recommend that the EasySling handle would be a good upgrade for existing Crane 3 LAB owners who don’t need the added load capacity and versatility of the Crane 3S, but there’s a bit of a snag. The Crane 3 LAB and its accompanying tabletop tripod use 1/4-20″ threads, not 3/8-16″. Hopefully, Zhiyun will release a similar handle that uses 1/4-20″ for Crane 3 LAB users, as Zhiyun has stressed that the 3S is not a replacement model for the 3 LAB, it’s simply another product line.

The mount on the Crane 3S (left) is 3/8-16″, a beefy upgrade from the 1/4-20″ on the Crane 3 LAB (right), although it means parts aren’t interchangeable.

This also means that all your 1/4-20″ quick releases for the Crane 2 and Crane 3 LAB to take it on and off the mini tripod, your monopod, or whatever else you put it on also won’t fit the Crane 3S. Hopefully, they’ll release a 3/8-16″ version, too. Or at least one with a 3/8-16″ hole in the bottom, a 1/4-20″ thread on top, and a couple of 1/4-20″ to 3/8-16″ adapters.

WEIGHT AND SIZE CAPACITY

While the Zhiyun Crane line of gimbals has traditionally held a lot of weight, they’ve had a one or two issues. Many users haven’t been able to take full advantage of that weight capacity due to size limitations. Usually, it’s because the camera just can’t sit off to the side or forward & backwards enough to balance well or the larger camera systems (like the Blackmagic URSA Mini) physically don’t fit. With the Crane 3S, those problems are solved, with the ability to take some pretty large cinema cameras. Even the Blackmagic URSA Mini.

Knowing in advance that I’d have a Zhiyun Crane 3S was on the way to me, I had hoped to get hold of and actually test it with a Blackmagic URSA Mini but then the lockdown happened, making that pretty much impossible. So, I’ve had to make do with the equipment I have here at my disposal. For me, that primarily means Nikon DSLRs and Panasonic mirrorless. Not the best test subjects for a heavy-duty gimbal like this, but it does allow me to test out at least physically large and awkward setups, even if it’s not putting much of a load strain on the gimbal.

My basic setup for these tests was the Nikon D800 and the Sigma 28-70mm f/2.8 lens. It’s not a particularly outstanding setup when it comes to video quality, but it’s a respectable size and weight and represents what you might get with something like a Pocket 4K or larger video-centric mirrorless camera. So, it serves the purpose.

Initially, I tried it out with just the supplied mini tripod screwed into the bottom. Despite the increased weight, it felt quite similar to using the Crane 3 LAB. The movements were pretty much the same, and the general operation didn’t differ too much despite the extra controls and buttons on the Crane 3S.

The one thing that did stick out, though, was the joystick. You can’t unscrew it and remove it on the Crane 3S like you can with the Crane 3 LAB, which can sometimes lead to accidentally knocking it and moving the orientation of the camera if you’re not careful.

What I really wanted to see, though, was how big and useful this thing was fully extended. The extension is a separate piece, and it’s awesome, but it’s also awkward. It’s not designed to be regularly taken on and taken off. The wires contained within the arm are quite delicate and it is quite easy to risk damaging them if you’re not careful. So, if you’re always using larger camera systems, you’ll want to keep the extension attached all the time. This means you’re probably going to be looking for another case in which to keep the gimbal, as it won’t fit into the supplied one with the extension arm attached.

But, I extended the arm on the head of the gimbal, put the EasySling handle underneath and attached the focus motor. My D800 was otherwise engaged, so I just grabbed a 1.5x crop Nikon D7000 – mostly because this would offer me a field of view at a given focal length similar to Super 35mm. On this camera, I put the Nikon 300mm f/4 AF-S, for a field of view similar to a 450mm lens on full-frame. This is a setup that just should not work on a gimbal, and it’s rare you’ll find people using anything longer than about a 60mm or 70mm full-frame equivalent lens, just because such a long focal length massively magnifies the little micro-jitters from the motors or simply being handheld.

It actually held up surprisingly well. You do need to be quite careful, and tracking a moving subject is extremely difficult because the tiniest movement in pan follow mode can translate into a very big shift going ahead of your subject. But I just wanted to see how well it could even handle such an odd (for shooting video on a gimbal) set up and it was very impressive. It held the shot extremely well. Occasionally I moved a little too quickly and it would be pointing at something completely different to what I intended, but when I wasn’t screwing up, it was certainly giving me usable steady shots, without any of the jitters you’d expect with such an unusual load.

It’s certainly not a practical setup, by any means, and not something I’d ever use in the real world, but it served its testing purpose. If you want to go handheld on a static subject at a distance with such a long lens, then it does sort-of work. Of course, I’d probably recommend a tripod with a fluid head instead for this sort of thing, but curiosity got the better of me and I had to try it.

My loads were typically of the DSLR + 28-70mm f/2.8 variety I mentioned earlier, though and it it performed equally as well as the Crane 3 LAB. Except with the added benefit of being able to put the EasySling handle between the gimbal and the mini tripod, making it much easier to pick it up, set it back down and walk around with it two-handed.

BALANCING AND THE NEW LOCKS ON THE ARMS

As mentioned earlier, the Crane 3S features a 3-way locking system over the 2-way system of the Crane 3 LAB, which had them completely loose or sort-of locked. Now you get loose, sort-of locked and locked solid. This actually makes much more of a difference than I expected it to. For easy transporting in a backpack (which the Crane 3S can do, thanks to the removable handle), being able to fully lock the arms provides a much more secure feeling when it’s bouncing around inside the bag. But it also made balancing easier, too.

Instead of having a locked-ish feeling with the two arms I wasn’t currently balancing, I could lock them down completely. They were absolutely immobilised, which meant that it was much easier to adjust the length of the other arms individually and balance each one in turn without wobbles from the other two. As a result, balancing was easier and possibly a little quicker than it was with the Crane 3 LAB, and when you’ve got a big, unbalanced and unwieldy load on there, it definitely helped.

The locks of the Crane 3 LAB were definitely a step in the right direction from the no-lock-at-all on the Crane 2. The Crane 3S just takes that a step further and it made a big difference to me.

OTHER FEATURES

The Crane 3S comes with the usual assortment, but also has one or two extra tricks up its sleeve. As one would expect, there are places to connect a pair of servo motors to control focus and zoom (or aperture) rings on your lens. These sit directly next to the mounting plate for your camera, so they’re within easy reach. The Crane 3S also works with the same motors as the Crane 3 LAB. So, if you’re upgrading from the 3 LAB to the 3S, you won’t need to buy new motors.

There’s also the port on the other side for connecting the gimbal to your camera, offering some level of remote control for a number of brands and models of camera to different degrees. With some, you can control the focus without a servo motor over the USB connection. With others you can adjust the exposure settings. Some cameras allow you to start and stop recording from a button on the gimbal itself. And some don’t offer you any kind of communication between the camera and gimbal at all.

None of my cameras are compatible with the USB communications on the Crane 3S, but I did use the focus motor from my Crane 3 LAB with it and it behaved flawlessly.

One of the big advantages the Crane 3S has over the Crane 3 LAB is when it comes to power. Yes, both of them are powered internally by a trio of Zhiyun 18650 batteries, but the Crane 3S also allows for external power via the Zhiyun TransMount PowerPlus, which extends the battery life with six more 18650 batteries and plugs into a port on the side of the Crane 3S.

SHOOTING MODES AND HANDLING

As you would expect, the Zhiyun Crane 3S offers the usual array of shooting modes including Pan Follow (PF), Follow (F), Point of View (POF), Vortex (V), Lock (L) and Go. Each of these modes offers different ways of shooting to get different kinds of shots.

Pan Follow (PF) – This mode lets you pan and follow your subject on a horizontal plane, even if you’re tilting the actual gimbal for better handholding.

Follow (F) – This mode pans horizontally as well as tilts up and down to follow your movements.

Point of View (POV) – This offers synchronous 360° movements on all three axes.

Vortex (V) – This offers 360° barrel rotation when the gimbal is “underslung”

Lock (L) – This locks the camera to always point in a specific direction, no matter how you turn or tilt the handle.

Go Mode – This mode lets you capture fast action and movement for things like sports or fancy whip pan transitions

All of these modes performed quite well, although I don’t really need to use the POV or Go modes much for the kinds of things I shoot. Pan Follow, Follow, Vortex and Lock modes work as well as we’ve seen from other gimbals in Zhiyun’s lineup – although Vortex isn’t one I need to use too often.

The controls to switch between modes are available on the SmartSling handle with buttons spread around the LCD and to the side, but you can also switch them on the gimbal itself. This means you have access to change modes with either hand if you need it, or when you’re using the EasySling handle.

After using the Crane 3 LAB for the past year or so, switching to the Crane 3S with the SmartSling handle was a doddle. It operates in a very similar fashion. Using the EasySling handle, though, took a little more getting used to. Not having the controls right there at my fingertips with an easy to read display was a pain. If you’ve never used the 3 LAB or the SmartSling handle, you’d probably take to it more quickly. But for me, that EasySling handle will live underneath the gimbal between it and the mini tripod.

And with that setup, it’s absolutely fantastic. SmartSling handle on the back, EasySling handle underneath (if you go for the standard 3S kit, BUY THE HANDLE!) and it felt easier to handle than the Crane 3 LAB, despite the increased weight. Because I was able to more easily distribute that weight, and because I didn’t struggle as much to lift or set down the gimbal, my arms and wrists survived for much longer.

If you’re using a much heavier system, like the previously mentioned URSA Mini, then you’re not going to have such an easy time. It’s certainly not something you’re going to be carrying around all day without some assistance from something like a Steadicam vest & arm or the Digitalfoto Thanos Pro. But, without the arm & vest, it should still be usable for short bursts.

One of the things I’m particularly looking forward to trying, which I haven’t done yet, is vehicle mounting. It’s something Zhiyun showed off in the launch video, and it’s made easier by the fact that there’s a more substantial 3/8-16″ socket underneath but also a second one on top, allowing for two pretty solid mounting points. And as you can remove the SmartSling handle from the gimbal, it’s not sitting there getting in the way.

When using this setup, obviously you’re not going to be holding it. You’re either going to be communicating via smartphone or Zhiyun’s Image Transmission System. But it’s definitely something I plan to try once the country starts to fully open up and it’s safe to hang out with other people again. And what could be a better view for it than the Scottish wilderness on two wheels?

CONCLUSION

Overall, it’s a really nice upgrade over the Crane 3 LAB if you can deal with the extra weight or really need the increased load capacity. If you already have the Crane 3 LAB and it already offers you exactly what you need, then I’d probably stick with it. If you don’t know whether you need the extra features and load capacity the Crane 3S offers over the Crane 3 LAB you already have, then just stick with what you know. But if you don’t have the Crane 3 LAB yet, and you’ve been thinking about it, it’s definitely worth considering the Crane 3S instead.

PROS

When it comes to the pros, there are quite a few – more than I expected over the Crane 3 LAB.

6.5kg load capacity with stronger motors for big beefy rigs

Extendable arm for increased size capacity for larger camera setups

Same minimum load capacity as the Crane 3 LAB

Lateral movements of the camera plate for wide cameras like the Pocket 4K

External power for longer running time with heavier systems

Removable handle to let it fit in a backpack when travelling

The EasySling Handle as a base between the gimbal and tripod (just get it)

CONS

Weight. In a straight side-by-side with the Crane 3 LAB, assuming you’re using a camera setup that works fine on both, you’re carrying around an extra 900g for no real benefit. When you add the EasySling handle, though, it gets easier and for me, it sort of evened things out.

If you’re using a really heavy rig, then you’re going to need to invest in a vest and arm solution for long term use on set.

If you’re thinking about the Crane 3S-E package which only contains the EasySling handle, then I’d probably suggest going for the Crane 3 LAB instead, if you can find one, unless you’re planning to vehicle mount it or something and control it remotely and really need that extra load capacity. The versatility of the built-in handle on the Crane 3 LAB is well worth the extra, plus you save some weight.

If you’re looking at the standard Crane 3S package, then I’d probably recommend going for this over the Crane 3 LAB if you don’t own one already. If you’re concerned about the extra weight, sure, go for the Crane 3 LAB, but given the benefits of the EasySling handle underneath the gimbal in addition to the SmartSling handle controlling the gimbal, I think I’d still prefer the Crane 3S with buying that extra handle (it’s only an extra $49)

If you’re planning to go the whole hog and get the Crane 3S Pro package, then you likely already know that you need both handles, along with the external power, focus & zoom motors and all the extra bits, so just go for it. But plan for the arm & vest.

With Zhiyun's new gimbal about to launch, should you care? And if so, why?

With modern DSLR and mirrorless bodies being more than capable video cameras, a lot of stills shooters have dipped their toes in to moving image waters. However, there was the barrier that is so familiar to photographers the world over: money. To effectively shoot professional quality footage, there's always equipment you could do with owning, but that racks up in cost. However, typical to all technological advance, things are getting smaller and cheaper.

Zhiyun have already built a good reputation in the gimbal world, and their new Crane M2 looks to be an excellent option with a low entry point — a very low entry point. Coming in at just $269, videographers using mirrorless, small DSLRs, or phone cameras can have a serious gimbal for under $300 without having to take your chances with unproven brands. It is certainly an interesting option.

Do you currently have a gimbal at this price point? Are you looking to buy Zhiyun-Tech's new stabilizer? Share your thoughts in the comments below.

Use of Diisobutyl Carbinol (DIBC)

Diisobutyl ketone (DIBK) is a transparent liquid with a distinct odor and a high boiling point. It is an heavy-end byproduct of producing MIBK. DIBK is used in many applications such as nitrocellulose lacquers, synthetic resins, coatings and stains, paint strippers, leather finishings, adhesives, printing and coating inks, cleaning and degreasing, Flavors and fragrances, solvent and re-crystallization aid for pharmaceuticals, mining, and as a chemical intermediate. DIBK has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. The low density and low surface tension of DIBK enables formulators to develop high-solids coatings with low VOC content and excellent flow and leveling properties. DIBK has excellent viscosity reduction for and reduces surface tension in high solid's coatings. It has a good volume-to-weight advantage over other classes of solvents used in coatings. It is a non-HAP (Hazardous Air Pollutant) solvent

Chemical properties of DIBC

Diisobutyl ketone (DIBK) is a colorless oily liquid with a slight, ether, fermented, fruity and sweet jackfruit or peppermint-like odor. Its boiling point is 169°C and the flash point is 45°C. It is insoluble in water, but soluble in ethanol and oils.

Its natural products are found in Congke wine, grape wine, etc.

Uses of DIBC

It is used as a food spice. It is mainly used to make flavors of jackfruit, banana, orange juice, egg fruit, tropical fruit, rum, and konjac.

This product is mainly used as an organic solvent and can also be used for organic synthesis. It can dissolve cellulose acetate, nitrocellulose, polystyrene, vinyl, wax, varnish, natural resin, and raw rubber. Due to its high boiling point and slow evaporation rate, it can be used as a solvent for nitro spray paints, vinyl resin coatings, and other synthetic resin coatings. It is also an intermediate for certain drugs and insecticides.

It is used as an organic synthesis intermediate.

1. CMC Applications Petroleum and Natural Gas

During the exploring, drilling, and workover of petroleum oil and natural gas, the borehole wall is easy to lose water, cause the change of well diameter and collapse of oil well, so that the project can not be carried out normally, even to give up halfway. Therefore, it requires adjusting the physical indexes of drilling mud according to geological conditions, well total depth, temperature, the thickness of different areas. And CMC is the best product to adjust these physical indexed, with the main effect:

1.1 Mud with CMC can form thin and firm filter cake with low permeability on the borehole wall. Prevent hydration of shale and the spreading of drillings. Reduce the collapse of the good wall.

1.2 Mud with CMC is a kind of high efficient fluid loss agent. With a lower dosage (0.3%-0.5%) can well control the fluid loss level, and won't cause poor influence on other performances of mud, such as too high viscosity or shearing force.

1.3 Mud with CMC is high temperature-resistant. Usually, it can be applied under 140℃ high-temperature environment. If use CMC with high substitution degree and high viscosity can be used under 150℃-170℃ high-temperature environment.

1.4 Mud with CMC is of salt-tolerance. The performances of CMC on salt-resistance are: keep reducing dehydrate under certain salt concentration, retain certain rheology effect, and have little change compared with that under freshwater environment. Can apply in clay free drilling fluid, and mud under the saltwater environment. Some are salt-resistant in drilling fluid with small rheology. Especially the salt-resistance CMC produced by Fortune Biotech, the change ratio of viscosity has increased above 1 under 4$ salt concentration and freshwater. That is, viscosity is almost no change in a high salt environment.

1.5 Mud with CMC can control the rheology of slurry. CMC can cut down the fluid loss level, and enhance viscosity.

2. CMC Effects in Drilling Fluids

2.1 Improve the performance of filtration and mud cake quality. Increase anti-jamming ability.

CMC is a kind of good fluid loss additive. Apply in mud can raise liquid phase viscosity and seepage resistance of filter liquor, so control fluid loss at the lowest level.

The add of CMC can make mud cake compact, firm and smooth. Reduce the situation of logging tool sticking owing to the migration of drilling tools. Reduce resisting moment on rotating aluminum rod. Relief the suction phenomenon in the borehole.

CMC dosage in common mud is 0.2%-0.3%. API fluid loss can reduce greatly.

2.2 Improve the shale carrying effect. Increase the stability of oil slurry.

Owing to good thickening property, so even if bentonite content is lower, it can still retain the desired viscosity of carrying debris and suspending barite as long as adding adequate CMC.

2.3 Resist dispersion of clay. Prevent collapse.

The reduction of the fluid loss function of CMC can slow down the hydration speed of mud shale on the borehole wall. As well as covering function on the borehole rock of CMC long-chain, can strengthen the rock structure. Not easy to collapse and spalling.

2.4 CMC is a kind of mud treatment agent with good compatibleness. CMC is compatible with different treatment agents in different mud series. It can have excellent effects.

3. CMC Applications in Well Cementation Spacer Fluids

The normal construction of cementing for good cementation is an important part to ensure good cementation quality. Spacer fluids with CMC have characteristics of reducing flow resistance and facilitating construction, etc..

4. CMC Applications in Workover Fluids

During the operation of formation testing and workover, serious pollution to oil rock will arise if using hight solid mud. To eliminate the pollution is much harder. If only use clear water or brine as workover fluids, it may cause serious leakage. Even water blocking may form due to the water from filtration on the oil rock. Or result in a partial expansion of the mud in the oil rock, and permeability damages.

Apply CMC for workover fluids can successfully solve the above issues. Can use formulations according to the fluid loss level for low-pressure borehole or high-pressure borehole.

Low pressure layer: light fluid loss: clear water+0.5%-0.7% CMC. Common fluid floss: clear water+1.09%-1.2% CMC. Serious fluid loss: clear water+1.5% CMC.

1. Paper Pulp Additives

Apply CMC into the paper pulp (add before pulping and alums mixing). CMC can disperse fiber, improve uniformity and strength of paper (bursting strength and stiffness). Using CMC with the same beating degree can shorten beating time, conserve energy. Dosage of CMC is 0.2%-0.8% of paper pulp. Can use CMC RM8-1. With the add of CMC, paper tension increases 40%-50%, tearing strength raises 50%, flexibility increased 4-5 times. Meanwhile, paper quality is of smoothness with good ink absorbency and clear printing edge. It's much better to use hard water during production.

2. Surface Sizing Agent

Sound surface strength is required during high-speed printing. When there is a low beating degree or high filling content, usually adopt a surface sizing method to increase the surface strength of paper and paperboard, reduce surface absorption. Through surface sizing, fiber holes of paper are sealed by a layer of sizing film. It can reduce the absorption of moisture in the air, as well as evaporation of moisture in the paper. Prevent paper from rolling up and crushing. Improve the paper absorption of ink and oil. Has the effect of grease-proof, waterproof and oil-resistant.

To avoid paper and paperboard surface lint and powder falling, can use CMC solution with low viscosity and medium viscosity. With medium viscosity, CMC solution can get a layer of compact grease-proof film. Usually, use CMC solution with 1%-2% concentration can get 0.1g/m2--0.5g/m2 sizing. Users can also decide CMC viscosity according to the different base paper. It can mix low and medium viscosity CMC. High purity CMC has a good property of paper film-forming. Instead, Industrial grade CMC with low purity has poor performance on paper film-forming. Dosage of CMC is 1/2-1/3 comparing with that of starch. Especially that modern paper-making factories conduct sizing with the high-speed machine, which can only apply CMC solution with lower viscosity and high purity.

3. Coating Agent

Coating whiteboard paper and chrome paper usually need coating pigment. Use CMC in coating color can improve water retention and rheology effect.
