Installation and Use of Drill Bits

The drill bit opener is a cutting tool used by general drills or drilling machines to cut out circular holes. The basic principle of the bit is to make the bit cut and rotate, cut the workpiece, and then remove the cuttings from the drilling groove.

 

The commonly used bits are twist drill, flat drill, center drill, deep hole drill and trepanning drill. Although reamer and countersink drill can't drill on solid material, they are also traditionally classified as drills.

 

Installation of drill bit opener: Slowly lift the drill box and put the four legs of the drill box into the four holes of the rotary table of the drill. According to the specification of bit cutting, select the corresponding core plate of bit box. Put the core plate of the lifting bit box into the bit box, and then match the bit groove to be installed with the convex point of the core plate of the bit box. Put the drill bit into the drill box, and the drill bit is stuck in the center of the rotary table. Then screw on the drill bit in turn to connect the nut drill pipe.

 

Disassemble of bit: lift the drill pipe (with drill bit), and connect the drill box with the rotary table. Lift the drill pipe slowly so that the bit groove can correspond to the convex tip of the core plate of the bit box. Clamp the drill bit in the drill bit box and remove the drill pipe and drill bit in turn.

 

The drill bit shall be packed in a special packing box to avoid vibration and collision. When it is used, the drill bit taken out of the packing box shall be installed in the spring collet of the spindle or the tool library of automatic bit replacement. Put it into the box after use.

edible-liquid-salt-purification-solution

 

Advantages :

1.Without adding flocculant

Compared with traditional process, continuous reaction filtration, without flocculation & settlement, without numbers of large intermittent clarification tanks, without organic flocculant inhibitor residues in the edible liquid salt are the most remarkable features.

 

2.Resistant to pollution

It is suitable for all kinds of brine.

Inorganic ceramic membrane has excellent antifouling ability, and adopts efficient "cross flow" filtration mode, and runs under high concentration of pollutants (5~10%). It is completely suitable for raw materials with high sulphuric acid and high magnesium content.

 

3.High filtration accuracy

The pore size of ceramic membrane is less than 50nm.

 

4.Stable &high quality refined brine

The SS value of filtrate brine is less than 0.5ppm which results in reducing the possibility of evaporator scaling .

 

5.Long service life

High quality, high strength inorganic tubular ceramic membrane is not subject to acid, alkali and oxidant which works for 5 years under 1MPa working pressure.

 

6.Small footprint

Due to salt purification process, less equipment, simple process control and operation, installation area and construction area can be greatly reduced compared with other technologies.

The newly built 1 million ton vacuum salt brine refining plant has a total of 2 floors with a size of 9m × 40m.

 

Technology introduction:

Brine from outside battery limit goes into reaction tank by brine pump after heated by steam mixer. Refining agent sodium hypochlorite,sodium carbonate and sodium hydroxide are added into the baffle tank where brine enters reaction tank.

 

After finishing dosing, crude brine is formed in the reaction tank. Sodium hypochlorite oxidizes and decomposes organic matters in the crude brine, and sodium carbonate reacts with calcium ions in the crude brine to form crystal precipitates of calcium carbonate, sodium hydroxide reacts with the magnesium ions in the crude brine to form a colloid precipitate of magnesium hydroxide. The crude brine completes the refining reaction and flows into the middle tank by gravity, and is sent to ceramic membrane filtration unit by feed pump after more than 1.0mm of mechanical impurities inside crude brine are removed by a coarse filter.

 

edible-liquid-salt-purification-technology-introduction

 

The inorganic membrane filtration unit adopts three-stage series "cross-flow filtration" mode. Crude brine pumped by feed pump is sent to the first stage filtering module through circulation pump and then concentrate coming from the first stage filtering module goes into the second filtering module, finally concentrate coming from the second stage filtering module goes into the third filtering module.

 

A small part of concentrated brine is discharged into salt sludge tank according to a certain proportion and concentration where flows out from the third filtering module outlet and the rest returns circulation pump inlet and mixes with crude brine send by a feed pump, which the ratio of solid-liquid of feed brine is got to adjust. The mixed brine flows into circulation pump inlet and starts a new cycle filtration through circulation pump which concentrates solid content is controlled and membrane velocity is also ensured.

 

Purified brine filtered by three-stage filtering modules is collected through permeate outlet of each filtering module and sent to make second brine purification by primary brine pump after mixing with sodium sulfite in the refining tank.

Sheet Metal Fabrication Service

What is Sheet Metal Processing?
 

Sheet metal process or sheet metal fabrication includes: folding, shearing, punching, welding, riveting, splicing and other processes. In general, the process of forming a sheet by hand or mechanical is called sheet metal processing. Sheet metal processing is to cut and bend metal materials into various shapes and their thicknesses can vary significantly. According to the materials, sheet metal fabrication can be divided into several types, including aluminum sheet metal fabrication, stainless steel fabrication and brass fabrication. 

Sheet metal process:

Sheet metal processing drawing design -> Laser processing or (CNC stamping) -> Bending -> Welding Molding -> Electrostatic powder spraying or (liquid paint) -> Packaging and shipping.

1. Drawing design:

In general, the customer provide drawings or samples, then our engineers perform the measurement, design, and development, and form the machining decomposition map and assembly drawing to the production department for processing.

2. Laser processing:

It has a large laser cutting machine, it can be cut by laser cutting  such as carbon steel, stainless steel, etc material. After the workpiece is processed, the section is neat, smooth and beautiful, and the size is accurate. It has advantages for the workpiece with arc. CNC stamping can not replace the processing method.

3. CNC stamping:

With imported turret CNC punching machine, CNC punching is mainly for the thickness of product processing materials, generally suitable for materials below 2.5mm. Sheet metal processing workpieces have more holes or need to open special molds to process the workpiece. CNC punching has a certain cost advantage.

4. Bend:

After the workpiece is cut, if most of them need to be bent and formed, the CNC bending machine not only has a fast speed, but also the workpiece is processed more accurately.

5. Welding molding:

The workpiece needs to be assembled and formed after cutting the material, and the assembly method is various. Some are directly formed by non-welding processes such as screws and riveting. Generally, the mechanical casing is made of welding, and the company adopts argon arc welding, bump welding, carbon dioxide welding, etc., we will polished them after welding, so that the workpiece is relatively firm and beautiful.

6. Electrostatic powder spray:

Electrostatic powder spraying is mainly for carbon steel workpieces. In the process, oil removal and derusting, surface cleaning, phosphating, electrostatic powder spraying and high temperature baking are generally carried out. After processing, the surface of the workpiece is beautiful, it will not rust within a few years, and the cost is low.

Liquid paint: This process differs from electrostatic powder spray. It is mainly used for large workpieces. It is convenient and low-cost to use liquid paint when it cannot be handled. The liquid paint is divided into two steps, and the primer is applied to the paint after the workpiece is processed.

7. Packaging and shipping:

100% inspection before packaging and inspection data.

Advantages of Sheet Metal

Sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, large-scale mass production performance, etc. It has been widely used in the fields of electronics, telecommunications, automotive industry, medical equipment and so on. For example, in computer cases, mobile phones, and MP3s, sheet metal is an essential part.
