What is CNC Machining?
CNC machine offered by cnc machining companies in china is commonly used in manufacturing and industrial production. But exactly what is CNC machining?
CNC (Computer Numerical Control) machining is a kind of subtractive manufacturing process. In CNC manufacturing, the software control system issues commands to make the tool meet the required movements. In this process,various precision tools are used to remove layers of raw materials and make parts or products. Therefore, it can also be called cnc precision machining.
Types of CNC Machining
Three-axis CNC machining
The 3-axis machining is performed by straight lines to the axes X, Y, and Z.
Machining features: the cutting tool orientation remains constant during movement along the entire cutting path.
The 3-axis machining center has the advantages of high precision and high efficiency. It is commonly used to machine general parts, but it is more troublesome when machining complex workpieces, which may cause the workpiece to fail. Therefore, multi-axis simultaneous machining is the first choice when machining more complex workpieces.
Five-axis CNC machining
Five-axis machining is the use of CNC to move parts or cutting tools on five different axes simultaneously, which can process very complex parts.
The remarkable feature of the five-axis linkage CNC machine tool is that it can complete the surface machining, and no special fixture is needed during machining, which greatly reduces the number of clamping and improves the machining accuracy, quality and efficiency. The five-axis machining center has unparalleled advantages in the processing of complex workpieces.
CNC milling
CNC milling machine processing is based on the technical requirements of the shape, accuracy, size and surface roughness of the workpiece to determine the processing technology and processing parameters. Program the machining program into the controller and send the command to the servo. CNC milling machines can process parts with particularly complex contours or difficult to control dimensions, such as mold parts and housing parts. It has the advantages of strong adaptability, high processing precision, stable processing quality and high efficiency.
CNC turning
CNC turning is one of the most used machining methods in CNC machining. During CNC turning, the workpiece makes a rotary motion, and the tool moves in a straight line or a curve. While the tool tip moves relative to the workpiece, a certain workpiece material is removed to form a corresponding workpiece surface.
Applications of CNC Machining
Electronic Products
The full metal casing of 3C products is basically processed by CNC machine tools CNC. CNC has become a must-have for 3C enclosure manufacturers due to its high efficiency, high precision and stable processing quality.
Automobile
CNC machining plays an important role in the automotive industry. It can be said that most automotive parts are processed by CNC machining.
The advantages of CNC machining in automobile manufacturing include multi-axis linkage to obtain the tortuous machining of prototype machining; high precision and good product consistency; high degree of automation, resulting in low labor intensity; CNC also ensures simplicity and high efficiency.

Advantages of CNC Machining
- High degree of automation and high production efficiency. Except for the manual clamping of the blank, all other processing can be done automatically by the CNC machine.
- High production efficiency. CNC machine tools can shorten production preparation time and increase the ratio of machining time. Increase productivity by reducing machining time with optimum cutting parameters and optimal path.
- It has strong adaptability to the processing object. When changing the machining object, Except to changing the tool and solving the blank clamping method, it only needs to be reprogrammed, and no complicated adjustment is required, which shortens the production preparation cycle.
- High processing precision and stable quality. Machining dimensional accuracy is between 0.005 and 0.01 mm, independent of the complexity of the part. Most of the operations are done automatically by the machine, eliminating human error and increasing the consistency of batch part sizes.
- A wide range of optional processing materials. The materials processed by CNC are relatively wide, including plastics and hardware.
