About CNC machining
CNC (Computerized Numerical Control) machining means computer digital control machining, which refers to the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts to be processed in accordance with the instruction codes and programs specified by the CNC machine tool. The format is written into a processing program list, which is input into the numerical control device through the carrier and sends out control signals to control the machine tool to perform actions, and automatically process the parts.
CNC machining realizes the accuracy and shape of parts in place at one time, and better solves the problem of machining parts with complex contours, high precision, small batches and multiple varieties. It is a flexible and efficient automatic machining method and is often used in scientific research. And sample trial production and small batch production in the product development stage.
The Main Process of CNC Machining
Milling refers to a process in which the workpiece is fixed and the multi-blade tool performs rotary cutting to gradually remove material from the workpiece. It is mainly used for the processing of contours, splines, grooves and various complex plane, curved and shell parts. The size of the milling embryo can reach 2100x1600x800mm, and the positioning tolerance can reach ±0.01mm.
Turning refers to the rotation of the workpiece, and the turning tool moves in a straight line or a curve in the plane to realize the cutting of the workpiece. It is mainly used for cutting the inner and outer cylindrical surfaces, conical surfaces, complex surfaces of revolution and threads of shaft or disc parts. The diameter of the turning body can reach 680mm, the positioning tolerance can reach ±0.005mm, and the surface roughness of mirror turning is about 0.01-0.04µm.
Turn-milling compound refers to the composite motion of milling cutter rotation and workpiece rotation to realize cutting processing of workpiece. The workpiece can be processed in multiple processes in one clamping, which can avoid the loss of accuracy and reference loss caused by secondary clamping. . Mainly used for large-scale, high-precision, more complex parts processing.
Features and Benefits of CNC Machining
CNC machining is suitable for machining parts that are complex, have many procedures, have high requirements, and require various types of common machine tools, many tools and fixtures, and can only be processed after multiple clamping and adjustments. The main objects of processing are box parts, complex curved surfaces, special-shaped parts, discs, sleeves, plate parts and special processing.

Complex manufacturing: CNC machine tools can arrange more complex or difficult processes on ordinary machine tools, and can process continuous, smooth and unique surfaces in one clamping.
Automated manufacturing: The CNC machining program is the instructional file of the machine tool, and the whole process of machining is carried out automatically according to the program instructions.
High-quality manufacturing: CNC machining has high efficiency, high precision, high quality, and strong adaptability to different workpieces.
Stable manufacturing: CNC machining performance is stable and easy to operate.
CNC Machined Materials
A wide range of materials suitable for CNC machining, including stainless steel, aluminum alloy, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, etc.

Surface Treatment Of CNC Machining
Most CNC-processed products require proper surface treatment to increase the hardness and corrosion resistance of the product, thereby increasing the service life of the product and improving the aesthetics of the product appearance. The commonly used surface treatments are as follows:
Chemical method: oxidation, electroplating, painting
Physical method: polishing, wire drawing, sand blasting, shot blasting, grinding
Surface printing: pad printing, silk screen printing, water transfer printing, coating, laser engraving
