Precision parts machining: describe the machining methods and characteristics of CNC precision parts
CNC precision parts processing is an advanced processing skill in today's machinery manufacturing industry. It inputs the NUMERICAL control program of the processing parts to the CNC machine tool, which automatically processes the workpiece after receiving the NUMERICAL control program. Numerical control machining skills can be used to solve the complex small and medium batch and variable processing scheme of hardware parts, and meet the needs of modern production.

CNC machining process involves tool selection, cutting parameters and tool path. CNC machining technology is the core of NC programming. Select processing time less, the smallest tool path of the NUMERICAL control program, to achieve high efficiency and high quality products. CNC processing technology can be divided into rough machining, clear Angle, finishing.

When non-standard parts are roughed, large cutting tools should be selected to quickly cut off a large amount of workpiece allowance in the maximum power of the machine tool, so as to rough fine parts. The principle of knife selection is mainly based on whether the chamfering arc surface of the product is too small to consider, after selecting the tool, the resolution of the knife length. In principle, the tool length should be greater than the processing depth. The tools we use are viewpoint, generally need to clear Angle on the step shaft. We need to clear the corner where the milling back cutter groove.

The advantages of doing this are: first, it is convenient for the grinder to grind the shaft quickly back to the sand wheel, and it will not grind to the end face and affect the length. Second, when assembling, it completely touches the end face, and the end face runout will be smaller. < P > Dongguan Lifei Precision Machinery & Mould Co., LTD., established in December 2015, is a mechanical parts factory engaged in manufacturing and assembly services, supporting the processing of all kinds of fixture and precision machinery parts. Currently, there are several process engineers and technical personnel. The company has production equipment such as high-speed CNC machining centers, CNC lathes, lathes, milling machines, grinding machines, wire cutting. And a number of sophisticated inspection equipment, such as microscope, projector, hardness tester, Swiss height meter, three-dimensional, etc., to meet customer product production and processing and quality inspection needs.
