CNC precision parts processing methods and characteristics

CNC machining is an advanced machining skill in today's machinery manufacturing industry. It inputs the CNC program of the processed part to the CNC machine tool, and the machine tool automatically processes the workpiece after receiving the CNC program. Numerical control processing skills can effectively handle the messy, small-to-medium batch and changeable processing plan of hardware parts, which meets the needs of modern production. The CNC machining process involves tool selection, cutting parameters and tool path. CNC machining technology is the core content of CNC programming. Only by selecting the CNC program with the smallest processing time and the smallest tool path can we obtain high-efficiency and high-quality products. The CNC machining process can be divided into rough machining, corner cleaning and finishing. Larger cutters should be used for rough machining, and a lot of workpiece margins should be quickly removed at the maximum power of the machine tool to roughen precision parts. The principle of tool selection is mainly based on whether the chamfered arc surface of the product is too small. After selecting the tool, the tool length is determined. In principle, the tool length is greater than the machining depth. The knives we use have perspectives, and generally require clear angles on the step shaft. Let's mill an undercut in the place where we need to clean the corner. The advantages of this are: firstly, it is convenient for the grinding shaft of the grinder to return the sand wheel as soon as possible, and the end surface will not be ground to affect the length; secondly, the end surface is completely contacted during assembly, and the end surface runout will be smaller. The purpose of finishing light knife is to satisfy the surface finish of precision parts and achieve high precision effect. Therefore, the light knife finishing should choose the fastest speed possible, and use a moderately sized tool to feed. The faster and larger the feed, the smoother the machined surface.
