Methods and characteristics of CNC precision parts processing
CNC precision parts processing is an advanced processing skill in today's machinery manufacturing industry. It inputs the CNC program of the machined parts into the CNC machine tool, and the machine tool automatically processes the workpiece after receiving the CNC program. CNC machining skills can effectively solve the complex and small-scale and changeable processing solutions of hardware parts, and meet the needs of modern production.
The CNC machining process involves tool selection, cutting parameters and tool paths. CNC machining technology is the core content of CNC programming. Only by selecting the NC program with less processing time and the smallest tool path, can high efficiency and high quality products be obtained. CNC machining process can be divided into rough machining, corner cleaning, and finishing. When roughing non-standard parts, a larger tool should be used, and a large amount of workpiece allowance should be quickly cut off at the maximum power of the machine tool to roughen fine parts. The principle of knife selection is mainly to consider whether the chamfered arc surface of the product is too small. After selecting the knives, the knife length is determined. In principle, the tool length should be greater than the machining depth.
The tools we use all have a point of view, and generally need to clear the angle on the step axis. We mill an undercut where we need to clear the corner.
The advantages of this method are as follows: First, it is convenient for the grinding shaft of the grinder to quickly retreat the grinding wheel, and the length will not be affected by grinding the end face. Second, the end face will be completely touched during assembly, and the end face will be smaller.
