What are the requirements of CNC precision parts processing for the appearance and quality of the finished products

The sequential arrangement of precision part CNC processing shall be considered according to the structure and wool culture of the part, positioning, division and fixture, and the focus is that the workpiece rigidity cannot be damaged.Therefore, the milling process of the last process cannot affect the positioning and loading of the next process, and other CNC processing processes should also be considered. 

In the process of the same clip, the small rigid damage of the workparts should be arranged first. The processing part can be divided into the shape of the curved surface according to the structural characteristics of the inner cavity and the surface plane.Process the inner cavity first, then locate the surface processing plane, then process the curved surface, and continue to process the hole.This can reduce the number of knife changes, clamps, save time, and reduce the error.First processed into simple geometry, low precision coarse processing, and then processed into complex geometry processing with high precision.Do fine processing.
