What is the division method of NC milling machine # NC machine tool # processing technology?

Division method of machining process of CNC milling machine The machining object of CNC milling machine is different according to different machine tools. Vertical CNC milling machine is generally suitable for machining plane cams, templates, plane or three-dimensional parts with complex shapes and internal and external cavities of molds. Horizontal CNC milling machine is suitable for machining box, pump body, shell and other parts. Machining parts on CNC milling machine is a centralized process, and generally all processes can be completed by one clamping. According to the characteristics of CNC machine tools, in order to improve the service life of CNC machine tools, maintain the accuracy of CNC milling machines and reduce the processing cost of parts, the rough machining of parts, especially the datum plane and positioning surface of parts, is usually carried out on ordinary machine tools. The division of machining process usually refers to the principles and methods of process division in CNC studio website. The commonly used methods are as follows:

(1) tool centralized sorting method This method divides the working procedures according to the tools used, and processes all the parts that can be processed by the same tool before changing the tools. This method can reduce the number of tool changes, shorten the auxiliary time and reduce unnecessary positioning errors.

(2) According to the shape and dimensional accuracy of parts and the principle of separating rough machining from finish machining, rough machining, semi-finish machining and final finish machining are carried out.

(3) Processing parts sequence, that is, processing plane and positioning surface first, and then processing holes; Machining simple geometric shapes first, and then machining complex geometric shapes; The parts with lower precision are processed first, and then the parts with higher precision are processed.
