Processing principle of machining:

(1) In order to ensure the machining accuracy, rough and finish machining are carried out separately. Because during rough machining, the cutting amount is large, the cutting force and clamping force of the workpiece are large, the calorific value is large, and there is a significant work hardening phenomenon on the machined surface, there is a large internal stress in the workpiece. If the rough machining and rough machining are carried out continuously, the precision of the finished part will be lost quickly due to the redistribution of stress. For some parts requiring high machining accuracy. After rough machining and before finishing machining, low-temperature annealing or aging treatment shall also be arranged to eliminate internal stress.

(2) . reasonably select equipment. Rough machining is mainly to cut off most of the machining allowance and does not require high machining accuracy. Therefore, rough machining should be carried out on machine tools with high power and low precision, while finishing process requires high-precision machine tools. Rough and finish machining are processed on different machine tools, which can not only give full play to the equipment capacity, but also prolong the service life of precision machine tools.

(3) Heat treatment process is often arranged in the machining process route. The position of heat treatment process is arranged as follows: in order to improve the cutting performance of metal, such as annealing, normalizing, quenching and tempering, it is generally arranged before machining. In order to eliminate internal stress, such as aging treatment, quenching and tempering treatment, it is generally arranged after rough machining and before finishing machining. In order to improve the mechanical properties of parts, such as carburizing, quenching and tempering, it is generally arranged after machining. If there is large deformation after heat treatment, the final processing procedure must be arranged.
