What Are The Processing Principles Of Machining?

Dec. 18, 2018

First, in order to ensure the processing accuracy, coarse and fine processing is best carried out separately. Because of the large amount of cutting during roughing, the cutting force and clamping force of the workpiece are large, the heat is generated, and the machining surface has a significant work hardening phenomenon. There is a large internal stress inside the workpiece. If rough and rough machining Continuously, the precision of the finished part will be quickly lost due to the redistribution of stress. For some Machine Parts Processing with high machining accuracy requirements. After roughing and prior to finishing, a low temperature annealing or aging treatment should be arranged to eliminate internal stresses.

Second, the rational selection of equipment. The rough machining of mechanical parts processing factory mainly cuts off most of the machining allowance and does not require high machining precision. Therefore, rough machining should be carried out on machine tools with high power and low precision. The finishing process requires Higher precision machine tooling. The roughing and finishing are processed on different machine tools, which can fully utilize the equipment capacity and extend the service life of the precision machine tool.

Third, in the Precision Aluminum Parts Processing route, heat treatment processes are often arranged. The arrangement of the heat treatment process is as follows: in order to improve the cutting performance of the metal, such as annealing, normalizing, quenching and tempering, etc., it is generally arranged before the machining. In order to eliminate internal stress, such as aging treatment, quenching and tempering treatment, etc., it is generally arranged after roughing and before finishing. In order to improve the mechanical properties of the parts, such as carburizing, quenching, tempering, etc., it is generally arranged after the machining. If there is a large deformation after heat treatment, the final processing procedure must be arranged.
