What are the processing principles for Changzhou mechanical processing?

(1) In order to ensure machining accuracy, rough and finish machining shall be carried out separately. Due to the large amount of cutting during rough machining, the large cutting force and clamping force applied to the workpiece, the large amount of heat generated, and the obvious work-hardening phenomenon on the machined surface, there is a large internal stress inside the workpiece. Assuming that rough and rough machining are carried out continuously, the precision of the finished part will be quickly lost due to the stress spreading from the beginning. Regarding certain parts with high machining accuracy requirements. After rough machining and before finishing, low-temperature annealing or aging treatment should also be arranged to eliminate internal stress.

(2) Reasonable selection of equipment. Rough machining mainly involves cutting off most of the machining allowance and does not require high machining accuracy. Therefore, rough machining should be carried out on a machine tool with high power and low accuracy, while the finishing process requires using a higher machine tool for processing. Rough and fine machining are processed on different machine tools, which can not only fully utilize the equipment capabilities, but also extend the service life of precision machine tools.

(3) On the way to Changzhou's machining process, heat treatment procedures are often arranged. The arrangement of the heat treatment process is as follows: In order to improve the metal cutting and processing functions, such as annealing, normalizing, tempering, etc., it is generally arranged before Changzhou mechanical processing. In order to eliminate internal stress, such as aging treatment, tempering treatment, etc., it is generally arranged after rough machining and before finishing. In order to advance the mechanical functions of parts, such as carburizing, quenching, tempering, etc., it is generally arranged after Changzhou mechanical processing. If there is significant deformation after heat treatment, processing procedures must also be arranged.
