Why are there still parts processing in molds now

Why is there so much increase in parts now? Moreover, they are widely used in various places. With the current development speed of the industry, mechanical equipment is also relatively good, and the quantity is constantly increasing. Anyway, CNC precision parts processing requires high precision, and the product yield is much higher in terms of manufacturer processing or workmanship.

Factor of processed material: The hardness of the processed material is small, and the greater the plasticity, the more severe the degree of cold work hardening of the material.

The shape factor of the cutting tool: The front angle, edge fillet, and wear behind the CNC machining tool have a significant impact on the cold work hardening layer. When the front angle decreases and the wear on the blade and back increases, the depth and hardness of the cold work hardening layer also increase.

The cutting parameters of CNC parts processing: The changes in cutting speed and feed rate have a significant impact on cold work hardening. When the cutting speed increases, the contact time between the tool and the precision workpiece is short, the degree of plastic deformation is small, and the hardening layer and hardness are reduced. As the feed rate increases, the degree of plastic deformation increases, and the degree of surface cold work hardening increases.

The above are the main factors that affect the cold work hardening of CNC parts during machining. These phenomena may occur due to these factors. As long as the above factors are avoided, the hardening phenomenon will not occur. Therefore, it is necessary to pay more attention during machining.
