Analysis on the factors of machining hardening of Suzhou cnc parts

       Many of the cnc processing enterprises in Suzhou have encountered the problem of tough parts. The next small series explains why the cnc parts are tough. Cnc hardware parts processing technology In order to reach the accurate surface of the processing parts, the demand for the processing of the dream and the precise forming activities. However, in the essence of work, accurate mechanical CNC machining process is difficult to complete, and there is a big gap between the value of the dream and the dream value. If you want to seek accurate comments, it will often affect the processing efficiency and the expected economic benefits. .

　　The key factors affecting the cnc parts processing cold work toughness are as follows:
1 Raw material factors to be processed: The hardness of the raw materials to be processed is small, and the higher the plasticity, the tighter the hardness of the raw materials.
2 Form factor of the tool: The front angle of the cnc machining tool, the rounded corner of the cutting edge and the amount of wear behind the tool have a great influence on the cold hard layer. When the rake angle is reduced and the amount of wear of the cutting edge and the trailing edge is increased, the depth and hardness of the cold hard layer are also increased.
Cutting factor for 3cnc part machining: The change of cutting speed and feed rate has a great influence on the cold hardening. When the cutting speed is increased, the contact time between the tool and the workpiece of the careful part is short, the plastic deformation level is small, and the tough layer and hardness are reduced. The feed rate is increased, the plastic deformation level is increased, and the surface is cold and hardened.
Therefore, as long as the factors appearing above are correctly prevented, there will be no problem that the cnc machined parts are tough.
