Heat treatment method of CAM
The heat treatment methods of the CAM mainly include quenching and tempering. Quenching can greatly improve the hardness of the CAM surface, but it may cause cracking, deformation and other phenomena on the CAM surface, which needs to be tempered after quenching. Tempering can improve the toughness and wear resistance of the CAM and make its surface hardness moderate.
CAM hardness and wear resistance test
The hardness and wear resistance of the CAM can be tested using Rockwell hardness tester and wear testing machine. Rockwell hardness tester can test the surface hardness of the CAM, and the wear tester can simulate the wear of the CAM during use, so as to obtain its wear resistance.
Influence of heat treatment on hardness and wear resistance of CAM
After quenching the CAM, its surface hardness can be greatly improved and its service life can be effectively extended. The tempering treatment can improve the toughness and wear resistance of the CAM, so that it is not easy to break and wear during use. It is found that the hardness and wear resistance of the CAM can be improved under proper quenching and tempering conditions.
CAM heat treatment precautions
When conducting CAM heat treatment, the following points need to be noted:
1. Control the heat treatment temperature and time, select the appropriate quenching medium.
2. Reasonably design the shape and size of the CAM to avoid deformation and cracking.
3. Choose the appropriate tempering temperature and time, and do not over-temper.
4. Strictly control the temperature and atmosphere in the heat treatment process to prevent surface oxidation and pollution.
conclusion
The heat treatment of the CAM can significantly improve its surface hardness and wear resistance, and provide better protection for its use in mechanical transmission. In the CAM heat treatment need to pay attention to the above points, so as to ensure the stability and reliability of the heat treatment effect.
