Advantages of vacuum quenching of induction parts heating surface in CNC machining:
1. The heat source is on the surface of the workpiece, the heating speed is fast, and the thermal efficiency is high
2. The workpiece is not heated as a whole, so the deformation is small
3. The workpiece heating time is short, the surface oxidation decarburization amount is small
4. The surface hardness of the workpiece is high, the notch sensitivity is small, and the impact toughness, fatigue strength and wear resistance are greatly improved. It is beneficial to realize the potential of materials, save material consumption and increase the service life of parts
5. The equipment is compact, easy to use and good working conditions
6. Facilitate mechanization and automation
7. Not only for surface vacuum quenching but also for penetration heating and chemical heat treatment.
