1. Reasons for Grinding Cracks of Gears Heat Treated in High Frequency Induction Heating Furnace:

Gears are mechanical parts with teeth that can mesh with each other. They have to withstand huge friction during the working process. For this reason, we often use high-frequency induction heating furnaces for heat treatment. However, during the operation process, it is affected by various factors. Gears may have some defects, such as grinding cracks, etc., which will affect the service life of the workpiece.

The gear heat treatment process has an important impact on grinding cracks, the main effects are as follows:
1) When the tempering temperature increases, the tendency of gear wear and tear is reduced. Tempering at 200 °C can reduce the risk of wear and tear to zero. Whether the tempering is sufficient or not is the key factor that determines the tendency of the gear to wear and crack, and sufficient tempering can avoid the occurrence of grinding cracks. It is generally believed that quenching cracks on martensite and grain boundaries are one of the causes of grinding cracks, especially when the distribution and direction of microcracks in martensite are favorable for crack propagation to grain boundaries. The martensitic microcracks often become the crack source of grinding cracks. With the increase of tempering temperature, the microcracks in the martensitic medium decrease.
2) The influence of quenching temperature. The quenching temperature is high, the martensite needle is thick, and there are many microcracks in the martensite, so the risk of grinding cracks is high.

2. Application of Induction Hardening Machine :
1. Various hardware tools, hand tools, such as pliers, wrenches, axes, hammers, axes, screwdrivers, scissors and other standard parts quenching.
2. Various automobile and motorcycle accessories, such as crankshaft, connecting rod, piston pin, sprocket wheel, aluminum
wheel, valve, rocker shaft, small circumference, fork and so on quenching.
3. Machine bed surface quenching.
4. All kinds of hardware quenching, machining. Such as shaft and gear, CAM, chuck, fixture and so on quenching.
5. Metal mold quenching, such as small mold, mold accessories, inner hole quenching, etc.
