Heat Treatment

Heat furnace

Heat treating is a very key production step during the gear manufacturing process. This can represent up to 30% of the manufacturing costs.

By modifying the physical, chemical and metallurgical properties of the gear, heat treatment can optimize and even extend the life of the gear, making this process a critical one in gear manufacturing. Different methods of heat treatment can improve both surface and core hardness, boost machinability, enhance ductility and strength, minimize distortions, and reduce wear and tear.

Some heat treatment processes target the whole gear, while others may be directed at certain parts of the gear, such as the teeth. Hence, depending on the requirements of the specific gear application, different types of heat treatments may be utilized.
