During the machining of crankshaft, Nazhen will normally carry out two times of heat treatment. After the rough machining of the crankshaft, the first heat treatment will be carried out. And the second heat treatment will be carried out after fine machining. The precision and temperature of the second heat treatment will be set according to the craft of the first heat treatment and blueprint. By adopting heat treatment, the toughness of the crankshaft can be improved and the hardness and wear resistance can also be increased. Thus the crankshaft will not be easily broken off and the service life will be prolonged.
