Automotive Workpiece

Outer Race of Constant Velocity Joint/Hub Bearing Hardening and Tempering Equipment

Out race of Constant Velocity Joint Hardening and Tempering Equipment

This machine is applicable to the induction hardening of various parts of constant-velocity universal joints outer race/automobile hub bearing. The machine adopts intelligent CNC system centralized control. The work-piece moving and turning in the process of loading, unloading and processing are completed by the manipulator, while the station rotation is completed automatically by the rotating table. The equipment is equipped with 2 induction hardening stations and 1 tempering station, which can finish the induction hardening and tempering of different parts of the stations. The heating power adopts advanced transistor solid-state power with full digital control technology, which has perfect protection function and digital parameter setting and display screen. The special process parameters management monitoring system can record all data of the monitoring system in a real time, and have the function of historical data query. The optional online laser printing function and online nondestructive testing system are available for the equipment. The equipment has high intelligence and processing efficiency.
