Integral surface hardening equipment for large-diameter gears

The overall surface hardening of the large-diameter gear, energy-saving and electricity-saving, uniform hardening layer, moderate hardness, effectively improving the wear resistance and service life of the gear during use.

The quenching has super-audio frequency quenching, and the quenching layer is 1-3mm. Intermediate frequency quenching, quenching layer 2-6mm.
