Classification of inner hole surface hardening inductors

Classification of inner hole surface hardening inductors

1. Surface quenching inductor for inner through hole; 2. Surface quenching inductor for blind hole; 3. Intermediate frequency surface quenching inductor for inner taper hole of spindle.

Inductors used in high-frequency quenching equipment for inner holes seem to be simple, but they are not easy. It requires careful and repeated debugging.
