1. For hardening, hardening depth is deeper, the frequency of induction machine is lower; hardening depth is shallow, the frequency of induction machine is higher.
Hardening depth: 0-1.5mm 40-50KHz (High frequency, Ultrasonic frequency machine)
Hardening depth: 1.5-2mm 20-25KHz (Ultrasonic frequency machine)
Hardening depth: 2.0-3.0mm 8-20KHz (Ultrasonic frequency, medium frequency machine)
Hardening depth: 3.0-5.0mm 4-8KHz (Medium frequency machine)
Hardening depth: 5.0-8.0mm 2.5-4KHz (Medium frequency machine)
2. For Forging, diameter of work piece is bigger, the frequency of induction machine is lower
Φ4mm 100-500KHz (High Frequency machine)
Φ4-16mm 50-100KHz (High Frequency machine)
Φ16-40mm 10-50KHz (Ultrasonic frequency machine)
Φ40mm 0.5-10KHz (Medium frequency machine)
