1. Confirm the diameter, dimension, thickness and material of the disks, Laser cutting forming. 

2. Lathe machining edge 

3. The punch presses the gap 

4. After 900 degrees of High temperature heating molding , quenching, tempering, quenching, finally reach the hardness of the plate #65 manganese steel is 35~40HRC, 30MnB5 and 35MnB5 hardness of 48~52HRC, 

30MnB5 Heat treatment specification: Quenching 860℃-900℃, water cooling; Tempering 400℃-600℃, Top quenching test 880℃±5℃ 

5. After the disks is cooled, it is painting after shot blasting and rust removal
