What is Metal Spinning?: A metal disc blank or pre-form that is produced by drawing or stamping is concentrically clamped against the spinning mandrel/chuck by the pressurized tailstock. The main spindle then starts to rotate while a spinning roller makes frictional contact progressively reforming the original blank or preform until the metal lies internally on the spinning chuck (paraphrased; verlag moderne industrie AG, Spinning and Flow Forming, 1994).
Benefits of Metal Spinning:
Inexpensive tooling
Structural Integrity
Minimal Scrap
Shorter lead times
