Metal Spinning  

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 perform 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
Metal Spinning Capacities:
  Up to 5/8" thick and 100" maximum blank diameter for aluminum
  Up to ¼" thick and 100" maximum blank diameter for copper and brass
 
Up to 3/16" thickness and a 100" maximum blank diameter for stainless steel and nickel
