The large dimensional range in which disc springs are made requires very different production methods.

• Group 1 
  t <1.25, punching, cold forming, rounding-off edges
• Group 2 
  1.25 ≤ t ≤ 6 mm, punching, cold forming, turning and rounding off edges or fine-blanking, cold forming and rounding off edges
• Group 3
  From 6 mm, cold or hot forming, turning all sides, rounding off edges or punching, cold forming, turning and rounding off edges or fine-blanking, cold forming, rounding off edges

Disc springs of group 2 acc. to DIN EN 16983 (previously DIN 2093) can be manufactured acc. to the following alternative processes:

• First the blank is stamped and subsequently the inner and outer diameter are turned to finished size.
• The disc spring is fine-blanked* (according to VDI directive 2906 page 5) and the punching grooves and the burr at the cutting edges are subsequently removed by tumbling/ vibrofinishing.
