According to the thickness, disc springs are divided into disc springs without flat bearing (group 1,2) and with flat bearing(group 3). As shown in The Figure and Table below.
| Group | tmm | With flat bearing and reduced thickness | Manufacturing process |
| 1 | 0,2 ≤ t < 1,25 | No | Stamping, cold or hot forming, edge rounding |
| 2 | 1,25 ≤ t ≤ 6,0 | Stamping, cold or hot forming, D and d turninga,edge rounding | |
| 3 | 6,0 < t ≤ 14,0 | Yes | Cold or hot forming, turning on all sides, edge rounding or Stampingc, cold or hot forming, D and d turning, edge rounding |
|
a D and d turning are optional. c Stamping without D and d turning is not permitted. |
