Whenever possible isolate the coining anvil from other die blocks. This will eliminate transfer of shock to piercing stations. Actually, die sections should be separated in all types of tooling for the same reason, especially with fragile punches. All coining dies require lubricant. Formulate the proper stamping lubricant suited to the application.

A typical setup used for blanking is shown in Fig 5.4. Fig 5.4 Blanking punch and die. The clearance between the die and punch can be determined as c = 0.003 t. t where t is the sheet thickness and t is the shear strength of sheet material. For blanking operation, die size = blank size, and the punch is made smaller, by considering the clearance.
