ABSTRACT:
The punch, stripper and die holders of a punch press are moved bodily toward an indexable turret and automatically pick up a punch, a stripper and a die from the turret preparatory to being shifted bodily away from the turret to perform a punching operation. When the punching operation is completed, the holders return the tools to the turret, the turret is indexed and then the holders pick up a different set of tools from the turret. Means are provided for shielding vulnerable areas of the holders from debris created during the operation of a plasma-arc torch which is associated with the press. The tools on the turret also are shielded from the debris.
