OPERATION
Correct use of the tool
Die selection
It is important that the die to be used is correct for the
thickness of the workpiece to be punched. Punching the
workpiece of 4 mm (5/32") to 8 mm (5/16") thickness
using a die for thinner workpiece can cause the punch
to jam in the workpiece. This is due to the smaller clear-
ance between the die and punch. In such a case, the
workpiece will be pulled up by the retracting punch as
shown in the figure. Special care should be taken when
punching flat bar of mild steel, aluminum and copper.
► 1. Workpiece
Correct use of the stripper
Do not position the workpiece with one end or both
ends unsupported by the stripper. If the workpiece is not
properly supported, it will move when the punch returns.
It may cause the punch to jam and damaging the tool.
