Corner radii on punches
A general problem is the wear on the corners on punches with sharp corners such as squares, triangles, etc.
|
|
|
PASS Standard:
In order to reduce this corner wear, we generally grind a radius of R = 0,15 mm (.006") on all such punches.
|
|
|
It is advised to increase the edge radius for stainless steel applications (e.g. R = 0.35 mm (.014") or as large as possible).
