The problem is well known.
You would like to produce a sheet with a large amount of holes. Sheet distortion results due to the small hole spacing. There is no patent solution for it. BUT: there are some
countermeasures!
Fundamentally you should keep in mind that:
- you make the right choice for clearance.
- you should use only sharp /ground tools.
- use an active stripper or fully guided cluster punch
Should all of these points not be enough, there is the option to use tools that relieve sheet stress and warping.
Tooling with sheet stress relief feature
This is a solid tool.
The stripper is produced concave.
(Attention: use only active stripper!)
