Micro Perforating Tip for Folding, Scoring or Perforating Machines

[RCOwlPic]

If this is really how the blade and anvil is made, the mechanical designer screwed up. All set-screw collars are made so the opposing wall allows the shaft to be centered when the screw is tightened.

(If there are some tolerance issues this technique will not help because there is no reason that the tolerance errors are the same for different parts.)

@RCOwlPic In theory you're correct. In practice we've found this technique can indeed turn a troublesome perf job into an acceptable, quality job. Technicians at major folder manufacturers often recommend this technique based on real-world experience in hundreds of shops.

Yes, tolerance errors differ from part to part, but we've found that parts on most machines tend to have errors that are close, perhaps because they are often from the same batch, or from the same manufacturer.
