Punching Thick Material

Thick Material Punching Considerations

3/12/2020

By implementing the suggestions outlined here when hitting thicker gauge material you should find you have fewer problems when running parts, resulting in less down time and great production. 

Check your Tonnage

Get in the habit of calculating tonnage whenever the material thickness is outside of your normal practice. Download Tonnage Calculator.

Consider a Coating

Coatings can be quite beneficial, especially when your hole size is near the material's thickness in size – 0.125 round hitting 0.105 material for example. View Coating Solutions.

Give up Grind Life for Strength 

By reducing the tool’s standard straight before radius (SBR) and increasing the tool blend radius, you add strength to the tip of the tool but sacrifice some grind life. 

Upgrade to an Insert Design 

By upgrading to the insert design, generally used for cluster punching, you have more puch steel options available to you, which is helpful if your material is either tough or abrasive. Explore Insert Design Tooling.

Increase Station Size

When forming thick material, consider going to a larger station. Larger station tooling allows for more surface and holding force as well as a longer tool stroke.
