Testing Tombstones - Using Science to Find the Best Workholding Fixture - Part 1

We all know that when it comes to machining, you’re only as rigid as your weakest link. That’s why AME took to testing their AMROK tombstones with the help of Dr. Tony Schmitz.

Epoxy-mineral tombstones are fairly new to the world of manufacturing, and they are designed to offer a light-weight option for workholding. But do epoxy-mineral tombstones hold their own with more traditional workholding options, like cast iron and aluminum?

We called in Dr. Tony Schmitz to do vibration damping testing in a controlled environment… here’s what he found!
