Extra Security for Milling Titanium

The weak link in heavy milling of titanium is often the toolholder. The milling tool might pull out of a shrink fit holder. To permit more aggressive cutting in titanium, Command Tooling Systems is developing a new "Zero Pull" toolholder concept. The shrink fit holder uses locking pins that mate with a groove machined in the endmill to mechanically secure the tool. The new holder design is about to enter beta testing in aerospace machining applications, but the company brought a version of the holder to the show so it could begin telling shops about the Zero Pull concept.
