Toolholders

Get A (Tight) Grip

High toolholder gripping torque reduces the likelihood that a tool will slip within a toolholder during a cutting operation. A mechanical toolholder design provides a very high gripping torque via a worm gear that compresses a shallow-taper collet tightly around a tool shank.

Vacuum Workholding Method Fits New Machining Strategy

Increased demand for armor plating components led this shop to completely revamp its machining technique. Rather than machining individual workpieces, the shop produces multiple components nested in an aluminum plate. A custom vacuum workholding system plays a significant role in this new strategy.
