Features and benefits

 Total system runout TIR ≤3 μm @ 3 x D

Our holistic system consists of a powRgrip colletholder and collet. All components together ensure best runout and accuracy.

 Colletholder runout TIR ≤1 μm

Measured from collet cavity to outer taper.

 Surface finish max. Ra 0.25

Achieve high clamping force and high transferable torque.

Balancing

100% balanced G 2.5 @ 25,000 rpm/<1gmm.

 Vibration dampening

Our holders offer a good vibration dampening to sustain a high surface finish and can prevent cutting force alterations.

 Matched tooling system for best fit

For highest precision and best results the entire machining system counts. Therefore our components are carefully matched for optimum fit and accuracy. This guarantees the best runout and balance.
