 Total system runout TIR ≤3 μm @ 3 x D

Our holistic system consists of an micRun colletholder, collet and clamping nut. All components together ensure best runout and accuracy.

 Colletholder runout TIR ≤1 μm

Measured from inner taper to outer taper.

 Taper accuracy AT3

Better spindle-to-holder fit and accuracy.

 Surface finish max. Ra 0.25

Achieve high clamping force and high transferable torque.

 Balancing

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

 MR clamping nut included in delivery

Guarantees highest clamping force and best balancing.

 Vibration dampening

Our holders offer good vibration dampening to sustain a high surface finish and can help prevent chatter.

Expert advice

We recommend tightening the clamping nuts using a torque wrench. The overview of the recommended tightening torque is available for download in the media center.
