ER-Precision collet chuck BT 30 – 2/20 – 70 ER32
Application:
For mounting straight-shank tools in 2 µm-collets.
Advantage:
- Excellent concentricity in the system (chuck + collet + clamping nut)
- 3 µm radial run-out with a 2 µm clamping nut, 6 µm radial run-out with a 5 µm clamping nut
- Extremely strong holding force (increases the holding power by at least 60% compared to standard ER chuck)
- Plain clamping nut without grooves for high speed machining
