The chuck you asked for?
Have you hesitated to adopt superior µGrind chuck technology because you have a big stock of Schaublin collets? Now you can get a “super chuck” that uses W20 or W25 collets! We also have a version for Nann 3409 collets. Interested in a B32/B45 version?
- Lets you virtually eliminate both radial and axial runout (weeble-wobble) without special tools or skill
- Lets you change diameters and maintains its precision within 5 µm (0.0002″) without adjustment
- W25 version covers 1 to 25 mm (0.04-1″) diameter range
- W25 version swallows up to 18 mm (0.7″) diameter up to 190 mm (7.5″)

- Suitable for both high production and regrinding
