Application
Produced using an innovative process, the ultra-slim hydro expansion chuck combines the advantages of an expansion chuck and a shrink-fit chuck in a single product.
Execution
- Exceptionally high clamping forces.
- Extremely high temperature resistance (up to 120°C) ensures that the chuck retains its accuracy.
- Slim shrink-fit chuck-style design makes it suitable for narrow interference contours.
- Excellent shock absorption.
- Max. concentricity < 0.003 mm.
- Standard tool changes as with expansion chucks, no need for auxiliary equipment.
- Variable thanks to the use of reducer bushings.
- Balanced to G2.5/25,000 rpm.
- With Balluff chip hole.
