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

  • Extremely 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 damping properties
  • Max. concentricity < 0.003 mm
  • Standard tool changes as with expansion chucks without requiring additional devices
  • Reducer bushings enable various applications
  • Balanced to G2.5/25,000 rpm
  • With Balluff chip hole
