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
Advantage
- Advantage of BT-FC (face contact) compared to BT standard tool holders
- Highly precise tool change due to flat face on the collar. Increased rigidity and bending resistance
- The planar contact face on the collar prevents slipping in axial direction at very high speeds. Higher VC minimises vibrations
- Improved surface quality on the workpiece. Longer tool service life and reduced tool costs
- More efficient heavy-duty machining
Notes
The previous standard JIS B6339/MAS BT was superseded by ISO 7388-2.
