Art.-no. ZR23733751
Manufacturer article no. 21044989
EAN 4050293433715
Application
For high-precision and centric clamping of milling, drilling and reaming tools – particularly with milling and heavy-duty machining during rough machining.
Execution
- Concentricity tolerance < 0.003 mm.
- With axial longitudinal adjustment.
- Reducing sleeves for flexible application.
- Coolant pressure up to 80 bar.
- Heat-resistant up to 100°C.
Advantage
- Robust version ideal for HPC+HSC machining.
- Damping properties to increase the service life of the tool and machine spindle.
- Very high torque transfer (dia. 20 = 650 Nm).
- All standard shanks can be clamped (dia. tolerance h6).
- Vibration-damping effect reduces micro-cracks and improves the workpiece surface.
Notes
The previous standard DIN 69871-1 was superseded by ISO 7388-1.
Delivery
1x hydraulic expansion chuck SK40 (ISO 7388-1) in case set; incl. reducing sleeves.
