ATORN HSK63 hydraulic expansion chuck (ISO 12164) dia. 20 mm
Brand: ATORN
Art.-no. 23738220
Manufacturer article no. 21040082
EAN 4050293359206
Application
For high precision, centric clamping of milling, drilling and reaming tools – particularly for milling and heavy-duty machining during rough machining.
Execution
- With axial longitudinal adjustment
- Reducing sleeves for flexible application
- Coolant pressure up to 80 bar
Advantage
- Damping properties to increase the service life of tool and machine spindle
- Very high torque transfer (dia. 20 = 400 Nm/dia. 32 = 730 Nm)
- Vibration-damping effect reduces micro-cracks and improves the workpiece surface
- All standard shanks can be clamped (dia. tolerance h6)
Notes
The previous standard DIN 69871 was superseded by ISO 12164.
