ATORN hydraulic expansion chuck HSK63 dia. 20 mm A=80 mm in case set

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 length adjustment (max. V in the drawing)
• Reducing sleeves for flexible application
• Very high concentricity (< 3 µm)
• Coolant pressure up to 80 bar
• Heat-resistant up to 100 °C

Advantage

• Robust version ideal for HPC+HSC machining
• Damping properties to increase service life of 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The previous standard DIN 69871 was superseded by ISO 12164.

Delivery

1x HSK63 hydraulic expansion chuck (ISO 12164) in case set incl. reducing sleeves
