ATORN high-performance hydraulic expansion chuck SK40 dia. 12 mm A=50 mm

Application

For high-precision and centric clamping of milling, drilling and reaming tools – particularly with milling and heavy-duty machining during rough machining.

Execution

• With axial longitudinal adjustment
• Reducing sleeves for flexible application
• Very high concentricity (< 3 µm)
• Coolant pressure up to 80 bar
• Temperature-resistant up to 100 °C

Advantage

• Robust version ideal for HPC+HSC machining
• Damping properties to increase service life of tool and machine spindle
• Vibration-damping effect reduces micro-cracks and improves the workpiece surface
• All standard shanks can be clamped (dia. tolerance h6)
• Very high torque transfer (dia. 20 = 650 Nm/dia. 32 = 890 Nm)

Notes

The previous standard DIN 69871-1 was replaced by ISO 7388-1.

Delivery
