ATORN high-perfor. hydraulic expansion chuck BT40 dia. 20 mm A=72.5 mm 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 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
• 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The previous standard JIS B 6339 MAS BT was superseded by ISO 7388-2.

Delivery

1x high-performance BT40 hydraulic expansion chuck (ISO 7388-2) in case set incl. reducing sleeves
