High-perf. hydr. expansion chuck BT40 (ISO 7388-2) 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.
• 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The previous standard JIS B 6339 MAS BT was superseded by ISO 7388-2.

Delivery
