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The previous standard JIS B 6339 MAS BT was superseded by ISO 7388-2.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
