Application
For clamping tools with straight shanks without loss of concentricity or clamping force up to shank tolerance h10, for economic machining of individual and series parts with extremely high-precision machining results. Ideal for HPC and HSC machining.

Execution
  • 30° trapezoidal thread with polished, extra-long double guide with special anti-friction coating for less friction
  • Clamping forces are evenly distributed across the entire cylindrical shell surface and perfect surfaces are achieved due to optimally absorbed radial forces
  • Precise centring when tightening the clamping nut

Advantage
  • Resistant to fluctuations in temperature and entirely suitable for drying processes and hard milling up to 200 °C
  • Reinforcement of the chuck body over the diameter of the clamping nut ensures outstanding stability with an optimum interference contour
  • Extremely low system concentricity of < 3 µm with the 2 µm ATORN UP collets. With Fahrion 2 µm HPD sealed collets to 80 bar for internal cooling (without sealing washer)
  • Completely enclosed in the chuck cone for optimum stability and even distribution of clamping forces
  • Retention force twice that of conventional collet chucks

Delivery
1x HSK63 ER precision collet chuck (ISO 12164)

The previous standard DIN 69871 was superseded by ISO 12164.
