ATORN - ATORN precision collet chuck HSK63 (ISO 12164) ER25 (1-16 mm) A=160 mm

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)

Notes
The previous standard DIN 69871 was superseded by ISO 12164.
