High precision collet chucks KPS-system

The high precision collet chuck (KPS) is the alternative to hydraulic expansion chucks and shrink chucks. High fl exibility due to interchangeable collets (precision collets System KPS available from Ø 0.5 up to 16 mm). High clamping forces and concentricity lead to top surfaces and longer tool life. Plain clamping nut without grooves for high speed machining. Slim version.

Tool shanks: Cylindrical DIN 1835-1 form A/DIN 6535 form HA, tolerance h . 8 Dedicated clamping size on the nominal diameter. Collets available in steps of 0.5 mm.

Run-out: Maximum runout when measured at a gauge projection of 4×d in relation to the external taper is 5 µm.

Balancing: Fine balancing is standard (G 2.5 30,000 min–1).

Note: KPS-system chucks are delivered as standard without stop end screws. The use of stop end screws is not recommended at high spindle speeds, e.g. over 10,000 rpm.

* The maximum rpm for holders equipped with this clamping system is often restricted by the holder‘s back-end taper type and size.
