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. Max. D type Collet chuck Capacity d tightening clamping system size mm D L 1 M S torque max.
