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.
