Type KSKF Power-Operated Collet Chucks

The innovative collet chucks feature short changeover times from external to internal clamping and high degrees of precision and rigidity.

for workpiece clamping of bar and chucking works
highest clamping forces and rigidity (types KSKF, KSKF-A)
axially fixed clamping head, less rigidity (type KSKF-AF)
an intermediate flange is required for all collet chucks type KSKF. Flanges are available in various dimensions and for a variety of spindle noses
all collet chucks type KSKF are designed in a way that a segment clamping mandrel can be bolt on via the bores at the face end without major modifications of the chuck
quick change capability of clamping heads

Drawback collet chuck with through-hole for bar machining: the clamping head is pulled into the chuck during clamping and provides high clamping forces and high rigidity. The collet chucks work very precisely and feature an easy set-up as well as high running accuracy.

Type KSKF-AF is equipped with a fixed clamping head and can be used for through as well as for stop clamping. The pressure sleeve is pushed over the axially fixed clamping head. Type KSKF-AF offers a lesser stiffness than that achieved with types KSKF and KSKF-A.

ZWISCHENFLANSCHE

The intermediate flanges match the collet chuck types KSKF, KSKF-A und KSKF-AF. Explanation first column: Z-140 means cylindrical mount with diameter 140; A-5 means spindle nose with short taper mount size 5 and so on.

INNENSPANNUNG FÜR SPANNFUTTER

The collet chuck types KSKF, KSKF-A and KSKF-AF make possible the change-over to internal clamping within very short time. A new set-up is no longer necessary as the collet chuck remains on the machine. A standard segment mandrel equipped with a fast changing mechanism is inserted – the hardened steel segments offer a high level of wear protection. High clamping forces are achieved with these segment mandrels, and the vulcanized clamping sleeve covers a large clamping range.

The exchangeable insert for internal clamping can also be used on stationary collet chucks type MZ.
