QUANTITY

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.

Share
  • 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.
