Collets are used in manuel and CNC lathes for workpiece clamping. They are installed directly in the spindle or in the collet chuck.
Our collets are used by well-known machine manufacturers, such as CITIZEN, DMG MORI, GILDEMEISTER, HANWHA, INDEX/TRAUB, MAIER, STAR, SCHÜTTE, TORNOS und TSUGAMI.
Dead length collets are used in the main and sub spindle. The collets can be installed in various types of machines, such as turning machines, sliding headstock automatic lathes, multi-spindle machines, conventional lathes, cam-controlled lathes and in special purpose machine constructions.
The collet is clamped via the pressure sleeve, which presses the collet in axial direction against the union nut.
The overgrip collets are often used in production when the diameter to be clamped is smaller than the diameter to be overgripped. The maximum diameter difference to be overgripped should not be larger than 2.5mm. The decisive factors here are the stroke, the clamping length and the machine type which must be individually adapted to the workpiece.
Hydromat collets are used for workpiece clamping as well as in rotary transfer machines such as Eubama, Hydromat and Pfiffner (FFG). Hydromat collets are available with threaded or quick change version. They can also be supplied with a saw burr cut in the clamping area. Suitable for the Hydromat collets, hydromat reducing sleeves, ejector bar, ejector sleeves and stop heads can be manufactured.
Draw-in long nose collets are used for workpiece clamping as well as in all common grinding machines, dividing heads and manuel turning machines. The long nose provides better accessibility to the workpiece.
Clamping is performed by retracting the draw-in collet into the collet sleeve.
The high-precision alignment pins are particularly suitable for checking the axial or radial offset of machine axes or the offset of the main spindle to the sub spindle of the machine geometry.
Furthermore, alignment pins are used for checking the run-out and tumbling on main or sub spindle.
