LEXIS Polished SSTEEL Dead Length Collet, For Machinery, Machine Application, Size : Customised

Traub collets using for work piece clamping and bar or chuck work. No axial movement while the chuck is clamping. The collets are made from special spring steel. Where possible, by partial tempering the hardness of the taper and clamping bore is approx. 60 HRc. The shank and spring area are hardened to spring. 
Bore smooth and with round grooves from 6.0 mm, serrated in the case of round bores greater than 9.0 mm for higher clamping force. The clamping taper is lightly ground at the slot edges to ease removal of the collets from the mounting thus making possible low undersized clamping. 
The taper of the clamping sleeve should be 15’ per side flatter than the taper angle given in the tables. This frees the collets on release and provides low undersized clamping. In the case of stepped bores or when using collets stops the clamping point should be within the taper of the collet, otherwise the collet will tend to break due to bending stresses.
