The collet chuck for 50000190 is a variation of the exchangeable tooling specially used on JET turning equipment. The tooling is used on lathes of models GHB-1330A, GHB-1340A, GH-1440W-3, RML-1440 and RML-1440V, as well as for work on equipment of the ZK, ZX and ZH series. The device is designed for fixing collets with dimensions 3-25 mm. and subsequent processing of small parts. C5 collets used for clamping parts are designed to work with parts that already have a machined surface. Uniform clamping action of the collet is ensured by turning the key. The chuck is installed on the tailstock of the machine.
