JB 5556-1991Spring collets - Types and parameters (English PDF)

JB 5556-1991 is the English-translated version of 弹簧夹头 型式和参数.

This standard specifies the types of spring collet and the parameters that define them. It sets out the forms in which collets are made and the dimensional parameters that have to be stated for each form, so that a collet can be identified and ordered without ambiguity. The standard applies to the spring collets used on metal-cutting machine tools and on machine tool accessories. It is read together with the rules on the threads used on collets, which it cites as normative references.
