What's the use of spring collet?
spring collet is a kind of locking device for clamping cutter or workpiece. It is usually used in drilling and milling machine and machining center. It is mainly used for clamping cutter. The cylindrical clamp is used to clamp the cutter by elastic deformation of the spring. The clamping is simple and convenient, and the accuracy requirement of tool handle is not high. Cylinder clamp is an accessory for tool holder, which is suitable for high speed cutting and high efficiency machining. Good rigidity, clamping depends on nut locking.
Sk tool holder standard is German industrial standard DIN 69871. Machining center spindle taper holes are usually divided into two categories, namely, the universal system with taper of 7:24 And the HSK vacuum system with taper of 1:10. The universal tool handle with taper of 7:24 has five standards and specifications, namely NT (traditional type), DIN 69871 (German standard), IS07388/1 (international standard), MAS BT (Japanese standard) and ANSI/ASME (American standard).
