Precision ER spring collet

ER spring collet is a kind of cylindrical clamp that can be installed on the milling machine to confine the drill bit or milling cutter. ER spring collet is a fixing device used to fix and reinforce parts that need to be modified.


ER spring collet is an important part of all parts of the clamping mechanism. It is made under tight motion conditions and determines the processing accuracy. Therefore, it is very important to determine the basic parameters of the spring chuck (identification number, cone angle, jaw and identification length) to ensure high working capacity.
