DIN6499 Er32 CNC Collet Inch/Mm,Precision 0.008mm ER COLLET with DIN6499,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 clamping mechanism. It works under intense motion conditions and determines the processing accuracy. Therefore, it is very important to determine the basic parameters of the spring chuck (number of discs, cone angle, jaw and length of disc) to ensure high working capacity.
