How to install ER spring Collet:
The spring chuck tool holder uses the displacement of the tapered reducing sleeve to clamp the tool. It is usually used in the inner hole of the spindle. A collet is a cylindrical fixture mounted on a machine that can be used to secure parts for manufacturing or inspection. Before installing the spring collet, first install the spring collet into the nut, then lock the end with the spring collet on the nut and gently screw it on the spindle. Remember to clean the threaded portion of the collet and lock nut. During the installation of the chuck, the chuck and nut should be tilted at a certain angle, and then gently placed into the slot.
