The development and application of spring collet is a wide coverage industry. It must be relatively applicable to a variety of machine tool series products, and include products designed to reflect the different characteristics and characteristics between it and the machine tool. However, there is still a widespread misconception that the spring chuck is only used to clamp the rough embryo of cylindrical workpiece. This is also not true. In fact, it can accurately position and clamp almost all kinds of workpieces (or CNC blades), including square or hexagonal workpieces.

In the application of spring collet, the locking angle (or head inclination) size of the design scheme will determine the index value that the clamping force can reach after expansion. The standard finish (or head inclination) has been determined by the machine tool manufacturer and the spring collet manufacturer according to the type of machine tool (such as CNC lathe), the application standard (dynamic and static data) and the main purpose (workpiece and CNC blade).
