CNC Precision Milling Collet Assembly

Designed for the assembly needs of precision transmission and positioning modules, this disc-shaped structure features a central through-hole and lateral split slots. It typically serves as a radial locking mechanism for rotating shafts or a workpiece clamping unit. The part body has a cylindrical shape with end-face threaded interfaces, utilizing elastic deformation from the lateral opening to achieve keyless connections. It is commonly used in couplings, lead screw support seats, or end-fixing stages of non-standard tooling fixtures in automated equipment.

The core of the manufacturing process lies in controlling the coaxiality between the outer diameter and inner bore, as well as the parallelism of the split slot sides, to ensure uniform clamping force distribution and smooth motion after assembly. Due to the machining of multi-faceted features (such as side threaded holes and end-face counterbores), high-rigidity CNC machining centers are required for multi-step fixturing. Priority is given to ensuring positional tolerances of mounting holes relative to the central axis, preventing assembly interference or uneven stress caused by hole deviations.
