CNC Machined Split Shaft Collar Clamp

Designed for the radial locking and positioning of cylindrical workpieces in precision transmission systems, this shaft collar features a lateral split slot and end-face threaded holes. It is commonly used for coupling connections, lead screw support, or end fixation in tooling fixtures within automated equipment. Its unique split design allows the part to be inserted axially and then tightened onto a smooth shaft or pin via radial contraction force generated by side screws. This achieves rigid, keyless power transmission and effectively prevents relative slippage during high-speed operation.

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 rotational balance after assembly. Since the part involves combined turning and milling operations, special attention is paid to minimizing positional errors caused by secondary clamping. Additionally, the perpendicularity of the end-face screw hole axis to the central axis is strictly maintained to prevent stress concentration or mating surface damage due to tilted loading. The surface undergoes fine polishing to achieve a high-gloss metallic finish, which helps reduce friction and enhance corrosion resistance.
