Custom Non-Standard Shaft Sleeve Connector

This cylindrical component features a central through-hole and lateral slots, typically serving as a shaft sleeve, locating pin seat, or connection assembly in mechanical transmission or support systems. Characterized by its rotational symmetry, the part has flat end faces and asymmetric machined flats on the side, designed to fit specific assembly spaces and achieve axial or radial fixation.

Strict requirements for coaxiality and internal bore surface finish ensure stable mating clearance during high-speed rotation or reciprocating motion. The lateral milled flats and slot structures increase the difficulty of secondary clamping positioning; therefore, relative positional tolerances between features are strictly controlled to prevent dimensional deviations caused by datum transformation. Surface treatments, such as deburring and chamfering, directly impact assembly smoothness and aesthetic quality.

Leveraging 5-axis CNC Swiss-type lathes and automatic lathes, we achieve efficient mass production of these complex, irregular shaft parts, ensuring one-time forming precision for inner/outer diameters and stepped surfaces. Equipped with 2.5D video measuring systems and roughness testers, we perform full or sampling inspections for bore tolerance, flatness, and surface texture as per drawing requirements. We support material selection (e.g., stainless steel, carbon steel, alloy steel) and process evaluation based on customer-provided CAD drawings, offering stable delivery solutions from prototyping to mass production.
