CNC Machined Multi-Step Precision Shaft Sleeve

This cylindrical component features a knurled handle and multi-step outer diameters, commonly used in adjustment mechanisms, positioning assemblies, or locking sections of fixtures for mechanical equipment. The main body includes transition segments of varying diameters and laterally distributed fastening holes. Axial displacement or radial clamping is achieved by rotating the head, meeting the needs for fine-tuning motion components and ensuring rigid fixation in non-standard automated production lines.

The manufacturing process prioritizes the coaxiality of the multi-step outer circles relative to the central axis, as well as the positional accuracy of side mounting holes, to ensure smooth movement and uniform force distribution after assembly. For such slender, multi-feature custom parts, strict control over surface roughness and chamfer consistency on each step is essential to prevent fit interference or stiff operation caused by burrs or tolerance deviations.
