Shafts and Pins
Stepped shafts, motor shafts, locating pins, guide pins, and rotational mechanical parts.
CNC Turning
CNC Turning Services for Shafts, Sleeves, Fittings, and Rotational Parts
EASEMFG provides CNC turning for precision rotational components such as shafts, sleeves, bushings, spacers, fittings, threaded parts, and cylindrical metal or plastic components. Turning is suitable when the main geometry is generated around a rotating axis.
When Should You Choose CNC Turning?
Round Part Geometry
Turning is suitable for parts with cylindrical, stepped, tapered, threaded, or concentric features.
Efficient Rotational Cutting
The workpiece rotates while the cutting tool shapes the outer diameter, inner diameter, grooves, faces, and threads.
Stable Dimensional Control
Turning is practical for shafts, sleeves, spacers, bushings, and fittings with repeatable diameter requirements.
Prototype to Batch Work
Suitable for single samples, engineering validation, and low-volume or batch production.
Typical CNC Turned Parts
Typical part types depend on the drawing, material, tolerance, surface finish, quantity, and assembly requirements.
Sleeves and Bushings
Precision sleeves, bushings, spacers, collars, and bearing-related support parts.
Fittings and Threaded Parts
Threaded connectors, adapters, nozzles, nuts, couplings, and round hardware components.
Project Review Focus
Before production, the drawing, CAD model, material, tolerance, surface finish, and inspection points should be reviewed together.
| Review Item | Why It Matters | Typical Check Points |
|---|---|---|
| Outer and Inner Diameter | Diameter accuracy affects assembly fit, sliding fit, bearing fit, and sealing surfaces. | OD, ID, concentricity, roundness, step transitions. |
| Thread Features | Threaded areas need clear specification for pitch, depth, tolerance, and mating part compatibility. | Internal threads, external threads, thread relief, chamfer. |
| Material Behavior | Material affects tool wear, surface finish, burr formation, and deformation risk. | Stainless steel, aluminum, brass, copper, plastics. |
| Surface Finish | Rotational parts often have visible or functional sliding surfaces. | As-turned finish, polishing, passivation, plating, deburring. |
CNC turning is most suitable when the part is mainly rotational. If the part also requires side holes, flats, slots, or off-axis milled features, turn-mill machining may be more practical.
