Detailed Description
Precision CNC machined stainless steel shafts are rotational mechanical components designed for power transmission, positioning, bearing support and motion control. Typical designs include stepped shafts, drive shafts, guide shafts, threaded shafts, spindle components and custom transmission shafts.
Materials such as 304, 316 and 17-4PH stainless steel can be selected according to corrosion resistance, mechanical strength and operating environment. CNC turning is typically used to control shaft diameters, shoulders and end features, while milling, drilling, threading or grinding can be added where required.
Critical areas such as bearing seats, seal surfaces and mating diameters can be machined with tighter dimensional and concentricity control. Keyways, cross holes, retaining-ring grooves and internal or external threads can also be integrated into the shaft design.
Available Surface Finishes
- Fine Turned Finish: Standard precision-machined shaft surface.
- Centerless Grinding: Available for controlled diameter and surface quality.
- Polishing: Produces smoother surfaces for visible or low-friction applications.
- Passivation: Improves corrosion resistance of stainless steel.
- Electropolishing: Available for selected clean or corrosion-sensitive applications.
- Black Oxide: Available for suitable steel shaft materials when specified.
Structural & Functional Breakdown
- Bearing Seats: Precision diameters support bearings and rotating assemblies.
- Stepped Diameters: Allow multiple components to be positioned on one shaft.
- Threaded Ends: Support nuts, fasteners and assembled components.
- Keyways & Flats: Transfer torque or prevent component rotation.
- Retaining Grooves: Accommodate circlips and axial positioning elements.
