Custom CNC Turned & Milled Stainless Steel Precision Shaft for Automation Transmission System
Product OverviewThis custom precision shaft is fabricated by combined CNC turning and milling processes. It features multi-step shoulder diameters, internal threaded end, machined keyway slot and special split groove structure. Made from stainless steel, this shaft serves as a core rotary transmission component for automation equipment. Strict concentricity and dimensional tolerance control ensures smooth, stable rotation in continuous-cycle automated machinery. The polished surface minimizes friction and improves wear resistance for long service life.
Key Features- Multi-step shoulder design, internal thread and keyway slot by CNC turn-mill composite machining
- High concentricity control for stable rotary transmission
- Fine polished surface for low friction and anti-corrosion
- Custom keyway size, thread specification and groove geometry based on drawings
- Consistent batch quality for prototype and volume orders
- Good rigidity and wear resistance for continuous motion operation

Q1: What stainless steel grades are available for precision shafts?
A1: We commonly use 304 and 316 stainless steel. 416 stainless steel is available for higher wear requirements.
Q2: Can you guarantee concentricity for long multi-step shafts?
A2: Yes. We use dedicated fixtures and CMM inspection to control concentricity and runout for long precision shafts.
Q3: Can we customize the keyway and internal thread?
A3: Absolutely. We can machine metric or imperial threads and custom keyway dimensions following your CAD drawing.
Q4: What surface treatments are available for stainless steel shafts?
A4: Options include polishing, passivation, black oxide coating, and PVD coating for enhanced wear resistance.

NWe chose ChenRong for urgent steel CNC turning parts for our test fixture. Their rapid service saved our prototype schedule. Steel shafts and sleeves are precisely turned, surface finish is clean, dimensions match our drawing perfectly. Quotation was fast and they kept us updated on production progress. We will use their rapid turning service again.
