If you're going to wholesale bulk cost-effective cnc turned prototypes and production parts made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
Hansheng offer specialized CNC Turning services designed for high-performance rotating components. From simple pins and bushings to complex shafts requiring integrated milling and gear features, we provide the precision needed for your mechanical assemblies to run smoothly.
As a professional gearbox manufacturer,we understand that for a transmission system to work, the shaft's runout, concentricity, and cylindricality must be perfect. Leveraging our high-speed Brother CNC Lathes and precision grinding capabilities, we deliver turned parts that meet the exacting standards of the robotics, automotive, and automation industries.
Core Turning Capabilities
Our facility is optimized for the production of cylindrical parts (OD/ID) with strict tolerance requirements. We offer Mill-Turn solutions, completing complex features in a single setup to maximize accuracy.
High-Speed CNC Turning
Our setup is ideal for both rapid prototyping and volume production of small-to-medium precision parts.
Precision Turning Tolerance: ±0.005mm (Standard), capable of holding ISO h6/h7 shaft tolerances.
Geometric Integrity: We focus on Roundness, Cylindricity, and Coaxiality. We ensure your shafts fit perfectly into bearings without wobble.
Materials: Expert handling of stainless steel (303/304/316),Tool Steel, steel(4140, 4340, ML340), aluminum,titanium , brass, copper, and engineering plastics (PEEK,POM,Delrin (acetal),PEEK,ABS,Nylon,PC,PMMA).
Live Tooling & Mill-Turn Composite Processing
Modern parts rarely just need turning. They need cross-holes, keyways, and flats.
One-Step Manufacturing: Utilizing Live Tooling capabilities, we can drill cross-holes, mill flat surfaces, and tap threads on the side of the part while it is still on the lathe.
Benefit: This eliminates the need for a second fixture in a milling machine, significantly reducing cumulative errors and production costs.
Shaft & Gear Blank Manufacturing
As a manufacturer of harmonic drives, we are experts in turning the "blanks" that become high-precision gears.
Integrated Gear Features: If your turned part requires splines or gear teeth, we can seamlessly transition the part from our lathes to our Kashifuji Gear Skiving Machines or Ningjiang Hobbing Machines.
Workshop equipment
Brother CNC Lathe Machine TC-S2A
The star of our turning floor. Known for its lightning-fast tool changes and high spindle speeds, this machine allows us to produce high volumes of precision turned parts with incredible efficiency. It is particularly effective for aluminum and steel parts requiring complex tapping and drilling.
Precision Cylindrical Grinding
When turning alone cannot meet the surface finish or tolerance requirements (e.g., for bearing seats), we utilize precision grinding to achieve ±0.002mm accuracy and mirror-like finishes.
Supporting Gear Equipment
Ningjiang YK3610Ⅳ and Kashifuji KPS30. These machines allow us to add value to your turned parts by cutting precision gears directly onto the shaft.
Why Choose Our Turning Service?
Concentricity is crucial
In rotating machinery, a wobbling shaft kills performance. Because we build Planetary Gearboxes (Backlash ≤ 3 arc min), we obsess over Total Indicated Runout (TIR). We guarantee that the features on your part are perfectly concentric to the central axis.
Speed & Scalability
Rapid Prototypes: Get functional turned prototypes in as little as 3 days.
High-Volume Production: The workshop is equipped with five or more Brother TC-S2A. Whether you need 500 or 50,000 standoffs, pins, or fittings, we can scale up production instantly with competitive unit pricing.
Wide range of service industries
New energy vehicle electric drive system (motor spindle, reducer gear shaft)
High end automation and robotics (servo motor shaft, harmonic reducer input shaft, bearing seat, robot wrist joint components)
Mold and molding industry (cylindrical components of extrusion screws, die heads, and high gloss molds)
Special equipment and engineering machinery (gearboxes, slewing bearing components, hydraulic valve blocks, high-strength structural components)
The "Gear" Advantage
Most CNC shops have to outsource gear cutting. We don't. If your turned part involves a gear, worm, or spline, we handle it in-house. This reduces your supply chain risk and lead time.
Technical Specifications & Tolerances
We adhere to strict manufacturing standards to ensure every turned part fits your assembly perfectly. While the table below represents our standard capabilities, we specialize in achieving tighter tolerances for critical features upon request.

FAQ
Q: What is the difference between your Turning and Milling services?
A: Turning rotates the workpiece against a stationary tool, ideal for cylindrical parts like shafts, pins, and spacers. Milling rotates the tool against a stationary workpiece, ideal for blocky, flat, or complex 3D shapes. We offer both, and often combine them for complex parts.
Q: Can you do "Swiss Turning" or micro-turning?
A: We have high-precision lathes capable of handling small diameter parts with tight tolerances. Please send us your drawing to confirm if it fits our specific machine capacity.
Q: I need a shaft with a keyway and a side hole. Can you do this?
A: Yes. We use Mill-Turn techniques (Live Tooling) to machine these features in the same setup as the turning operation. This ensures the keyway and hole are perfectly aligned with the shaft axis.
My turned part needs to be hardened. Can you help?
Yes. We handle heat treatment (carburizing, nitriding, induction hardening) and can perform post-heat-treat grinding to ensure the final dimensions are accurate after the material hardens.
Q: What is the maximum precision for turned parts?
A: For direct CNC turning, we hold ±0.005mm. For parts requiring extreme precision (like bearing journals), we use precision grinding to achieve ±0.002mm.
