1. High-Precision CNC Turning Services

Our CNC Turning Services deliver accurate, consistent results for cylindrical parts such as shafts, bushings, pins, sleeves, and threaded components. We support both rapid prototypes and high-volume production runs with strict dimensional control.

• Turning diameter range: Ø2mm to Ø300mm
• Tolerance control up to ±0.005mm
• Supports external/internal threads, grooves, knurling, chamfering

2. Why Our CNC Lathes Perform Better

● Concentricity Control

Our turning centers are calibrated to maintain strict concentricity (≤0.01mm) between internal bores and external diameters—critical for bearing fits and rotating assemblies.

● One-Step Finish Machining

Thanks to dual-spindle and live-tool capabilities, most parts are completed in one setup, reducing tolerance stack-ups and improving cycle efficiency.

3. Application Areas for CNC Turned Parts

• Motor shafts and transmission pins
• Connector housings and sensor shells
• Hydraulic valve stems and threaded couplings
• Medical pins and stainless-steel surgical rods

4. Case Study: Stainless Steel Threaded Adapters

Project Brief

A European customer needed 10,000 stainless-steel adapters with M18 external threads and internal O-ring seats, to be delivered within 3 weeks. Tolerance on the sealing surface: ±0.01mm. Finish: oil-free, passivated.

Our Turning Process Flow

• ① Raw Bar Cutting: Stainless rods pre-cut on automatic saws to length, minimizing vibration during turning.
• ② Turning & Threading: Precision turning and thread cutting using multi-axis CNC lathes with in-cycle gauging.
• ③ Groove + O-Ring Seat: Insert grooving tools applied for uniform depth and finish of seal seat.
• ④ Inspection: Thread gauges, ID/OD micrometers, and roundness check after passivation.
• ⑤ Final Cleaning: Degreased and vacuum-packed in sets of 100 pcs per tray.

5. CNC Turning FAQs

● What’s the smallest diameter you can machine?

We regularly turn parts down to Ø2mm with ±0.01mm tolerance, using specialized collet chucks and high-speed turning centers.

● Can you machine both ends of a shaft in one setup?

Yes, our dual-spindle lathes allow part pickup, machining, and alignment in a single cycle, ensuring perfect symmetry and repeatability.

● What surface finishes can you achieve?

Turning typically achieves Ra 0.8–1.6μm. We can improve surface finishes through polishing or apply coatings such as anodizing, nickel plating, or black oxide.
