1. Product Overview


Our CNC turning parts are high-precision rotational mechanical components manufactured by automatic CNC lathe machining technology. Specialized in processing rotary symmetrical parts such as shafts, bolts, sleeves, nuts, threaded fittings, and cylindrical housings, our CNC turning service delivers high dimensional accuracy, excellent concentricity, and consistent surface finish. Compared with conventional lathe processing, computer-controlled turning effectively eliminates manual errors, ensuring outstanding batch consistency and interchangeability.

We provide custom CNC turning solutions for standard and non-standard precision parts, supporting rapid prototyping, small-batch customization, and large-volume mass production. All turning components strictly comply with ISO 9001 quality system and RoHS environmental standards, widely serving machinery equipment, electronics, automotive, hydraulic pneumatic, medical, and instrumentation industries.


2. Core Product Advantages


  • High Rotary Precision & Concentricity: Professional CNC turning ensures precise roundness, concentricity and straightness. Standard tolerance reaches ±0.05mm, and ultra-precision tolerance can be controlled within ±0.01mm, fully meeting the matching requirements of high-precision rotating mechanical structures.
  • Excellent Batch Consistency: Adopting automated numerical control programming and one-time forming processing, the size deviation of batch products is extremely low. The interchangeability of parts is strong, which greatly reduces assembly failure rate and after-sales costs for customers.
  • Smooth Surface & Standard Thread: Optimized turning tool path and high-speed cutting technology make the product surface burr-free and smooth, with surface roughness up to Ra0.8. All threads, grooves and steps are processed in place at one time with standard specifications and high fitting accuracy.
  • Wide Material & Specification Adaptability: Support turning of aluminum alloy, stainless steel, carbon steel, copper alloy, titanium alloy, POM, ABS and other metal and plastic materials. Customized processing of various standard and special-shaped rotary parts is available.
  • Cost-Effective & Fast Delivery: Automated production improves processing efficiency and saves labor costs. Mature production process shortens the delivery cycle, providing customers with high-quality and cost-effective precision turning parts.
