Precision CNC Turning Services from China
Our CNC turning services deliver precision manufacturing solutions for cylindrical components with complex geometries. Using advanced CNC lathes, we handle both simple shafts and high-tolerance rotational parts, meeting tight dimensional requirements down to ±0.01 mm.
We specialize in prototype development and high-volume production, supporting custom designs for aerospace, automotive, medical, and industrial equipment applications.
What Is CNC Turning?
CNC turning is a subtractive manufacturing process that creates cylindrical parts by rotating a workpiece against a stationary cutting tool. It delivers high precision and repeatability, making it ideal for shafts, bushings, fasteners, and other rotational components.
Common materials include aluminum, steel, brass, and stainless steel. The process supports both simple parts and complex geometries, making it suitable for prototypes and low-volume production runs.
CNC Turning Benefits
CNC turning provides reliable solutions for cylindrical parts, with consistent results and flexible options.
High Precision Machining
Achieves tight tolerances down to ±0.01 mm for critical cylindrical components, ensuring consistent quality.
Broad Material Compatibility
Works with common metals including aluminum, steel, brass, and stainless steel to match application requirements.
Support for Complex Geometries
Multi-axis lathes produce parts with contours, grooves, and threads in a single setup.
Flexible Surface Finishes
Supports secondary operations such as polishing, plating, and anodizing to meet functional and aesthetic needs.
Fast Turnaround Times
Efficient production for prototypes and low-volume runs, with short lead times for most orders.

Frequently Asked Questions
Find answers to common questions about our CNC turning services.
What is the minimum order quantity for CNC turning?
We accept both small and large orders. For prototype development, we can produce as few as one piece, while for production runs, we can handle high-volume orders efficiently.
How long does it take to complete a CNC turning project?
Lead times depend on the complexity of the project, order quantity, and current workload. For simple projects, we can often deliver within 1-2 weeks, while more complex projects may take 3-4 weeks. We'll provide a specific timeline when we quote your project.
What file formats do you accept for design files?
We accept various CAD file formats, including DXF, DWG, STEP, IGES, and SolidWorks files. If you have questions about specific file formats, please contact us.
