OUR CNC TURNING CAPABILITIES
Precision turning for shafts, sleeves and rotational components
CNC turning removes material from rotating workpieces to produce precise cylindrical components, including shafts, sleeves, bushings, pins and threaded parts. With controlled diameters, concentricity and surface finishes, our turning processes support a wide range of metal component requirements.
From prototypes to repeat production, each project is reviewed for manufacturability before machining. Our engineers evaluate part requirements, material selection and tolerance needs to help optimize production reliability and reduce avoidable rework.
Applications
What components can we turn?
Why Tongyong
Work with a CNC turning partner built around confidence.
Behind every turned part is an engineering-led team focused on accuracy, repeatability and getting your project right the first time.
Expert, engineering-led
You work with engineers who review every drawing for manufacturability and suggest improvements before cutting — not a faceless order queue.
Consistent quality, every time
Documented DFM, in-process checks and final inspection mean the 500th part matches the first. Tolerances confirmed against your drawing.
One partner, fewer hand-offs
Milling, finishing, inspection and traceability under one roof reduces suppliers, shortens lead time and keeps your part consistent.

Manufacturing Insights
What “tight tolerance” really costs
Why a single blanket tolerance is the wrong way to spec a part, and how confirming critical dimensions at DFM keeps quality high and cost sensible.
Common questions
CNC turning FAQs
What is the maximum diameter you can turn?
Representative maximum turned diameter is around 400 mm and length up to ~1000 mm. Larger or unusual sizes — send your drawing and we'll confirm feasibility.
What tolerances can CNC turning hold?
General tolerances follow recognized standards; diameters and concentricity are held closely on capable features and confirmed against your drawing at DFM review, then measured and documented.
Can you machine threads and secondary features?
Yes — with live tooling we add cross-holes, flats, slots and internal/external threads in the same setup, improving accuracy and reducing handling.
Can you turn one-off prototypes?
Yes — minimum order is one piece. Prototypes are turned from production-grade material so they validate fit, function and finish before you scale.
What files do you need for a turning quote?
A 3D model (STEP / IGES) plus a 2D drawing for critical diameters, tolerances and finish. A sketch is enough to start.
Ready to machine your turned parts?
Send your STEP, IGES, or DWG files along with your project requirements. Our engineering team will review your CNC turning requirements, assess manufacturing feasibility, and provide quotation and DFM feedback based on your project.
