Precision cylindrical parts from prototype to production. YiguProto is a China-based manufacturer and supplier offering factory-direct pricing, fast quotes, and tight tolerances on every order.
Why buyers choose us
Sourcing turned parts should not feel like a gamble. Here is how our company removes the usual risks.
We inspect every batch in-house and ship a full inspection report with your order. No more guessing whether parts will fit.
Upload your files and quantity. Most quotes are back within a few hours, and never more than 24 hours, with free DFM feedback included.
We support one-off prototypes, small bridge runs, and full production volumes. There is no strict MOQ.
Our CNC and Swiss turning centers hold tolerances as tight as ±0.005 mm, with surface finishes down to Ra 0.8.
Typical lead time is 3 to 10 business days. Rush service is available when your project is on a tight deadline.
Every file is kept confidential. We sign NDAs on request, and your drawings are never passed to any third party.
What it is
CNC turning is a way of making round parts. Think of a shaft, a pin, a bushing, or a fitting.
A metal or plastic rod spins at high speed. A cutting tool moves against it and shaves off material until the shape is right. CNC means the whole process is controlled by a computer, so the result is the same on part one and part ten thousand.
Our lathes also have live tooling. This means we can add holes, flats, grooves, and slots in the same setup, without moving your part to another machine.
Our solutions
One accountable supplier for every step, from drawing to delivered parts.
Standard lathe work for shafts, pins, bushings, spacers, and fittings. Best for simple cylindrical shapes and steady production runs.
Swiss-style lathes for small, long, or very precise parts such as medical pins and watch parts. Tight tolerances and a smooth finish.
Mill-turn machines make complex parts in one setup. Fewer handling steps mean better accuracy and lower cost.
One process covers your first sample and your full production run. No need to switch suppliers as volume grows.

Materials
If your material is not listed, send us the grade. We will check availability for you.
Aluminium, stainless steel, mild steel, alloy steel, tool steel, brass, copper, bronze, titanium, magnesium, zinc, and nickel alloys. We also work with harder grades such as Inconel on request.
ABS, PC, PMMA, POM, PA, PE, PP, PS, PEEK, PTFE, PBT, PVC, nylon, and acetal. A good choice when you need a light, non-conductive, or low-friction part.
Surface finish
Choose a finish for appearance, corrosion resistance, or performance. We will advise on the best match for your part.
Light tool marks remain. The most cost-effective option for hidden or internal parts.
Adds a hard, corrosion-resistant layer. Common for aluminium parts in many colors.
Gives a smooth, bright surface. Useful for parts that must slide or stay clean.
A durable colored layer that protects and brands your part at the same time.
Zinc, nickel, chrome, or other coatings for wear resistance and a clean look.
