Round and flat features on one part — made in a single setup at our China factory. Get a factory-direct quote within 24 hours.
The problem
Round features need a lathe. Flat features need a mill. Send the part to two shops and you wait twice as long.
With YiguProto as your China manufacturer and supplier, one team does both — turning and milling — under one roof.
The basics
Two simple ideas. Turning makes round parts. Milling makes flat parts. Together they finish most precision components.
Turning spins the part against a fixed cutting tool. It is the best way to make round features — shafts, pins, bosses and threads.
Milling spins the cutting tool against a fixed part. It is the best way to make flat faces, slots, pockets and holes.
Most parts need both. We run both on one turn-mill machine, in one setup, so your part never waits in a queue at a second shop. That is the heart of our machining solutions.
Fewer setups means fewer chances for error. We hold ±0.01 mm, and tighter on request.
No shipping parts between two shops. Finished parts in 3 to 8 business days.
One setup saves machine time and labor. Those savings go straight to you.
Roundness and position stay true when the part is never unclamped.
Materials
Metals and engineering plastics, in stock and ready to run. Pick a grade and we will confirm the best fit for your part.

More services
Turning and milling is one step. We also handle the steps before and after it, so you deal with one supplier for complete machining solutions.
Finishing
Add a finish to your turned and milled parts without sending them anywhere else.
Industries
We make turned and milled parts for teams that cannot afford a bad batch.
Lightweight brackets, fittings and structural parts in aluminium and titanium.
Aerospace parts →Save money
Small changes to your design can cut the price without hurting quality.
A complete drawing with tolerances avoids back-and-forth and rework.
Aluminium costs less and cuts faster than titanium. Use it when you can.
Only tighten the features that need it. Loose tolerance means lower cost.
One setup covers many parts. A slightly larger batch spreads the cost.
