Your direct factory for CNC machining in China
Superapid is a CNC machining manufacturer in China that makes precision metal and plastic parts for prototypes and production. You deal with the engineers who program and run the machines, not a marketplace or a trading agent. That means faster quotes, direct technical answers, and no middleman margin in your price.
We supply aerospace, automotive, medical, electronics, robotics and consumer product teams. Whether you need one part to check fit or several thousand for production, we review every file, flag manufacturability issues before cutting, and ship worldwide.
Direct from our factory: 3-, 4- and 5-axis milling, CNC turning and tolerances down to ±0.01 mm. One prototype or 10,000+ production parts, quoted by the engineers who will make them.

CNC milling services in China
Our 3-, 4- and 5-axis milling centers cut complex shapes, tight-tolerance features and multi-face parts. More axes mean fewer setups, which improves accuracy and lowers cost on complex geometry.
- 3-axis milling: flat faces, pockets, slots and holes
- 4-axis milling: cross-holes and features around a part in one setup
- 5-axis milling: complex surfaces and undercuts in a single clamping
- Prototype and production milling: same machines from first part to thousandth
Typical parts: housings, brackets, manifolds, fixtures, heat sinks and enclosures.
CNC turning services in China
CNC turning gives round parts smooth surfaces and consistent diameters, with good repeatability across large batches. We turn aluminum, stainless steel, titanium, brass and engineering plastics.
- Shafts, pins and spindles
- Bushings and sleeves
- Connectors and fittings
- Threaded parts
- Custom round components to your drawing
Parts that also need flats, cross-holes or milled features can be finished with live tooling.
Why buyers choose Superapid
Direct from the factory. No trading company or marketplace between you and the machine.
Engineer review of every file. We check each model and send DFM feedback before cutting.
Precision you can specify. Standard ±0.05 mm, precision ±0.02 mm, and ±0.01 mm on critical features where geometry allows.
Prototype to production in one place. Orders from 1 to 10,000+ parts on the same machines, by the same team.
Direct communication. Talk to an engineer by email or WhatsApp, in English.
Confidential by default. NDA on request; your files are used only to quote and make your parts.
Industries we serve
Automotive
Prototypes, fixtures and low-volume production parts for testing and assembly.
Medical
Stainless steel and plastic components, surgical tool prototypes and device housings.
Electronics
Enclosures, heat sinks, connectors and mounting parts.
Robotics and automation
Precision gears, shafts, end-effectors and frames.
Consumer products
Design prototypes and small-batch parts that look and fit like the final product.
CNC machining tolerances
We hold ±0.05 mm as standard and can reach ±0.01 mm on critical features, depending on geometry and material.
| Level | Tolerance | Best for |
|---|---|---|
| Standard | ±0.05 mm | General features and non-critical fits |
| Precision | ±0.02 mm | Mating parts, bearing seats, sealing faces |
| High precision | ±0.01 mm | Critical features, on request and subject to review |
Mark critical dimensions on your drawing. Tighter tolerances add machining and inspection time, so we will tell you which features drive cost.
From prototype to production
Repeatable runs from 10 to 10,000+ parts, with first-piece approval and in-process checks so part 1,000 matches part 1. Because the process is proven at prototype stage, scaling up does not mean starting over.
Materials and surface finishes
We machine a wide range of metals and plastics, and finish parts for appearance, corrosion resistance and wear.
| Category | Options |
|---|---|
| Aluminum | 6061, 7075, 5052 |
| Stainless steel | 304, 316, 17-4 PH |
| Other metals | Carbon steel, tool steel, brass, copper, bronze, titanium, magnesium, zinc |
| Plastics | ABS, POM (Delrin), nylon, HDPE, PP, PC, PMMA (acrylic), PEEK, PTFE |
| Finishes | As-machined, bead blasting, sandblasting, brushing, polishing, anodizing (Type II and Type III), black oxide, powder coating, painting |

How it works
1. Send your files. Upload a STEP or IGES model, plus a PDF drawing if you have tolerances, threads or finishes to specify.
2. Get your quote and DFM feedback. An engineer reviews the design and replies within 24 hours with price, lead time and any manufacturability suggestions.
3. We machine and inspect. Your parts are cut, finished and checked against your drawing.
4. Delivered worldwide. Parts are packed for transit and shipped by express courier or freight to your door.
Frequently asked questions
How fast can I get a CNC machining quote?
Most quotes are returned within 24 hours. Upload a STEP or IGES model with material, quantity and finish for the fastest reply.
Is there a minimum order quantity?
No minimum for prototypes. Production runs typically range from 10 to 10,000+ parts.
What are your lead times?
Prototypes typically ship in 3 to 7 days. Production orders typically take 2 to 4 weeks depending on quantity, material and finish.
What tolerances can you hold?
Standard ±0.05 mm, precision ±0.02 mm, and ±0.01 mm on critical features where geometry and material allow.
Which file formats do you accept?
STEP, STP, IGES, SLDPRT, STL and DXF. Add a PDF drawing for threads, finishes or GD&T.
Is my design kept confidential?
Yes. NDA on request. Your designs are used only to quote and manufacture your parts.
Do you provide inspection reports?
Yes — dimensional reports, first-article reports and material certificates on request.
Is CNC machining in China high quality?
Quality depends on the supplier. We are a direct factory with inspection reports, a quality guarantee, and re-make or refund policy.
