China CNC Machining Supplier for Precision OEM Parts
220 CNC machines · 70 Swiss-type lathes · 5 million parts per month · 50+ export countries
CHX Metal is a China CNC machining supplier in Shenzhen: 220 CNC machines, 70 Swiss-type lathes, ISO 9001, ±0.005 mm, 5M PCS/month, quotes in 24 h. Engineering teams review drawings and return manufacturability feedback within 24 hours.
CHX Metal (Shenzhen Changhexin Precision Hardware Co., Ltd.) has produced precision CNC parts in Shenzhen since 2013. We run 220 CNC machines — 100 machining centers, 50 CNC lathes and 70 Swiss-type lathes — and ship to more than 50 countries, with a monthly capacity of up to 5 million pieces.
Why source precision CNC parts from China
China’s Pearl River Delta combines a dense supply chain, experienced machinists and modern machine tools, which is why so many Western OEMs source precision components here. A well-run factory cuts unit cost without giving up tolerance: our plant holds ±0.005 mm on critical features and verifies them on a CMM before shipment.
The real risk is picking the wrong supplier. The sections below explain what to check, and what our own factory can deliver.
What CHX Metal can machine
- 220 CNC machines: 100 machining centers, 50 CNC lathes, 70 Swiss-type lathes
- Tolerance ±0.005mm, verified on a CMM
- Materials: aluminium 6061/7075, stainless 303/304/316, free-cutting steel, brass C3604, titanium, PEEK
- Diameter range: bar Ø1–20 mm (Swiss-type) up to larger turned and milled parts
- In-house finishing: anodizing, zinc/nickel plating, passivation, black oxide, laser marking
- Capacity: 5,000,000 PCS/month · 5,000 m² plant · 100+ employees
Because turning, milling, 5-axis and finishing all happen under one roof, you deal with one accountable partner instead of a chain of subcontractors.
How to vet a China CNC machining supplier
- Certifications: verify ISO 9001 at minimum; check the certificate number and validity on the issuing body’s site
- Machine list: ask for the actual machine park — brand, axis count and quantity — not a capability statement
- Sample reports: request a real FAI and CMM report from a previous job
- NDA: a serious supplier signs a mutual NDA before receiving your drawings
- Communication: response time and DFM feedback quality reveal how the project will run
- References: ask which countries and industries they already export to
Order process and lead times
Send your drawing (DXF/DWG/STEP/IGES) or sample with material, quantity and finish. Our engineers review manufacturability and return a quotation with DFM feedback within 24 hours. Prototypes ship in 3–7 days, production batches in 7–15 days, and surface treatment adds 5–10 days. Volume programs are scheduled against a confirmed rolling forecast.
Quality documents and traceability
Every order ships with in-process inspection records. Critical dimensions are verified against your drawing on first article, at batch start and at final release. EN 10204 3.1 material certificates and full dimensional reports come as standard; PPAP and FAIR documentation are available on request for automotive and industrial programs.
Frequently Asked Questions
What is your minimum order quantity? There is no strict MOQ — we take single prototypes through to volume production. Unit price falls as quantity rises, so tell us your annual volume and we will quote the most economical batch size.
How fast will I get a quotation? Our engineers review your drawing and return a quotation with DFM feedback within 24 hours on working days.
What tolerances can you hold? ±0.005 mm as standard and ±0.005 mm on precision features, verified on a CMM and reported on the inspection report that accompanies each shipment.
Which materials do you machine? Aluminium 6061/7075, stainless 303/304/316, free-cutting and carbon steel, brass C3604, titanium TC4 and engineering plastics such as PEEK. Other grades are available on request.
How do you ship to my country? We export to 50+ countries by air and sea through vetted forwarders, with commercial invoice, packing list and certificates prepared for customs. DDP and DAP terms are available.
