CNC Machining Supplier for US Buyers

CHX Metal (Shenzhen Changhexin Precision Hardware Co., Ltd.) manufactures custom CNC machined and Swiss-type turned parts for US companies — from prototype to volume production — with inch or metric drawings, English-speaking sales and door-to-door shipping to the United States.

Why US companies source CNC parts from CHX Metal

US buyers work with CHX Metal for one reason: verifiable capability at a competitive landed cost. We run 220 machines in-house — 100 CNC machining centres, 50 CNC lathes and 70 Swiss-type sliding-headstock lathes (Tsugami) — plus 8 in-house inspection instruments including a CMM (Leyden), against a monthly capacity of up to 5,000,000 pcs.

Every order is quoted by an English-speaking engineer who works to your drawing revision, not to a catalogue part. Prototypes ship in 3–7 days; production batches in 7–15 days.

Inch and metric drawings, ANSI/ASME Y14.5 GD&T

We accept both imperial and metric drawings. Tolerances and GD&T are read to ANSI/ASME Y14.5 for US prints and to ISO 1101 for metric prints; UNC/UNF and NPT threads are standard. Standard tolerance is ±0.005 mm (±0.0002 in), with ±0.005 mm on critical features, verified by CMM.

Bring us a 2D PDF, a 3D STEP/IGES model or a physical sample — DFM feedback is returned with the quote.

Tariffs, HS codes and landed cost to the USA

We quote FOB Shenzhen, CIF or DDP to your US address so the landed cost is visible up front. HS classification, commercial invoice and packing list are prepared for each shipment, and we provide the documentation your customs broker needs. Where a tariff line applies (for example under Section 301), we state it clearly on the quote rather than hiding it in freight.

Air express (DHL / FedEx / UPS) reaches most US cities in 5–8 days; sea freight runs 25–35 days for larger batches.

Lead times and communication across time zones

Quotes are returned within 12 working hours. Our sales engineers overlap with US business hours, so a question asked in Chicago or Los Angeles is answered the same working day.

Prototypes 3–7 days · production batches 7–15 days · surface treatment adds 5–10 days. Rush programmes can be scheduled on request.

Quality documents US customers expect

Each batch can ship with a FAI report, a CMM dimensional report, EN 10204 3.1 material certificates and full batch traceability. PPAP-style packages and first-article inspection are available on request for automotive and industrial programmes.

CHX Metal holds ISO 9001:2015 (certificate NOA198428, valid to 2028-06-30) and ISO 14001:2015 (NOA2100184, valid to 2027-01-04), issued by NOA, an IAF Multilateral Recognition Arrangement member. IATF 16949 and ISO 13485 are being implemented and are not claimed as held.

Materials and finishes popular with US buyers

Aluminium 6061-T6 and 7075, stainless 303/304/316, free-cutting and carbon steel, brass C3604, titanium TC4, and engineering plastics including POM/Delrin and PEEK.

In-house finishing: anodizing, zinc and nickel plating, passivation, black oxide, powder coating and laser marking — no third-party hand-off for the common finishes.

Frequently asked questions

Do you ship CNC machined parts to the United States?

Yes. We ship to all US states by air express (5–8 days door to door) or sea freight (25–35 days) and quote FOB, CIF or DDP so you see the landed cost.

Can you work to inch drawings and ANSI/ASME standards?

Yes. We read imperial prints to ANSI/ASME Y14.5 GD&T, cut UNC/UNF and NPT threads, and hold ±0.005 mm (±0.0002 in) standard tolerance, verified by CMM.

How do you handle US tariffs?

We quote FOB, CIF or DDP. HS codes and commercial documents are prepared for your customs broker, and any applicable tariff line is stated on the quote rather than buried in freight.

What is the lead time for a US order?

Prototypes 3–7 days, production batches 7–15 days, plus 5–10 days for surface treatment. Quotes are returned within 12 working hours.

What is the minimum order quantity?

There is no strict MOQ — we run a single prototype through to volume production, so you can validate the part before committing to a batch.

What quality documents do you provide?

FAI report, CMM dimensional report, EN 10204 3.1 material certificates and batch traceability; PPAP-style packages on request. ISO 9001:2015 and ISO 14001:2015 are certified.
