The CNC Machining Company Behind Your Parts
IsoCNC is a CNC machining company based in China, producing custom precision parts for OEMs and product companies in North America and Europe. When you place an order with us, your parts are machined on our own floor, by our own machinists, on equipment we own and maintain — milling, turning, finishing, inspection, and export packing under one roof.
A Factory, Not a Middleman
That matters more than it sounds. With a broker or a platform, your drawing passes through layers before it reaches a spindle — and so does every question about it. With IsoCNC, the engineer who quotes your part talks to the people who machine it. Answers come faster, nothing gets lost between sales and the shop floor, and when a tolerance or a finish needs a judgment call, the person making it can see the machine.
What's on Our Floor
| Capability | Specification |
|---|---|
| CNC milling centers | 20, including 4 five-axis machining centers |
| CNC lathes | 12, live-tooling equipped |
| Production floor | 2,500 m² with dedicated inspection room |
| Inspection equipment | CMM, optical projector, height gauges, bore and thread gauges, surface roughness tester, hardness tester |
| Supporting processes | Wire EDM, surface and cylindrical grinding, honing |
We keep capacity balanced across milling and turning so a mixed order — housings plus shafts, brackets plus fittings — ships as one delivery instead of two.
Beyond milling and turning, we support the processes a complete part needs: heat treatment coordination and a full finishing line covering anodizing, plating, passivation, powder coat, bead blast, and laser marking. One PO covers the part from raw stock to finished, inspected, packed product.
Inspection is part of the floor, not an afterthought: calibrated gauges and dimensional verification for critical dimensions, with records tied to your drawing's balloon numbers. Details are on our quality inspection page.
How We Work with Overseas Customers
Most of our customers never visit the factory — so we make remote sourcing behave like having a shop down the road:
- English-speaking project engineers handle your RFQ, DFM questions, and order status. You get technical answers in writing, not template replies.
- Documented quality. First article inspection reports, dimensional records against your drawing, and material certificates on request.
- Export handled. Export-grade packing, rust protection, and shipping by air or sea with DAP/DDP options. Customs documentation is our job, not yours.
- Reorders without friction. Programs, fixtures, and inspection plans are kept on file. A reorder is a PO, not a new project.
Communication Across Time Zones
We work against North American and European business hours as a matter of routine. RFQs and technical questions sent during your working day are picked up at the start of ours, and a project engineer replies in writing — pricing, lead time, and DFM feedback in one message, not a chain of clarifications. Because answers come from the engineer quoting your part, a question about a datum scheme or a thread callout gets a technical answer, not a forwarded screenshot.
Everything important is documented in writing by default: quote confirmations, drawing revisions, inspection results, and shipping details live in email you can forward to your quality or purchasing team. When a call helps — a design review, a problem on a tight deadline — we schedule it at a workable hour for your time zone, and we send a written summary afterward so nothing depends on memory. For anything urgent, the contact page reaches the same engineers who handle quotes.
Quality Documentation You Can Audit
Every order can ship with a paper trail: first article inspection reports, dimensional reports against the drawing, material certificates, and finish certifications where the process calls for them. If your quality team needs a specific report format, ballooned drawings, or PPAP-style documentation for an automotive program, tell us at RFQ stage and we build it into the inspection plan. An overview of the standards and audit frameworks we work to is on our certifications page.
What We Machine
From single prototypes to repeat production runs: aluminum enclosures, stainless fittings, titanium brackets, steel fixtures, brass and copper components, and engineering plastic parts.
