About HongChen CNC
Engineering feedback first, paperwork last.
We exist for the engineers and buyers who care about getting parts right — not for those shopping by spreadsheet. Every project gets a clear DFM answer and a real delivery date, not a marketing number.
Two decades on the shop floor
Milestones worth showing.
- 2006
One milling centre, one engineer.
HongChen Precision opens in a single bay with a three-axis VMC and a promise: every drawing gets a real engineer to read it before any quote goes out.
- 2011
Five-axis arrives.
We add our first five-axis trunnion to handle complex geometry in one setup. Tolerance grades tighten and lead times drop on the parts that used to need three operations.
- 2015
ISO 9001:2015 certification.
An independent audit confirms our quality management system. Documentation moves from a shared folder to a controlled, traceable trail on every shipment.
- 2019
Second workshop, second time zone.
A partner workshop on the other side of the country joins the chain. Capacity roughly doubles, and engineering review stays under one roof so the answer in your inbox is always the same one.
- 2023
In-process inspection on every cell.
CMM and surface-roughness probes are wired into the production cells. First-article and in-process checks happen without slowing the cycle.
- 2026
DFM answers in one business day.
The current team — engineering, production, supply — runs the workflow that ships a real DFM reply and a real delivery date inside one working day for almost every drawing we receive.

- 05
Defence
ITAR-registered projects, ruggedised enclosures, field-serviceable assemblies.
- 06
Consumer hardware
From limited runs to keep-alive spares for products shipped years ago.
Certifications
Documentation, not decorative.
Certificates live on each quote — never on a marketing slide.

Quality without guesswork
Evidence at every critical point.
Quality is not a slide at the end of the pitch. It is built into every cell, every inspection report, and every shipped package.
First-article inspection
Every PO starts with a written FAI report — full dimensional check against the drawing, signed by the engineer who reviewed the part.
In-process CMM
Tight-tolerance features are measured on the machine, not just at the end. Drift gets caught before it costs you a batch.
Surface testing
Roughness and hardness tests available on request, performed in our metrology lab and reported back with the shipment.
Full traceability
Material certificates, FAI reports, and inspection summaries are bundled into a PDF and emailed with every delivery.
Bring a part
Send your file and quality requirements.
Drop a STEP or PDF, tell us the critical tolerances, and we will reply with a fixed quote and a realistic lead time within one business day.
