About GuKen Precision
A machining factory built around one idea: the parts other shops avoid are the parts we mastered.
Who we are
GuKen Precision (Dongguan Guken Technology Co., Ltd.) is a precision machining factory in Dongguan, Guangdong — the heart of China’s manufacturing supply chain. We manufacture high-precision CNC machined parts, complete assemblies and OEM/ODM solutions for customers in Europe, North America, the Middle East and Southeast Asia — across communications, machinery, medical, automotive, optics and automation equipment.
Behind the parts: 60+ imported machines — CNC machining centers from Okuma, Makino and Brother, a Mazak 5-axis, precision CNC lathes, Sodick / GF+ / Seibu slow wire EDM, and ZEISS coordinate measuring machines for final inspection. A team of 20+ process engineers plans every job through IQC (incoming), IPQC (in-process) and FQC (final) control gates.
Our name says what we believe: “Gu” for the craftsman’s patience of Japanese precision culture; “Ken” after Kennametal, the American standard for cutting-tool excellence. Japanese craftsmanship, American engineering standards — applied to every order, whether it’s one part or ten thousand.
One-stop finishing & assembly
Parts leave our floor ready for yours — no juggling five vendors.
- Complete assemblies & OEM/ODM — from single precision parts to sub-assemblies delivered ready for your production line
- Surface treatment, coordinated in-house — anodizing (standard & hard), electroplating, electrophoresis, powder coating, polishing, brushing, knurling, heat treatment, silk-screen printing, laser marking
- Full material range from stock — aluminum 2017–7075, brass & copper alloys incl. beryllium copper, SUS303/304/316/17-4PH stainless, Ti-6Al-4V, PEEK / PEI / PPS / POM, plus our specialty: Invar 36 & Kovar
- Any drawing format — STEP, IGES, SolidWorks, Pro/E, DWG, DXF, PDF
What makes us different
- We specialize in difficult-to-machine alloys — Invar 36, Kovar, titanium and engineering plastics, with process control most general shops don’t invest in
- Real production capacity — 60+ CNC machines running 24 hours, so your urgent orders are a scheduling problem, not a promise problem
- Engineers, not brokers — the person answering your RFQ holds the same drawing you hold, and has walked the process route on the shop floor
- Export experience — familiar with ISO 2768, DIN 7168 and customer-specific standards; documentation English-ready by default
- Honest tolerance claims — we quote what we can measure on our ZEISS CMM. If a feature is outside our verified capability, we tell you before you place the order

Our quality promise
Three commitments we put in writing on every order:
1 · Full inspection, every order
FAI dimensional report from our ZEISS CMM ships with every lot. You verify us with data, not with promises.
2 · One-hour response
Business-hour RFQs get an engineer’s reply within one hour. Quotations typically within 24 hours.
3 · Straight answers
If a tolerance, deadline or material requirement doesn’t make sense, you’ll hear it from us before you commit — not after the parts arrive.
