Adopting a unified fleet of high‑end precision equipment across the whole factory, we provide custom manufacturing for all types of metal turning products. We focus on solving tough machining challenges for precision components that demand high accuracy, high concentricity, low circular run‑out, excellent stability and sophisticated irregular geometries.
Dedicated to high‑end supply chains, we deliver stable, micron‑level, mass‑producible and highly‑consistent precision machining solutions for domestic and international brand customers.
- Full individual inspection, separate packaging prior to shipment for greatly enhanced product pass rate.
- Runout / concentricity controlled to 0.003–0.01 mm
- One-setup multi-axis machining — zero re-fixturing error

One factory. One machine standard.
Zero compromise on accuracy.
Located in Chang’an (Dongguan, Guangdong), nationally celebrated as a prominent town for high‑end machinery, hardware & moulds and a hundred‑billion‑dollar‑scale precision intelligent‑manufacturing hub, Giant Precision devotes itself to custom production of high‑end turn‑mill composite precision components. Backed by a mature high‑end supply‑chain ecosystem and profound manufacturing legacy, our factory adopts a complete lineup of Japan‑imported premium precision equipment with unified plant‑wide accuracy criteria. It effectively removes quality gaps between prototype samples and mass‑run output. Thanks to our outstanding stability in volume manufacturing, we serve as a reliable core precision‑processing supplier for mid‑to‑high‑end brands worldwide.
We do not run general-purpose CNC roughing, and we do not mix machine brands. That single equipment standard keeps rigidity, vibration resistance and repeatability uniform across every part we ship — which is exactly why we can take on the jobs most suppliers turn down: ultra-slender shafts, thin-wall components, deep micro-holes, precision trapezoidal threads, eccentric structures and multi-step precision fits.
- Original NOMURA 1.0 / 16 / 20 / 25 full machine coverage
- Walter (Germany) original tooling system for stable surface finish
- Serving new energy, automotive, automation, connectors & medical chains
- OEM / ODM precision matching for overseas brand customers
- Engineering-led communication — one-to-one technical support
Six reasons engineers keep coming back
We are not the cheapest shop in Dongguan, and that is deliberate. We compete on accuracy, consistency and the ability to hold tolerance when volume ramps up.
All-NOMURA Equipment Fleet
No mixed brands and no roughing-only machines. One Japanese precision benchmark across the whole plant.
Micron-Level Accuracy
Runout, concentricity and straightness controlled within 0.003–0.01 mm on critical features.
One-Setup Multi-Axis Machining
Multi-axis simultaneous machining completes complex parts in a single clamping — zero re-fixturing error.
Difficult Parts Welcome
Ultra-slender shafts, thin-wall parts, micro deep holes, sealing grooves and eccentric structures.
Walter Premium Tooling
Original Walter tooling delivers fine tool marks, controllable finish and long-term dimensional stability.
Export-Ready Documentation
Material certificates, full inspection reports, PPAP and IMDS support for overseas programmes.

We adopt a complete system of high‑end equipment imported from Japan, featuring consistent precision and stable mass‑production performance, making us your preferred supplier for high‑end components.
From micro parts to long shafts, every machine shares the same Japanese accuracy baseline. That is how we guarantee sample accuracy = batch accuracy.
NOMURA 1.0
Ultra-Micro Precision
Micro shafts, micro holes, micro pins and micro irregular parts. Solves ultra-small structures, thin edges, fine threads and micro grooves that standard machines cannot hold.
NOMURA 16
High-Precision Compact
Small-diameter complex mill-turn parts, precision terminals, small shaft cores and connector assemblies. High speed, near-zero vibration, excellent surface finish.
NOMURA 20
Main Production Model
Our core volume platform for small-to-medium precision shafts, valve parts, pins, motor shafts and sensor structures — balancing accuracy, stability and throughput.
NOMURA 25
6-Axis Flagship
NN25UB / 25YB / NN-10EX2K six-axis models for long shafts, large diameters, high runout and high coaxiality requirements, multi-process composite parts and safety-critical components.
