Yuhuan CNC (002903) is China's listed specialist in precision grinding, lapping and polishing machines — the finishing layer of hard-brittle and appearance parts (glass, sapphire, ceramics, SiC, metals) for 3C, auto, aerospace and semiconductors.
- Real strengths: A niche leader in grinding/polishing with products qualified into the Apple supply chain (via Lens Technology, Foxconn, BYD Electronics, Luxshare); 287 patents + 95 software copyrights; two machines入选 the MIIT "industrial mother-machine innovation" shortlist (2026); grinding/polishing revenue +35.4% YoY even as total revenue fell.
- Real limitations (audited): It swung to a loss in 2025 — revenue RMB 410.5M (-13.1%), net profit -RMB 19.6M (vs +RMB 13.3M in 2024), deducted profit -RMB 33.3M; gross margin 29.6% (-4.2 ppt); Q1 2026 stayed loss-making. It also has no self-developed CNC controller (machines use imported or domestic systems, with in-house secondary development only).
- One line: The precision-finishing specialist of Chinese machine tools — deep in grinding/polishing IP, but a cyclical trough and controller-dependent, so it complements rather than competes with Gree's larger machining-center + robot business.

2 · Core Strengths
① Precision-grinding finishing niche with supply-chain certification
Yuhuan's grinding/polishing machines cut glass, sapphire, ceramics and SiC for 3C appearance parts. It has served the Apple chain since the iPhone 4 era, supplying polishing/grinding for iPhone 17 appearance materials via partners like Lens Technology, Foxconn, BYD Electronics and Luxshare — a certification barrier that is hard for new entrants to replicate.
② Grinding & polishing revenue grew +35% while total fell
In 2025, CNC grinding/polishing machines reached RMB 163M (+35.4% YoY, 39.8% of revenue); broaching machines RMB 64.5M (+70.2%). The core finishing line is still expanding even as the broader business contracted — a sign of durable niche demand.
③ Thick IP & policy recognition
287 patents + 95 software copyrights; two machines (YHDM580H double-face grinder, YHMGK1720 multi-function cylindrical grinder) were named to the MIIT 2026 industrial-mother-machine innovation shortlist. A "Hunan advanced-manufacturing揭榜挂帅" project was also awarded in 2026.
④ Cross-track reuse into auto / aerospace / semiconductors / robots
Grinding/polishing process know-how transfers to SiC wafer thinning, auto brake discs (carbon-ceramic), bearing rings and humanoid-robot joint / harmonic-reducer parts (broaching machines already delivered to planetary-reducer makers). Auto-parts revenue hit ~24.5% of sales.
3 · Objective Limitations (honest)
① Swung to a loss in 2025, Q1 2026 still negative
Net profit -RMB 19.6M (2024: +RMB 13.3M); deducted -RMB 33.3M. Q1 2026: revenue RMB 103M (-18.1%), net -RMB 8.65M. Drivers: weak 3C capex, gross-margin compression, and a ~70% drop in lower-margin intelligent-equipment revenue.
② Heavy Apple / 3C dependence
Consumer electronics was 49.99% of 2025 revenue. The company itself warns order visibility from this segment is "extremely uncertain" — a single weak iPhone cycle can swing the whole P&L (its stock once hit limit-down on an Apple-price rumor in June 2026).
③ No self-developed CNC controller
Unlike KEDE or Gree, Yuhuan does not sell its own CNC system. Per investor disclosures, machines take imported or domestic systems and the in-house lab only does secondary development. This caps its "full-stack autonomy" story and ties part of its margin to external controller cost.
4 · 2026 Tailwinds — Why Buyers Should Watch
- 3D-glass & titanium upgrade cycle: The 2026–2027 Apple process upgrade (3D curved glass, titanium mid-frames) is expanding grinding/polishing content per device by an estimated 30–80%, with industry estimates of a ~RMB 10B incremental market — Yuhuan is a direct beneficiary.
- Semiconductor substrate thinning: YHDM/YHMGK series handle SiC, sapphire and GaN wafers — a fast-growing domestic-substitution track.
- Humanoid-robot parts: Broaching machines for planetary-reducer components and grinding for harmonic-reducer housings ride the robotics demand pull.
- "十五五" opening + policy tailwind: Management cites industrial-mother-machine policy dividends and emerging-track (aerospace, semiconductors, new materials, robotics) demand as 2026 focus areas.
5 · Competitive Positioning
| Versus | Yuhuan's edge | Where Yuhuan lags |
|---|---|---|
| KEDE (科德) | Deeper in grinding/polishing finishing, Apple-chain certification | KEDE has proprietary five-axis GNC; Yuhuan has none |
| Haitian (海天) | Finishing precision & hard-brittle materials | Haitian is volume gantry/VMC at RMB 3.4B scale; Yuhuan is 1/8 the size |
| Neway (纽威) | Niche grinding IP vs Neway's broad lathe/VMC range | Neway larger (RMB 2.9B), broader export; Yuhuan export thin |
| Jingdiao (精雕) | Larger, listed, audited; broader grinding+broaching | Jingdiao has full in-house stack (controller+spindle+CAM); Yuhuan does not |
| Gree CNC | Finishing-layer specialist (complementary) | Gree owns larger five-axis centers + robot package + proprietary GNC |
6 · Overseas Reality
Yuhuan operates Yuhuan International (Singapore) and the InnoLeap subsidiary for overseas markets, but export revenue is not broken out in the annual report and is modest versus Neway or Haitian. Its overseas pitch is finishing precision for 3C/semiconductor/auto parts rather than volume commodity machines. Overseas buyers evaluating Yuhuan should request direct references and lead times — the public filings do not quantify export scale.
7 · This Week's Gree CNC Angle
Yuhuan = the finishing layer Gree does not own
Gree's CNC business centers on larger metal-cutting five-axis machining centers plus a machine+robot package — rigid machines for structural and precision metal parts. Yuhuan owns the downstream finishing niche: grinding, lapping and polishing of hard-brittle and appearance parts. For an overseas buyer building a full process chain, the two are complementary: Gree for the cut, Yuhuan for the finish. Gree's differentiator remains its proprietary GNC controller and robot integration — areas where Yuhuan is deliberately absent.
8 · Data Credibility Rating
| Claim | Rating | Why |
|---|---|---|
| 2025 revenue / net profit / gross margin / assets | High | Audited annual report (Tianjian CPA), cninfo filings |
| Apple-chain qualification, Lens/Foxconn/BYD/Luxshare as customers | Medium | Company investor disclosures + media; relationship depth not contractually verified |
| 287 patents, MIIT 2026 innovation shortlist | High | Company filings + MIIT public list |
| No self-developed CNC controller (uses imported/domestic) | High | Direct investor-disclosure wording |
| Overseas revenue scale | Low | Not disclosed in filings; treat export claims cautiously |
9 · Guidance by Use Case
- Overseas 3C / glass-ceramic component maker: Yuhuan is worth a look for grinding/polishing of hard-brittle parts — but verify Apple-program references and lead times directly.
- Auto / aerospace / semiconductor finishing: Double-face grinders and SiC-thinning machines are relevant; request demo parts and accuracy-retention data.
- Robot-parts supplier: Broaching machines for reducer components are a fit; confirm delivery track record.
- Investor: 2025 is a cyclical trough (loss-making, 3C-dependent). The grind/polish recovery and policy tailwind are the upside; concentration risk is the downside. Not investment advice.

Frequently Asked Questions
What is Yuhuan CNC best known for?
Precision grinding, lapping and polishing machines — especially CNC double-face grinders and polishing centers for hard-brittle materials (glass, sapphire, ceramics, SiC, metals). Its grinding/polishing machines serve 3C electronics appearance parts and are qualified into the Apple supply chain via partners like Lens Technology and Foxconn.
Does Yuhuan CNC make its own CNC controller?
No. Per the company's own investor disclosures, its machines can be equipped with either imported or domestic CNC systems, and it runs an "intelligent control technology joint lab" that does secondary development of mid-to-high-end CNC systems — but it does not sell its own controller brand. This is a key difference versus KEDE or Gree, which develop proprietary CNC systems (GNC).
Is Yuhuan CNC profitable?
It swung to a loss in 2025. Audited 2025 revenue was RMB 410.5M (-13.13% YoY); net profit attributable to shareholders was -RMB 19.6M (vs +RMB 13.3M in 2024); deducted net profit was -RMB 33.3M. Q1 2026 remained loss-making. The swing is tied to weak 3C capex and falling gross margin (29.64%, -4.24 ppt). Treat as a cyclical trough, not a structural collapse.
How does Yuhuan compare with Gree's CNC business?
Yuhuan owns the precision grinding/lapping/polishing niche for hard-brittle and appearance parts (3C, semiconductors, auto), while Gree targets larger metal-cutting five-axis machining centers plus a machine+robot package. They are complementary, not head-to-head — Yuhuan is the finishing-precision specialist, Gree the rigid-machine-plus-automation systems player.
