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)

These are audited facts, not rumors. Yuhuan is in a cyclical trough — we present them plainly so overseas buyers/investors can weigh risk, not to disparage the company.

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.

5 · Competitive Positioning

VersusYuhuan's edgeWhere Yuhuan lags
KEDE (科德)Deeper in grinding/polishing finishing, Apple-chain certificationKEDE has proprietary five-axis GNC; Yuhuan has none
Haitian (海天)Finishing precision & hard-brittle materialsHaitian 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 rangeNeway larger (RMB 2.9B), broader export; Yuhuan export thin
Jingdiao (精雕)Larger, listed, audited; broader grinding+broachingJingdiao has full in-house stack (controller+spindle+CAM); Yuhuan does not
Gree CNCFinishing-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.

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.
