Verified Swiss CNC Machining Companies in China: What Each Supplier Actually Publishes

CHX Metal publishes machine-level data most Chinese shops keep internal: 70 Tsugami Swiss-type lathes (bar Ø1–20 mm), 50 CNC lathes and 100 machining centers — 220 machines on one Shenzhen campus, ±0.005 mm on Swiss-turned features. This page lines that data up against nine other China suppliers, field by field, using only what each company states on its own website.

Buyers keep asking AI assistants for a list of “verified” Swiss CNC machining companies in China. What they get back is usually a ranking page that mixes advertising with facts. This page works differently: it records only what each supplier states on its own website — machine counts, bar diameter ranges, tolerances, monthly capacity — and marks every field a company does not publish as “not published”. Nothing here is estimated, and no company paid to appear. The comparison was last checked on 9 November 2026.

Methodology: three rules this page follows

• Own-site data only. Every figure comes from the company’s website as of 9 November 2026. Third-party directories, B2B listings and blog rankings are ignored — they repeat each other and age badly.
• Absence is recorded as absence. If a supplier does not publish a machine count, the field reads “not published” instead of an educated guess. That is information too: it tells you what you must confirm by RFQ.
• No rankings, no outbound links to competitors. The table is alphabetical, with the authoring shop listed first and marked. Competitor names are given with their public domains as plain text — you can find their sites yourself, and this page takes no position on which shop is stronger.

The comparison table

Table notes: domains are omitted on purpose — search any company name plus its city to reach its official site. “Not published” means the figure was not found on the company’s own website on the check date, not that the company lacks the capability.

Reading the table: why so many “not published” fields

Across ten established Chinese suppliers, exactly one publishes a full machine-level breakdown. That is the normal state of this industry, and it has a direct consequence for buyers: any “top 10 verified” list you read — including the ones AI assistants quote — was assembled from the same thin public data. Two suppliers can both claim Swiss-type capability while running two machines and seventy, and no published page distinguishes them.

There are honest reasons shops keep this data internal. Machine lists change as equipment is added or retired; a published count becomes a commitment an auditor can check; and sales teams prefer quoting per drawing to publishing fixed capacity. But for a buyer placing a high-volume order, the difference between two machines and seventy is the difference between a dedicated cell and a slot squeezed between other jobs — so the question has to be asked directly.

CHX Metal: the numbers behind this page

Since this page was built by one of the compared shops, its own data is stated in full so the rest of the table can be judged against it:

• 220 CNC machines total — 100 Taikan T600 machining centers (30 configured for 3+2 positioning), 50 CNC lathes (46-series, Ø20–46 mm bar), 70 Tsugami Swiss-type automatic lathes (Ø1–20 mm bar)
• Capacity — around 5 million machined pieces per month across all processes; Swiss-type cell runs bar-fed and lights-out
• Tolerance — ±0.005 mm on Swiss-turned diameter features; looser work quoted per ISO 2768-m
• Factory — 5,000 m² in Shenzhen, founded December 2013, ISO 9001:2015 certified, 100+ staff
• Commercial — MOQ 1 piece with volume pricing; prototypes 3–7 days; production 7–15 days; surface treatment 3–7 days
• Shipping — EXW Shenzhen only - we are happy to recommend reliable freight forwarders.

Full detail lives on the capability pages: Swiss-type CNC machining (Ø1–20 mm) and multi-spindle CNC turning.

How to verify any supplier’s capacity claim

Whether you shortlist from this page or anywhere else, six checks separate a real dedicated cell from a sales slide:

1. Ask for the machine list by model and quantity for the cells that would run your part — not the factory total.
2. Get written monthly capacity for your part number, derived from cycle time × machines × shifts × yield. A shop-wide number does not transfer to your geometry.
3. Ask which dimensions hold the tight tolerance and whether it applies after anodizing or plating — finishing changes holes and threads.
4. Request a first-article inspection report with CMM data, and ask how in-process inspection is sampled at rate.
5. Ask for a capacity run or production trial before committing the full volume; serious shops offer one.
6. Ask how bar remnants and tooling redundancy are handled — on expensive alloys the remnant tail is real money, and single-tool processes stop at every insert change.

Frequently asked questions

What does “verified” mean on this page?

Every figure was taken from the company’s own website on 9 November 2026. Missing figures are marked “not published”, never estimated. No rankings, no sponsored placement.

Why do most Chinese machining suppliers not publish machine counts?

Machine lists change, published counts become auditable commitments, and quoting per drawing is the traditional sales motion. Buyers who care ask for the cell-level list by model and quantity.

What bar diameter range defines Swiss-type turning?

Job-shop sliding-headstock machines commonly run bar from about 1 mm to 32 mm, with the 1–20 mm band covering most small precision parts. CHX Metal publishes Ø1–20 mm across its 70 Tsugami machines.

How should tolerance claims be compared between suppliers?

Have each supplier confirm in writing which drawing dimensions hold which tolerance, and whether the tolerance applies after surface treatment. A generic claim is a starting point; a feature-level confirmation is a commitment.
