Advisory before cutting
Every RFQ comes back with a number and notes on the tolerances that actually drive cost — not a request for more information. Where a feature is expensive for no functional reason, we say so.

How we work
One process, run properly — then documented.
We are a Swiss-only shop floor. That focus decides how we advise, how we route work, and what leaves the building with every shipment.
Routed by tolerance class
14 Japanese-built machines (Citizen Cincom, Tsugami) take the tight-tolerance and complex work; 5 Chinese-built machines (TODAYCNC, SOWIN) run volume. Work is allocated by tolerance class, not by which machine happens to be free.
Documentation as standard
Dimensional report, ballooned first-article inspection, EN 10204 3.1 material certificate, roughness records and RoHS / REACH declaration ship with every order — not on request.

Nineteen sliding-headstock lathes
Every machine carries a sub-spindle and driven tooling, so front and back working are completed in one cycle. The fleet covers Ø3.0–32 mm bar; 19 of 19 machines handle ≤Ø20 mm work.
| Brand | Model | Qty | Max bar Ø | Control |
|---|---|---|---|---|
| Citizen Cincom | L20E-2M10 | 6 | Ø20 mm (Ø25 option) | 6-axis |
| Citizen Cincom | L32 | 2 | Ø32 mm | 5-axis |
| Tsugami | B0205 | 6 | Ø20 mm | 5-axis |
| TODAYCNC | TC32 series | 2 | Ø32 mm | 5-axis |
| SOWIN | SZ-20 series | 3 | Ø25 mm | 5–6-axis |

Inside the shop
The floor, photographed this week
Real machines, real coolant, real parts in the green trays. This is the shop that will run your order.
02 — Capability envelope
Full envelope →
What the shop can hold, and on what basis
The ±0.005 mm figure is a diameter capability: turned diameters on parts ≤ Ø32 mm from ground or peeled bar (h6–h9), on a temperature-controlled floor at 20 ± 2 °C with chilled coolant, verified by in-process SPC at Cpk ≥ 1.33 and confirmed on the CMM. Positional, concentricity, thread and deep-bore features are quoted against the drawing, feature by feature.
03 — Metrology
Inspection we do not subcontract
A patrol inspector and a CMM inspector cover every shift. Patrol inspection runs on a two-hour cycle across all 19 machines with recorded results; first-piece and last-piece of every batch are verified in the metrology room. Night shift carries the same cover as day shift — no production runs without inspection.
- Hexagon CMM — Explorer Scan 686, scanning type, commissioned 2026, with Ø0.3 / Ø0.5 mm ruby styli
- Wilson MMD-100 contour / form instrument — small radii, chamfers, groove profiles
- Mitutoyo SJ-210 roughness tester — Ra / Rz / Rmax
- Measurement uncertainty stated on every first-article report and applied as a guard band before any feature is accepted against a ±0.005 mm limit
First-article reports in English
Dimension by dimension, ballooned and indexed to your drawing numbers.
Traceable calibration
CNAS-accredited, traceable to national standards. Certificates on file with expiry dates.
Heat to lot traceability
Mill test certificates to EN 10204 3.1 with every shipment, bar heat number to finished lot.
Records retained per lot
Inspection records kept against the lot number and available on request.
04 — Why customers stay
Three reasons, stated plainly
Metrology you can audit
CMM, contour / form, roughness and hand-gauge metrology are all in-house. We do not subcontract inspection, so the report matches the part.
Swiss-only shop floor
19 sliding-headstock lathes and nothing else. Small diameter, high length-to-diameter, multi-operation parts are our only business.
