From bar stock to micron-precise parts.
Tec-Joux masters the processes that define precision in the Jura Arc: automatic Tsugami bar turning, 3/5-axis milling, mill-turn, through to final inspection.
A human-scale SME led by a master of micromachining: one point of contact, unmatched responsiveness.
See our capabilitiesTsugami bar turning
Tsugami machines, known and mastered for years. Tight tolerances on small diameters, medium to large series.
3 & 5-axis milling
Fanuc and KIRA machining centres for complex geometries, plus a 5-axis Tsugami mill-turn centre.
Finishing & quality control
Micron-level inspection: Sylvac comparators (0,0001 mm), Marcel Aubert microscopes, gauge blocks. Every part checked, every series traced.

Frequently asked questions.
Yes. We machine single parts and prototypes from the very first unit, on our 3/5-axis milling centres and lathes.
We mainly machine brass, steel, stainless steel and aluminium. Other materials on request — specify your need in the quote form. (Exact list to be completed.)
They depend on the process, complexity and series. We reply to every quote request with a precise lead time. Indicative lead times by series type are being defined. (To be completed.)
From single parts to tens of thousands of parts per series, depending on the process and machine.
Absolutely. Your files are handled confidentially and used only to prepare your quote and produce your parts.
Yes — it is actually our main entry point. We integrate into your production chain, complementing or relieving your volumes.
