Who this event is for

New this edition

• 1

  —

  Recent editions have put embedded AI in front of visitors, typically through machine-control, monitoring and inspection demonstrations rather than conference talk. For a bar-turning shop the practical takeaway is in-machine inference for tool wear, chatter and defect detection.

• 2

  —

  The show has built out technical content on polishing and surface finishing competences, aimed at watch and medtech buyers who need edge quality and roughness controlled on microcomponents rather than just dimensional tolerance.

Frequently asked

Glossary

1

Microtechnology

The engineering discipline behind millimetre- and micrometre-scale components and the production equipment that makes them, the technical core of SIAMS.

2

Bar turning (décolletage)

High-volume turning of small precision parts from metal bar stock, historically on cam-controlled automatics and today largely on CNC lathes; the Jura's signature industry and the largest exhibitor group at the fair.

3

Swiss-type lathe (sliding-headstock automatic)

A lathe in which the bar is pushed through a rotating guide bush so the cut happens right at the support point. That geometry lets slender watch and medical parts be turned without deflection and is the machine type most often demonstrated live at SIAMS.

4

Guide bush

The hardened bushing that supports the bar immediately before the cutting tool on a sliding-head lathe. Its clearance and condition drive roundness and surface quality on long, thin parts.

5

Lights-out production

Unattended or lightly attended running, usually overnight, made possible by bar feeders, chip conveyors, tool-life monitoring and in-machine gauging. A recurring theme for job shops buying automation at the show.

6

In-process probing and measurement

Measurement taken on the machine between cutting steps to correct tool offsets and confirm tolerance before the part leaves the spindle, instead of relying only on a metrology lab afterwards.

7

Surface finishing and deburring

Polishing, drag finishing, vibratory and tribofinishing processes that set the final roughness and edge quality of microcomponents; SIAMS has published technical content on polishing competences for exactly this buyer group.

8

Clamping and tooling systems

Collets, guide bushes, tool holders, quick-change systems and micro-tools. Small differences in rigidity and repeatability here show up directly in part tolerance and cycle time on a bar-turning machine.

9

Medical-grade machining

Production of implants, instruments and device components under an ISO 13485 quality regime, with material traceability, validated processes and documented inspection - a growing customer segment for Jura subcontractors.

10

Jura arc (Watch Valley)

The precision-industry corridor from Geneva through Neuchâtel, La Chaux-de-Fonds, Biel and Delémont to Moutier, where watch, medtech, connector and aerospace suppliers cluster within a short drive of the fair.

11

Embedded AI

Inference running inside a machine control, camera or inspection unit rather than in the cloud. SIAMS has presented embedded AI to fair visitors as a show innovation, typically in machine-monitoring and defect-detection demonstrations.
