In nanomachining, less is more Published on the octobre 30, 2024 Showcasing precision watchmaking, the EPHJ trade fair welcomes a panoply of supremely talented subcontractors. Among them is Vuichard SAS, a firm from the Haute-Savoie region close to the Franco-Swiss border. It will be an exhibitor at EPHJ once again in 2025, drawing on expertise gleaned from almost 60 years’ experience in extra-high-precision machining to present some real feats of nanomachining. Visitors will be able to examine samples under a high-power magnifying glass, all produced using one-of-a-kind techniques. The company’s beginnings lie in die-sinking electro-discharge machining (EDM) and wire cutting, as illustrated by its fleet of 10 or so micro-erosion machines, using wire with a minimum diameter of 0.03 mm. Holes can be micro-drilled to diameters as small as 0.025 mm in the die-sinking discharge machining workshop. In 5-axis micro-milling, its Matsuura machining centre – with a 60,000-rpm spindle, 0.1-μm travel and cutters that are at least 0.04 mm in diameter – produces work of unrivalled finesse in steel with a hardness of up to 65 HRC. Micromachining makes up another element of this expertise. The relevant technologies have contributed to the creation of an outstanding watch, bringing together micro-erosion machines and machining of silicon crystal. As specialists in the seemingly impossible, ceramic parts manufacturer HARDEX and French subcontractor Vuichard rose to the challenges set by the designer. The products of other challenges recently taken on by Vuichard SAS will be on display at its stand in 2025. Like the company itself, here we have a modestly-sized space which will be showcasing some big innovations on a very small scale! Thanks to the precision of the Matsuura LX-O 5-axis machining centre, precision electrode production allows for die-sinking operations of a quality that would otherwise be impossible to achieve.

Blue Phosphor, the AI magic wand Publié le mai 30, 2024 Quality is a must when it comes to watches and jewellery. At the upcoming EPHJ show, AnotherBrain will showcase how it is using artificial intelligence (AI) to inspect the appearance of items. Share this article Facebook Twitter Youtube Uncompromising quality AnotherBrain – a startup that is home to 40 AI researchers – designed a software platform it calls Blue Phosphor® to enhance and verify the visual quality of manufactured products. At EPHJ 2024, its team will present the two key pillars driving this solution, Vision and Pilot, which support consistent quality by delivering robust and objective inspection capability. Vision draws on its connection to systems that optically assess parts to capture data, which is then compared with the idealised model to check its compliance. AI is contributing to the emergence of a new generation of quality specialists who are relieved of the burden of performing arduous and repetitive tasks. An intuitive heat map allows this application to locate functional, aesthetic or structural defects with pinpoint accuracy. Meanwhile, Pilot configures and organises this data, enabling the user to set the desired tolerance thresholds. Based on Organic AI, a solution inspired by nature, the system’s learning capabilities mean that users can continuously improve the qualitative performance of the production team. This quality control can be carried out on an ongoing basis for internal manufacturing or by subcontractors. Visitors to EPHJ may also be interested in the company’s annual user licence lease programme. Above a threshold of around CHF 15,000, human know-how can be supplemented with AI automation to improve quality at manufacturing companies.
