EPHJ 2023

The unique international trade show dedicated to high precision

EPHJ (Environnement Professionnel Horloger et Joaillier) is the meeting place for professionals in the watch and jewelry industry. The show will be held in Geneva at the Palexpo Exhibition Center from June 6 to 9, 2023. It will showcase the latest innovations, technologies and products in the watch and jewelry industry. Visitors will have the opportunity to learn about new developments and trends in the industry, make new contacts and maintain existing business relationships.

For our customers in the watch industry, the technical aspect is particularly important: every component must fit 100 percent perfectly. This is only the case if the surface structure is right. Our experts in high-precision surface polishing and finishing have extensive know-how in the use of diamond micro grains to achieve first-class results.

Thanks to our extensive portfolio of innovative products, we can find the right solution for any surface finishing challenge. Visit our booth D24 and meet Mr. Xavier Fourny and his team.

Highlights at our booth

Pureon offers a wide range of polishing pads suitable for a variety of materials. Pad geometries and surfaces are optimized for high material removal and excellent surface finish. This makes our polishing pads versatile for the most advanced applications.

The new IRINO-PRO composite polishing pad closes the gap between lapping on metal plates and polishing on pads. It is best suited for super hard and brittle materials such as sapphire, SiC, ceramics or hard metals. At the same time, IRINO-PRO offers excellent workpiece geometry and flatness without edge rounding. When combining our application-tailored diamond suspensions with IRINO-PRO, surface qualities of up to 1 nm Ra can be achieved! Thanks to the dressable system, it can be applied to double and single side machines. IRINO-PRO is equipped with a self-adhesive backing and can therefore easily be applied to any existing metal carrier plate.
