Out of its desire to constantly improve customer service and quality, PBMC SA has pooled together decades of experience in manufacturing and industrialisation of micro-mechanical components, machine design, development of specific tools (fixtures, carriers) and formulating polishing slurries.

We control each step of the process (lapping, polishing, superfinishing) to obtain the requisite geometry and surface finish on your parts.

We can handle any type of part: trays, washers, main plates, bridges, windows, wafers, links, insulators, etc.
In all rigid materials: metals, ceramics, crystals, glasses, natural materials, composites, etc.
Down to very low thicknesses of 0.10 mm

Based in La Chaux-de-Fonds (Neuchâtel canton), in the centre of watchmaking country, our strategic position means that we are both close to our historical customers and the gateway to Europe.
