The company

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.

If you have a new component to polish, you want to improve the quality of your parts or optimise your manufacturing processes, please contact us.
We will look at your requirements and objectives together, to implement the optimal solution.

Flatness, parallel alignment, micron (µm), roughness (Ra, Rz), brilliance, decorable surface finish, flat polishing, flat black polishing, etc. are part of your everyday vocabulary; we speak the same language.
