Lapping, polishing, superfinishing

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.

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.

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.

Single-sided lapping, polishing machines manufacture

By virtue of its kinematics and design, our single-sided equipment can obtain perfectly flat surfaces with a remarkable polish quality.

More

Double-sided lapping, polishing machines manufacture

By virtue of its kinematics and design, our double-sided equipment can obtain perfectly flat and parallel surfaces while controlling the thickness and the surface finish.

More

Lapping and polishing slurries

We have developed two slurry families: water-based and oil-based.

More

Tooling, carriers and templates

We design and produce carriers for all types of double-sided machine.
