Dressing tools

During the grinding process, there are many factors affecting the quality of the tool, e.g. concentricity, geometric shape and the optimal effective roughness of the grinding disc surface.


Medidia processes only high quality mono-crystalline diamonds, CVD diamonds and PCD cutting materials.


In addition to manufacturing the high precision tools, Medidia also offers its discerning customers a comprehensive service. We always find an effective and meaningful solution for your project.
