Abrasive grains embedded in PU bonding systems can achieve surface roughness values of ≤ Ra 0.1 μm. We process grain sizes up to 1500 mesh. Given the variety of materials used (e.g., soft to hardened steels, ceramics, or composites), specifying fine grinding and polishing tools is crucial for surface finish, productivity, and tool longevity. Our PU bonding systems can be manufactured with varying degrees of hardness and tailored to specific applications.

Fine grinding- & polishing tools forhigh-quality surfaces and functional surfaces . The trend towards fine and polished surfaces is increasing year by year. In the medical and food industry, fine surfaces are used to minimize bacterial adhesion. While in gear and drive technology, the focus is primarily on reducing noise, friction reduction is the main concern in engine construction. In traditional mechanical engineering, for example, durability is of high importance due to reduced notch effect. Thus, component design can be optimized accordingly.

In many areas, roughnesses ≤ Ra 0.1 μm are required. Due to the use of different materials (e.g. soft to hardened steels, ceramics or composite systems), the specification of fine grinding and polishing tools is crucial for surface results, productivity and tool life. Our PU bonding systems can be manufactured in different hardness grades and adapted to the respective application.

While material removal takes place in the grinding process, tips in the topography are mainly smoothed in the polishing process (creating a new topography). The fine grinding or polishing process involves a certain amount of pressure. The dressing process can be carried out with both stationary and rotating tools.
