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.
