When using our high-quality Ferro-Titanit® carbide-alloyed materials, the quality of the surface is of decisive importance for the service life of the tools and machine components. Grinding to the best possible surface quality should generally be followed by polishing with diamond polishing paste in order to obtain the optimum surface quality. Diamond fine grit D 15 (10 – 25 μm) is used for rough-polishing, while fine-polishing is performed using D 3 (2 – 5 μm). If necessary, this can be followed by polishing with D 1 (1 – 2 μm).
