Excellent for fine grinding of samples with a hardness between 150 HV and 2000 HV. Aka-Piatto 1200+/15 µm is used for fine grinding and removes deformations created by the previous flat grinding step. Aka-Piatto+ has a higher concentration of diamonds than Aka-Piatto, which makes the grinding less aggressive due to a lower specific pressure. Aka-Piatto+ is therefore the optimal choice for grinding brittle samples such as ceramics, cermets and sintered carbides. The samples are ready for a polishing step with 3 µm after using an Aka-Piatto 1200+/15 µm.
