Metallographic grinding and polishing insight | Struers.com

Plane grinding with diamond is the best choice to ensure flat samples from the very beginning of the preparation. Fine grinding with either MD-Largo or MD-Allegro will provide the best possible planeness. To avoid relief, preparation time and the type of polishing cloth used are the most important parameters.
