Metallographic grinding and polishing insight

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.

Grindability an overview ScienceDirect Topics

Grindability an overview ScienceDirect Topics

The test for grindability ASTM D409 utilizes a ball-and-ring-type mill in which a 50 g sample of closely sized coal is ground for 60 revolutions after which the ground product is screened through a 200-mesh sieve and the grindability index is calculated from the amount of undersize produced using a calibration chart. The results are converted .
