  • Metallographic Abrasive Grinding

    For metallographic preparation, SiC abrasives are used in abrasive blades and for coated abrasive grinding papers ranging from very coarse 60 grit to very fine 1200 grit sizes. Bonded or coated abrasive papers of SiC are designed so that the abrasive will have a large number of cutting points (negative abrasive rank angle).

    Grinding of SpecimensFinal PolishingPressure Polishing SystemsThe initially deformed layer is reduced in depth by the application of a finer abrasive. However, the finer abrasive also produces another deformed layer, this time of lesser depth. The process is continued with finer and finer grinding and polishing abrasives. The final layer is removed chemically by etchingwith an acid or some suitable agent. During fine grinding the specimen is held so that the new finer scratches are introduceSee more on kemet.co.ukEstimated Reading Time: 6 mins
