Grinding Abrasives
Grinding abrasives are available in several forms (belts, discs, rolls/sheets, stones and wheels), minerals (aluminum oxide, diamond, silicon carbide, zirconia alumina) and backings (adhesive, non-adhesive, ferromagnetic) from which to choose.
Belts
Belts are used for high speed grinding of hard metals. Zirconia alumina is best for super alloys, aluminum oxide for ferrous metals and silicon carbide for general grinding applications.
Stones
Grinding stones are used on grinding machines for coarse, rapid planarization of samples in a central force sample holder configuration.
Each product is properly sized for compatibility with all machine types.
Aluminum oxide is recommended for ferrous metals in the range of 250 to 800 HV and silicon carbide for non-ferrous alloys or a mix of both ferrous and non-ferrous ranging in hardness from 40 to 250 HV. Choose coarse grit for soft metals, fine(r) for harder metals.
