1. Grinding A small piece of specimen is cut by a metal-cutting-saw. After cutting operation, burrs on the edges of the specimen should be carefully removed by a fine file or coarse grinding paper. The silicon carbide grinding papers are held flat in a unit containing water facility for lubrication purpose.

Get PriceFor 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).
Get PriceGrinding & Polishing Either 240 [P280] or 320 [P400] grit SiC waterproof paper may also be used for the planar grinding step. An UltraPol cloth produces better surface finishes than an UltraPad cloth, but the UltraPad cloth has a longer useful life. A ChemoMet cloth is recommended when edge retention is critical.
