Which
abrasive particle would you choose for grinding tungsten carbide tool inserts?
Silicon
carbide
Aluminium oxide
Diamond
Cubic
boron carbide
Diamond
Since
carbides, high speed steel(HSS), ceramics and some other materials used to
makecutting tools can be nearly as hard as conventional abrasives, the job of
sharpening those falls to a special class of abrasives known as super abrasives
like diamond and the cubic boronnitride (CBN).
Hence,
the correct option is (C).
