Diamond grinding wheels grit size

Figure 4 shows an example for the specification of bonded grinding tools with superabrasives. The common abbreviation for diamond grits is (D) and (B) for CBN (Fig. 5). The size of superabrasive grits is often given as mean diameter in micrometer instead of meshlike conventional abrasives. Therefore, the specification of grinding wheels has to be compared...

When silicon was ground together with tungsten carbide, the surface roughness improved when compared with grinding the silicon alone brittle-to-ductile transition was observed for JIS 4000 mesh size wheel. In a later study (Itoh et al., 1998), silicon and glass (BK7) were ELID lapped with metal resin diamond-bonded wheels of grit sizes of JIS 8000, JIS 120,000, and JIS 3,000,000. 

This section will focus upon the crystallization principles used to produce commercially synthetic diamond grit abrasives. The size of particles discussed here are within an envelope of about 850-200 pm for grits used mainly in stone and concrete sawing (saw sizes) and from about 200-50 pm used for grinding applications (wheel sizes).
