Selection of Grit:

Coarse granule of grinding materials bring better efficiency, while the surface of workpiece will be rough.

In the condition of satisfy the coarseness of surface, it had better to choose coarse granularity.

It is better for Resin binder grinding tools to choose 70/80(80#)and following RVD(JR1) Diamond.

It is better for Metal(bronze) binder grinding tools to choose MBD(JR2) Diamond.

Granularity number & Basal granule size of Synthetic Diamond or CBN will be seen in the former sheet(Page.2).

CBN products process ordinary steels, carbon steel and varieties of alloyed steel precede Diamond.
