Concentration

As a basic value for DIAMOND/CBN concentration in grinding wheels, 100 is equivalent to 4.4 carats per cubic centimeters (0.88 gm/cm³) Other concentrations are worked out prorata from this figure and are given below.

Concentration	Wt. of Diamond/CBN per CC of the Bondeding Section
25 con.	1.1 ct/cm2
50 con.	2.2 ct/cm2
75 con.	3.3 ct/cm2
100 con.	4.4 ct/cm2
