Diamond Concentration’s Influence on the Performance of Diamond Saw Blades

by Hanjiang Wang, Diamond Blade Select

The meaning of a diamond tool’s diamond concentration is the weight of the diamonds in a unit volume of the diamond tool’s working layer, and it is defined that when each cubic centimeter contains 0.88g diamonds, the concentration is 100%. This definition also applies to CBN abrasives.

Diamond concentration greatly influences the performance of a diamond saw blade. If the concentration is too low or too high, the ideal cutting result will not be got. The commonly adopted concentration is between 25% and 75%. Generally, when the concentration increases, the diamond blade’s sharpness and cutting efficiency drop, while its service life increases. So when high cutting efficiency is required and the cutting roughness requirement is not high, diamond blades with low diamond concentration and coarse diamond grit are popular.

Diamond concentration also influences the power consumption of the saw machine. When the concentration increases, the power consumption also increases.
