Diamond ultra-thin cutting discs of granularity: diamond ultra-thin grinding disc particle size in the range of 30/35 to 60/80. The more hard rock, should be selected with a finer granularity. Diamond ultra-thin cutting wheel under the same pressure conditions, the more detailed the more sharp, it is beneficial to cut into the hard rock. In addition, the generally large diameter of the saw blade sawing efficiency requirements, should select the coarser particle size, such as 30/40, 40/50; low efficiency of the small diameter of the saw blade sawing require smooth rock sawing sectional, should Optional finer granularity, such as 50/60, 60/80.

The tip concentration: the so-called diamond concentration of the ultra-thin cut sheets, refers to the distribution density of the diamond thin cutting chip in the working layer carcass (i.e. contained in the unit area weight of the diamond thin cutting sheet). "Norms" provisions per cc carcass containing 4.4 kt diamond thin cutting sheet, a concentration of 100%, containing 3.3 carat diamond thin cutting the sheet, the concentration of 75%. The volume concentration of said diamond ultrathin agglomerates dicing sheet how much of the volume occupied by, and provides, when the concentration of 1/4 of the volume of the total volume of the diamond thin cutting chip is 100%. Increase the diamond ultra-thin cutting discs concentration is expected to extend the life of the blade, because the increase in the concentration that reduces the average cutting force of each piece of diamond ultra-thin cutting discs suffered. But increased depth inevitably increase the cost of the blade, and thus there is a concentration of one of the most economic, and the concentration with VS shear rate increases.

Tip hardness of the binding agent: In general, the higher the hardness of the binding agent, the stronger its wear resistance. Thus, when a large rock sawing abrasive, the hardness of the binding agent should be high; when sawing soft rock material, the hardness of the binding agent should be low; When sawing abrasive and hard rock, the hardness of the binding agent should be moderate .
