flat cutting disc Granularity

The diamond particle size in the common range of 30/35 to 60/80. The more hard rock, should be selected with a finer granularity. Because under the same pressure conditions, stone cutting disc‍ the more detailed the more diamond sharp cut in favor of hard rock. Further, the general requirements of a large-diameter blade cutting efficiency high, the particle size should be selected with a thick, such as 30/40, 40/50; lower small-diameter blade cutting efficiency requirements sectional smooth rock cutting, should to a smaller particle size, such as 50/60, 60/80. 

Segment concentration 

The so-called diamond concentration, refers to the density distribution in the working layer of diamond carcass (ie, the weight of the diamond contained within the unit area). "Norms" provides work every cubic centimeter carcass containing 4.4 karats of diamonds, its concentration was 100%, with 3.3 karats of diamonds, its concentration was 75%. Represents the volume concentration of the volume occupied by the number of diamond flat cutting disc‍ agglomerates, and that, where a concentration of 1/4 volume of the total volume of diamond is 100%. Increasing the concentration of diamond is expected to prolong the life of the blade, i.e., reduced because of the increased average concentration of each piece of diamond cutting forces suffered. However, increasing the concentration will increase the cost of the blade, the most economical and thus there is a concentration, and the concentration increases with increasing cutting rate. 

Blade hardness 

Generally, the higher the hardness binding agents, the stronger its wear resistance. Thus, when a large rock cutting abrasive, hardness should be high binding agent; when cutting soft rock material, the hardness of the binding agent should be low; grinding when cutting large and hard rock, the stainless steel cutting discs‍ binding agent should be moderate hardness .
