affect the efficiency and lifetime of diamond saw blades factors

(1) diamond size: Common diamond saw blade diamond size 30/35 to 60/80 range. The more hard rock, should be selected with a finer granularity. Because at the same pressure conditions, the more detailed the more sharp diamond, cut hard rock in favor. In addition, the general requirements of a large-diameter blade cutting efficiency is high, with the coarser particle size should be selected, for example, 30/40, 40/50; small-diameter blade cutting efficiency is low, requires smooth rock cutting section, preferably to a smaller particle size, such as 50/60, 60/80.
(2) Segment concentration: the so-called diamond concentration, the diamond in the working layer is the  tuck point blades carcass in the density distribution (i.e. contained within the unit area weight of the diamond). "Norms" provides work per cubic centimeter of the matrix containing 4.4 kt diamond, the concentration of 100%, including 3.3 kt diamond, the concentration was 75%. Volume concentration of said agglomerates in the volume occupied by the number of diamond and provides that when the volume of the total volume of the diamond 1/4 concentration of 100%. Increasing the concentration of diamond is expected to extend the life of the blade, because of the increased concentration of each piece of diamond is reduced, the  bandsaw blades average cutting force suffered. However, increasing the depth of the blade will increase the cost, so there is a concentration of the most economical, and the concentration with VS shear rate increases.
(3) binding agents head hardness: In general, the higher the hardness of the binding agent, the stronger the resistance to abrasion. Thus, when a large rock abrasive cutting, the bonding agent should be high hardness; when the cutting of soft rock material, the hardness of the binding agent should be low; when large and abrasive cutting hard rock, the diamond tool manufacturer  binding agent should be moderate hardness .
(4) force effects, temperature effects and grinding damage: cutting stone diamond saw blades in the process will be subject to centrifugal force, cutting power, cutting hot alternating load effect. Because force and temperature effects caused by diamond saw blade worn to donate damage.
