Factors size diamond saw blade

The grit size used in the 30/35 ~ 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  green concrete blades rock cutting section, preferably to a

smaller particle size, such as 50/60, 60/80.
Segment concentration
The so-called diamond concentration, the diamond in the working layer is

the 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 average

cutting force suffered. However, increasing concentrations will increase

the cost of the blade, so there is concrete core bits  a concentration of the most

economical, and the concentration increases with the cutting rate.
Blade hardness
Generally, the higher the hardness binding agents, the stronger its wear

resistance. 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 binding agent should be moderate hardness .
Effect
Diamond saw blades in the process of cutting stone, will be centrifugal

force, cutting power, cutting hot alternating load effect.
Because force and temperature effects caused by diamond saw blade

grinding breakage.
Force effects: In the cutting process, the blade subject to axial force

and tangential force. Because there is  wood band saw blades in the circumferential direction

and the radial force, in the axial direction so that the blade wavy dish

in radial direction. Both can cause deformation of the rock section is

not flat, stone wasted, sawing noise, vibration intensified, resulting

in diamond caking early damage, reduced blade life. +++
