saw - some of the factors affecting other

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  crack chaser efficiency is low, requires smooth 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 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.
Head hardness binding agents
Generally, the higher the hardness green concrete blades  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 .
Force effects, temperature effects and grinding damage
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 worn to donate damage.Force effects: In the cutting process, the blade subject to axial force and tangential force. Because there is 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.Temperature effect: the traditional theory: the influence of temperature on the blade process is mainly manifested in two aspects: First, cause agglomeration of diamond graphitization; two diamond and matrix is ​​caused by the thermal Wilson force caused premature loss of diamond particles . New research showed that: the heat generated during cutting the main incoming agglomeration. Arc temperature is not high, generally between 40 ~ 120 ℃. The abrasive grinding point temperature was high, generally between 250 ~ 700 ℃. The coolant only reduce the average temperature of the arc zone, the temperature has little effect on the grain. This does not result in graphite carbonization temperature, but will make the friction between the abrasive particles and the workpiece change in properties, and to occur between the diamond and the additive thermal stress, which led to a fundamental failure mechanisms curved diamond technology. Studies have shown that the temperature effect is to make the biggest factors blade breakage.Grinding damage: the force effects and temperature than the response, after a period of use of the blade tend to produce wear damage. Grinding damage in the form of mainly the following: abrasive wear, local  Edge Pad crushing, a large area of ​​broken off, binders direction along the cutting speed of the mechanical abrasions. Abrasive: Diamond particles and constant friction formula pieces, into a flat edge passivation, loss cutting, increasing friction. Heat causes the cutting surface of the diamond particles graphite sheet, the hardness greatly reduced, increased wear: the surface of the diamond particles exposed to alternating thermal stresses, and also the cutting under alternating stress, fatigue cracks will be partially broken, revealing a sharp new edge, is an ideal wear pattern; large area broken: diamond particles in the Leads to withstand shock loads, the more prominent grain and grain prematurely consumed; shedding: the diamond cutting force alternating binding agent particles are constantly being generated shaking loose. Meanwhile, the cutting process of the binding agent itself wear and cutting heat to soften the binding agent. This makes the gripping force decreased binding agent, when the particle is greater than the cutting force on the gripping force, the diamond particles will fall off. No matter what kind of wear and tear with the diamond particles to withstand load and temperature are closely related. Both of which are determined by Cheng cutting process and cooling lubrication conditions.
