Factors affecting the efficiency and life of diamond circular saw blade sawing parameters

Factors affecting the efficiency and life of diamond circular saw blade sawing parameters and hardness of diamond grain size, concentration and binding agent. Saw wire-speed, concentration of cutting and feed speed.
First, cutting parameters
(1) saw blade speeds: in practice, diamond saw blades equipment condition, line speed of saw blades and cutting quality qieshi limits of nature. In the best saw blades and cutting efficiency, service life, really should be selected using the different nature from the stone saw line speed. When sawing granite, saw line speed could be selected inside the 25m~35m/s range. High silica content is hard for sawing of granite, remove saw line speed limit. During the time of output of granite tile, work with a smaller diameter diamond buzz saw blade, line speeds can reach 35m/s.
(2) cutting depth: wear of diamond cutting depth is involved, effective cutting, sawing stone saw blade force and nature of important parameters. Normally, whenever a distinctive line of diamond circular saw blades speed is high, should simply select the small depth of cut elimination, from current technology, depth of the cutting diamond can be selected among 1mm~10MM. Usually that has a large diameter saw blade when cutting granite block, relating to the cutting depth might be controlled in 1mm~2mm, as well reducing approach speed. If your line speed is the larger of diamond buzz saw blade, cutting depth needs to be selected. But when sawing machine performance and the strength on the tool inside scope of the license, you should try to adopt a larger concentration cut cutting to boost cutting efficiency. When on the outside if you find a requisite, you may use small depth of cut.
(3) feed speed: feed speed stone by cutting feed rate. Effect of cutting rates, how big is saw blade sawing regions of stress as well as heat. Its value should be selected according to the nature of stone by cutting. In the main, cutting soft stone such as marble, might be appropriate to enhance the speed of feed, feed speed is not enought, more conducive to improving the cutting rate. Cutting granite of thin grain structure, homogeneous, could be appropriate to boost final results of feed, feed speed is not enought, diamond blade can easily be even. Cutting coarse grain structure of soft and hard granite that's not all, should reduce entry speed, otherwise it is going to lead diamond saw blade vibration a result of fragmentation minimizing the interest rate of cutting. Feeding speed of sawing of granite in the 9m~12m/min range selected.
Second, other influencing factors
(1) diamonds size: commonly used inside scope of diamond grain size in 30/35~60/80. Firm, strongly advised to pick out a smaller size. Because under conditions of equal pressure, sharp diamonds no more than possible, to chop into solid rock. Moreover, generally requires high cutting efficiency of large-diameter saw blade should select a coarser granularity, such as 30/40,40/50; small diameter saw blade sawing is inefficient, require rock cutting section smooth, make use of a finer granularity, for instance 50/60,60/80.
(2) power of Cutter: the so-called diamond concentration, is usually a Diamond-tier matrix inside distribution of density (which is contained in the diamond weight per unit area). The "norm", every milliliter of the carcass when 4.4 carats in diamonds, a concentration of 100%, when 3.3 carats of diamonds, a concentration of 75%. Concentration represents simply how much the degree of diamond inside agglomeration, and supplies that whenever a diamond the dimensions of the total amount of one-fourth concentration of 100%. Increases the power of diamond is predicted to give the life span of saw blade, due to the increased concentration which cuts down on average force of diamond. But increasing depth must improve the costs on the saw blade, so you will find there's concentration of most economic, Cheng cutting rate increase and also the concentration increases.
(3) the hardness with the knife head bond: in General, bond hardness higher, its greater potential to deal with abrasion. Therefore, while you are cutting abrasive rocks, bond hardness should be high; once the saw when cutting material of soft rock, bond hardness needs to be low when cutting once the abrasive and hard rock, bond hardness really should be moderate.
(4) effect and temperature effect and ground damage: means of diamond buzz saw blades in cutting stone, undergo centrifugal forces, like sawing, sawing qiere alternating loads.
Caused because of the force effect and temperature effect of diamond buzz saw blades worn to donate loss.
Effects: in the process of cutting, saw blade to become subjected to axial force and shear force effect. Due to role in the circumferential direction and radial force, making saw blades in axial wave-shaped, radial disc. Both deformation will result in waste of section roughness of rock, stone, when cutting large noise, vibrations, cause caking early breakage, diamond saw blade service life reduction.
Temperature effect: the more common theory is the fact: temperature effects on the procedure for saw blade mainly in two aspects: one is the reason for caking of diamond graphite; b may be the matrix of diamond and diamond particles caused by reyili slump prematurely. New study: heat generated along the way of cutting the key incoming caking. ARC temperature is not high, generally between 40~120℃. Abrasive grinding temperatures are higher, usually between 250~700℃. Coolant only reduce the average temperature with the arc area, temperatures are less abrasive. This heat isn't going to cause graphite charcoal, but adjustments to friction properties between your abrasive and workpiece and thermal stress between Diamond and additives, which cause fundamental of bending failure mechanism of diamond. Studies have shown that temperature effect would be to make maximum impact factor of saw blade breakage.
Ground damage: as the force effect and temperature over really should be, saw broken over time people usually wear. Grinding damage mainly available as these: broken abrasive wear, local, large areas along the cutting speed for forming broken, loss, mechanical abrasion. Abrasive wear:-Diamond particles and constant friction, passivation of edge planes, lost performance, boost the friction. Saw cut hot will makes diamond particles surface appears graphite of thin layer, hardness greatly reduced, increased wear: Diamond particles surface bear cross variable of hot stress, while also bear cross variable of cutting stress, on will appears fatigue crack and local broken, revealed out sharp of latest edge edge, might be more ideal of wear form; large area broken: Diamond particles in plunges remove Shi bear impact load, comparison highlight of particles and grain early consumption off; off: Alternate cut of diamond particles on bond constantly be shaking loose. At the same time, wear on the bond itself in the process of cutting and sawing thermal softening of bond. This will likely lower the bond holding force, once the cutting force about the particles over holding force, diamond particles will sink. Regardless of what rather diamond particles wear and level of load and temperature are closely related. Both depend upon Cheng cutting conditions of lubrication and cooling.
