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. Through the best saw blades and cutting efficiency, service life, really should be selected according to the different nature on the stone saw line speed. When sawing granite, saw line speed may be selected inside the 25m~35m/s range. High silica content is difficult for sawing of granite, remove saw line posted speed limit. During output of granite tile, make use of a smaller diameter diamond circular saw blade, line speeds can reach 35m/s.
(2) feed speed: feed speed stone by cutting feed rate. Effect of cutting rates, the dimensions of saw blade sawing regions of stress and warm. Its value should be selected good nature of stone by cutting. In General, cutting soft stone for instance marble, can be appropriate to improve final results of feed, feed speed is too low, more conducive to improving the cutting rate. Cutting granite of thin grain structure, homogeneous, could be appropriate to raise the pace of feed, feed speed is too low, diamond blade may be easily even. Cutting coarse grain structure of soft and hard granite which is not all, should reduce entry speed, otherwise it will lead diamond saw blade vibration due to fragmentation reducing the interest rate of cutting. Feeding speed of sawing of granite in the 9m~12m/min range selected.
(3) cutting depth: wear of diamond cutting depth is involved, effective cutting, sawing stone saw blade force and nature of important parameters. Generally speaking, when a type of diamond buzz saw blades speed is high, should simply select the small depth of cut elimination, from current technology, depth with the cutting diamond could be selected among 1mm~10MM. Usually with a large diameter saw blade when cutting granite block, between cutting depth is usually controlled in 1mm~2mm, simultaneously reducing approach speed. If your line speed would be the larger of diamond circular saw blade, cutting depth needs to be selected. However , if sawing machine performance and the strength with the tool from the scope in the license, make an attempt for taking a bigger concentration cut cutting to enhance cutting efficiency. When on the surface individuals absolutely vital, you should employ small depth of cut.
Second, other influencing factors
(1) diamonds size: common inside scope of diamond grain size in 30/35~60/80. Steel solid, strongly advised to select an inferior size. Because under conditions of equal pressure, sharp diamonds as small as possible, to reduce into solid rock. Furthermore, generally requires high cutting efficiency of huge-diameter saw blade should decide on a coarser granularity; inefficient sawing small diameter saw blade, require rock cutting section smooth, use a finer granularity.
(2) power of Cutter: the so-called diamond concentration, refers to the diamond within the density matrix in the distribution. Enhances the power of diamond is predicted to increase the life span of saw blade, with the increased concentration which cuts down on the average force of each diamond. But increasing depth must increase the costs from the saw blade, so there exists a concentration of most economic, Cheng cutting rate increase plus the concentration increases.
(3) the hardness in the knife head bond: in the main, bond hardness higher, its greater effectiveness abrasion. Therefore, if you are cutting abrasive rocks, bond hardness ought to be high; when the saw when cutting material of soft rock, bond hardness should be low when cutting if your abrasive and hard rock, bond hardness should be moderate.
(4) effect and temperature effect and ground damage: technique of diamond buzz saw blades in cutting stone, go through centrifugal forces, such as sawing, sawing qiere alternating loads.
