The sparkle of diamond saw blades is the factor that affects the efficiency of diamond saw blades.

The cutting depth is an important parameter related to the stress of the diamond abrasion effective saw blade and the properties of the stone being cut. Generally speaking, when the linear speed of the diamond circular saw blade is high, a small cutting depth should be selected. According to current technology, the depth of the diamond saw blade can be selected between ~. Usually when cutting granite blocks with a large diameter saw blade, the sawing depth can be controlled between ~, and at the same time the feed speed should be reduced. When the linear speed of the diamond circular saw blade is large, a large cutting depth should be selected. However, within the permissible range of saw machine performance and tool strength, a larger cutting concentration should be used for cutting to improve cutting efficiency. When there are requirements for the machined surface, small depth cutting should be used.
Granite Saw Blades
When choosing a cutting machine correctly, special attention should be paid to the power, speed, rigidity, accuracy, etc. of the cutting machine. ￠The following diamond saw blades are suitable for use with ~speed~adjustable speed cutting machines, ￠~saw blades are suitable for use with speed~adjustable speed cutting machines, medium-diameter stone saw blades are suitable for use with electric or above linear speed adjustable-speed cutting machines, and medium-diameter engineering saws It is advisable to use an electric or gasoline or diesel-powered cutting machine with an adjustable speed above the linear speed. The power of the large-diameter saw blade cutting machine is related to the diameter of the saw blade and the number of diamond saw blades. For example, in China, the power of a single-blade saw machine ~ the speed ~.
Correct installation The correct installation and installation accuracy of the diamond saw blade are closely related to the cutting efficiency, cutting quality and service life of the saw blade. After installation, make sure that the saw blade runs smoothly and does not produce vibration during the cutting process, except for the influence of the saw blade's own quality and the rigidity of the cutting machine. When installing the saw blade, first ensure that the cutting direction marked on the saw blade is consistent with the rotation direction of the cutting machine spindle. Clean the saw blade installation hole and the contact surfaces between the cutting machine spindle flange and ensure that they are in contact with each other. The diameter of the flat and well-formed flange should be reasonably selected according to the diameter of the saw blade. If the flange is too small, the end face of the saw blade will deflect greatly during use. If the flange is too large, the weight of the spindle will increase, which will also increase the runout and reduce the processing depth of the material. After installation, the runout value of the saw blade flange must reach the specified value before use.
Reasonable selection of cutting parameters and coolant. The use of coolant has two functions. One is cooling. Due to the friction and impact between the circular saw blade and the stone during the cutting process, a large amount of heat is generated on the cutting surface, and the heat dissipation of the stone is poor, so that most of the heat is absorbed by the saw blade, especially the diamond blade. It is the first to bear the brunt, which can easily cause graphitization of diamond, and the cutter head can easily be burned and fall off. At the same time, the steel-based granite saw blade body is also prone to thermal deformation and cracking from the root of the nozzle. Use a large amount of coolant to continuously and evenly spray the cut from the front, rear and both sides of the saw blade, which will play a very good role in cooling and protecting the saw blade. Another function of using coolant is to remove chips. When the coolant reaches a certain pressure and generally requires the hydraulic pressure to be greater than that of the incision, it will take away a large amount of material chips, which is of great benefit in reducing the secondary wear of the diamond cutter head and matrix by the chips. In addition, if an emulsion type coolant is used, the hydrophilic and lipophilic properties of the emulsifier can cause a lubricating oil film to adhere to the surface of the saw blade and the rock surface, which can reduce the friction coefficient during sawing, thereby reducing the cutting time. Resistance reduces vibration. The coolant is generally cooling water. You can also add an appropriate amount of anti-rust agent to the cooling water and use an emulsion plus saponified dissolving oil Taikoo oil and other hydrophilic and lipophilic emulsifiers. Saw blade linear speed The linear speed of a diamond circular saw blade has a great impact on cutting. If the linear speed is too low or too high, it will accelerate the wear of the diamond blade, causing abnormal wear of the saw blade to accelerate, and the cutting efficiency will also decrease. This is because when the cutting speed is very low, the contact time between the diamond tip on the saw blade and the material increases correspondingly during each cutting, which intensifies the friction, increases heat, worsens heat dissipation and cooling conditions, aggravates saw blade wear and leads to line failure. If the speed is too high, the cutting depth of a single grain of diamond per unit time will be reduced, and the friction and wear of the rock on the diamond will be reduced. However, at this time, the dynamic load of the interaction between the diamond tip of the marble saw blade and the material being cut increases, which not only causes the diamond to be The loss caused by mechanical impact increases, and the loss is also increased because diamond is easy to break and fall off. The harder the material to be cut is, the linear speed of the saw blade should be lower. If the material to be cut is softer or more abrasive, the linear speed should be higher. Under certain other conditions, there will always be an optimal linear speed for diamond circular saw blades. For example, for medium and large diameter circular saw blades, it is suitable for cutting granite with high quartz content or group sawing, and granite with low quartz content is suitable for cutting. Stone, marble, limestone sandstone. Cutting productivity Cutting productivity, or cutting efficiency, is the product of the cutting depth of the saw blade and the feed speed, that is, the cross-sectional area of the material cut per unit time, expressed by / or /. Practice has shown that for the same material, increasing the cutting depth and feed speed at the same time can improve cutting productivity, but the abnormal wear of the saw blade will also increase, the service life will decrease, and the sawing power will also increase, so the cutting time will be increased. cost. Generally speaking, when cutting softer materials or highly abrasive materials, one-time forming cutting can be used. Medium-diameter saw blades are mostly used to cut plates, and most of them are cut in one time. Medium-hard and above granite should be cut in steps. After the depth of cut is determined, the feed speed can be calculated under the condition that the cutting productivity is certain.
