Selection of diamond distribution concentration

In a certain range, when the diamond concentration changes from low to high, the sharpness and cutting efficiency of Wholesale Diamond Saw Blade for Granite supplier china gradually decrease, but the service life gradually extends, but when the concentration is too high, Wholesale Diamond Saw Blade for Granite supplier china will become blunt. However, the method of low concentration and coarse particle size can improve the efficiency. Taking advantage of the different effects of various parts of the cutter head on sawing, different concentrations (that is, lower concentrations can be used for the middle layer of more than three layers) are used to form an intermediate groove during sawing, which is conducive to preventing the deviation of Wholesale Diamond Saw Blade for Granite supplier china, thus improving the quality of stone processing.

Selection of diamond strength

The strength of diamond is an important index to ensure the cutting performance. Excessive strength will make the crystal hard to break, the abrasive grains will be polished in use, and the sharpness will be reduced, leading to the deterioration of the performance of Wholesale Diamond Saw Blade for Granite supplier china; When the diamond strength is not enough, it is easy to break after impact, and it is difficult to bear the important task of cutting. Therefore, the strength should be 130 ≤ 140 N.

Linear speed, cutting depth and feed speed of Wholesale Diamond Saw Blade for Granite supplier china

(1) The linear speed of Wholesale Diamond Saw Blade for Granite supplier china shall be selected according to the performance of different stones and the best service life and cutting efficiency of Wholesale Diamond Saw Blade for Granite supplier china. When cutting granite, the linear speed of granite diamond saw blade can be selected in the range of 25m~35m/s. For granite with high quartz content and difficult sawing, the lower limit of the linear speed of the saw blade should be taken. In the production of granite bricks, the diameter of gold Diamond Saw Blade for Granite supplier china is small, and the linear speed can reach 35m/s.

(2) Saw depth of Wholesale Diamond Saw Blade for Granite supplier china: generally speaking, when the linear speed of Wholesale Diamond Saw Blade for Granite supplier china is high, a smaller cutting depth should be selected. According to the current technology, the depth of Wholesale Diamond Saw Blade for Granite supplier china can be selected between 1mm and 10mm. When cutting granite waste of large diameter saw blade, the cutting depth can be controlled between 1mm and 2mm, and the feed speed can be reduced at the same time.

When the linear speed of Wholesale Diamond Saw Blade for Granite supplier china is large, a larger cutting depth should be selected. However, when the sawing machine performance and tool strength are allowed, the cutting concentration should be increased as much as possible to improve the cutting efficiency. When the surface needs to be machined, small depth cutting shall be used.

(3) Feeding speed: Generally speaking, the cutting speed of sawing soft stone, such as marble, can be appropriately increased. If the feeding speed is too low, it is more conducive to improving the sawing rate. Wholesale Diamond Saw Blade for Granite supplier china can appropriately increase the feeding speed when sawing fine grain structure and relatively uniform granite. If the feeding speed is too low, the diamond edge is easy to grind.

However, when Wholesale Diamond Saw Blade for Granite supplier china are used to cut granite with coarse grain size and uneven hardness and softness, the feeding speed should be reduced, otherwise the vibration of Wholesale Diamond Saw Blade for Granite supplier china will cause diamond fragmentation, and the sawing speed should be reduced. The feeding speed for sawing granite is generally within the range of 9m~12m/min.
