Diamond saw blade is a tool for cutting stone with a diameter ranging from 105-3500mm. Most saw blades with a diameter less than or equal to 550mm are used for the cutting of infrared bridge cutting machines, and the usage and cutting process are relatively simple. This article mainly introduces the detailed cutting skills of large-size block saw blades with a diameter range of 600-3500mm.

1: Start-up idling: At the beginning of sawing, especially when the diamond saw blade is used for the first time, in order to make the saw blade more stable, it is necessary to let the saw blade idle for about 30 minutes. If it is in the high temperature season in summer, it needs to be idling with water. The purpose of this is to further eliminate some influences on the substrate during the welding of the segment, and it can also be enhanced that the saw blade has smaller end jump and radial jump under high-speed rotation.

2: In the process of cutting stone blocks, the volume of the blocks shall not be less than 0.5m3. Because the smaller the block size is, the lighter the weight will be, and jitter will occur during the cutting process. In terms of preventing shaking, the following three points should be done: 1: The blocks need to be placed securely, the bottom surface should be padded with square wood to assist in fixing, and the fortress should be solid. 2: The blocks should be located in the symmetrical position of the workbench, and cannot be placed on one side or one foot. 3: If the block is too inclined,we can use the block trimmer to shape it first, and cut the bottom surface flat, which can ensure the stability of the work trolley and the block without shaking.

3、If the gantry cutting is used to process the stone, it is necessary to adjust the appropriate travel switch according to the length, width and height of the stone blocks. It is necessary to ensure the lifting stroke of the saw blade, and it is also necessary to adjust the travel of the trolley of the gantry to be within a reliable and effective range. In the actual operation process, before sawing, the cutting edge of the diamond saw blade should be up to 10-20mm away from the block. After sawing, there should be a 20-40mm bottom plate between the saw edge and the bottom of the block to prevent the plate from being pressed to the saw blade and damage to the saw blade and plate due to direct cutting to the bottom. If it is a Chinese-style tower saw blade machine, it is necessary to adjust the left and right stroke and front and rear stroke of the main shaft, the cutting depth of the segment, the diameter of the segment and other parameters according to the actual size of the block, and complete the cutting automatically.

4. During the idling process of the saw blade, the saw blade shakes stably, and the swing range is small and stable, so this situation can be sawed in. Do not cut directly, it is easy to cut the stone to bad shape. When the cutting is stopped, the saw blade is not allowed to be stuck in the stone, and the saw blade must be raised to a high position to avoid the block swinging and jamming the saw blade and damaging the saw blade.

5. During the cutting process, if you find that the block is shaking, you must stop the cutting work immediately, and wait for the block to be re-fixed to make sure that it will not shift or swing before cutting.

6. When the block is cut, it is found that the saw blade has obvious deceleration, or even the segment is clamped, which may be due to belt slippage, loose nut or too deep cutting depth, too fast cutting speed, etc., and should be adjusted in time.

7.The linear speed is also called the cutting speed. The faster the cutting speed, the faster the consumption of the diamond saw blade and the shorter the service life. The slower the speed of the segment cutting, the slower the consumption of the diamond saw blade, and the longer the life of the saw blade will be obviously felt. Therefore, the life of generally sharp saw blades is generally not long, and the life of non-sharp saw blades will be longer.

8.The feed speed, also known as the cutting depth, the deeper the cutting depth, the more the saw blade slips during the process of cutting the stone. Once the saw blade slips, the cutting will shift and the stone will not be able to be cut. Therefore, reducing the cutting depth of the segment can obviously solve this problem.

9.In the process of gantry blade machine cut stone, the rotation direction of the diamond saw blade is the same as the moving direction of the trolley, which is called forward cutting, and vice versa is called reverse cutting. In the process of reverse cutting, there will be an upward vertical force, which sometimes lifts the stone. Especially when the blade is stuck, reverse cutting is very easy to occur, which will damage the mechanical spindle, so try to use straight cutting and less reverse cutting. Even if you use reverse cutting, reduce the cutting depth, preferably in the range of one-third to one-half of the speed of the straight cut.

10: Generally speaking, the diamond saw blade cutting stone can be summed up in the following sentences:

Low cutting depth is easy to cut soft stone. Deep cutting depth should be slow cutting speed. High hardness, hard to cut, shallow cut, fast walking, stable idling is very important, and it is more suitable to go deep and reverse shallow.

In general, there will be many problems in the process of diamond saw blade cutting, but in the final analysis, it is nothing more than encountering problems and solving problems. Understand the basic principles of stone cutting, master the core knowledge of the cutting process, and be familiar with the process of stone processing. Naturally, you can be invincible.
