Why can granite saw blades process flat plates?
1. It is found that the saw blade slows down significantly or even clamps the knife during cutting. It may be caused by slipping of the belt, loosening of the compression nut, too deep knife depth, and too fast cutting speed. It should be adjusted in time.
The quality of the granite saw blade itself and the effect of the final cut stone are also inseparable. Boreway specializes in the production of granite saw blades for sawing blocks , and matched the diamond head of a relatively single saw blade ., and There is a convenient and quick combination saw blade .
2. Saw blade idling: When using a new substrate for the first time, it needs to be idling for about 10-20 minutes. In summer, the temperature is high, and it needs to be idling with water to cool down. The purpose is to further eliminate the impact of welding on the substrate and enhance The saw blade maintains the memory of its inherent quality under high-speed rotation.
3. Adjust the travel switch according to the length, width and height of the block to make the saw blade lift and the travel of the feeder within a reliable and effective range. Before sawing, the edge of the saw blade should be at most 10-20mm away from the block. After sawing, there should be 20-40mm between the saw blade and the bottom of the block. Before the saw blade moves around, all the saw blades should be removed from the block saw. The distance should not be less than 150-200mm to prevent the saw blade from hitting the waste. material.
4. The cut blocks should not be less than 0.5m³, and they should be placed securely. The bottom surface should be padded with square wood, and the plugs should be solid and firm. The blocks should be located on the symmetrical position of the workbench to ensure the stability of the work trolley and the blocks. There is shaking and shaking.
5. Test cutting can be performed after the saw blade is idling and stable. The saw blade is not allowed to start when the blade edge is in contact with the block. The saw blade is not allowed to stop during cutting. It can only stop after exiting the saw blade.
6. If you find that the blocks are shaking during cutting, you should stop cutting immediately. After the blocks are firmly fixed, you can continue working. During cutting, you are not allowed to move the blocks at will.
7. The feed speed mainly depends on the performance of the processed material. For each material, there is a certain range of feed speeds when the cutting depth is constant. If the speed is too high, the diamond will wear out or even fall off, causing the consumption of the saw blade. If it is too fast, if the speed is too low, the self-sharpening process of the saw blade will not be carried out normally, and the cutting ability will be lost due to "blunting and slipping". Under normal circumstances, the feed speed should be slow during cutting, and should be uniform during sawing. For common typical materials, when the cutting depth is 20mm, the following feed speed table is recommended for your reference. When the thickness changes, the cutting speed can be Calculated by cutting area (㎡/min). (Hint: the first entry or the first three walks of each board should be halved.)
8. The linear speed should be compatible with the hardness and wear resistance of the processed stone. Due to the wide variety of granite, the corresponding hardness will be different. If the stone in a certain order is soft, you should inform your saw blade supplier that you are cutting For different types of stone, let them provide corresponding wear-resistant saw blades. On the contrary, if it is hard granite, sharp cutting blades are required. And if you cut a wide variety of stone, you need a universal saw blade (hint: when the online speed is not high, increasing the cutting efficiency will reduce the life of the saw blade.)
9. The cutting depth can be cut through at one time for medium-hard stone such as marble and limestone, and for hard stone and highly abrasive such as granite and sandstone, it should be cut step by step. For cutting granite with a single saw, the cutting depth is generally 10-20mm , The cutting depth of marble is 50-100mm, and the cutting depth of multiple pieces of hard granite is 3-5mm each time, which should be determined according to the hardness of the stone, the performance of the saw blade and the sawing machine used.
10. The rotation direction of the saw blade is the same as the feed direction of the stone, which is forward cutting, and vice versa. In reverse cutting, due to an upward vertical component, it creates a tendency to lift the stone. Therefore, it is a stable stone under the same conditions. Down cut should be used as far as possible. When using reverse cutting, the cutting depth should be reduced, generally reduced to 1/3-1/2 of the down cutting.
