There are many skills in the use of diamond saw blades. These skills can help us better use diamond saw blades. Next, we will introduce the use of diamond saw blades.

There are many skills in the use of diamond saw blades. These skills can help us better use diamond saw blades. Next, we will introduce the use of diamond saw blades.

1. Idling: Especially when the new base is used for the first time, it needs to be idling for about 30 minutes. In the summer high temperature season, it needs to be idling with water. The purpose is to further eliminate the influence of the welding head on the base and enhance the maintenance of the saw blade under high-speed rotation. Memory of inner quality.

2. The blocks should not be less than 0.5m3 and 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 without shaking. , Shaking phenomenon.

3. The use skills of diamond saw blades, adjust the stroke switch according to the length, width and height of the block, so that the lift of the saw blade and the stroke of the feed cart are within a reliable and effective range. The blade edge of the saw blade should be up to 10% away from the block before sawing. ~20mm. After sawing, there should be 20-40mm between the saw blade and the bottom of the block. Before the saw blade moves around, the saw blade should be completely withdrawn from the block saw, and the distance should not be less than 150-200mm to prevent sawing. Pieces hit blocks.

4. The trial cutting can be performed after the saw blade is idling and stable. The saw blade is not allowed to start when the saw blade is in contact with the block. The saw blade is not allowed to stop during cutting.

5. 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 arbitrarily.

6.When cutting, it is found that the saw blade has obvious deceleration or even the phenomenon of clamping the knife. It may be caused by the belt slipping, the compression nut loosening or the depth of the knife, the speed of the knife being too fast, etc., and it should be adjusted in time.

7. The line speed should be compatible with the hardness and wear resistance of the processed stone. It is recommended to choose the line speed below to cut different types of stone.

Tip: When the online speed is not high, increasing the cutting efficiency will reduce the life of the saw blade.

8. The use skills of diamond saw blades and the feed speed mainly depend on the performance of the processed material. For each material, there is a certain range of feed speeds when the cutting depth is certain. If the speed is too high, the diamond will accelerate the wear. It even falls off, causing the saw blade to consume 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". In general, the feed speed is required when cutting in Slow, it should be uniform when 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 converted according to the cutting area (cm2/min).

9. The use skills of diamond saw blades. The cutting depth can be cut through at one time for medium-hard stones such as marble and limestone. For hard stone and abrasive materials such as granite and sandstone, it should be cut step by step. Single saw cutting granite, eat The depth of the knife is generally 10-20mm, and the depth of the knife for cutting marble is 50-100mm. For multiple pieces of double-sided hard granite, the depth of the knife is 3-5mm each time. The saw blade and sawing machine used should be based on the hardness of the stone. Depending on performance, the following efficiency table is recommended for your reference.

10. The direction of rotation of the saw blade is the same as the feed direction of the stone, which is forward cutting, and vice versa. When using reverse cutting, the cutting depth should be reduced, generally reduced to 1/3-1/2 of the forward cutting.
