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 saw blade to maintain its inherent quality under high-speed rotation memory.

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 in a symmetrical position of the workbench to ensure that the work trolley and blocks are stable without shaking or shaking phenomenon.

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. 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.

Test cutting can be performed only 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, and the rotation of the saw blade is not allowed to stop during cutting. It can be stopped after exiting the saw blade.

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.

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

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.

The feed speed mainly depends on the properties 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 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". 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 Calculate by cutting area (cm2/min). Tip: The first entry or the first three walks of each board should be halved.

The cutting depth can be cut through at one time for medium-hard stones such as marble and limestone, and for hard stone and highly abrasive materials 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. It depends on the hardness of the stone, the performance of the saw blade and the sawing machine used. The following efficiency table is recommended for you reference. Common material cutting efficiency table Note: "Level 1" means low power finishing; "2" means high power roughing.

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. In reverse cutting, due to an upward vertical component, it creates a tendency to lift the stone. Therefore, to stabilize the stone, under the same conditions, Down cut should be used as much as possible. When using reverse cutting, the cutting depth should be reduced, generally reduced to 1/3-1/2 of the down cutting.

To sum up, the basic requirements for selecting the cutting process are: for the stone with low hardness and good cutting performance, it can be deep cut and walk slowly, and vice versa. For the same stone and the corresponding saw and saw blade, the cutting efficiency should be used. High, cutting board quality is good, the process parameters of saw blade and long life of the substrate shall prevail. The four are complementary to each other, and the lips and teeth are dependent. If the cutting speed of the saw blade cannot be maintained, it indicates that the saw blade is blunt, and the cutting depth should be reduced and the cutting speed should be increased to sharpen the saw blade.
