Is the stone cutting piece cut unevenly? Why?

Deciding whether the stone discharge is neat, there are many factors affecting it, and it is closely related to many details of the saw blade. Today we take a look at what factors?

1. Stone cutting blade idling: Especially when the new substrate is used for the first time, it needs to be idling for about 10-20 minutes, and it needs to be idling with water in the summer high temperature season. Its purpose is to further eliminate the impact of the welding head on the substrate and enhance the cutting blade Maintain memory of intrinsic quality under high-speed rotation.

2. The cut waste should not be less than 0.5m³ and placed securely. The bottom should be covered with square wood and plugged firmly. The waste should be located on the symmetrical position of the workbench to ensure the stability of the work trolley and the waste. There is shaking and shaking.

3. Adjust the travel switch according to the length, width and height of the block, so that the stone cutting blade can be lifted and the travel of the feed car is within a reliable and effective range. The cutting edge of the cutting blade should be away from the block by up to 10-20mm before sawing. After sawing, the saw blade should be left 20-40mm from the bottom of the block. Before the cutting blade moves around the knife holder, the saw blade should be completely withdrawn from the block saw blade. The distance should not be less than 150-200mm to prevent the blade from hitting the block. material.

4. Trial cutting can only be carried out after the saw blade is idle and stable. It is not allowed to start the cutting blade when the blade of the stone cutting blade is in contact with the block material. It is not allowed to stop the rotation of the cutting blade during cutting.

5. If there is any shaking of the block material during cutting, the cutting should be stopped immediately, and the block material should be fixed firmly before continuing to work. During cutting, the block material is not allowed to move arbitrarily.

6. When cutting, it is found that the stone cutting blade has obvious deceleration or even knife clamping. It may be due to slippage of the belt, loosening of the clamping nut or too deep depth of the knife, and excessive speed of the knife. It should be adjusted in time.

7. 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 also be different. If the stone in a single order is soft, you should inform your cutting blade supplier that you are cutting The type of stone, let them provide the corresponding wear-resistant saw blade, on the contrary, if it is hard granite, you need a sharp cutting blade. And if you are cutting a wide variety of stones, you need a corresponding universal saw blade (Hint: When the online speed is not high, increasing the cutting efficiency will reduce the life of the cutting blade.)

8. The feed speed is mainly determined by the performance of the processed material. For each material, there is a certain range of feed speed when the depth of cut is fixed. If the speed is too high, the diamond will accelerate wear and even fall off, resulting in consumption of the cutting blade If it is too fast, if the speed is too low, the self-sharpening process of the saw blade will not be able to proceed normally, so that it will lose its cutting ability by "blunting and slipping". In general, the feed speed should be slow when cutting, and should be even when cutting.

9. The cutting depth can be cut through once for medium-hardness stones such as marble and limestone. For hard stones and abrasives such as granite and sandstone, it should be cut in steps. Single-piece saw cutting granite, the depth of the knife is generally 10-20mm The cutting depth of the marble cutting knife is 50-100mm, and multiple pieces of double-sided cutting hard granite, the depth of each cutting knife is 3-5mm, should be based on the hardness of the stone, the saw blade and the performance of the saw machine.

10. The rotation direction of the stone cutting blade is the same as that of the stone feed direction, and the reverse is the reverse cutting. When the reverse cutting, there is an upward vertical component force, which forms a tendency to lift the stone. Therefore, in order to stabilize the stone, the same Under the conditions, it should be possible to use cutting along. When reverse cutting is used, the cutting depth should be reduced, generally to 1/3-1/2 of the normal cutting.

11. In summary, the basic requirements for selecting the cutting process are: for stones with low hardness and good cutting performance, you can cut deep and walk slowly, otherwise cut and walk fast, that is, the same stone and the corresponding sawing machine and cutting blade should be The cutting efficiency is high, the cutting board quality is good, the process parameters of the stone cutting blade and the long life of the substrate are subject to, the four complement each other, the lips and teeth are dependent, and can not be generalized. If the cutting speed of the saw blade cannot be maintained, it means that the cutting blade is blunt. The cutting depth should be reduced and the cutting speed should be increased to sharpen the cutting blade.
