1, idling: especially when the new substrate is used for the first time, it needs idling for about 30 minutes, and it needs idling with water in summer and high temperature season. Its purpose is to further eliminate the influence on the matrix when welding the cutter head and enhance the high-speed rotation of the saw blade.

State to maintain the internal quality of memory.

2, block shall not be less than 0.5m3, and placed safely, the bottom should be mat wood, block should be fixed firmly, block should be located at work.

In the symmetrical position of the workbench, ensure the stability of the working trolley and raw materials, and there can be no shaking and trembling.

3. Adjust the travel switch according to the length, width and height of raw materials, so that the lifting of the saw blade and the travel of the skip are within a reliable and effective range. Before sawing, the cutting edge of the saw blade should be 20 mm away from the blank10 ~. After sawing, the cut is far away from the bottom of the blank.

Department should be 20-40 mm, before the saw blade moves left and right, all the saw blades should exit the blank kerf, and the distance should not be less than150-20-40 mm to prevent the saw blade from touching the blank.

4. Only after the saw blade idling is stable can the trial cutting be carried out. It is not allowed to start the saw blade when the edge of the saw blade touches the raw material. It is not allowed to stop the rotation of the saw blade when cutting, and it can only be stopped after exiting the saw gap.

5, cutting, such as found that the block shaking, should immediately stop cutting, after being block fixed firmly, can continue to work. During cutting, it is not allowed to move the stop at will.

6. When cutting, it is found that the saw blade obviously slows down or even sticks, which may be caused by belt slipping, loose compression nut or too deep cutting depth and too fast cutting speed, so it should be adjusted in time.

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

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

Life.

8, feed speed, mainly depends on the performance of processing materials, for each material in a certain cutting depth, there is a certain range of feed speed, if the speed is too high, it will make the diamond wear faster or even fall off, resulting in the consumption of saw blades.

Fast, if the speed is too low, the self-sharpening process of the saw blade can not be carried out normally, thus "grinding and slipping" and losing the cutting ability. In general, when cutting or even sawing, the feed speed is slow. For the common good

For 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).

Tip: The first feed or the first three moves of each board should be halved.

Feed speed unit of common materials saw blade: mm/mi

9, cutting depth for medium hardness stone such as marble, limestone can be cut through at a time, for hard stone and abrasive such as granite, sandstone should be cut step by step, single saw cutting granite, cutting depth is generally

10-20 mm, and the cutting depth of marble is

50- 100 mm, cut multiple pieces of hard granite on both sides, and the cutting depth is 3-5 mm each time. According to the hardness of stone and the performance of saw blade and sawing machine, the following efficiency table is recommended for your reference.

Testing.

Note: "1 stage" means low power fine addition.

Work; "2" means high-power rough machining.

10, the rotation direction of the saw blade is the same as the stone feeding direction, indicating forward cutting, and vice versa. When cutting backward, due to the vertical component upward,

Form the trend of lifting stone, therefore, in order to stabilize stone, under the same conditions, direct cutting should be adopted as far as possible. When using reverse cutting, the cutting depth should be reduced, which is generally 1/3- 1/2 of forward cutting.

1 1. To sum up, the basic requirements for choosing cutting technology are: for stones with low hardness and good cutting performance, you can walk slowly and deeply, and vice versa.

That is to say, the same stone and the corresponding sawing machine and saw blade should be based on the technological parameters of high cutting efficiency, good cutting quality and long service life of saw blade and carcass, which complement each other and depend on each other, and must not be neglected. For example when the saw blade

When the cutting speed cannot be maintained, it means that the saw blade is dull. We should reduce the cutting depth and increase the cutting speed to sharpen the saw blade.
