1.Idling:especially when the new substrate is used for the first time,it needs to be idle for about 30 minutes.In the summer high temperature season,water is required to be idling.The purpose is to further eliminate the influence on the substrate when welding the cutter head and enhance the saw blade to maintain at high speed.Memory of intrinsic quality.

2.The block material should not be less than 0.5m3,and it should be placed securely.The bottom surface should be padded with square wood.The plug should be solid and secure.The blockage should be located at the symmetrical position of the workbench to ensure the stability of the work trolley and block materials.Trembling.

3.Adjust the travel switch according to the length,width and height of the block material,so that the saw blade lifting and the travel of the skip are within a reliable and effective range.Before the sawing,the blade edge should be 10-20mm away from the block.After sawing,the sawing edge should be 20-40mm away from the bottom of the block.Before the saw blade moves left and right,the saw blade should be completely removed from the block sawing.The distance should not be less than 150-200mm to prevent the saw blade from colliding.material.

4.After the saw blade is stable and idling,the test cutting can be carried out.When the blade edge is not in contact with the block material,the saw blade is not activated.The saw blade is not allowed to rotate during the cutting,and must be stopped after exiting the saw blade.

5.If the blockage is found to be swaying during cutting,the cutting should be stopped immediately.After the blockage material is fixed firmly,it can continue to work.During the cutting,it is not allowed to move the block material arbitrarily.

6.When cutting,it is found that the saw blade has obvious deceleration or even the phenomenon of clamping.It may be caused by belt slippage,loosening of the compression nut or too much depth of the knife,too fast cutting speed,etc.,and 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 select the following line speed to cut different types of stone.

Tip:Increase the cutting efficiency when the line speed is not high,which will reduce the life of the saw blade.

8.The feed speed depends mainly on the performance of the processed material.For each material,when the cutting speed is within the depth of cut,if the speed is too high,the diamond will accelerate wear and even fall off,causing the saw blade to consume too fast.If the speed is too low,the saw blade will not be able to perform normally due to the self-sharpening process,thereby"blunting and slipping"and losing the cutting ability.Under normal circumstances,the feed speed should be slow when cutting in.It should be even when sawing.For common typical materials,when the depth of cut is 20mm,the following feed speed table is recommended for your reference.When the thickness changes,the cutting speed can be It is converted according to the cutting area(cm2/min).

Tip:The first infeed or the first three walks of each plate should be halved.

9.Cutting depth For medium-hardness stone such as marble and limestone,it can be cut once.For hard stone and abrasive,such as granite and sandstone,it should be cut step by step.Single-piece saw cutting granite,the depth of the knife is generally 10-20mm.The cutting marble has a depth of 50-100mm and multiple pieces of double-sided cutting hard granite.The depth of each knife is 3-5mm.It should be determined according to the hardness of the stone,the saw blade and the performance of the saw.The following efficiency tables are recommended.For your reference.

Note:“Level 1”means low power finishing;“2”level means high power roughing.

10.The direction of rotation of the saw blade is the same as that of the stone feed direction,and vice versa,while the reverse cut,due to the upward vertical component force,forms the potential of picking up the stone.Therefore,in order to stabilize the stone,under the same conditions Under,try to use cis cutting.When reverse cutting is used,the cutting depth is reduced,generally to 1/3 to 1/2 of the cis-cut.

11.In summary,the basic requirements for selecting the cutting process are:for stone with low hardness and good cutting performance,it can be deep and slow,and vice versa,that is,the same stone and the corresponding sawing machine and saw blade should be The cutting efficiency is high,the quality of the cutting board is good,and the process parameters of the saw blade and the substrate have a long service life.The four complement each other,and the lips and teeth are dependent,and the whole can not be partial.For example,when 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 to increase the cutting speed to sharpen the saw blade.
