Guide for cutting:

A: Rotate the saw blade without cutting: Especially when first- time using the new saw blade, the blade should be rotated without cutting for over 30 minutes, and should be used with water in summer hot weather. The purpose is to eliminate the influence of segment to the saw blank during the welding course, and keep high internal quality memory when the saw blades is running under high speed.

B:?According to the length, width, and height of stone block to adjust the running switch, the rise and fall of saw blade or the block vehicle should be in valid range. Before cutting the distance between segment and the highest position of stone block should be 10-20mm. After the cutting the distance between the segment and the bottom of stone block should be 20-40mm. When the cutting of saw blade is changed from left to right or right to left, the blade should be out of stone block completely, the distance should be at least 150-200mm to avoid the strike of blade to the block.?

C: The saw blade can only cut the block after steady rotation, when the segment is touching the stone block the saw blade can not be loaded to run(rotate), also when the blade is under cutting in the block the rotation can not be stopped until the blade is out of block completely.

D:?Under cutting if find the stone block is vibrating, please stop the cutting immediately, cutting can be continued?only when the block is settled steadily.

E:?Under cutting if find any un-normal low cutting speed or the blade is nipped, it is possible that the strap is sliding or the compaction nuts become less crowded or the cutting depth is too much or the feed speed is too fast, which concerned should be adjusted in time.

F: The leaner speed should be adapted to the hardness and the type of abrasive of stone;?we suggest the following leaner speed according to different type stone?for your reference

G: Recommended cutting techniques of Multi-blades for reference:

Granite Class	Down Feeding Speed (Forward + Backward)	Cross Speed(m/min)
??Class 1	1.2-1.5mm + 1.1-1.3mm	12-15
??Class 2	0.7-1.0mm + 0.6-0.9mm	?????12-15
??Class 3	0.5-0.6mm +0.4-0.5mm	?????11-13

H:?Feed Speed, this is depending on the performance of cutting tools usually means the quality of segment. Every type tool when the cutting depth is confirmed then the feed speed has its own range. If the speed is too high, then the diamond of segment will be consumed quickly even fall from the bond, then the life of the segment will be short. If the speed is too low, then the blade's sharp-self course can not be conducted normally so that the blade becomes blunt to lose cutting ability. As usual, the feed speed should be slow when the blade enter the cutting, and average when it is cutting.?

I:?Regarding the cutting depth of medium hard stone such as marble, limestone which can be cut out one time, as to hard or abrasive stone such as granite, sandstone which should be cut for more times. By using single blade to cut granite, as usual the cutting depth is 4-8mm, cut marble the cutting depth is 15-30mm, multi-blades two sides cut hard granite, the cutting depth is 3-5mm, anyhow, the cutting depth should be decided by the hardness of stone, the performance of saw blade and cutting machines.

J:?If the rotation direction of the saw blade is same as the movement direction of stone, we call it same-direction-cutting; otherwise we call it contradict-direction-cutting. When the cutting is under contrary direction, there is a rising vertical strength which makes a trend of lifting up the stone block. So, in order to make the block steady, under same cutting conditions, should try to use same-direction-cutting. When under contradict-direction-cutting the cutting depth should be reduced, as usual it should be 1/3-->1/2 of same-direction-cutting depth.
