concrete diamond blades cutting knowledge

1 , idle : in particular, a new base for the first time , the need to idle about 30 minutes, with a high temperature in summer season water needs to idle , which aims to further eliminate the matrix of the welding head, and enhance high-speed rotating blade held at state the intrinsic quality of memory.
  2 blocks of not less than 0.5m3, and placed securely , the bottom should be well- pad wood, solid plug is secured , blocks GUSHI abrasive grinding wheels  should be located symmetrically on the table to ensure that cars and blocks of solid bench , without shaking , trembling phenomenon .
  3 , according to the blocks of length, width , height adjustment limit switch , so that the blade lift and skip the trip in a reliable and effective range. Saw blade before sawing blocks should leave a maximum 10 ~ 20mm. After sawing, saw cut blocks should be left at the bottom of the 20-40mm, blade knife before walking around to run , should make all exit blocks kerf blade distance of not less than 150-200mm, to prevent the blade hit shortage material .
 4 , the test can be carried out after cutting blade idling stability , are not allowed to start the blade edge blade , cutting blades are not allowed to stop the rotation shall be stopped after the exit kerf contact with the blocks .
 5, after cutting blocks if there shaking discovery should immediately stop cutting the blocks to be firmly fixed in order to continue to work , cutting , and are not allowed to move in any blocks .
 6 , when the cutting blade found a significant slowdown or even a folder knife phenomenon , it may be belt slippage , compression nut loose or knife to eat too much depth , the cutting speed is too fast and other reasons, should be timely adjusted .
 7, the line speed should be processed stone hardness and wear resistance to adapt , it is recommended to select the next table line speed cutting different types of stone .
Tip: line speed is not high , an increase in cutting efficiency , reduced life of the blade .
      8 , feed rate , depending on the  GUSHI concrete diamond blades performance of the processing of materials for each material when there is a certain depth of cut is constant feed speed range , if the speed is too high, the diamond will accelerate wear and tear or even fall off , causing the blade consumption too fast, if the speed is too low , then they will make the process of self-sharpening blades can not be normal , so " blunt , slip " out cutting capacity . Under normal circumstances, when you cut the feed rate to slow , sawing should be uniform , typical for common materials when cutting depth is 20mm, recommended feed rate table below for your reference , when the thickness of the cutting speed can change cutting area (cm2/min) to conversion .
   Tip : The first three times before each feed or walking plates should be halved . Common materials blade feed speed unit : mm / mi
9 , the depth of cut stone for medium  GUSHI sanding discs hardness such as marble, limestone cut through at once , for hard and abrasive stone big as granite, sandstone should step cutting, saw cutting monolithic granite , eating knife depth is generally 10-20mm , depth of cut marble cutting tool 50-100mm, multi-chip -sided cutting hard granite , each cutting tool depth of 3-5mm, should be based on the hardness of the stone , using a saw blade and performance may be recommended following efficiency table for your reference. Common materials cutting efficiency Note: " 1 " indicates a low power finishing ; " 2" indicates a high -power roughing.
10 , the rotation direction of the blade in the same direction as the feed stone along the cutting , contrary to the reverse cutting , and when the reverse cutting , because an upward vertical component is formed of stone off potential, and therefore , the solid stone, in the same conditions Next , you should try to use smooth cutting. When using inverse cutting, cutting depth to be reduced , generally reduced to shun cutting 1/3-1/2 .
