The marble plate is popular with consumers because of having natural and beautiful textures, and is mainly widely applied to walls, columns, floors, window boards, service desks and the like of public building projects such as squares, libraries, supermarkets, airports, cinemas, hotels and the like; the current market has three ways for processing marble plates, namely cutting by a diamond circular saw, a diamond frame saw blade and a diamond rope saw; the diamond circular saw has the advantages of wide processing range, high processing efficiency, simple operation, small investment and the like, but the processing size of the diamond circular saw is limited, the processing size of the diamond circular saw can only reach 30-35% of the diameter of the circular disc, the larger the diameter is, the thicker the corresponding thickness is, the larger the saw machine is, the processing technology of the diamond circular saw blade with the diameter of more than 2200mm is complex, the precision is difficult to control, and the yield is low; secondly, the diamond wire saw is used for processing the stone, so that the processing of a large marble plate is met, but the wire saw technology at home and abroad is not completely mature, the multi-wire tensioning and positioning structure is complex, the rigidity and the service life are low, the price is high, the diameter of the stone string bead is about 12mm, the diameter of the minimum stone string bead prepared by manufacturers and research institutes can be controlled to be about 6mm, the saw kerf is wide during processing, and the application of the diamond wire saw on the granite large plate is limited to a certain extent; finally, the diamond frame saw blade is combined with the two processing modes, the diamond frame saw blade is not influenced by the outer diameter, has the advantages of thin thickness and the like, the general thickness is between 1.8 and 3.5mm, the loading amount can reach between 25 and 150, the cutting seam is narrow, the yield is high, the quantity of plates processed at one time is large, the processing breadth is not limited, the processing efficiency and the quality are high, and the workload of subsequent grinding and polishing is reduced, so that the diamond frame saw blade is widely applied to the marble cutting industry, and according to preliminary statistics, the frame saw blade has the quantity of about 4500 in places such as Fujian Yunfao, fujian Quanzhou, jiangsu, chongqing, shanghai, beijing, hubei and the like in China, and is applied to artificial marble, natural marble, soft (low-hardness) granite, artificial granite and the like at present, relatively mature.
The minimum thickness that can accomplish 1.8mm of frame saw blade base member on the market at present, because saw blade base member thickness is less, the outturn rate of panel is higher, and to the cutting of high-end stone material, with the cutting of thinner frame saw blade base member, economic benefits is higher. With the increasing price and production cost of stone raw materials to be processed, the thickness of 1.8mm can not meet the requirement, a thinner frame saw blade base body is urgently needed, but the rigidity and the impact resistance of the thinned frame saw blade base body can not meet the requirement, and the frame saw blade base body with smaller thickness can not be produced by the traditional production method at present.
