Wire saw is not only used for stone mining, but also widely used in stone processing. For example, diamond wire trimming machines used in stone processing factory, CNC diamond wire saw machine for processing special-shaped stone products, and single-rope and multi-rope diamond wire saw machine for processing slab products, etc.. It is necessary to trim stone blocks. Especially in the mine directly to complete the trimming of the blocks . Its advantages are reflected in the regular size of the blocks after trimming, good square, and the gross volume of the blocks is very close to the actual block volume after acceptance. Because the freight of block is calculated according to its weight, the gross square volume is closer to the real square volume, the less block will be, therefore, the transportation cost of the useless parts on the blocks is also reduced. Many domestic stone mines are located in the inland and western regions, 1000-2000 kilometers away from coastal ports or stone developed areas, some even reach 3500 kilometers, the freight cost of blocks is 3-4 times higher than the mining cost, and some are even as high as 6-8 times. If the blocks are not trimming, the freight generated by the useless part of the blocks will occupy a considerable part of the total cost of the blocks. Save this part cost, to raise stone material economic benefit, reduce block price, improve product market competitiveness is of practical significance. Therefore, it is suggested that in the stage of stone mining, the trimming of blocks should be completed. Another point of trimming blocks is reflecting in panel processing, especially slab processing. The flat block top surface can save the cutting time of sand saw or row saw.
