Diamond bead wire saw technology is a high-tech technology and an advanced processing technology. It can be seen from the current development of the application of the bead wire saw that, in terms of the technology itself, it will develop toward the small diameter of the bead, which can save processing materials and save processing energy. The use of brazing to make diamond beads is also the focus of future technological development. The brazing technology can improve the holding force of the solder on the diamond, thereby solving the problems of the abnormally falling off of the diamond abrasive due to the weak holding of the diamond abrasive grains by the substrate in the conventional manufacturing process, and the utilization rate is low, and it is expected to improve the beading again. Cutting performance.
The use of 
beaded wire saws for stone mining has the advantages of strong adaptability of mining space and geomorphology, small slits, fast sawing speed and large size of blocks. It can completely avoid the waste of resources caused by traditional mining methods such as blasting and burning. , noise, pollution, energy consumption and other shortcomings, to achieve efficient and environmentally friendly energy-saving green mining. Simple introduction of stone net Jing'an is the application of bead wire saw technology in stone mining
1 marble mining
Beaded wire saws are the main mining equipment for marble soft mines. In some mining-leading marble mines, a combination of bead wire saws and chain saws (or chain-type diamond band saw cutters) is also used. The chain type equipment is mainly used for cutting the separation surface of the bead wire saw which is inconvenient to cut or cut very low efficiency. For example, the vertical back surface and the horizontal bottom surface of the separation block and the ore body are combined to improve the mining efficiency, which is the optimization of the current mining and separating marble. Technology portfolio.
2 granite mining
Considering the best performance and comprehensive mining cost currently achieved by bead wire saws, bead wire saws are generally only used for cutting one or two vertical sides of a granite separation block connected to an ore body when mining a granite mine. The vertical back surface and horizontal bottom surface of the granite separation block and the ore body are still separated by the combination of the hole drilling and the controlled blasting.
(2) Stone block shaping
The shaping of stone blocks is usually done in mines or processing plants. The beaded wire saw can be used to shape large blocks, but from the perspective of bead wire saw performance and processing cost, it is currently mainly used for the shaping of marble mine blocks. For granite blocks, it is rare to use a bead wire saw for shaping.
(3) sheet cutting
Sheet cutting is one of the largest processes in the stone processing industry. Cutting is usually done with a diamond circular saw blade, but the sheet size is relatively small. Single bead wire saw can cut large plates and oversized plates with unlimited thickness, but compared with frame saws with dozens of hundreds of saw blades, the total cutting efficiency is low and the processing cost is high, so single rope Saws are most commonly used to cut very thick sheets or small batches of large sheets of varying thickness. In recent years, the new multi-rope side-by-side bead cutting technology (also known as combined wire saw cutting technology) has been newly developed. On the same sawing machine, it is easy to cut marble or flower by changing the bead string for different purposes and changing the speed of the bead wire saw. Granite slabs, by adjusting the spacing of beaded wire saws, can flexibly change the thickness of finished plates, which has the advantage that frame sawing machines can't match. Therefore, multi-rope side-by-side bead wire saw cutting technology is a promising large-scale plate cutting. technology.
(4) Processing of special-shaped stone products
Beaded wire sawing processing of shaped stone is one of the most technically advanced CNC stone processing technologies. Although it has only been developed for nearly 15 years, it has become the main equipment for processing high value-added shaped stone products. In addition to the common bead wire sawing shaped stone sawing equipment, there are also some small desktop bead saws, which are specially used for processing shaped stone products such as parquet and curved edges.
