Diamond wire saw technology is a high-tech content of technology, but also an advanced processing technology. From the current status of the development of the application of wire saws can be seen, the technology itself, in terms of the beads will be small diameter direction of development, not only can save processing materials and can save processing energy.
The use of brazing technology to make diamond beaded rope is also the focus of future technological development. Brazing technology can improve the holding power of solder on diamond, thus solving the problems of serious abnormal shedding of diamond abrasive and low utilization rate brought about by the poor holding of diamond abrasive grains by the matrix under the traditional production process method, which is expected to improve the cutting performance of beads again.
Stone mining using wire saw mining mine with mine space geomorphology adaptability, small cutting slit, sawing speed, barren material size, etc., can completely avoid the traditional blasting, flaming and other mining methods brought about by the waste of resources, noise, pollution, energy consumption and other shortcomings, to achieve high efficiency, environmental protection and energy saving of green mining.
The following is a brief introduction to the wire saw technology in the stone mining applications
(1)Marble mining
wire saws are the main mining equipment for soft marble mines. In some of the mining technology of marble mines, but also the use of wire saws and chain split saws (or chain split diamond band saw cutting machine) combination of mining methods. Chain-splitting equipment is mainly used to cut separation surfaces that cannot be easily or inefficiently cut by wire saws, such as the vertical back and horizontal bottom surfaces where the separating blocks are connected to the ore body, in order to comprehensively improve the mining efficiency, and it is the current technological combination of the mining of separating marble.
(2)معدن گرانیت
Taking into account the performance of wire saws can achieve and mining comprehensive cost, in the mining of granite mines, wire saws are generally only used in the granite separation block and the ore body connected to one or two vertical side of the cutting, while the granite separation block and the ore body connected to the back of the vertical surface and the horizontal underside, is still relying on the combination of row of holes rock drilling and control of the blasting method for separation.
(3) Stone material shaping
Stone barren material shaping is usually done in the mine or processing plant. The use of wire saws can be shaping large barren material, but from the perspective of wire saw performance and processing costs, is also mainly used for marble mine barren material shaping. For granite barren material, the use of wire saws for shaping is generally rare.
(4) Slab cutting
Plate cutting is a process in the stone processing industry. Usually cut with diamond circular saw blades, but the plate size is relatively small. Single wire saws can be large plates and oversized plate cutting, and the thickness is not limited, but with the installation of dozens of hundreds of saw blades compared to the frame saw machine, the total cutting efficiency is low and high processing costs, so a single wire saws are often used to cut very thick plates or small quantities of different thicknesses of large plates. In recent years, the newly developed multi-rope side-by-side bead cutting technology (also known as combined wire saw cutting technology), in the same saw machine, as long as the replacement of different uses of the bead rope, change the wire saw line speed, you can conveniently cut marble or granite slabs, by adjusting the spacing of the wire saws, you can flexibly change the thickness of the finished plate, with the advantages of the framework of the saw machine can not be compared, so the multi-rope side-by-side wire saw cutting technology is a very Therefore, multi-rope side-by-side wire saw cutting technology is a very promising large plate cutting technology.
(5) Shaped stone products processing
wire saw processing shaped stone is currently one of the high technology content of CNC stone processing technology, although only nearly 15 years of development history, but has become a high value-added shaped stone products processing of the main equipment. In addition to the common wire saw shaped stone sawing equipment, there are some small desktop bead saw machine, specializing in the processing of parquet, curved edges and other shaped stone products.
