Diamond Wire Saw R&D and Application

The idea of ​​mining stone with diamond wire saws was proposed by the British D.H. Prowse in 1968. The first utility was developed by Luig Madrigali in Italy in October 1977. In less than a few years, hundreds of saw machines were produced, and more than 200 stone quarries in Italy promoted the use of wire saws. As a result, diamond bead wire saws were first used in Italy and were called the “Revolution of Marble Mining”. At the S. Ambrose1o stone fair in Italy ERONA in 1969-1970, beaded ropes and processing equipment with electroplated beads were exhibited for the first time.
Since then, this highly promising tool has been rapidly developed. After 20 years of research and development, diamond wire saws are not only widely used in the mining of marble, but also used in the separation and cutting of hard rocks such as sandstone and granite; not only for open pit mining, but also for underground narrow veins and explosions. The exploitation of dangerous South African underground gold mines; not only for the processing of special-shaped stone products, but also for the construction and the construction of road works and the removal and repair of reinforced concrete.
The creative use of gangue string bead saws in gangue and construction projects, making diamond bead wire saws from gangue yards to stone processing plants, cutting from large blocks to trimming, cutting from plates to special-shaped products, and processing in construction projects More and more applications.
As the third generation product in the development of diamond tools, diamond wire saw has been widely used in various projects after more than 20 years of research and development and improvement. This is mainly because it has the following advantages
1) The equipment is simple, easy to install, free from space and space limitations, can be horizontal, vertical and oblique cutting, sawing area of ​​up to 200m2, good processing quality, low stone loss, cutting speed, noise and vibration Good working environment, strong adaptability, can choose different specifications and sizes of diamond wire saw equipment according to the cutting object and working conditions
(2) Significantly increase the rate of raw materials used for stone reclaiming and protect precious stone resources.
3) Can process various shapes of granite and marble shaped products, its high added value, can significantly increase economic efficiency
4) Large-size large blocks of blocks can be mined to increase the specifications of finished materials, thereby increasing the product specifications of advanced stone processing equipment, and improving cutting efficiency and economic efficiency.
5) The superiority of the above-mentioned diamond bead wire saw is undoubtedly a solution to the shortfall in the stone material industry in China, which is caused by the shortage of large-size sheets, and the irregular products are full of contradictions at home and abroad and can be greatly promoted. Actively developing and promoting rope saws is an important part of the development of China's stone industry
Since the advent of diamond wire saws, it has been a process of continuous innovation in the manufacturing process of wire saws, and it is also the continuous development and application of wire saws. At present, there are more than 2,000 wire saws in the world, and more than 1,000 wire saws in granite. There is an increasing number of block cutters and wire saws, and as many as 50 to 100 wire saws are available. It is used for the repair and maintenance of buildings, and the use of wire saws for the reconstruction of traffic projects is increasing. Research shows that diamond beading is still a major factor in the cost and effectiveness of diamond wire saw cutting. Therefore, a series of innovations have been made around the bead manufacturing process at home and abroad.
1). Beads form a variety of plating products, sintering and high-temperature brazing products
2).KPV218, WPD20 cold press significantly raises the production efficiency of beaded cold pressing, and the domestic manual cold pressing process is also continuously improved.
