The stone industry application of diamond wire saw cutting status and problems

　  With the central government to implement resource conservation, sustainable development, circular economy strategy of deepening, China stone mining eliminate waste, improve material rate, the promotion of advanced mining methods and mining equipment in recent years, the stone industry becomes an urgent need to address the problem. And the voice of the highest is in our country to promote a comprehensive application of the rope saw mining mines, since 2005, the quiet years of the Chinese stone mines mining machinery industry with great breakthrough, the most prominent is the localization of diamond wire saw. The emergence of this phenomenon indicates that the era has come to represent the popularity of Chinese stone mining diamond wire saw machine has come, this will give the level of China's stone mining to improve the level of revolutionary progress.

With the central government to implement resource conservation, sustainable development, circular economy strategy of deepening, China stone mining eliminate waste, improve material rate, the promotion of advanced mining methods and mining equipment in recent years, the stone industry becomes an urgent need to address the problem. And the voice of the highest is in our country to promote a comprehensive application of diamond wire saw mining mines, since 2005, the quiet years of the Chinese stone mines mining machinery industry with great breakthrough, the most prominent is the localization of diamond wire saw. Almost at the same time, the Shanghai Morgan, high stone mining machinery, Henan almt Whirwind, weapon in Quanzhou, Fuzhou skystone diamond etc. several enterprises launched their own diamond wire saw machine, plus the original R & D earlier Guangdong Bureau of Geology and mineral resources prospecting machinery factory and other enterprises, diamond wire saw machine market competition to suddenly become intense. The emergence of this phenomenon indicates that the era has come to represent the popularity of Chinese stone mining diamond wire saw machine has come, this will give the level of China's stone mining to improve the level of revolutionary progress.

The application of diamond wire saw has more than thirty years of history in foreign countries, the early wire saw is only used for cutting soft stone. For the hard granite stone, after wire saw, beaded rope manufacturers and mining enterprises long-term unremitting efforts, with a rope saw mining granite technology more and more mature, the wire saw can be widely used in granite, sandstone and other various hardness of stone mining, product quality is getting higher and higher, costs are lower, in the world has become a trend.

Compared with the traditional "blasting + flame cutting" mining method, the advantages of using the rope saw to the stone mine exploitation are the following advantages:

1 wide adaptability, wire saw is suitable for all types of mines, and flame cutting is only suitable for high quartz content, fewer cracks in the granite mine.

2 strong function, high efficiency, first mining depth, can reach l0~20m or even deeper, flame cutting is generally within the 10m; secondly, cutting speed, generally can reach 3~4m2/h, is 2~3 times of flame cutting.

3 wire saw can be vertical, horizontal, inclined plane and other direction of cutting, but also blind cut, and flame cutting can only be carried out on the vertical cutting.

4. The rate of finished products is high, the comprehensive cost low, first wire saw cut is very smooth and not of the blocks caused any internal injury, second zigzag small, only about 11mm, will not cause waste of resources; and flame cutting section is rough and of the blocks caused some internal injuries, and the kerf, generally for 100 ~ 300mm, resulting in a great waste of resources and production cost is high.

5. Safety and environmental protection, rope saw mining without noise and dust, does not affect the nearby residents and other assignments, and automation degree high, separated operation, low labor intensity of workers, high safety; and flame cutting noise and dust are very large, serious impact on nearby residents and other workers, and workers' labor intensity big, security is relatively low. In summary, in the growing shortage of resources, the surge in oil prices today, with a rope saw granite mining has a significant economic and social benefits.

Control of diamond wire saw factors of production, application while using diamond wire saw mining traditional mining methods can not match advantage, but in actual production application model of diamond wire saw is a series of technical difficulties, including the high cutting efficiency, long life, low price and high reliability. Diamond wire saw is a kind of fragile and easily damaged system. As a ring chain, it is necessary to strengthen the weakest link. The reliability of diamond wire saw is a great problem. Rope saw damage will result in the failure of the entire tool, or make its life expectancy significantly reduced, which has a great impact on the design of the tool and the production of diamond wire saw.

Diamond wire saw production has not yet been a lot of diamond tool manufacturers to master. On the one hand, this is because the diamond wire saw blade production than simple production is more complex. On the other hand, the production of a suitable saw cut natural stone material need diamond wire saw manufacturers and end users of the close cooperation and cooperation. With the diamond wire saw Association of a variety of factors, including: beaded saw cutting life and strings of beads sawing speed and string of beads spacing on the rope saw, mold design, under the normal working condition of wire rope life the various technical difficulties.
