Stone processing has a long history, since the earth has its own human activities, there has been stone processing, so that archaeologists have divided the age of ancient human life into the Paleolithic and Neolithic age。 In the Paleolithic period of 2。5 million years, stone tools were the main labor tool of mankind。 More than 8 000 years ago, mankind began to grind the stone axe, stone adze, Stone chisel and stone shovel, the grinding disc and the punching of stone hammers, stone pieces, stone tools as the main tool。
Later, with the advent of metal tools, humans gradually mastered a variety of stone mining and processing methods. Stone wool plate processing initially used pendulum sand saw, saw machine frame using rope hanging, feed system by gravity counterweight to complete. The saw blade tensioning mechanism is tensioning by wedge block. Abrasive mainly uses river sand, by artificial sand and add water to complete. Saw the plate size is small, the thickness is not uniform, the surface roughness is very large.
The processing technology is relatively simple, the product is single, the labor intensity is big, the quality is poor. Before the Industrial Revolution, all stone mining and processing was done by hand. It was not until 19th century that the first machinery for the processing of stone appeared in Europe, which brought a revolution to the stone processing industry. After the invention of stone machinery, stone processing was freed from heavy manual labor.
Since then, stone processing began to develop from manual operation to mechanization direction. With the development of stone processing equipment and processing tools, a diamond frame saw machine has appeared, which is used to process the wool sheet of marble waste material. The feed mechanism and tensioning structure are hydraulic, while the saw frame adopts the translation type.
恒彩彩票官网The granite frame sand saw adopts synchronous screw feed structure, the sand adding system adopts automatic mixing sand blasting and water spraying system, and the processing efficiency and processing quality are greatly improved. With the advent of new technologies, stone processing equipment has been continuously developed, and its processing technology has been continuously improved. Stone processing from the plate to the special-shaped development, with the emergence of circular arc plate cutting machine, circular arc plate grinder, stone wire cutter, CNC engraving machine and a series of special-shaped stone processing equipment. Stone processing equipment also with the development of science and technology and constantly improve and update, from simple electrical control to PLC control and CNC direction development. Processing methods also from mechanical processing to high-pressure abrasive water processing, laser processing, flame processing, sand blasting processing and other direction of development.
Auxiliary equipment also from a single mechanical device to CNC and intelligent direction of development. In the 20th century century, the mechanized production and processing equipment of stone was developed rapidly in Germany, France, Spain and other European countries, which promoted the technological progress of stone processing machinery. In the late the 1980s, with the advantage of cheap and high quality, Italy became the developed country of stone machinery manufacturing industry in the world.
After that, Asia's Japan, Taiwan and mainland China also gave birth to a lot of excellent stone equipment enterprises. Since 1980, China's stone machinery manufacturing industry has been the introduction of advanced national technology, has initially formed a complete stone processing machinery manufacturing system, manufacturing technology level and the international advanced level of the gap is rapidly shortening, China is gradually becoming a powerful country of stone machinery manufacturing.
