With the continuous improvement of people's living standard, stone has already entered ordinary people's homes.Stone is widely used in architectural decoration, such as surface decoration of ground paving, cabinets and furniture. Secondly, construction stone, including garden, engineering stone; Then it is stone carving, stone artwork, tombstone products and so on. Japanese tombstone basically is our country.In the past 20 or 30 years, the international stone industry has developed rapidly.Since 1990, the global stone production and trade volume have increased by 7.3% and 9.2% annually respectively, higher than other industries. The development of the whole stone industry is obviously faster than the development of the global economy. Chinese stone material production are mainly distributed in the south of fujian province, guangdong province, in eastern shandong province three big stone production province, fujian and shandong province as raw material and processing production, and guangdong is mainly engaged in into/stone material processing, the above three provinces accounted for 85% of the Chinese stone material production production, mainly marble and granite products.

But what relation does stone material have with macromolecule? Just as gelatin is used in ink as a binder, the rough, fine and polished abrasive of stone is made by gluing diamond powder together with thermosetting resin.

The essence of stone grinding is under the action of manpower or mechanical force, the rotary disc to stone continuously vertical feed, both in the contact area mutual friction, wear, the concave and convex surface of the plate surface layer gradually ground. Because granite kind of rock is more hard commonly, the hardness of abrasive tool must exceed the hardness of stone material. Generally, six sets of grinding tools are used to complete the grinding and polishing process. The first two grinding tools should be forced to position grinding, leveling and control the thickness of the plate; The abrasive tools at the back are respectively coarse grinding, fine grinding, grinding and polishing.
