Stone processing equipment includes sawing and processing equipment, grinding and polishing equipment, and special-shaped processing equipment. Stone equipment follows the whole stone industry and flourishes together, but China's stone industry is still an emerging industry. There are still some shortcomings in stone processing equipment and its application. There is still a gap between the international advanced level and the status quo. Recognize clearly, and also have a prospect for the development of stone processing equipment. First, sawing processing equipment The diamond frame and granite sand saw used in the domestic stone industry are mainly imported from Italy. After entering the twentieth century, several companies in China have begun to digest and absorb the technology of Italian large-scale processing equipment, producing domestic frameworks and granite sand saws, but because of the lack of mastery of key technologies, work efficiency, cutting costs and continuous There is still a big gap between the operation of the fault and the Italian equipment. Guangdong Lida, Fujian Shengda, Guangdong Keda, Jinan Hengyunda and other enterprises all produce frame data and sand saws. Shanghai Feizhou Company introduced the granite sand saw produced by the Italian BM company with good quality and performance, and has a high market share in the domestic market. The marble gang saw is widely used in China, and the domestic equipment is relatively mature. There are many problems when the saw frame rail system and the hydraulic tensioning system are faulty. The Italian equipment is mainly double-link, and the domestic equipment is single-link. the Lord. The application of granite sand saw in the domestic stone industry is poor. Except for a few large enterprises and foreign-funded enterprises, the sand saws of most enterprises are basically in a state of suspension. The main reason is the lack of operation management of sand saw cutting work in China. Experience, especially the mortar ingredients and slurry supply system of sand saws, there is still a big gap compared with Italian stone enterprises. Second, grinding and polishing equipment At present, the hand-held mill and the multi-head continuous grinding and polishing machine are the most widely used. At present, the hand-held grinding machine is mainly used for grinding and polishing of shaped plates. The multi-head continuous grinding and polishing machine is a new type of advanced grinding and polishing equipment, which has been widely used in the processing of ordinary flat plates at home and abroad, especially the processing of large-area facing plates. The domestic continuous grinding and polishing production line has been widely used by domestic stone enterprises in recent years. For example, the continuous grinding and polishing machine produced by Guangdong Keda, Fujian Shengda, Guangdong Hesheng and other enterprises is also widely used in the domestic stone processing industry. Shandong Huaxing has Developed a continuous grinding and polishing production line and sold it to Vietnam, Kazakhstan and other countries last year. Stone polishing technology has also been continuously developed. In recent years, resin abrasive tools have also widely replaced diamond bitum abrasives, and diamond abrasive tools have also been widely used. The main development direction of stone polishing equipment is to adopt new electrical control technology to integrate light, liquid and electricity. Nowadays, the grinding and polishing thickness of the large-plate grinding and polishing equipment is getting thinner and thinner, and the wide-faced thin-plate grinding and polishing technology will be applied. The localization technology level of stone grinding and polishing equipment is shrinking with the advanced technology of Italy. With the continuous improvement of the manufacturing and design level of stone equipment manufacturers, domestic grinding and polishing equipment will catch up with Italy. Third, special-shaped processing equipment Currently. There are dozens of domestic stone shaped processing equipment, but compared with advanced equipment such as Italy, there is still a big gap. A few large-scale stone processing enterprises in China have introduced CNC special-shaped processing equipment from Italy in recent years to carry out complex special-shaped stone processing. The imported special-shaped processing equipment mainly includes stone processing center, horizontal CNC machining machine, vertical CNC machining machine and CNC table top processing. Machine tools, etc. Stone profile processing has many processes, even for large enterprises, it is done by hand, especially the grinding of irregularly shaped surfaces, which is basically done by hand. Although there are many varieties of domestic special-shaped processing equipment, there are no CNC machines with strong functions. The development of special-shaped stone processing equipment is relatively large. The main direction is multi-dimensional numerical control, equipment grinding and polishing technology of special-shaped stone, processing equipment and tools of various complex space surfaces, and can refer to the structure and control technology of metal numerical control processing equipment for stone. Shaped processing equipment. The technology of stone plane shaped processing equipment is mature, and the CNC diamond bead wire saw, CNC waterjet cutting machine, 3D CNC milling machine and other special-shaped processing equipment have matured and are widely used in stone processing. The cutting and grinding and polishing technology of arc stone and spherical stone is relatively mature. Shaped edging equipment (especially various arc edges) has been continuously introduced to the market in recent years, and has achieved continuous grinding and polishing of multiple ends, and the level of equipment has been continuously improved. Fourth, the development trend of domestic stone equipment From the development of foreign stone equipment in recent years and its application in the domestic stone industry, the current development trend of domestic stone equipment is mainly reflected in three aspects: 1. The development of stone equipment to high efficiency, such as the increase in the number of saw blades; 2. The development of stone equipment to automation, such as the extensive use of numerical control technology in stone processing equipment; 3, stone equipment to environmental development, such as diamond bead wire saw, high-pressure water jet and other environmentally friendly processing equipment development and application. It can be foreseen that with the advancement of stone processing technology and equipment, stone processing enterprises will develop towards the direction of factoryization, management informationization, high quality and low consumption, and high efficiency and automation are still the eternal theme of stone equipment development! Realistic pen and ink painting is a pen and ink painting creation using realistic techniques, which is essentially different from all previous pen and ink paintings. In the past, there were signs that one kind of "work" served another kind of "work". The nature of its existence seemed to have no independence "forever". Even if some works had strong independence, they could not get rid of the fate of "attachment". Realistic pen and ink painting is different. It is independent. Its existence has no "dependency". Its existence itself is its ultimate result. Pen Sketch,Sketch Pen Drawing,Black Pen Sketch Drawing,Pen Sketch Drawing The universe in the stone is great , https://www.zdsarts.com
