Zhengzhou, China (PRWEB) November 12, 2014
With the continuous improvement of modern day machining and the emergence of all sorts of new components as well as the rising demand for machining precision and surface roughness, corresponding sophisticated grinding strategies and abrasives goods, specifically coated abrasives, are establishing towards higher efficiency, longer service life, and super precision. Abrasive belt grinding techniques have stepped into an era of modernized development. Industrial created nations in Europe and America attach fantastic value to the R&D and application of grinding techniques. Even though the abrasive belts’ working life has been improved, the application fields are expanding: abrasives belts can be utilized in wet grinding, dry grinding, high-speed grinding, and higher precision components polishing. The powerful, higher-speed, higher-effective, and precision abrasive belts are not restricted to higher-method coated abrasives products, but far more of products with high added worth. The high quality and regular of abrasive belts is a symbol of a nation’s comprehensive level of coated abrasives and can bring high economic benefits.

Current Scenario of Abrasives Belts

The worldwide developing trend of abrasive belts is speedy. Given that 1960s, the development of electrostatic abrasive grain dispensing and coated abrasives technologies have helped industries developed nations, such as some European nations, America, and Japan, made enormous achievements. With the emergence of special coated abrasives (ceramic abrasives, abrasive compound, grouped abrasives, etc), all varieties of abrasive belts produced of diamond, CBN, zirconia alumina, ceramic abrasives, abrasive compound, and grouped abrasives sprang up. Diamond abrasive belts developed by Japan are successful in processing some supplies of higher hardness, such as monocrystalline silicon wafer. Internationally known brands of abrasive belts contain 3M, Norton, Hermes, VSM, Klingspor, DEER, and so on. Abrasive belt grinders exist in a variety of types. With the development of automation technology, CNC abrasive belt grinder and robot abrasive belt grinding center have been applied.

As a kind of elastic grinding, abrasive belt grinding is a compound method that has the functions of grinding, lapping, and polishing. Considering that the abrasive grains on abrasive belts have a far more potent grinding force than the grinding wheels, the grinding efficiency is really higher in three aspects: removal rate, grinding ratio, and abrasive belt machine tool power availability. Abrasive higher-price grinding has been applied in foreign nations to attain high removal price of metal. So far, the recognized abrasive belt removal rate of steel has exceeded 700cm3/cm•s. Abrasive belt grinding ratio is far beyond the grinding wheels, and abrasive belt machine tool energy availability reached 80% early in the preliminary period. The figure is as higher as 96% presently. For that reason, abrasive belt grinding technique has turn out to be an important approach for industrial developed nations to gain high economic rewards.

Use of Abrasive Belt Grinding

Abrasive belt grinding has formed a full and systematic processing approach soon after 3 decades’ development. It is popular among users thanks to its higher grinding efficiency, wide application fields, strong adaptability, low charges, and simple-to-deal with characteristics. In foreign countries, abrasive belts are capable of processing all kinds of engineering components. Elastic and higher efficiency cold cutting abrasive belts have been extensively used in massive flat thick and thin sheet materials, metal and nonmetal workpieces, complex workpiece forming grinding and polishing, metal tube cylindrical grinding and internal grinding, and so on. Dry grinding disc can replace polishing wheels in polishing approach and be utilized in chip removing and rust removing of massive boxes, ships, and bridges.
