Sandbelt
close Belt grinding is a form of coated abrasive (commonly known as sandpaper, emery cloth) grinding. As early as 1760, the first piece of sandpaper appeared in the world, but it was limited to manual operation at that time. It was not until 1900 to 1910 that the era of mechanical use of abrasive paper and abrasive cloth was entered, and it was first applied to the wood industry in the form of annular belt. This mechanical grinding method using annular belt abrasive cloth is the prototype of abrasive belt grinding. After 1930, abrasive belt grinding gradually developed to metal processing. During the Second World War, the United States took the lead in using abrasive belt grinding in weapon manufacturing and achieved remarkable results. At the beginning of 1950, the emergence of electrostatic sand planting method pushed belt grinding to a new stage, and the application of belt grinding was gradually widespread. Later, Europe and Japan also carried out the research and application of abrasive belt grinding technology, and the abrasive belt grinding technology gradually developed into an independent processing technology field with complete categories and complete technical system.
