Abrasive belts are a form of coated abrasive (commonly known as sandpaper or sand cloth) grinding, which first appeared in 1760, but was limited to manual operation only at the time. It wasn't until 1900-1910 that sandpaper and sand cloth were first used in machinery, and were first applied to the wood industry in a circular belt form. This use of circular belt sand cloth in machinery grinding is the precursor to abrasive belt grinding. In the 1930s, abrasive belt grinding gradually developed into metal processing, and during the Second World War, the United States were the first to use abrasive belts in weapon manufacturing, and achieved significant results. In the early 1950s, the emergence of electrostatic sand planting methods brought abrasive belt grinding into a new stage, and abrasive belt grinding applications gradually became widespread. Europe and Japan also subsequently carried out research and application of abrasive belt grinding technology, turning abrasive belt grinding technology into a completetechnology system in the independent processing technology field.
Abrasive belts are a type of belt-shaped tool made of flexible materials such as paper and fabric in which abrasives are bonded to the substrate using a binder. It is one of the main forms of coated abrasives. Its basic composition is: substrate, abrasive and binder, collectively referred to as the three elements of the abrasive belt composition.
Modern belt polishing machines fully demonstrate the best combination of motor power, machine tool design, and contact between the sanding wheel and the abrasive belt. Abrasive belt polishing is a very economical method of removing burrs, cutting edges, and surface treatment. The use of high-power motors, durable structures, and suitable abrasive belts can achieve safe and reasonable operation even under heavy load. Modern abrasive belt polishing machines perform exceptionally well due to optimization of the motor power, equipment structure, grinding wheel, and abrasive belt.
As abrasive belt and other technologies continue to develop, abrasive belt polishing has become irreplaceable in the metal processing industry. With advanced abrasive belt polishing equipment, tasks such as surface polishing, circular polishing, trimming polishing, grinding, radius polishing, chamfering, and burr removal can be completed perfectly. Using modular design can improve equipment flexibility and reduce costs.
Mass-production companies have high requirements for the flexibility of their equipment. Using modular technology solutions can reduce production costs and save storage space in the production workshop. If only components needed for each processing step are added to the basic equipment, the return on investment of the equipment will also be very high.
