Features and applications of sanding belts

In conventional coated abrasive grinding, the abrasive particles are uniformly distributed on the surface of the substrate in a single layer. Uniform particle size is an important factor for efficient and cold grinding of coated abrasives. The typical difference between sanding belt and grinding wheels is that the former operates by improving grinding stress rather than by increasing the belt speed. The linear speed of the abrasive belt is usually between 15m/s-35m/s. At present, coated abrasives are developing in the direction of special purpose, high precision and high efficiency, and have the characteristics of high-speed, strong and heavy-duty grinding. To date, coated abrasives such as sanding disc ,belt and velcro sanding paper has been used in the automotive industry, shipbuilding industry and tool manufacturing.

There are advantages of sanding belt grinding: First of all, it can solve large area grinding and complex surface grinding that other abrasive products cannot solve. In addition to the materials that can be processed with grinding wheels, abrasive belt grinding can also process non-ferrous metals such as copper and aluminum, as well as non-metallic soft materials such as wood, leather, and plastic. The "cold" grinding effect during processing of heat-resistant and different abrasive materials makes belt grinding even more unique. Secondly, the sanding belt’s efficiency is high, the heat storage is small, and the workpiece is not easy to burn. The high-quality abrasive belt is reflected in the small surface roughness and no small flaws on the surface. Besides, belt grinding equipment is simple and safe to operate with low noise and dust. Due to the light weight of the belt, it is easier to control the balance than the wheel. In addition, the flexible grinding effect of the abrasive belt can greatly reduce vibration and shock. What’s more, belt grinding has low power consumption, energy saving and environmental protection. The higher the belt grinding force, the higher the power availability and grinding efficiency of the machine.
