What are the main advantages of abrasive belt grinding?
Feature 1: simple abrasive belt grinding equipment. Compared with grinding wheel grinder, abrasive belt grinder is much simpler, mainly because the abrasive belt has light weight, small grinding force and small vibration during grinding, and the rigidity and strength of the machine are far lower than that of the grinding wheel grinder.
Feature 2: abrasive belt grinding operation is simple, less auxiliary time. Whether manual or motorized belt grinding, the operation is very simple. This can be done in a very short time, from replacing the adjustment sand to the clamping of the workpiece to be processed.
Features 3: abrasive belt grinding ratio, high power utilization, high cutting efficiency. It can reduce the cost of tools and energy used to remove materials of the same weight or volume and take up less time.
Features 4: abrasive belt grinding is very safe, noise and dust, and easy to control, good environmental benefits. Because the belt itself is light, there is no danger of injury if it breaks. Sand belt grinding is not as serious as grinding wheel desamination, especially when dry grinding, the grinding debris mainly consists of the material of the processed workpiece, it is easy to recover and control the dust.Due to the use of rubber contact wheel, abrasive belt grinding will not form rigid impact on the workpiece like the grinding wheel, so the processing noise is very small, usually <70dB.
After the production of the belt can not be dressed after blunt, often need to replace, large consumption. Since the 1970s, belt grinding has been developing towards large scale and high efficiency.The cutting speed of the abrasive belt has reached 40 m/s, the grinding pressure is 100 ~ 200 mpa, and the material removal amount per minute can reach more than 500 cm.
