Check the bearing temperature frequently. If the temperature is too high, check whether the lubrication and transmission parts are normal and whether the rolling distance is too tight. Find out the cause in time, take corresponding measures, and stop the machine for inspection when the situation is serious. Check the tightness of the transmission belt frequently. Losing the belt will reduce the transmission efficiency and affect the grinding effect. Too tight will easily cause the bearing to heat up, increase power consumption and reduce the service life of the transmission belt. Various transmission parts must be fastened and reliable, special tools should be used for disassembly or installation, and direct hitting with tools such as hand hammers is prohibited. Always check the pneumatic components in the air circuit, air circuit, and connections for air leakage or damage. At the same time, check whether the air supply pressure meets the requirements. The use of the timing belt should also be checked frequently. If it is found to be too tight, too loose, jumping, running off, or seriously worn, it should be adjusted, repaired, or replaced in time.
