​Maintenance and Replacement of Grinding Discs on Double Disc Grinding Machines

As one of the core components of double disc grinding machine, the maintenance and replacement of grinding discs are directly related to the performance, processing accuracy and service life of the machine. Therefore, careful maintenance and timely replacement of the grinding disc is the cornerstone to ensure the efficient and stable operation of the grinding machine.

In daily maintenance, the first task is to keep the grinding disc clean. Grinding chips, dust and oil remaining on the surface of the grinding disc should be removed immediately after each operation. These impurities not only affect the grinding efficiency, but also may accelerate the wear of the grinding disc. When cleaning, a soft cloth or special brush should be used, avoiding the use of metal scrapers and other hard objects, so as not to scratch the surface of the grinding disc, affecting its grinding effect and life.

Coolant plays a vital role in the grinding process, which not only cools the grinding disc and workpiece, but also reduces friction and wear and improves grinding efficiency. Therefore, coolant management is also an important part of grinding disc maintenance. The concentration and pH value of the coolant should be checked regularly to ensure that it is in the best condition. At the same time, the adequacy of the coolant needs to be ensured to avoid overheating and accelerated wear of the disc caused by dry grinding.

In addition to daily cleaning and coolant management, the wear of the discs should also be checked regularly. Usually, professional measuring tools are used to assess the flatness and wear of the discs. Once serious wear, cracks or unevenness are found on the surface of the grinding disc, it should be replaced in time so as not to affect the machining accuracy and workpiece quality. Wear of the grinding disc not only reduces the grinding efficiency, but also may cause damage to the workpiece, therefore, regular replacement of the grinding disc is the key to ensure the machining quality.

When replacing the grinding discs, certain operating procedures need to be followed. Firstly, switch off the power supply of the double disc grinding machine to ensure that the equipment is in a safe state. Then, loosen the bolts connecting the grinding disc with the spindle or flange, and remove the old grinding disc from the equipment. After removing the old grinding disc, clean the connection surface of the spindle or flange to ensure that it is free of impurities and oil. Next, install the new grinding disc onto the spindle or flange and tighten the connecting bolts. During the installation process, it should be ensured that the connection between the grinding disc and the spindle or flange is tight and free of looseness to ensure the stability of grinding. Finally, use professional tools to test the flatness of the new grinding disc to ensure that it is within the specified range. After replacement, it is also necessary to carry out test grinding to verify the grinding effect and processing accuracy of the new grinding disc.

In conclusion, the maintenance and replacement of grinding discs on double disc grinding machines is a meticulous and systematic process. Through daily cleaning, coolant management, regular wear detection and standardised replacement procedures, it can be ensured that the grinding discs are always in the best condition, thus prolonging the service life of the grinding machine and improving machining accuracy and efficiency.
