Grinding disc damage and preventive measures

High quality metal grinding disc is a widely used grinding tool, usually composed of abrasives, adhesives, and reinforcing material. When in use, the disc can cause high-speed rotation damage to the human body. In order to reduce and control the occurrence of hazards, it is necessary to understand and grasp the hazards expressed and their preventive measures.

 

Fracture accidents and preventive measures

Breaking the high quality metal grinding disc not only causes death or serious injury, but also causes serious damage to the workshop or the casing. Although the manufacturer has taken various precautions, occasional wear or breakage of the grinding disc may occur if care is taken. The application takes the following precautions:

 

  1. Handling and storage

During transportation and handling, if the high quality metal grinding disc bonded with phenolic resin is wet, it will reduce its strength; with ceramic-bonded discs, the temperature is very sensitive to repeated changes; uneven water absorption will make the disc unbalanced. Therefore, when loading and unloading the disc, it must be carefully placed and placed in a dry and cool place to keep the discs in a normal state.

 

  1. Crack inspection

New high quality metal grinding disc should be inspected to ensure that the discs are dry and undamaged. The easy way is to use a raft to illuminate the disc. The complete ceramic disc will give a crisp sound. When combined with an organic bonded grinding disc, it will make a low sound, but the sound produced by the broken high quality metal grinding disc is different. For suspect discs, it should be clear to the supplier.

 

  1. Testing

Before the new high quality metal grinding disc is officially used, it should be tested at full speed and carefully observed. After wet grinding, the discs should be idle for a period of time and the water removed. Otherwise, water will accumulate in the lower part of the disc, causing the high quality metal grinding disc to become unbalanced, causing the next use to burst.
