The grinding wheel heats up quickly and the grinding wheel cracks and falls apart.
Jul 17,2026
1. Causes
Continuous grinding under heavy pressure for a long time causes friction heat to accumulate and high temperature to soften the resin bond of the grinding wheel;
The grinding wheel speed exceeds the rated upper limit of the equipment, and the centrifugal force causes cracks;
The grinding wheel aperture does not match the rotating shaft, the clamp is loose, and high-speed rotation causes eccentric vibration;
The grinding wheel is exposed to moisture, has been damaged due to storage, and has cracks, and the upper machine can directly break apart due to stress;
The single grinding feed amount is large, the local instantaneous high temperature causes stress concentration and cracking.
2. Corresponding solutions
Control the grinding rhythm, stop the machine to dissipate heat after grinding 3-5 teeth, and prohibit continuous and long-term heavy grinding;
Check the rated speed of the equipment and the grinding wheel. The equipment speed must not exceed the maximum safe speed marked on the grinding wheel;
Fix the fixture during installation and use grinding wheels with matching aperture to eliminate eccentric vibration;
Store the grinding wheel in a dry and dark place. Check the edges and surface for cracks before use. If there is any damage, discard it directly.
When grinding, feed lightly and grind the saw teeth in stages to avoid sudden heat caused by too deep a single cut;
If the grinding wheel becomes hot and sand falls off the edge, stop the machine immediately and replace it with a new grinding wheel to prevent safety accidents.
