The replacement of a brown aluminum oxide grinding wheel should follow proper safety regulations to ensure stable grinding performance and avoid accidents. During use and replacement, operators should mainly pay attention to wear conditions, validity period, and crack inspection.
Wear Problems
Every brown aluminum oxide grinding wheel has its own wear limit. Excessive use in order to save materials is unsafe and may affect grinding quality.
Generally, the brown aluminum oxide grinding wheel should be replaced when its diameter is worn to about 10 mm larger than the chuck diameter. Timely replacement helps maintain stable operation and improves work efficiency.
Validity Period
A newly taken-out brown aluminum oxide grinding wheel is not always guaranteed to be fully qualified. Grinding wheels have a certain storage validity period, especially resin bond and rubber bond products.
According to regulations, if a grinding wheel has been stored for more than one year, it should pass a rotation test before use. Proper storage in a dry and ventilated place can also help maintain the performance of the brown aluminum oxide grinding wheel.
Crack Inspection
Before installation, operators should carefully check whether the brown aluminum oxide grinding wheel has cracks or damaged areas on the surface. If any defect is found, the grinding wheel should be replaced immediately.
During installation, the spindle speed must match the rated speed of the brown aluminum oxide grinding wheel to ensure safe operation and reduce vibration.
