What should be the minimum size of flanges used with a grinding wheel?

1/4 the diameter of the wheel
1/3 the diameter of the wheel
1/2 the diameter of the wheel
The same as the diameter of the wheel

The correct answer is: 1/3 the diameter of the wheel

The minimum size of flanges used with a grinding wheel should be at least 1/3 the diameter of the wheel. This specification ensures that the grinding wheel is properly supported and secured during operation, which reduces the risk of vibration and uneven wear that can lead to wheel breakage. Flanges play a critical role in stabilizing and centering the grinding wheel on the spindle, allowing for effective grinding performance and enhancing safety. When the flanges are too small, they may not provide sufficient support, which can compromise the integrity of the wheel and increase the likelihood of accidents. Using flanges that are at least 1/3 the diameter of the grinding wheel strikes a balance between effective support and operational efficiency, following industry standards for safety and performance.
