What is the primary function of a blotter on a grinding wheel?

Increase the grinding speed
Protect the flanges from abrasive grit
Adjust the wheel diameter
Limit the use of the wheel

The correct answer is: Protect the flanges from abrasive grit

The primary function of a blotter on a grinding wheel is indeed to protect the flanges from abrasive grit. Blotters serve as protective pads that are placed on either side of a grinding wheel, acting as a barrier between the wheel and the flanges of the grinding machine. This helps to prevent damage to the flanges, which can be caused by abrasive materials that might wear down the contact surfaces. Additionally, blotters help with even distribution of pressure when the wheel is mounted, ensuring a secure fit and reducing the risk of wheel failure during operation. This protection is crucial because maintaining the integrity of the flanges is essential for safe grinding operations and to extend the life of the grinding wheel itself. The other options do not accurately describe the purpose of a blotter. Increasing the grinding speed is related to the specifications of the machine rather than the use of blotters. Adjusting the wheel diameter doesn't pertain to the function of blotters, as the diameter is determined by the wheel itself. Limiting the use of the wheel is more about the operational guidelines than a function served by the blotter. Thus, the choice regarding the protection of flanges clearly defines the key role of the blotter in a grinding operation.
