What is the main purpose of truing a grinding wheel?

To enhance the sharpness of the wheel
To restore the shape of the wheel and make it concentric with its bore
To increase the grit size of the wheel
To change the wheel's grinding angle

The correct answer is: To restore the shape of the wheel and make it concentric with its bore

The main purpose of truing a grinding wheel is to restore its shape and ensure that it is concentric with its bore. Over time and with regular use, grinding wheels can become uneven or develop grooves that affect their performance. Truing helps to remove any irregularities on the surface of the wheel, ensuring that it maintains a uniform shape. This is essential for achieving precise and efficient grinding operations. A true wheel will not only perform better but will also prolong the life of the wheel and enhance the quality of the surface being ground.
