Truing a grinding wheel is essential for ensuring that it operates at peak efficiency, and the primary benefit is the improvement of its shape and concentricity. When a grinding wheel becomes irregular due to wear, it can lead to uneven grinding, which can affect the quality of the finished workpiece. By truing the wheel, you restore its flat surface and ensure that it is perfectly round, allowing for more consistent contact with the material being ground.

The process of truing essentially removes any inconsistencies and imperfections on the wheel's surface, which helps maintain the precision of the grinding operation. This is crucial not only for the accuracy of the grind but also for the safety of the operation, as an untrue wheel can lead to vibrations and potential damage to the equipment or the workpiece. Hence, maintaining the correct shape and concentricity directly impacts both performance and safety in grinding applications.
