What does a wheel dresser do to a grinding wheel?

A wheel dresser is a tool used to maintain and optimize the performance of a grinding wheel. Its primary function is to recondition and shape the wheel, which is essential for ensuring that the wheel can efficiently grind materials while maintaining the desired surface finish and precision.

Over time, grinding wheels can become blunt, loaded with abrasive particles, or take on an undesirable shape due to wear and tear during the grinding process. By using a wheel dresser, the operator can restore the grinding wheel to its original condition, ensuring that it wears evenly and operates effectively. This reconditioning process involves removing worn or damaged material from the wheel surface, which not only allows for improved cutting action but also enhances the wheel’s ability to remove material from the workpiece during grinding.

Understanding this function highlights the importance of keeping grinding wheels properly shaped and dressed for optimal performance in machining tasks.
