Where should a diamond dresser be located when dressing a grinding wheel?

When dressing a grinding wheel, the diamond dresser should be located on the outfeed side of the wheel rotation. This positioning is essential because it allows for the effective shaping and truing of the wheel. When the diamond dresser makes contact with the spinning wheel on the outfeed side, it helps to maintain the wheel profile, ensuring that the cutting edge is sharp and free of debris.

Dressing from the outfeed side also allows for the best control of the dressing process, as the wheel tends to push the material away from the dressing tool, preventing any potential gouging of the wheel. This technique leads to a smoother finish on the workpiece because the wheel remains balanced and properly aligned throughout the grinding operation.

By contrast, positioning the dresser on the infeed side could lead to inaccurate shaping of the wheel, as the rotation of the wheel might cause the dressing tool to dig in or disrupt the wheel profile. This could result in excessive wear on the tool or an improperly dressed wheel, which can adversely affect the grinding process and the quality of the finished work.
