Truing is the process of making the outside of a grinding wheel concentric to the axis. Truing can also include putting a special form or contour into the wheel. Dressing is the process of sharpening the abrasive that comes in contact with the component being ground.
The recently updated Wheel Dressing Manual includes step-by-step procedures for proper wheel dressing including how to position the tool, the effects of slow and fast traverse rates, tool handling and maintenance tips, use of coolant and when to dress. The manual also provides do's and don'ts for single and multi-point dressing tools, how to avoid vibration and the amount of wheel removal per pass.
