Single Point Dresser - Diamond Tip With Concentric Shank, Ideal For Fine-grain And Small Diameter Grinding Wheels

The original and most basic dressing is the single point process, performed by a single diamond tip. It can provide a very accurate profiling of the wheel, and is the simplest system, not requiring any special device. In this type, dressers with a selected diamond crystal mounted on a shank. The point of the set diamond is concentric with the shank.

In wheel dressing by means of single point dresser, normally a depth of cut of about 0.02-0.05 mm and a rapid traverse is applied till the wheel becomes true. For finishing, the depth of cut is reduced to 0.01-0.02 mm and the traverse is reduced to about 0.1 m/min. For dressing diamonds, normal working speed of grinding wheel is applied. The diamond dresser should be attached at an angle of 10~15 degrees from the horizontal axis of the grinding wheel.

On the negative side the dresser has short life due to the small size of the tip. A single point diamond should not be allowed to become dull, as it will produce a closed surface on the grinding wheel, which affects the grinding wheel performance.

These dressers are highly suitable to fine-grain grinding wheels and small diameter grinding wheels, also suitable for larger diameter grind wheels with small widths. Single point dressers are nowadays used mostly in very cheap, simple, general purpose machines or to obtain complex profiles in low to medium production applications.
