Single Point Diamond Dresser
The Single Point Diamond Dresser is more versatile and it is used for truing and dressing purpose of grinding wheel. The diamond for the single point dressing tools are chosen on the basis of their structural strength, degree of sharpness, & lack of detrimental flaws. The proper selection of single point diamond dresser depends on the dimension of grind hardness, grit size and abrasive type.

RECOMMENDATIONS FOR CORRECT DIAMOND USAGE
Dressing should start at the Center Of Wheel :- Dressing should always start at the largest diameter, generally that would be the center. If dressing is started at the side of the wheel, it is very easy to and destroy even the finest of diamonds.
Angle of tool should be at a 10 - 15 degree drag in the direction of wheel rotation. Both should be held rigid and free from vibration. This prevents chatter marks that could easily ruin the wheel for use and might crack the diamond.
Use coolant generously.
Turn diamond dresser frequently to insure sharp points.
DRESSING :
Bring diamond to high point of grinding wheel. Turn on coolant. See that a copious amount is flowing on both diamond and wheel. Start traverse feed 18" to 30" per minute. Take two or more passes across face of wheel. (Stop here if rough dressing is desired). To obtain finish dressing, continue from above. Change traverse fee to 6" to 15" per minute. Proceed with at least 2 passes at .001" penetration followed by one or two passes at.0005" penetration. (Stop here for good commercial finish). Remove loose particles from face of wheel by using a small piece of hard wood or fiber.
Diamond dresser should be on the center line of grinding wheel or 1/32" below, never above.
To avoid wheel taper, position diamond dresser as near as possible to the area where the grinding is being performed. When completing last pass of dressing operation allow same to finish in the same direction each time
