Single point "brutted diamond" dressers are made with selected "Congo Rounds" mounted in a matrix. A Single cutting edge is presented to the grinding wheel.
Diamonds for single point dressers are selected in accordance with quality and size. The question of using a superior, average or commercial quality, depends on the grinding finish require, and the machines and working parameters.
We offer three grades namely X, Y & Z for all the diamond size, i.e. from 0.15 to 5.00 carat size.
The dresser must be clamped rigidly in place to avoid vibration once dressing begins.
Considerable care should be taken in mounting the diamond dresser in position. Diamonds are sensitive to shock and impact.
The diamond holder should not be set directly on the centre of the grinding wheel, but at an angle of 5째 -15째 to the direction of rotation of the wheel so that it appears to be "trailling".
At normal wheel peripheral speeds dressing rates of approximately 20-25 m/sec can be achieved.
The maximum depth of cut achieved per dressing pass is 0.03 mm or on fine grit wheels, approximately 0.005-0.01 mm.
The cross feed rate is dependent upon grit size and can have a marked influence on the quality of the finish imparted to the grinding wheel surface. The lower the feed rate, the finer the surface finish. We would recommend the following feed rates per revolution of the grinding wheel.
| Grinding wheel grit size |
Feed rate in mm / rew |
| 180 - 320 |
0.10 - 0.02 |
| 50 - 120 |
0.30 - 0.10 |
| 30 - 46 |
0.60 - 0.30 |
