Single Point Diamond Dressers

Single point brutted diamond dressers are made with selected congo rounds mounted in a matrix.
Diamonds for single point dressers are selected in accordance with quality and size. It is normally based on the required grinding finish, machine, working parameters, size and type of wheels.
Guidelines:
- Considerable care should be taken in mounting the diamond dresser in position. Diamonds are sensitive to shock and heat.
- The dresser must be clamped rigidly in place to avoid vibration once dressing begins.
* Ample supply of coolant should be directed at the point of contact of the diamond point before dressing begins. Sudden application of coolant to the diamond dresser once the diamond gets heated up could cause it to shatter .
* The diamond holder must not be set directly on the center of the grinding wheel but an angle to the direction of rotation of the wheel so that it appears to be trailing.
* 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 speed, the finer the surface finish.
Applications:
* Single point dressers are used for OD and/or side dressing of conventional wheels. They can be used on cylindrical grinders, surface grinders, tool and cutters. Also for larger profiles, male or female generations on wheels, or to remove the existing profiles (random dressing). They can also prepare the wheel for a fresh form.
