Single Point Diamond Dressers
In the last few decades, single point diamond dressers have, undoubtedly, emerged as the most widely used diamond dressing tools. The prime reason for the popularity of these tools is the versatility offered by them, as they can be used for truing as well as dressing of grinding wheels.
Manufactured using high quality raw diamond that is selected with utmost precaution, Comet single point diamond dresser is formed by either mounting a natural diamond or a bruted diamond at the top of the tool by using a special adhesive. The diamond used in a single point diamond dresser is selected on the basis of the following parameters:
- Dimension of the grinding wheel
- Grit size
- Abrasion type
This tool is available in various sizes with the size and quality of the mounted diamond depending upon its usage. The range of single point diamond dressers offered by us is available in sizes ranging from 0.16 Carat to 5.00 Carat. Depending upon the varying sizes of these single point diamond dressers, they can be used for soft wheels, medium hardness wheels and very hard type of wheels.
Guidelines While Using Comet Single Point Diamond Dresser
To use the tool to its optimum level, it would be wise to keep the following guidelines in mind:
- Comet diamond dresser should be mounted firmly into the holder and, the distance between the diamond and the clamp should be reduced to the least, so as to avoid the diamond from getting ruptured due to vibration.
- Ensure that the diamond tool is never directed at an angle which is opposite to the direction of the rotation of the grinding wheel. To maintain a sharper point, it is essential to check that a drag angle of approximately 10 degrees to the horizontal wheel radius, pointing in the direction of grinding wheel rotation is maintained.
- It is important not to insert comet dressers into the grinding wheel at more than 0.001” (0.025mm) per pass. Cuts deeper than this may cause overheating and, thereby, result in excessive wearing of the diamond.
- A fast traverse dressing rate will produce an open wheel, enabling removal of large stock. On the other hand, a slow traverse dressing rate will impart a finish on wheel which is appropriate for producing a good finish on the work piece.
- In order to maintain a conical point, Comet dresser should be rotated in the holder at an angle varying from 20 to 40 degrees.
- To avoid cracking of the diamond, use ample amount of coolant wherever possible. Always make sure that before beginning with the cutting activity, the coolant is turned on.
- In cases, where dry dressing is performed, do not apply the tool incessantly for longer time, in order to avoid high temperature. Allow the tool to cool naturally instead of doing it with the aid of a coolant. A sudden change in temperature can possibly cause fracture to the diamond, essentially not at the time of shock but in the future use of the tool.
- A diamond dresser should never be worn down to the shank as this might result in dropping out of the diamond. Unusually, a Comet diamond dresser mounted in a dressing tool has more hidden points which, if desired, may be used by resetting.
- A crucial point to be remembered is not to allow a large flat to develop on the cutting point as this may deteriorate the economic life of the diamond.
