As a diamond cutting chip manufacturer, you need to know a lot of knowledge. Today, I will share with you the method of dressing diamond cutting blades.
After the diamond cutting piece has been used for a period of time, it needs to be trimmed. Several methods for dressing the diamond cutting piece are described below.
1. Diamond pen dressing wheel Generally speaking, according to the size of the diamond particles and its distribution in the pen, it can be roughly divided into layers, chains, rows and powders. If a strong bonding alloy is used as the bonding agent, the particles of the diamond cutting piece in use are not easily peeled off, so that the particles can be preserved until they are used up, and this process does not need to be trimmed.
2. Rolling method dressing grinding wheel uses the rolling method to trim the diamond cutting piece. Then the grinding wheel will rotate at a speed of 1~2m/s to drive the rolling wheel (made of metal, cemented carbide or abrasive). In addition, since the rolling wheel of the diamond cutting piece is applied to the grinding wheel, there is probably a pressure of 3 to 5 MPa, but the abrasive grains on the surface of the diamond cutting piece are crushed or the abrasive grains can be detached. The rolling method of the grinding wheel is better in cutting performance and lower in cost, but the surface roughness of the workpiece to be ground is very thick, and the rolling wheel is also easy to wear, and the life is relatively short and accurate. Easy to lose. Therefore, when such a dressing method is used, it is usually such a type of grinding that the batch size is small and the precision is not high.
