The most important part of diamond tool is diamond, because when the tool works, the diamond is mainly used for cutting or polishing with objects.
Therefore, for the selection of diamond tools, namely the selection of diamond, the following is to introduce the selection of reference points:
1. Selection of granularity
When the diamond particles are very thick and there is only a single particle, the blade tip is very sharp and the cutting efficiency is very high. However, the bending strength of diamond agglomerates will be reduced.
When the diamond particles are fine or coarse and fine mixed, the blade tip can be used for a long time, but the efficiency is relatively low.
The number of diamond particles is suitable between 50 and 60.
2. Selection of distribution density
If the distribution density of diamond changes from small to large, the sharpness and efficiency of the saw blade will gradually decrease, leading to a longer service life.
But too much density can make the blade less sharp.
If the distribution density that USES is lower, granularity is coarser, efficiency can be promoted.
The efficacy of each part of the blade is different when the blade is cut. When the blade is cut with different concentration, the middle depression appears in the operation of the blade in the process of saw cutting, which is very beneficial to avoid the swing of the blade.
3. Selection of intensity
The diamond with too high strength will make the crystal not easy to be cut, and the abrasive particles will be polished when being used. As a result, the sharpness will decrease and the performance of the tool will deteriorate.
When the strength of diamond is low, the crystal is easy to be broken after being impacted, so it is difficult to shoulder the responsibility of cutting forehead.
Therefore, it is better to choose a diamond strength between 13 and 140N.
When selecting diamond tools, it is also necessary to pay attention to the selection of bonding phase and diamond sintering process. Each aspect requires attention, and the selection must be paid attention to.
