Selection principle of SPC high speed line processing solution operation
Selection of granularity
When the diamond particles are very coarse and there is only a single particle, the cutting head of the saw blade is very sharp, and the cutting efficiency is very high. However, the bending strength of the diamond agglomerates will be reduced; When the diamond particles are fine or coarse and fine, the saw blade can be used for a long time, but the relative efficiency is low. It is appropriate to select the number of diamond particles between 50 and 60.
Selection of distribution density
If the distribution density of diamond changes from small to large, the sharpness and sawing efficiency of the saw blade will gradually decrease, and the service life will gradually become longer; However, if the density is too high, the saw blade will become less sharp. If the distribution density is low and the particle size is coarse, the efficiency will be improved. The effect of each part of the cutting head is different when sawing and cutting. When the concentration is different, the middle depression occurs during the operation of the cutting head in the sawing process, which is good for avoiding the deviation of the saw blade.
Selection of strength
The diamond with too high strength will make the crystal difficult to be cut, and the abrasive grains will be polished when used, and the sharpness will be reduced, resulting in poor performance of the tool; When the strength of diamond is low, it is easy to break after the crystal is impacted, and it is difficult to shoulder the responsibility of cutting amount. Therefore, the diamond strength should be between 13 and 140n.
When purchasing diamond tools, we should also pay attention to the selection of the bonding phase and the selection of the diamond sintering process. Every aspect needs attention, and we must pay attention to it when selecting.
