Faced with various diamond tools in the market, how can we successfully avoid entering the pit? Diamond is one of the known mineral materials with high hardness and good thermal conductivity. It is an ideal material for making cutting tools.
Diamond tools (also known as diamond tools) are characterized by high hardness and wear resistance, low friction coefficient, sharp cutting, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals.
When selecting tools, please pay attention to the following points
1. Selection of granularity
When the particles of the diamond tool are very thick and there is only a single particle, the blade head is very sharp and the cutting efficiency is very high. However, the bending strength of the diamond tool agglomerates will be reduced; When the diamond cutter particles are fine or coarse and fine, the saw blade can be used for a long time, but the relative efficiency is low. The number of particles of the diamond cutter is between 50 and 60.
2. Selection of distribution density
If the distribution density of diamond tools 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.
3. Selection of strength
The diamond tool with too high strength will make the crystal difficult to be cut, and the abrasive particles will be polished when used, and the sharpness will be reduced, resulting in poor performance of the tool; When the strength of diamond tool is low, it is easy to break after the crystal is impacted, and it is difficult to shoulder the responsibility of cutting amount. Therefore, it is good to choose a diamond tool with strength between 13 and 140n.
When selecting 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.
