The exposure or protruding height of the diamond on the cutting surface of the sawing tool will affect the cutting depth of each particle, that is, it will affect the material removal rate of the cutting tool.
The use of larger diamond grit exposed degree will have a faster material removal rate. Generally coarse particles are used to cut soft materials, while smaller particles are used to cut hard materials. The grit of diamond determines the number of particles per carat. The number of particles without carat increases with the increase of the grit. Because the number of diamonds in the cutting area of a tool has an impact on the tool's lifespan and power consumption, thus selecting the right mesh number is the key to ensure the performance of the tool. Generally speaking, the use of fine-grained diamond for low-concentration diamond tools can increase the diamond particles on the surface of cutting tools, this not only helps to improve the lifespan, but also increases the power consumption. In addition to the diamond grit, the diamond concentration also determines the number of grain on the surface of the cutting tool. The higher the diamond concentration is, the more the number of crystal on the surface of the cutting tool.
