[Alcoa.com] The dew or protruding height of the diamond on the cutting surface of the sawing tool will affect the depth of cut of each particle, that is, the material removal rate of the cutting tool. The use of coarser diamond dew exposure will have a faster material cut rate. Generally coarse particles are used to cut soft materials, while smaller particles are used as hard material for cutting.
The particle size of the diamond determines the number of particles per carat. As the particle size increases, the number of particles per carat increases. Because the number of diamonds on the cutting area of ​​the tool has an impact on tool life and power consumption, choosing the right mesh is the key to ensuring tool performance. In general, the use of fine-grained diamond for low-density diamond tools can increase the amount of diamond particles on the surface of the cutting tool, which in turn helps increase the lifespan and also increases power consumption.
In addition to the diamond grain size, the diamond concentration also determines the number of grains on the surface of the cutting tool. The higher the diamond concentration, the greater the number of grains on the surface of the cutting tool, which contributes to an increase in life.
