Quality assurance and processing capacity are essential performance parameters of abrasive tools. It is of prime importance for grinding wheels operating at a speed of 35–60 m/s. In this case, opportunities to increase grinding efficiency without burns are associated with using high-porosity and low-hardness wheels. Artificial pore-forming agents are used to manufacture tools. The introduction of pore-forming agents decreases grinding forces and increases the maximum grinding depth without burns. The grinding ratio decreases as the content and grit size of pore-forming agents increase. Since the introduction of pore- forming agents with the grit size exceeding that of the abrasive material increases the distance between the abrasive material’s grains, the surface roughness of grinding with high-porosity wheels is slightly higher, which requires using wheels with a lower grit size of the abrasive material. In general, a possibility to apply deeper grinding without burns emerges, which increases capacity, ensuring the required metal-surface quality.
