NBN 800 abrasive grains are all microcrystalline, with high compressive strength and thermal stability. Due to its unique crystal characteristics, the abrasive has sharp corners regardless of size when it is broken by force, so that it can always maintain sharp grinding performance during use, so the grinding force generated during grinding is small, the power consumption is low, the processing quality is good, and the service life is long. It is widely used in diamond tools for automobile and aerospace industries.
