Advantages

  • Through the airflow mill and five layer classification, the grain size distribution is narrow, the grinding efficiency is high, the polishing effect is good, the grinding efficiency is much higher than the soft abrasives such as silica.
  • Good particle appearance, the surface of the object to be polished has a high degree of smoothness, in the last fine polishing procedure, the effect of the grinding and polishing is better than white corundum powder.

Application

  • 01

    Widely used in the grinding and polishing of semiconductors, crystals, aluminum, steel, stainless steel, stone, glass, etc.

  • 02

    Especially suitable for the mirror effect grinding and polishing of stainless steel, copper, other metal materials, and the glass industry.
