Xiangyang America were detected Ltd. development and operation of polishing abrasive materials are preferred, advanced preparation process to ensure the quality of the grain into the shape of equal area; strict grading process to ensure that the actual size and nominal size consistent with a high proportion of particles, the size composition are higher than the national standard size range requirements. These materials are suitable for metallurgical metallurgical and petrographic grinding, polishing, but also for a variety of ferrous and nonferrous metals, ceramics, composite materials, and precious stones, instrumentation, optical glass products such as high-quality finish grinding and polishing. Fine abrasives needed to get to get ultra-precision polishing plane. Abrasive Type alumina (corundum), diamond, silicon carbide, silicon carbide, chromium oxide, cerium oxide, silica (colloidal silica) abrasive particle size: (microns) w0.03 w0.05 w0.5 w1 w1.5 w2.5 w3.5 w5 w7 w10 w14 w20 w28 w40 w50 w63 support suspension of abrasive, abrasive paste, powder wherein the particle size of 0.05 micron alumina suspension, a particle size of 0.04 microns silica suspension. For a variety of materials, ultra-fine polishing
