陶瓷氧化铝磨料,即所谓的SG磨料,是一种高效磨料。它是用特殊工艺制造的。它的优点是磨粒中不会产生显微裂纹。这种磨料在较大的磨削负荷下使用,耐用度高,有较高的韧性,可进行高速加工。例如用SG磨料对1095高合金钢进行砂带磨削时,磨除率为 Ceramic alumina abrasive, the so-called SG abrasive, is an efficient abrasive. It is made using a special process. Its advantage is that there will be no microcracks in the abrasive grain. This abrasive is used under a large grinding load, high durability, high toughness, high-speed processing. For example, with SG abrasive 1095 high alloy steel belt grinding, the removal rate of
