刚玉涂覆的金刚石树脂砂轮的制造及其应用

本文探讨了采用刚玉涂覆的金刚石制造树脂基砂轮的方法 ,并对比研究了采用不同表面状态的金刚石所制造的树脂砂轮用于磨削金刚石复合片的实验。结果表明 ,采用刚玉涂覆的金刚石制造的树脂砂轮 ,其工作效率比未采用刚玉涂覆处理的金刚石制造的树脂基砂轮提高了 35 % ,使用寿命延长 35 %以上 ;采用涂覆刚玉的金刚石 ,减少金刚石的实际投放量 2 0 % ,其使用性能仍不低于采用原始金刚石制造的树脂基砂轮。

Manufacture and Application of Resin-bonded Corundum -Coated Diamond Wheel

In this paper, diamond coated with corundum was used to fabricate resin matrix abrasive wheel for grinding PCD. The results showed that the efficiency of the wheels made of diamond with corundum coating increased by 35%, its life time also prolonged by 35%. At the same tiem, the consumption of diamonds was reduced by 20%, while the properties of the wheel remains the same
