摘　　要：针对如何确定单层电镀CBN(立方氮化硼)砂轮磨削区分界线位置,改善窄深槽侧面表明质量这一问题,应用单层电镀CBN砂轮对45#钢工件进行高速深切缓进给磨削实验。在不同砂轮线速度、窄深槽磨削深度和工件进给速度下,对单层电镀CBN砂轮磨削区分界线位置的变化规律进行研究。研究表明:单层电镀CBN砂轮磨削区分界线到砂轮顶部的距离随砂轮线速度的增大而逐渐增大,随窄深槽磨削深度的增加而逐渐减小,随工件进给速度的增大先减小后增大。In order to identify the grinding area boundary of monolayer electroplated CBN pattern grinding wheel and improve grinding surface integrality of profile surface of narrow-deep-groove, the experimental studies on 45 carbon steel workpieces under high-speed deep creep feed conditions were carried out by using monolayer electroplated CBN pattern grinding wheel. In the different value of wheel rotation speed, depth of narrow-deep-groove and feed rate, the law on dividing the edge boundary was studied locating in the grinding position. Experiment results showed that the more the wheel rotation speed increases and the depth of narrow-deep-groove decreases, the more the distance decreases, which is from the grinding area boundary of monolayer electroplated CBN pattern grinding wheel to the top of the grinding. But with the decrease of feed rate, the location of the grinding area boundary will be closer to and then be farther to the top side of the grinding wheel.
