摘　　要：重点研究了CBN超薄砂轮在快速点磨削过程中的倾斜角和偏转角对砂轮周边接触宽度以及磨削区内任意一点的切削深度的影响情况。建立了砂轮周边接触宽度模型,进而研究磨削转角对砂轮周边接触宽度的影响情况。针对磨削区内距离切削深度最大点任意高度的一点,对该点的切削深度受砂轮倾斜角和偏转角的影响情况进行了研究,建立几何模型,得出该点切削深度的数学公式。为点磨削过程中设置合适的倾斜角和偏转角,以便控制磨削处在理想的状态提供了参考。During the process of quick-point grinding, the tilt angle and deflect angle of super-thin CBN wheel influence the wheel periphery contact width and cutting depth at any point in the grinding zone. To make the research, wheel periphery contact width model is set up, and then the influence of the grinding angle on the wheel periphery contact width is further studied. Aiming at a point at a random height with the maximum cutting depth in the grinding zone, this paper analyses the influence of wheel tilt angle and deflect angle on the cutting depth at this point. Geometric model is set up to obtain the mathematic formula of the cutting depth at the point. Therefore, proper tilt angle and deflect angle are set during the process of point-grinding, for controlling the grinding at the ideal state.
