过去我厂加工图1的零件时,先用圆弧车刀粗车成形(留研量0.05～0.1毫米),淬火后再进行研磨,才能达到图纸要求。这种方法有以下缺点: 1.车削时需调头,增加了辅助时间。2.用研磨方法工效低,并且不易保证质量。为了克服以上缺点,我们改用磨床加工,加工方式如(图2)所示:将工件装在用顶尖顶住的心轴上,并用顶絲固定住。加工时,工件沿R=d/ 2旋转,而砂轮绕本身主轴旋转,两个运动合成轨迹就
In the past I plant processing parts of Figure 1, the first car with a rough turning car shape (studying the amount of 0.05 to 0.1 mm), after quenching and then grinding in order to meet the requirements of the drawings. This method has the following disadvantages: 1. Turning to turn the head, an increase of auxiliary time. 2. With the grinding method is inefficient, and not easy to ensure quality. In order to overcome the above shortcomings, we use the grinder machining, as shown in Figure 2: The workpiece is mounted on the spindle to withstand the top and fixed with top wire. Processing, the workpiece along the R = d / 2 rotation, while the wheel rotates around its own spindle, the two synthetic trajectory
