过去,我厂小型水轮发电机上的定子扇形片冲模的内外圆弧面,都是在C512A立车或C630车床上附加一磨头进行加工。调整和加工都费工时,且质量不稳定。后来生产中型水电设备,扇形片冲模直径为3250毫米。这就更不能采用原来的方法加工了。面对这种情况,我们自制了一台圆弧磨床(见图1),不仅解决了一般中型发电机定子扇形片冲模刃口的磨削加工,还
In the past, the inner and outer arc surfaces of the stator segment die on the small turbine generator of our factory were processed by adding a grinding head to the C512A vertical lathe or the C630 lathe. Adjustment and processing are man-hours, and the quality is not stable. Later, the production of medium-sized hydropower equipment, fan-shaped die diameter 3250 mm. This can not even use the original method of processing. Faced with this situation, we made a circular arc grinding machine (see Figure 1), not only solved the general medium-sized generator stator fan blade die grinding process, but also
