钩舌 S面磨耗过限以后 ,需进行堆焊 ,然后加工恢复原型。然而 ,制造一种能进行 S面仿形加工的设备 ,一直是全路各车辆段研究的课题 ,现在 ,有的单位采用专用铣床进行加工 ,但价格较贵 ,怀化车辆段采用对现有的 B665型牛头刨床进行数控改造的方法 ,达到了理想的效果 ,下面作一简 Knuckle S surface wear over the limit, the need for welding, and then restore the prototype processing. However, to create a device that can perform S-plane profiling has always been the subject of research on all the depots across the road. Now some units use special milling machines for machining but the prices are expensive. B665-type shaper CNC transformation method, to achieve the desired effect, the following for a simple
