我厂生产的铜铝合金轴瓦是用无缝钢管作瓦背。由于没有切割管子的设备。过去是先把整根的管子用氧气切割成几段,再拿到车床上切割到所需要的尺寸。这样做,既要消耗大量氧气,又费材料,很不经济。经过改革,现在我们是在C630车床大拖板上安装了浮动卡头中心架(见附图)、操作时,将整根的钢管一端卡在三爪卡盘上,另一端卡在浮动卡头中心架上,留出切割长度。当主轴转动后,工件(钢管)就带动浮动卡头同时转动而进行切割。
The copper aluminum alloy bearing produced by our factory is made of seamless steel pipe. Because there is no pipe cutting equipment. In the past, the whole pipe was cut into several sections with oxygen and then cut to the required size on a lathe. In doing so, it is not economical to consume large amounts of oxygen and materials. After the reform, now we are in the C630 lathe mounted on a large floating card holder center frame (see photo), the operation, the entire root of one end of the pipe stuck in the three-jaw chuck, the other end stuck in the floating chuck Center rack, leaving the cutting length. When the spindle rotates, the workpiece (steel pipe) will drive the floating chuck to rotate at the same time to cut.
