在普通机床,切割蒸汽机车汽室,风泵胀圈时,当胀圈内、外圆达到规定尺寸后,用硬质合金割刀,切断胀圈。这样,每割一次,须测量一次尺寸。此法,不仅效率低,误差也大。现介绍一种高效切割胀圈法:使用两把硬质合金刀,一把割刀,一把尖头刀。在车床方刀架定位后(两刀保持一定角度),控制两刀尖距离至规定尺寸,即可进行切割。采用此法,可连续切割胀圈,无须重复测量尺寸,大大提高生产效率,很受现场欢迎。
In general machine tools, cutting steam locomotive steam room, wind pump expansion ring, when the expansion ring, the outer circle to the required size, with a carbide cutter, cut off the expansion ring. In this way, cut every time, to be measured once the size. This method, not only inefficient, the error is also large. Now introduce an efficient cutting expansion law: the use of two carbide knife, a knife, a pointed knife. After positioning the lathe square knife holder (two knives to maintain a certain angle), control the distance between the two knives to the required size, you can cut. Using this method, continuous expansion ring can be cut, without having to repeat the measurement of size, greatly improving production efficiency, welcomed by the scene.
