我们利用C650车床改装成一台旋压机,成功地进行了用钛板旋压锥形管的试验,为发展旋压工艺生产更多品种的异型管,适应飞跃发展的社会主义建设的需要做了一点工作。施压工艺在加工大口径薄壁和某些具有特殊形状要求的管子,以及一些难切削材料具有许多优点:如提高材料的机械性能,节约金属材料等。就以锥形管为例,原来使用 We use the C650 lathe converted into a spinning machine, the success of the test with a titanium plate spinning conical tube, the spinning process for the development of more varieties of special-shaped tube, to adapt to the rapid development of the socialist construction needs to do A little work. Pressuring processes for processing large diameter thin walls and some tubes with special shape requirements, as well as some hard-to-cut materials, have many advantages: increased material mechanical properties and metal-saving. Conical tube, for example, the original use
