目前在国家的許多机器製造廠中,其中包括克拉馬托尔斯克斯大林机器製造廠,成功地採用旋風法來車削直徑至150公厘的螺紋。旋風头通常按刀具的內接觸方式工作。这个方法的优越性在於:(a)刀具的设备簡單(它們按第一把車刀所切出的痕跡來安裝);(6)剖面的限制小;(B)螺纹的表面光潔度高(7～8级光潔度)。但是这个方法也存在着很大的缺點,就是不可能車削直径大於150公厘的螺紋,因为这時旋風头的结构就会变得很笨重,故僅对於車削直径在一定範圍內的螺纹才有用。因此,克拉馬托尔斯克斯大
At present many machine builders in the country, including the Stalin manufacturing plant in Kramatorsk, have succeeded in using the whirlwind method to turn threads up to 150 mm in diameter. Cyclones usually work in contact with the tool. The advantage of this method is that: (a) the tools of the tool are simple (they are installed according to the marks cut by the first turning tool); (6) the restriction of the profile is small; (B) the surface finish of the thread is high 8-level finish). However, this method suffers from the great disadvantage that it is impossible to turn a thread having a diameter of more than 150 mm because the structure of the cyclone head becomes bulky. Therefore, it is only possible for a thread of a certain diameter within a turning diameter it works. Therefore, Kramatorskos
