目前有些工厂利用如图1所示的工具在车床上车削六方形截面的柱体,甚至还用类似的工具车削三方、四方、八方或多边形截面的柱体。其实更重要的是利用类似的工具也可车削椭圆形截面的柱体。本文仅就该工具的工作原理以及用它车削多边形时所车削的直线边的不直度作一简单 At present, some factories use the tools shown in Figure 1 to turn hexagons with hexagonal cross-section on lathes and even use similar tools to turn columns with three, four, eight or polygon cross sections. In fact, more important is the use of similar tools can be carved oval cross-section of the cylinder. This article only on the working principle of the tool and use it when turning the polygon straightness of the straightness of the straightforward to make a simple
