没有靠模尺装置,要车削锥体,可用图1所示方法,即用饮绳2一端固定于床身挡块1,一端绕在特制的盘5上。当刀架4向右走刀时,盘5转动,通过横向丝杠使横拖板7移动,刀具6即可加工出锥体工件3。因此,只要作一个绳盘,就可加工锥体。盘的直径D可用下式求得:tgα=h/πD式中h为横向丝杠螺距,α为锥顶半角。例如,α=2°, Without the ruler device, turning the cone, the method shown in Figure 1 can be used, that is, one end of the drink line 2 is fixed to the bed block 1, and one end is wound on a specially-made dish 5. When the tool holder 4 is going to the right, the disc 5 is rotated, the horizontal carriage 7 is moved by the horizontal screw, and the tool 6 can process the cone-shaped workpiece 3. Therefore, as long as a rope reel, you can process the cone. The disc diameter D can be obtained by the following formula: tgα = h / πD where h is the horizontal lead screw pitch, α is the cone top half angle. For example, α = 2 °,
