圆锥配合紧密,装拆方便,虽经多次装拆,仍能保持精确定心作用,在很多机械机构中用作配合表面。它的加工方法很多,有转动小滑板法、靠模法及偏移尾座法等,但转动小滑板法受工件长度的限制,工件锥形长度超过小滑板行程,即不能采用此法,此法还影响工件 Cone with the close, easy assembly and disassembly, despite repeated assembly and disassembly, still able to maintain precise centering effect, used in many mechanical structures with the surface. It has a lot of processing methods, such as rotating a small skateboarding method, a model method and a shift tailstock method, but the method of rotating a small skateboarding method is limited by the length of the workpiece, and the length of the cone of the workpiece exceeds that of a small skateboarding, that is, this method can not be adopted Law also affects the workpiece
