对于内表面是由圆弧线和直线相连接所组成的连线,相对于某轴心线作旋转,所形成的回转曲面的零件,目前大多采用杠杆式靠模车削加工。如图1所示,加工过程是由主导的纵向进给和随动、并可以绕刀架中心旋转的杠杆摆动来完成。刀具安装在杠杆的方孔中,滚轮紧贴靠模板型面,并沿靠模板型面作相对运动。 For the inner surface is formed by the connection of circular arcs and straight lines, relative to the axis of rotation, the formation of the rotary surface of the parts, most of the current use of leverage by the mold turning. As shown in Figure 1, the machining process is dominated by longitudinal feed and follow-up and can be done by pivoting the lever about the center of the carriage. Tool installed in the square hole in the lever, roller close to the template surface, and along the template for relative movement.
