用旋转滚压加工内孔是表面塑性变形加工的一种。研究表明,这种加工方法产生的轴向力不大,所以在车床、床车、铣床和组合机床上都可以应用。滚压头固定在刀杆上,滚压头与刀杆保持同轴。加工内孔时(图1),其轴线相对于工件的旋转轴线倾斜一个角度δ,使球状滚压头的几何中心位于工件的旋转轴线上。当工件旋转速度为n时,纵向进给为s。滚压头与工件接触时,被工件带动,以速度n_1旋转。而且,当工
Rotating the inner hole with a rolling process is a form of plastic deformation. Research shows that this method of processing produces little axial force, so it can be used on turning machines, bed lathes, milling machines and combined machine tools. Rolling head is fixed on the arbor, roller head and arbor remain coaxial. When machining the inner hole (Figure 1), its axis is inclined at an angle δ with respect to the axis of rotation of the workpiece so that the geometric center of the spherical roller head lies on the axis of rotation of the workpiece. When the workpiece rotation speed is n, the longitudinal feed is s. Rolling head contact with the workpiece, the workpiece driven, with speed n_1 rotation. And, as a worker
