车削端面时,常出现光洁度低,而且越靠近中心光洁度越低,大型车削端面更突出。端面与轴心线垂直度低,并常呈内凹状,车削刚性较差的盘类零件端面尤其明显。造成光洁度低的主要原因是:(1)车削端面时,由于工件旋转的主运动与刀具的走刀运动合成的结果,使刀尖的运动轨迹为一平面阿基米德螺旋线(图1),刀刃实际切削的表面并非一正圆柱面,而为一阿基米德螺旋面。刀刃
Turning end face, often appear low finish, and closer to the center of the lower finish, large turning face more prominent. End face and the axis of the low verticality, and often concave shape, turning the poor rigidity of the disc-like parts of the end surface is particularly evident. The main reasons for the low finish are: (1) turning face, due to the workpiece rotation of the main movement combined with the tool cutting tool movement, the tip of the trajectory of a plane Archimedes spiral (Figure 1) The actual cutting surface of the blade is not a true cylindrical surface, but an Archimedes screw surface.
