为了提高车床加工回转体零件的生产率和精度,可围绕着零件,在—个平面内,按均匀的角距安装几把同时工作的车刀。这样,切削力相互平衡,能补偿在切削力作用下产生的弹性形变。为把这种方法付诸实施,研究出一种多刀自定心刀架(图1),它可用于万能车床,也可用于数控车床。 In order to improve the productivity and accuracy of turning parts for lathe machining, a number of simultaneous turning lathes can be mounted on a flat surface at even angular intervals around the part. In this way, the cutting forces are balanced with each other to compensate for the elastic deformation caused by the cutting forces. In order to put this method into practice, a multi-knife self-centering tool holder (Fig. 1) was developed which can be used on a universal lathe or a CNC lathe.
