任何工件,只要夹在普通车床主轴三爪卡盘上旋转,车削出的工件形状总圆的。那么,椭圆又是怎样加工呢?现介绍如下: 一、加工原理圆柱形的斜切面是椭圆形。椭圆的长、短轴大小变化,是由斜切角而定的,斜切角越大,长短轴之比越大,反之则越小。二、加工方法过去加工椭圆的方法是旋风头扳角度法(见图 Any workpiece, as long as the ordinary lathe in the three-jaw chuck chuck rotation, turning out of the workpiece shape round. So, how is the oval processing? Now introduced as follows: First, the processing principle Cylindrical bevel is oval. Ellipse length and short axis size changes, is determined by the bevel angle, the larger the bevel angle, the greater the ratio of the length of the axis, the other is the smaller. Second, the processing method The past method of processing oval is the whistling head pull angle method (see Figure
