以往,在斜面上钻孔时,我们常采用鍯平再钻孔或加钻套钻孔等。在实践中我们采用旋转工件(中小型)法钻斜孔,这样既不须鍯也不须加钻套,而且钻孔效果较好,对单件生产尤其经济实用。其原理:工件旋转使斜面形成圆锥形,故钻孔时的径向分力F_1(如图)是随工件旋转而不断变换方向的,从而成为一个向心力,使得钻头不偏离轴线,故加工出来的孔偏差较 In the past, when drilling on the bevel, we often use 鍯 then drill or drill holes and other drilling. In practice, we use the rotating workpiece (small and medium-sized) method oblique hole, so that neither need nor add drilling sets, and drilling better, on a single production is particularly economical and practical. Its principle: the workpiece is rotated so that the bevel cone shape, so the radial component of the hole when drilling F_1 (Figure) is with the rotation of the workpiece constantly changing direction, so as to become a centripetal force, so that the drill does not deviate from the axis, so the processed Hole deviation than
