对箱体加工,其孔的端面与孔的中心线有严格的垂直度要求。过去加工孔的端面,常采用单刀刮削,这样,很容易产生“凹心”与“凸肚”,特别是孔径较小、端面较大、孔的端面与平旋盘的距离较远时,由于镗杆的刚性较差,所刮削的端面与孔中心线的垂直度、光洁度很难达到要求。采用端面镗杆,可解决上述问题。 On the box processing, the hole’s end face and hole centerline has a strict verticality requirements. In the past, the end face of the machined hole was often shaved by a single knife. In this case, “concave heart” and “convex belly” were easily generated. Especially when the aperture was small and the end face was large, the distance between the end face of the hole and the flat turret was far. Boring bar less rigid, scraped end face and hole centerline of the verticality, finish is difficult to meet the requirements. Using face boring bar, can solve the above problems.
