在单件和成批生产中,铰孔是精加工孔的一种方法。实际生产中,有许多复杂的工艺因素综合地影响着铰孔质最。往往出现孔表面不光,孔径扩大或呈喇叭孔,成为铰孔时的主要质量问题。现将我们多年来制造和使用铰刀的经验,简述如下: 一、铰孔表面不光及改善方法 1.铰削速度太大铰孔时切削用量各要素对孔的光洁度都有影响,其中以铰削速度影响最大。用高速钢铰刀加工钢件,要得到7以上的光洁度,铰削速度不应超过5
Reaming is a method of finishing holes in single-piece and batch production. In actual production, there are many complex process factors that affect reaming the most comprehensive. Often appear not only the surface of the hole, the aperture is enlarged or was horn hole, a reaming hole when the main quality problems. Now we have many years of experience in manufacturing and using reamers, summarized as follows: First, not only the reaming surface and improve the method 1. Reaming speed is too large Reaming amount of cutting elements on the hole finish have an impact, of which Reaming speed has the greatest impact. High-speed steel reamer steel processing, to get more than 7 finish, reaming speed should not exceed 5
