在立式钻床上加工一组孔,一般方法都是采用划线方法,划出加工孔的中心线,然后进行钻孔,扩孔,铰孔,孔的尺寸精度很容易达到要求,但是,由于划线的精度比较低,加工时,找正孔的中心线也有很大的误差,很难保证孔距的精度要求,所以,借助一些辅助工具和高精度测量工具,就可以达到加工精度的要求。

In a vertical drilling machine to process a group of holes, the general method is to use the scribing method, draw the centerline of the processing hole, and then drilling, reaming, reaming hole size accuracy is easy to meet the requirements, but due to Scribing accuracy is relatively low, processing, find the centerline of the hole is also a big error, it is difficult to ensure the accuracy of pitch requirements, so, with some auxiliary tools and high-precision measurement tools, you can meet the requirements of processing accuracy .
