在镗床上镗孔,当遇到距离较长或孔径大于80毫米,超过一般偏心刀杆加工范围时,通常用一般刀杆或长杆敲刀镗削。但是,在单件生产或机修中,如遇到孔不在明显的位置,譬如,缩在里面,不但测量尺寸很困难,而且用敲刀镗削孔径精度也难保证。针对以上情况,我们采用以下两种镗杆,取得了较好的效果。

Boring boring machine, in the face of a longer distance or larger than 80 mm aperture, more than the general machining range of eccentric arbor, usually with a general arbor or long rod tapping boring. However, in a single piece of production or machine repair, if the hole is not in a prominent position, for example, shrink inside, not only the measurement of the size is very difficult, but also with a knocking boring aperture accuracy is difficult to guarantee. In view of the above situation, we use the following two kinds of boring bar, and achieved good results.
