在精加工孔时，尤其是当孔的形位公差要求严格时，经常采用镗削加工的形式。为了保证加工精度，需用带微调机构的镗刀头尾部的螺钉来保证，这种镗刀只能加工直径较大的内孔。本文以汽车倒挡惰轮镗孔用刀为例，介绍一种加工较小直径内孔的楔块微调式可转位镗刀。１镗刀使用条件

When finishing the hole, especially when the hole shape tolerance requirements are strict, often used in the form of boring. In order to ensure machining accuracy, the need to use fine-tuning mechanism boring head tail of the screw to ensure that such boring tool can only be processed diameter larger bore. In this paper, an example is taken of the cutter for the idler wheel of a reverse car, and a description is given of a finely adjustable wedge adjustment boring cutter capable of machining a bore with a smaller diameter. 1 boring tool conditions
