摩擦式微调镗刀是一种既可实现轴向镗削,又可实现横向自动进刀的孔加工两用工具,可装在立铣主轴或车床尾座中使用。现结合在立式铣床上的应用,介绍如下: 一、刀具结构如图所示,刀具由刀套1、刹紧环7、刻度环10和刀杆12等基本件组成。在刀杆12下方开一长方孔,孔内装有刀套1。刀套如同一把浮动镗刀,可在刀杆内滑动,其配合精度同浮动镗刀与刀杆的配合要 Friction trimming boring tool is a kind of dual-purpose tool which can realize both axial boring and horizontal infeed. It can be used in the milling spindle or lathe tailstock. Now combined with the application of vertical milling machine, described as follows: First, the tool structure shown in the figure, the tool set by the knife 1, 7, 7, ring 10 and the basic elements such as the arbor 12. In the cutter bar 12 to open a rectangular hole below the hole with a knife holder 1. Knife sleeve as a floating boring knife, can slide in the cutter bar, with its precision with the floating boring knife and arbor with the need to
