目前常用的浮动镗刀刀体多为可调整的长方形结构,也有整体圆形结构。但两者都有一定的局限性,前者刃磨时难以保证两刃对称性,刀杆方孔较难制造;后者因结构不可调影响了刀具寿命。为克服这些缺陷,我厂在综合分析的基础上,设计了可调圆片浮动镗刀。 1.结构与调整 At present, the floating boring cutter body commonly used for the adjustment of the rectangular structure, but also the overall circular structure. However, both have some limitations. When the former sharpening is difficult to guarantee the symmetry of the two blades, the square hole of the arbor is more difficult to manufacture; the latter is not adjustable because of the structure, which affects the tool life. In order to overcome these defects, based on the comprehensive analysis, our factory designs the adjustable wafer floating boring tool. 1. Structure and adjustment
