在机械制造业中,广泛采用双刃刀片的浮动镗刀,安装在刀杆的长方孔内进行镗孔。这种刀具称为自调式镗刀。实际使用表明,这种镗刀不能消除刀具和毛坯轴线的不同轴度。在尺寸稳定和刀具使用可靠的条件下,不能满足高生产率加工的要求。本文介绍一种新型自调式三刃镗刀,可用以精镗长为4000～5000mm 的管子,且生产率较高。这种镗刀,当切削部分切入毛坯端面时,在刀体上调整较简单,并且,以调
In the machinery manufacturing industry, widely used double-edged blade floating boring knife, installed in the cutter bar rectangular hole for boring. This tool is called a self-aligning boring tool. Practical use shows that this kind of boring tool can not eliminate the different axes of tool and blank axis. Under the conditions of stable size and reliable use of tools, the requirements of high-productivity machining can not be met. This article describes a new self-adjusting three-blade boring tool, can be used to fine boring 4000 ~ 5000mm length of the tube, and high productivity. This boring tool, when the cutting part into the blank end face, adjust the knife body is relatively simple, and to adjust
