为了在难加工材料制零件内通过连续补偿刀具磨损的方法提高深孔精镗的精度和生产率,本文提出了一种单刃镗刀新结构(见苏联发明证书1093410)。在刀体1的槽2内配置扇形浮动刀片3。其中安装切削元件6和支承元件4和5。支承元件对切削元件错开的角度小于180°。导向元件7和8在加工过程中分别承受切向和径向分力。为了连续补偿磨损,切削元件的刃边配置在导向元件和支承元件接触加工孔
In order to improve the precision and productivity of deep-hole precision boring by continuously compensating tool wear in the parts made of difficult-to-process materials, a new structure of single-boring boring tool is proposed in this paper (see Soviet Union invention certificate 1093410). A sector-shaped floating blade 3 is arranged in the groove 2 of the cutter body 1. In which the cutting element 6 and the support elements 4 and 5 are mounted. The angle at which the support element is offset from the cutting element is less than 180 °. The guide elements 7 and 8 respectively bear tangential and radial component forces during machining. For continuous wear compensation, the cutting edge of the cutting element is arranged between the guide element and the support element in contact with the machining hole
