本文是一篇关于能在半径方向调整切刃的镗孔工具的专利。在本体的前端部设有滑动导向用的细齿,刀块1、2可沿半径方向导向调节。刀块通过孔并借助紧固螺钉固定在本体上。紧固螺钉可在相对于回转轴倾斜的长槽内导向移动。长槽与垂直于回转轴的横孔相 This is a patented boring tool that adjusts the cutting edge in the radial direction. At the front end portion of the main body, a fine guide tooth is provided for guiding the sliding movement. The knife blocks 1, 2 are guided and adjusted in the radial direction. The knife block passes through the hole and is fastened to the body by means of fastening screws. The tightening screw can be guided for movement in a long slot that is inclined with respect to the axis of rotation. Long slot and perpendicular to the axis of rotation of the horizontal hole phase
