苏联东捏兹克市工艺设计研究院设计了一种可调节加工尺寸、或在刀具磨损后可调整补偿的孔加工刀具(见图)。作者发明证书编号:(苏联)1069963。在壳体7的长方孔11内心轴5上偏心布置圆盘形切削刃具6,切削圆盘可在下调节件3和上调节件9相互配合作用下在心轴5上旋转,而上下调节件的轴向移动是通过调整调节螺钉1和8获得的。因为调节件3和9在其凹槽4和10中装有切削圆盘,所以不能转动。调节件与切削圆盘的接触点偏
The Tunut Institute of Process Design of the Soviet Union designed a hole-machining tool (see photo) that can adjust the machining size or compensate for tool wear. Author Certificate Number: 1069963. A disc-shaped cutting tool 6 is arranged eccentrically on the mandrel 5 of the oblong hole 11 of the housing 7. The cutting disc can be rotated on the mandrel 5 under the cooperation of the lower adjusting part 3 and the upper adjusting part 9, The axial movement is obtained by adjusting the adjusting screws 1 and 8. Because the adjusting members 3 and 9 are equipped with cutting discs in their recesses 4 and 10, they can not rotate. Adjuster and cutting disc contact point deviation
