我厂在加工CA-10B型汽车转向壳体内孔时,设计制做了套装式硬质合金单刃铰刀。经生产使用,效果良好。刀具结构及特点(见图): 铰刀有一条切削刃和两个导向条,使刀具本身具有导向作用。切削刃在轴线方向上超前导向条约0.5～1毫米,保证了导向条和孔的已加工面相接触,从面不受铰前预加工孔表面几何形状和光洁度的影响。导向条可承受切削中产生的不平衡力,对接触表面产生挤压,使被加工表面发生微小塑性变
I plant processing CA-10B car steering shell hole, the design made a set of carbide single-edged reamer. After production, the effect is good. Tool structure and features (see photo): The reamer has a cutting edge and two guide bars, so that the tool itself has a guiding role. Cutting edge in the axial direction ahead of the guide strip about 0.5 to 1 mm, to ensure that the guide strip and the hole has been machined surface contact from the surface from the hinge pre-machined hole geometry and surface finish. The guide bar can withstand the unbalanced force generated in the cutting, the extrusion of the contact surface, so that the plastic surface of the plastic deformation occurred
