刀具调整装置的径向跳动。正如已经指出的那样,由于刀具调整装置各环节的制造误差,使紧固在主轴上的刀具悬臂轴线对主轴轴线有偏差。其结果是,刀具自由端在主轴回转时产生径向跳动2γ(图57)。刀具轴线相对主轴回转轴线的偏移量γ等于刀具端部径向跳动的一半: γ=f(e-1,e_2,e_3,e_4,e_s,ε) (65)式中e_l——主轴轴线相对于回转轴线的偏移量(为其跳动量的一半);e_2——由于接杆用紧固螺钉固定在主轴上产生了间隙,造成接杆配合直径轴线相对于主轴轴线的偏移;
Tool adjustment device radial runout. As already pointed out, due to the manufacturing error of the various parts of the tool adjusting device, the tool cantilever axis fastened to the spindle deviates from the spindle axis. As a result, the free end of the tool generates a radial runout 2γ when the spindle is rotating (Figure 57). The offset γ of the tool axis with respect to the axis of rotation of the spindle is equal to half of the radial runout at the tool end: γ = f (e -1, e_2, e_3, e_4, e_s, ε) (65) where e_l - The amount of deviation from the axis of rotation (half of the amount of runout); e_2 - due to the connecting rod is fixed on the spindle with a fastening screw there is a gap, resulting in the axis of the rod with the axis offset relative to the spindle;
