在车床上镗大孔径深孔时,一般采用浮动刀排,以减小刀杆振动及克服切削过程中的让刀现象,但横向进给很难控制。因此,我们经试用可微调浮动刀排,效果很好,能保证零件的精度,且能扩大加工范围,安装方便,调节简单。其使用方法是:先根据零件的材料和加工要求,磨削相适应的两把刀,并用支紧螺钉1把刀固定在浮动刀排两端,两刀刃的周向尺寸应小于图纸要求尺寸。先松开支紧螺钉8,然后逆时针转动有刻度的螺母6,
In the lathe boring large aperture deep hole, the general use of floating knife row to reduce the vibration of the knife bar and overcome the cutting process to let the knife phenomenon, but the horizontal feed is difficult to control. Therefore, we can fine-tune the trial after the floating knife row, the effect is very good, to ensure the accuracy of parts, and to expand the processing range, easy installation, easy adjustment. Its use is: First, according to the parts of the material and processing requirements, grinding suitable for the two knives, and with a support screw 1 knife fixed at both ends of the floating knife row, the circumferential size of the two blades should be smaller than the required size of the drawings. Loosen the captive screw 8 first, then turn the calibrated nut 6 counterclockwise,
