差动微调镗刀,主要以弹簧力的作用来消除螺纹配合间隙,保证刀头的伸出尺寸准确。经我厂多年生产实践证明,该镗刀调整尺寸精度准确、可靠,操作方便,效果良好。现介绍如下: 1.粗调装置及调整方法粗调整装置由刀盘12和刀套了所组成,粗调是由刀盘和刀套的刻度来实现的。图中刀套装在刀盘中,刀套与刀盘在同一端面上刻有每格1mm的刻度值, Differential fine-tuning boring knife, the main role of the spring force to eliminate the thread with the gap, to ensure that the size of the knife out of the extension accuracy. After years of our factory production practice has proved that the boring knife to adjust the dimensional accuracy is accurate, reliable, easy to operate, the effect is good. Now introduced as follows: 1. Coarse adjustment device and adjustment method Coarse adjustment device consists of cutterhead 12 and a knife cover, coarse adjustment by the cutter and knife scale to achieve. Figure knife set in the cutter, the cutter sleeve and cutter on the same end surface engraved with the value of each 1mm scale,
