牛头刨床、龙门刨床和其它有垂直升降刀架的机床,都存在着一个刀架落刀问题。我们要求刀架在下降时严格按传动比进行,但实际上刀架往往在一瞬间多下降了一段距离,有时丝杆根本未转动,由于震动,刀架也下冲一段距离。这种现象,就是我们常说的“刀架落刀”。 Shaper, planer and other machines with vertical lifting turret, there is a turret knife problem. We asked the turret to descend strictly in accordance with the transmission ratio, but in fact the turret often more than a moment in the decline of a distance, and sometimes the screw did not rotate, due to vibration, turret also under the red for some distance. This phenomenon is what we often say “knife knife.”
