铣床工作台采用丝杠副垂直升降机构,常会 遇到升降手柄操纵力过大超过标准的问题。如 X 62 W铣床,为了改善升降丝杠副的结构性能, 达到手摇轻便,自锁可靠的目的,我们设计制造了 一种滚动螺母,以取代原来的滑动升降螺母,应 用在X 62 W, X 52 k和 X53 k铣床上。改装前,上升操纵力 Milling machine table with screw vertical lifting mechanism, often encounter the lifting handle operating force is too large over the standard problem. Such as the X 62 W milling machine, in order to improve the structural performance of the lifting screw pair, achieve the purpose of hand-light, self-locking and reliable, we designed and manufactured a rolling nut to replace the original sliding nut for X 62 W, X 52 k and X53 k milling machines. Before modification, increase the control
