普通车床床鞍溜板在切削压力和溜板箱重力的双重作用下,承受一个很大的翻转力短,使床鞍溜板动态刚度不稳定,并危及整个刀架系统。为了减少这种现象并提高整个刀架系统刚性与精度,提出下列几点建议,供设计师们参考。 1.如图1所示,在三杠下部增加一条纵向辅助导轨,在溜板箱左右两 Ordinary lathe saddle slipper under the dual action of cutting pressure and slide box gravity, bear a large turning force short, make saddle slide dynamic stiffness unstable, and endanger the entire tool holder system. In order to reduce this phenomenon and improve the rigidity and accuracy of the entire tool holder system, the following suggestions are made for designers’ reference. 1. As shown in Figure 1, add a vertical auxiliary rail in the lower part of the third bar, left and right in the slide box
