我厂在改造旧没备中,机动科与工具车间合作,大搞三结合,应用静压技术,把一台技术状况最差的旧M 120 W磨床,改装为液体静压轴承,机床性能得到很大提高,旧磨床改造成为高精度磨床(我们称MG 120 W磨床)。改装后的效果机床改装后,轴承刚性强;主轴旋转精度高。因此,磨削加工精度及光洁度显著提高。机床主轴的耐用性也很好。机床改装后与改装前,几个主要性能比较,见表。
I plant in the transformation of the old equipment, motor and tool shop cooperation, engage in a combination of three, the application of static pressure technology, the worst technical condition of the old M 120 W grinder, hydrostatic hydrostatic bearings modified machine tool performance obtained Greatly improved, old grinder transformed into a precision grinder (we call MG 120 W grinder). After the effect of modified machine modification, the bearing rigidity; spindle rotation accuracy. Therefore, grinding precision and finish significantly improved. The durability of the machine spindle is also good. Machine modification and modification before, several main performance comparison, see table.
