我院附属工厂有一台M7130平面磨床,年久失修,磨削质量明显下降。79年对这台磨床进行大修,同时,对磨头主轴轴承进行改装,采用小孔板式节流静压轴承. 磨床改装后,磨削质量大为提高。采用白刚玉80号粒度的砂轮,对淬火钢(HRC50～55)进行试磨,表面光洁度达▽10c。对450×250大平面进行试磨,经我院精密测量试验室鉴定,表面光洁度达到▽10b,整个平面光洁平整,并且无明显波纹,比原来机床磨削表面光洁度提高两级.改装后.经过三年多的生产使
Affiliated factory in our hospital has a M7130 surface grinder, disrepair, grinding quality decreased significantly. 79 years to overhaul the grinder, at the same time, grinding head spindle bearings are modified, the use of orifice plate throttling hydrostatic bearings grinder modified, the grinding quality greatly improved. Using white corundum size 80 grinding wheel, hardened steel (HRC50 ~ 55) for trial grinding, the surface finish of ▽ 10c. 450 × 250 large plane for trial grinding, the precision measurement laboratory in our hospital identified the surface finish to ▽ 10b, the entire plane smooth and smooth, and no obvious ripples, than the original machine grinding surface finish increased by two. More than three years of production
