我厂为解决大型机床床身导轨的磨削问题,在1969年将一台自制的单柱悬臂式导轨磨床的床身接长了一倍,长达18m。最大磨削长度从原来的6m扩大到14.5m。当时忽视了对原静压供油系统和滑台下部油腔的改善。该机床接长后,滑台每运行到床身的接缝处就出现了颠簸,值达0.12mm左右,严重地影响了加工精度。长期来,这台机床的有效磨削加工长度仍局限于6m的范围内。 1982年,我们结合机床大修,着手对该机床的滑
I plant to solve the large machine bed rail grinding problems, in 1969 will be a self-made single-column cantilever rail grinder bed doubled, up to 18m. The maximum grinding length from the original 6m expanded to 14.5m. At that time, neglected the improvement of the original static pressure oil supply system and the oil chamber in the lower part of the slide table. The machine then long, the slide to the bed every time the joints appeared on the bumps, the value of about 0.12mm, seriously affecting the processing accuracy. In the long run, the effective grinding length of this machine tool is still limited to 6m. In 1982, we combined with the machine overhaul, proceed to the slip of the machine
