我厂大型捷克进口W250HC铣镗床采用静压导轨,滑座与导轨在压力油膜为0.02～0.03mm间隙上浮起,因不产生摩擦,运行平稳,数显表显示一直稳定。1995年1月,机床在运行时,X轴向移动中数显表突然出现跳动,在滑座移动时跳动显示值为0.30～0.40mm,导轨产生爬行。我们检查静压液压系统均无问题,最后分析可能是床身导轨水平几何精度发生了变
Our factory imported Czech W250HC milling and boring machine hydrostatic guide rail, slide and guide rail in the pressure oil film for the 0.02 ~ 0.03mm gap up, because it does not produce friction, smooth operation, digital display has been stable. January 1995, when the machine tool is running, X-axis movement in the digital display suddenly beating, when the slider beats move display value 0.30 ~ 0.40mm, crawling crawl. We check the hydrostatic pressure system are no problem, the final analysis may be the horizontal geometry of the bed rail variable has changed
