我厂自制简易滚刀磨床所需要的高精度分度板,本着“自力更生、奋发图强”的精神,经过二周的努力,在一般设备条件下,通过改进工具,制成两块分度板。这两板分度板经检验,相邻误差不超过10微米,最大累积误差不超过20微米,符合图纸设计要求。现将钳 I plant self-made simple hob grinding machine required high-precision indexing plate, in the spirit of “self-reliance, work hard”, after two weeks of hard work, under general equipment conditions, through the improvement of tools, made two indexing board. The two boards indexing board after testing, the adjacent error of not more than 10 microns, the maximum cumulative error of not more than 20 microns, in line with the design requirements of the drawings. Now the clamp
