在毛主席革命路线指引下,我厂广大革命职工,发扬“自力更生,艰苦奋斗,破除迷信,解放思想”的革命精神,经过一年多的努力,反复进行研究试验,终于试制成了新型的、一次积分式的 GJD-5型光洁度测量仪。这种新产品为工业生产和科学实验的测试工作,提供了有利条件。GJD-5型表面光洁度测量仪是中等精度的、针描式的、采用压电晶体作为传感器的表面光洁度测量仪器。这种仪器可对经机械加工后零件表面的光洁度进行测量。本仪器有六个量程,可测量6～12级的表面光洁度(即2.5μ
Under the guidance of Chairman Mao’s revolutionary line, the vast revolutionary workers in our factory carried forward the revolutionary spirit of “self-reliance, arduous struggle, superstitious belief and emancipation of the mind.” After more than a year of hard work and repeated research and experiments, we finally made a new type of , An integral GJD-5-type finish meter. This new product provides favorable conditions for the testing of industrial production and scientific experiments. GJD-5 surface finish measuring instrument is a medium precision, needle-like, surface finish measuring instrument using a piezoelectric crystal as a sensor. This instrument measures the finish of machined part surfaces. The instrument has six ranges, measuring 6 to 12 surface finish (that is, 2.5μ
