如图是上海量具刃具厂用机械性能较好的65号钢经热处理,镀铬等精加工制成的新型间隙卷尺,全尺的平直度为0.04mm,测量范围为0.1～5mm,任选读线误差<0.024mm,尺面上每格示值为0.05mm,尺端有吊孔,随身携带灵巧方便。新型间隙尺在使用时只要将尺直接插入间隙,从读值线上能直观地读出间隙的大小,令人一目了然;由于该尺最大测量值为5mm,当遇有较大间隙时也
As shown in Figure Shanghai Measuring Tool & Cutting Tool Plant with better mechanical properties of steel 65 after heat treatment, chrome and other finishing made of new gap tape measure, full-scale flatness of 0.04mm, the measurement range of 0.1 ~ 5mm, optional reading Line error <0.024mm, the ruler on each grid value of 0.05mm, feet hanging hole, portable dexterity and convenience. The new gap ruler in use as long as the ruler directly into the gap, from the reading line can visually read the size of the gap, it is clear at a glance; the maximum measurement of the ruler is 5mm, in the event of a larger gap
