大量块(尤其是一米以上的)经过一段使用容易产生变形而不易修复,直接影响精度。我们根据本厂检定仪器和精密测量的需要,对原来5等(800、1000 m(?))大量块采用滚压法对变形进行调正,经过几年时间证明效果较好。调正方法:将检定后的量块凸面(正值部位)向下放在平板上,手持滚压工具,(用十七号左右的小轴承压入工具钢制做的滚轮,将
A large number of blocks (especially one meter or more) are prone to deform after a period of use and are not easily repaired, directly affecting the accuracy. According to the requirements of our factory for checking instruments and precision measurement, we adjusted the deformation by a rolling method on a large number of blocks of the original 5 (800, 1000 m (?)), Which proved to be effective after several years. Adjustment method: the test piece convex (positive position) down on the flat, hand-rolled tools, (with a small bearing on the 17th or so into the tool made of steel roller, the
