随着各行各业的发展,对砂轮的要求也越来越高,新的砂轮标准对砂轮的几何尺寸作了更加严格的规定,例如以前砂轮厚度允差是0.5毫米,用钢板尺来检测还勉强可以,现在要求小于0.3毫米,这样钢板尺就无能为力了。如果换用卡尺,测量精度可以提高,但因其测量面很小,读数也很不方便,又给维修带来很多麻烦。为了解决这个问题,我们利用废千分尺和旧百分表组合改制成一种测量砂轮厚度的专用量具。
With the development of all walks of life, the requirements of the grinding wheel is also getting higher and higher, the new wheel standard on the geometry of the wheel made more stringent requirements, such as the previous wheel thickness tolerance is 0.5 mm, with steel ruler to detect Barely can now require less than 0.3 mm, so the steel ruler can do nothing. If you switch to the caliper, measurement accuracy can be improved, but because of its small measuring surface, the reading is also very inconvenient, but also to bring a lot of maintenance trouble. In order to solve this problem, we use the waste micrometer and the old dial indicator combination into a measure of the thickness of the wheel special measuring tools.
