今年 ,我厂在生产军工产品９００８０８轻系列薄壁轴承过程中发现 ,由于检测轴承尺寸所用的扭簧式比较仪的测量力不同 ,而使测量同一外径尺寸得出的值不同 ,且测量力越大 ,产生的尺寸偏差越大。经检测发现 ,这种薄壁轴承的壁厚只有２ｍｍ ,如加上一定的测量力（即在检定规程允
This year, I plant in the production of military products 900808 light series of thin-walled bearing process found that due to the detection of bearing size torsion spring comparator used in the measurement of different forces, leaving the measurement of the same diameter size values obtained, and the measurement of force The larger the resulting size deviation is. After testing found that the wall thickness of thin-walled bearings only 2mm, such as with a certain measuring force (that is,
