嵌有较硬杂质量块工作表面修复技术胡国金（常州市计量测试技术研究所，常州２１３００１）量块是由两个相互平行的测量面之间的距离来确定其工作长度的高准确度量具，在使用过程中，经常会发生嵌有较硬杂质（如人造金刚石颗粒等），对于这类量块检修时，仅用常规的干研法... Embedded with hard impurity block work surface repair technology HU Guo-jin (Changzhou Institute of Metrology Technology, Changzhou 213001) Gauge block is a high-accuracy measuring tool whose working length is determined by the distance between two mutually parallel measuring surfaces. In the process of using, often occur embedded hard impurities (such as synthetic diamond particles, etc.), for the maintenance of such a block, only the conventional dry method ...
