万能工具显微镜是各生产厂家计量室主要精密检测仪器之一。五、六十年代韵万能工具显微镜,光学座标已不清晰,导轨磨损,精度严重丧失;新购置的光学座标万能工具显微镜,精度也只能达±3μm。成都工具研究所研制的光栅微机系统给用户带来福音。老的万能工具显微镜装上光栅微机系统,精度可达±1.5μm,检测效率可提高3～10倍,并能大大减轻检测人员的劳动强度,用户已获明显的效益。 Universal tool microscope is the manufacturer of measuring room one of the major precision testing equipment. Five or sixty years rhyme universal tool microscope, the optical coordinates are not clear, rail wear, loss of precision; newly purchased optical coordinates universal tool microscope, the accuracy can only reach ± ​​3μm. Grating Computer System developed by Chengdu Tool Research Institute brings good news to users. The old omnipotent tool microscope with grating computer system, the accuracy of up to ± 1.5μm, detection efficiency can be increased by 3 to 10 times, and can greatly reduce the labor intensity of the inspectors, the user has been significantly effective.
