我所研制了多种精密测试仪器,随着仪器精度的不断提高,对机械零部件的精度不断提出更高的要求。例如,各种精密轴系要求高精度的轴和轴套,高精度的直线运动要求高精度的直线导轨。为适应达一需要,近年来我所轴、轴套和直线导轨等精密零件的精加工技术 I have developed a variety of sophisticated test equipment, with the continuous improvement of precision instruments, the accuracy of the mechanical parts continue to put forward higher requirements. For example, various precision shaft systems require high-precision shafts and bushings, and high-precision linear motion requires high-precision linear guides. In order to meet a need, in recent years, my shaft, bushings and precision parts such as linear guide finishing technology
