我们自制了一组(25～175mm)可调式千分尺研磨器,经过几年来的使用,认为只要制造精度达到设计要求,研磨出来的千分尺平行度和平面度均可达到规程要求。 0～25mm的千分尺仍然采用四根不同尺寸的研磨器,25～50mm以上的千分尺研磨器可作成空心的可调式的,即原来每组四根作成一组一根。经过螺母调成四个不同尺寸,相差为0.125mm,即使千分尺研磨器磨损很多,调 We made a group of self-made (25 ~ 175mm) adjustable micrometer grinders. After several years of use, we believe that as long as the manufacturing precision meets the design requirements, the parallelism and flatness of the micrometers polished can meet the requirements. 0 ~ 25mm Micrometers still use four different sizes of grinder, 25 ~ 50mm above the micrometer grinder can be made hollow adjustable, that is, each of the original four into a group. After the nut transferred into four different sizes, a difference of 0.125mm, even if the micrometer mill worn a lot, tune
