多年来,我们已经研制出一批高精度丝杠,已分别安装在长春光机所和北京、上海、天津等地光学工厂的光栅刻划机上,这些光栅刻划机都刻制出了质量优秀的光栅。这些经仔细修研的高精度分距丝杠,其精度实测结果为:周期误差小于0.02微米;累积误差在200毫米内小于0.16微米;螺纹与两端轴颈的不同心度小于0.1微米;丝杠两端轴颈的不同心度小于0.15微米。制造这些高精度丝杠时,在分距丝杠的设计、丝杠材料的选择、丝杠的热处理、丝杠的机械加工、丝杠的研磨和丝杠的检验等
Over the years, we have developed a number of high-precision lead screw, which have been installed in Changchun Institute of Optical and Beijing, Shanghai, Tianjin and other optical factory grating grating machine, the grating engraving machine are engraved with excellent quality Raster. These carefully researched high-precision pitch screw, the accuracy of the measured results: the cycle error of less than 0.02 microns; cumulative error less than 0.16 microns within 200 mm; thread and both ends of the journal less concentricity of less than 0.1 microns; silk The misalignment of the journals at both ends of the bar is less than 0.15 microns. When manufacturing these high-precision lead screws, the design of lead screws, the selection of lead screws, the heat treatment of lead screws, the machining of leadscrews, the grinding of leadscrews and the inspection of leadscrews
