前言我厂原来技术力量薄弱,对于高精度零件的加工十分缺乏经验,近几年来,为了落实毛主席关于“备战、备荒、为人民”的教导,我们从事了军工生产,并研制了精度在1″平行度的石英反光镜、N=0.2光圈的平行度为5″的滤色镜及塔差≤5″的大型五角直角棱镜等各种平面零件及棱镜零件。在加工这些零件中,依照我厂的生产技术情况和特点,根据自己的水平,在兄弟单位的启发帮助下,自己建立了一套适合我们情况的加工上述平面组成的高精度零件的工艺,现将体会分述如下。加工高精度平面零件注意的问题有三个主要方面,即光圈、角度及检验。为了解决这三
In the past few years, in order to implement Chairman Mao’s teachings on “preparing for war, preparing for waste and serving the people”, we engaged in the production of military industry and developed a system with an accuracy of 1 “Parallelism of the quartz mirror, N = 0.2 aperture parallel to 5” color filter and tower difference ≤ 5 "large pentagonal rectangular prism and other flat parts and prism parts in the processing of these parts, in accordance with our factory’s Production technology and characteristics, according to their own level, inspired by the fraternal units, set up a set of their own situation for the processing of the above-mentioned plane composed of high-precision parts technology, the experience will be divided as follows. Processing precision plane There are three main aspects to the problem of parts attention, namely aperture, angle and inspection. In order to solve these three
