静压轴承薄膜反馈器的淬硬薄膜钢片(图1)的精度要求高,为了磨出合格的薄膜片,除了选用精密的机床和合适的砂轮,掌握正确的砂轮平衡和修整方法,以及控制热处理淬火变形量及应力变形外,我们还使用了特意设计的薄膜平磨夹具(图2),取得较好的效果。现将有关夹具的设计使用特点介绍 The hydrostatic bearing film feedback hardened film steel (Figure 1) high precision requirements, in order to grind qualified film, in addition to the selection of precision machine tools and grinding wheel, master the correct wheel balance and trimming methods, and control Heat treatment of quenching deformation and stress deformation, we also used a specially designed film flat grinding fixture (Figure 2), and achieved good results. Now the design of the use of fixture features introduced
