研磨此种平尺的关键,主要是要对修理工具——平板提出一定的要求。即要求它的凸度最好在1μm以内。同时,还应注意操作方式及温度影响。具体做法是:1.假设是300mm平尺,则可用300×300mm以上的研磨平板,以二块一组或三块一组组成。平板先用300mm以上零级刀口平尺,按米字线位置检查平板的平面度。将凹形平板作为下平板、凸形平板作为上平板,用W1.5或W1金刚砂 The key to grinding such flat feet, the main is to repair tools - flat put forward certain requirements. That is, it is desirable that its convexity is within 1 μm. At the same time, should also pay attention to the mode of operation and temperature effects. Specific practices are: 1. Assuming 300mm flat feet, you can use more than 300 × 300mm grinding plate to a group of two or three a group composed. Flat with 300mm above the first zero-level knife flat feet, according to the location of the word meter flatness flatness. The concave plate as the lower plate, convex plate as the upper plate, with W1.5 or W1 emery
