砂轮修正,过去一直都习惯于采用大颗粒金刚钻,但价格昂贵,而且依赖进口。在批林批孔的大好形势下,上海钻石工具厂,利用价廉的小颗粒金刚钻,压制成一种钻石片状修正器,来代替大颗粒金刚钻,用于砂轮修正。这不仅有现实的经济意义,而且有深远的政治意义。但是,由于条件所限,我们的试验做得较少,这些数据尚不足以引出规律性的结论。现在就我们有限的试验,提出我们的看法,仅供参考。
Grinding wheel correction, the past has always been accustomed to using large-grain diamond, but expensive, but also dependent on imports. In the good situation approved Lin holes, the Shanghai Diamond Tools Factory, the use of inexpensive small diamond particles, pressed into a diamond flake corrector to replace the large diamond particles for wheel correction. This not only has realistic economic significance, but also has far-reaching political significance. However, due to the limited conditions, our trials have done less, and these data are not enough to draw the conclusion of regularity. Now, with our limited experiments, put forward our opinion for reference purposes only.
