我們看到一种国外資料,参照它的原理,加以改进,設計了一种簡单金相試驗样品抛光的夹具,試用証明效果良好,完全摆脫手工操作,大大提高生产率,避免絨布的撕破,抛光质量較高。現介紹如下,供同志們参考。整个夹具形状見图。在抛光盘(1)上放轉子(2),其直徑小于或等于抛光盘的半徑。轉子中心钻孔和軸(3)組合,軸(3)穿过横梁(4)并用一肖子固定,横梁(4)用支柱(5)支在抛光桌上。由于轉子的自身重量和抛光盘产生一定摩擦,又由于A、B两点綫速度不等,故轉子和地球一样,将一面
We see a foreign material, with reference to its principle, to be improved, designed a simple metallographic test sample polishing fixture, the trial proved good results, completely out of manual operation, greatly improving productivity, to avoid flannel tear , Polishing quality is higher. Now introduced as follows for comrades reference. The entire fixture shape see figure. The rotor (2) is placed on the polishing disc (1) and its diameter is less than or equal to the radius of the polishing disc. The center of the rotor is drilled and the shaft (3) is combined. The shaft (3) passes through the beam (4) and is fixed with a shank. The beam (4) is supported on the polishing table by the column (5). As the rotor’s own weight and polishing disc have a certain friction, but also because of A, B two-point line speed, so the rotor and the Earth, will be one side
