Подготовка к работе эльборововых брусков на медно-оловянной связке

In this video, the presenter demonstrates the preparation of Elborov abrasive blocks for copper‑zinc sharpening. At 00:00 the introduction begins. At 07:20 the visual inspection of new blocks is shown. At 22:54 the equipment used for block preparation is presented. At 40:52 the preparation of a 200/160 µm block is carried out. At 1:03:14 an intermediate microscopy of the 200/160 µm block is performed. At 1:05:15 the preparation continues. At 1:11:33 a visual inspection of the prepared blocks on glass with KК is conducted. At 1:19:05 a few words about bodride are given. At 1:21:36 sequential microscopy of the blocks before and after preparation on glass with KК is shown. At 1:31:38 the blocks are polished on a steel polish. At 1:48:28 a visual inspection of the finished blocks 14/10 and 7/5 µm is performed. At 1:50:24 microscopy of the finished blocks 14/10 and 7/5 µm is shown. At 1:51:47 the final part concludes the demonstration.
