摘要：【中文】本发明公开了一种提取陶瓷结合剂CBN砂轮中磨料的方法，将砂轮高温灼烧，再迅速降温，然后将砂轮放入球磨机中带水进行球磨，将粉末放入装有自制溶液的塑料瓶中，密封。用恒温振荡器进行震荡，再放入超声波清洗机中。纯水过滤成中性，然后，将粉末放入氢氧化钾溶液中，放入恒温振荡器中震荡。再放入超声波清洗机中清洗。纯水过滤呈中性。烘干。用分样筛分样。不同粒度分类收集。本发明提取周期短，提取效率高。不影响磨料的二次使用。 【EN】The invention discloses a method for extracting abrasive from a ceramic bond CBN grinding wheel, which comprises the steps of firing the grinding wheel at high temperature, rapidly cooling, putting the grinding wheel into a ball mill for ball milling with water, putting powder into a plastic bottle filled with a self-made solution, and sealing. Oscillating by a constant temperature oscillator, and then putting into an ultrasonic cleaning machine. Filtering pure water to neutrality, adding the powder into potassium hydroxide solution, and shaking in a constant temperature oscillator. Then putting the mixture into an ultrasonic cleaning machine for cleaning. The pure water is filtered to be neutral. And (5) drying. And screening the sample by using the sample. And (4) classifying and collecting different particle sizes. The invention has short extraction period and high extraction efficiency. The secondary use of the abrasive is not influenced.
