Paper pulp binder CBN grinding wheel and preparation method thereof
The invention discloses a paper pulp binder CBN grinding wheel and a preparation method thereof. The paper pulp binder CBN grinding wheel is prepared from, by mass, 20-30 parts of paper pulp, 10-20 parts of silicon dioxide, 5-12 parts of aluminum oxide, 6-12 parts of high-alumina cement, 5-14 parts of zinc oxide, 0.4-0.8 part of manganese dioxide, 8-13 parts of calcium bicarbonate, 3-8 parts of silicon nitride and 10-14 parts of sodium phosphate. The materials are mixed and then subjected to hot press molding to form the grinding wheel, and the granularity of the diamond is 250 meshes. According to the formula, the ingredients are reasonable, the uniformity of the manufactured grinding wheel forming material is good, the grinding wheel has higher toughness and longer service life, and the cost is high, but precious workpieces needing to be finely machined can be ground.
本申请公开了一种纸浆结合剂CBN砂轮及其制备方法，由以下质量份数配比的组分制成：纸浆20‑30份、二氧化硅10‑20份、三氧化二铝5‑12份、高铝水泥6‑12份、氧化锌5‑14份、二氧化锰0.4‑0.8份、碳酸氢钙8‑13份、氮化硅3‑8份和磷酸钠10‑14份。上述材料混合以后经过热压成型为砂轮，金刚石的粒度为250目；本配方配料合理，制作的砂轮成型料均匀性比较好，砂轮有更强的韧性和更高的寿命，虽然成本较高，但是可以磨削贵重和需要精致加工的工件。
