摘要
以磨削加工汽车发动机凸轮轴、曲轴为例,对陶瓷CBN砂轮与普通刚玉砂轮进行了加工效果对比。结果表明:高速陶瓷CBN砂轮的耐用度是普通陶瓷刚玉砂轮的100倍,寿命是普通砂轮的的44.4倍,而原材料消耗仅为其1/56;加工相同的工件数量,使用刚玉砂轮进行加工,磨料消耗是高速CBN砂轮的400余倍;采用高速陶瓷CBN砂轮代替刚玉砂轮可提高生产效率30%以上,综合生产成本比刚玉砂轮磨削降低60%。高速CBN砂轮具有高效率、高精度、低磨削成本,低环境污染的技术优势,其代表了当今世界磨具产品发展的一个主要方向,是实现绿色加工目标的有效手段。
In this study, the vitrified bond CBN wheels are compared with the conventional corundum wheels in the grinding of automotive engine camshaft and crankshaft. The results show that the durability of the high speed vitrified bond CBN wheels is 100 times that of the conventional corundum wheels, and its service life is 44. 4 times that of the conventional corundum wheels, but the raw material consumption is only 1/56. When in the same amounts preparation, the abrasive consumption of using corundum wheels is more than 400 times that of the high speed vitrified bond CBN wheels. When the conventional corundum wheels are replaced by the high speed vitrified bond CBN wheels, it would improve production efficiency more than 30G and save more than 60% production cost. The high speed grinding wheel is an environment-protection products with high precision, high efficiency, low production costs, less environment pollution, which make it be a sharp weapon for realizing the target of green process.
