本文提出用硬质合金刀具,高速铣削的新工艺加工花键轴。并且以精铣代磨,通过该厂两年的生产实践效果比较好,降低了成本,提高了效率,提高了质量。本文对一般工厂、修理厂有启发作用,对大厂也有可借鉴之处。 In this paper, the spline shaft is machined by the new technology of carbide cutting tools and high speed milling. And refined milling, through the plant two years of production practice is better, reduce costs, improve efficiency and improve quality. This article on the general factory, repair shop inspired by the manufacturers can also learn from.
