轮槽铣刀是加工汽轮机轴上叶轮槽的专用刀具,与叶根拉刀相比较,它具有制造简单、成本低、修磨方便等优点。轮槽铣刀由三把或五把铣刀组成一组,本文就三把(粗铣刀、半精铣刀和精铣刀)为一组的轮槽铣刀的制造方法进行了介绍。粗铣刀制造的关键工序是在圆锥面上铣出等导程的螺旋槽。文中介绍了:①等导程锥度螺旋槽铣削过程中的运动及所涉及的公式;②计算方法;③计算举例;④参数的调整。轮槽精铣刀和半精铣刀是铲齿成
Wheel groove cutter is a special tool for machining turbine wheel shaft groove, compared with blade root broach, it has the advantages of simple manufacture, low cost, easy grinding and so on. Wheel groove cutter consists of three or five milling cutter group, this article on the three (rough cutter, semi-fine milling cutter and finishing cutter) as a set of wheel milling cutter manufacturing methods are introduced. Rough cutter manufacturing is the key process of milling the conical surface of the spiral groove. The article introduced: ① other taper spiral groove milling process and the movement involved in the formula; ② calculation; ③ calculation examples; ④ parameter adjustment. Wheel groove milling cutter and semi-fine cutter is a shovel into teeth
