在高温合金涡轮盘中,因为含有高熔点的铬、镍、 钼、钨、锰、钛等化学元素,使这些盘材料的机械性 能值很高,给机械加工带来了很多的困难。而盘的榫 齿拉削更为困难。其中尤以拉削GH1 35盘时的困难最大。现场常遇到以下四个问题: (1)刀具消耗快,耐用度低。粗开槽刀顶刃的两个尖 In the high temperature alloy turbine disk, because of the high melting point of chromium, nickel, molybdenum, tungsten, manganese, titanium and other chemical elements, so that the mechanical properties of these disk material is very high, to the machining of a lot of difficulties. The plate tenon teeth broaching more difficult. Among them, the biggest difficulty in broaching GH1 35 disc. The scene often encounter the following four questions: (1) fast tool consumption, low durability. Roughly grooving the two sharp tips of the blade
