涡轮叶片榫齿采用缓进磨削加工,以代替传统的铣削加工,是七十年代的事。在磨削中,如果一次磨削量过大,工件表面会出现烧伤,在加工热导性不好的耐热合金时尤为明显。这是影响这种新工艺进一步提高效率(单位时间内的金属去除率)的主要原因。七十年代后期,人们对此进行了探讨,发现修正过的砂轮,进入磨削的前40秒钟内,磨
Turbine blade tenon teeth using slow grinding, instead of the traditional milling, is the seventies thing. In the grinding, if a grinding amount is too large, the workpiece surface will burn, in the processing of poor thermal conductivity of the heat-resistant alloys is particularly evident. This is the main reason that affects the new process to further improve the efficiency (metal removal rate per unit time). The late seventies, people have discussed this, found that the modified wheel, into the first 40 seconds of grinding, grinding
