一、加工对象及技术要求 国内、外航空发动机及其引伸产品(燃汽轮机)的封严件普遍采用蜂窝结构。这种结构一般用0.07mm左右厚的镍基合金箔片组合成蜂窝栅格(图1),其大小因机种不同而各异,我公司的蜂窝栅格B=1.57mm。首先,将蜂窝栅格针焊在零件基体的外圆、内圆或平面 First, the processing of objects and technical requirements Domestic and foreign aircraft engines and their extension products (gas turbines) are generally used honeycomb seal. This structure is generally about 0.07mm thick nickel-based alloy foil into a cellular grid (Figure 1), the size of different models vary, my company’s cellular grid B = 1.57mm. First, weld the honeycomb grid to the outer, inner circle, or plane of the part base
