标准化动车组齿轮箱箱体斜油孔加工

Processing Oblique Oil Hole in Standard MU Gearbox Housing

为了减少加工装夹次数、降低生产成本,借助高精度卧式加工中心加工轨道交通齿轮箱箱体,利用数控机床ATRANS、AROT编程指令并借助动力角度头,在标准装夹位置完成了各方位斜油孔加工,在满足加工要求的同时提高了生产效率。

In the process of machining the gearbox housing with high precision horizontal machining center,in order to reduce the frequency of clamping and reduce production costs,we use CNC machine tools′ ATRANS and AROT programming instructions and the power angle head,by which we can achieve the processing of inclined oil holes in specific azimuth in the standard clamping position ,to improve the production efficiency.
