简述了DF_(11G)内燃机车整体轮的工作环境及车削加工工艺的重要性。针对该典型难加工材料,通过分析了整体轮材料的化学成分和机械性能,研究了材料的车削和切屑变形机理。并对DF_(11G)整体轮用进口刀具和国产刀具进行车削对比试验。
The importance of the working environment and the turning process of DF_ (11G) diesel locomotive is described briefly. Aiming at the typical difficult-to-machine material, the mechanism of turning and chip deformation of the material was studied by analyzing the chemical composition and mechanical properties of the whole wheel material. And DF_ (11G) the overall round of imported tools and domestic tools for turning comparison test.
