近年来,为应对飞机发动机透平叶片冷却孔加工的需求,日本ELENIX公司(本刊曾在2012年第13期中做过介绍),三菱电机公司、牧野公司、英国Winbro公司先后研制出了新型高速、高品质多轴、专用的电火花加工机以及激光加工与电火花加工相复合的加工机。在此,拟对相关的报道作一个介绍,以供参考。气体发动机或喷气发动机所构成的零件,其动叶片与固定叶片(见图1),一般皆利用镍基耐热合
In recent years, in order to cope with the machining requirements for turbine blade cooling holes in aircraft engines, Japan’s ELENIX Company (we published in the 13th issue of 2012), Mitsubishi Electric Corporation, Makino Corporation and Winbro Company of the United Kingdom have successively developed the new high- , High-quality multi-axis, dedicated EDM machines and laser processing and EDM complex processing machine. Here, we intend to make a presentation about the relevant reports for reference. Gas engine or jet engine parts, the rotor blades and fixed blades (see Figure 1), are generally used nickel-based heat-resistant
