本刊1982年第10期會报道英国航天公司采用由计算机数控机床、自动检验装置和机器人组成的加工单元加工“米兰”导弹发动机壳体的情况。现根据最近的英国期刊进一步介绍该加工单元的上装、工艺与设备,特別是自动检验装置的情况和特点。米兰反坦克导弹发动机壳体采用含硅量高达17％的优质铝合金材料,这种材料虽不难加工,但由于零件形状复杂,壁薄(最后壁厚仅0.9毫米),加工精度高(工件两端的最后直径公差为0.054毫米),加工起来很困难。特
The journal No.10 of 1982 will report that British space company used the processing unit composed of a computer numerical control machine tool, an automatic inspection device and a robot to process the “Milan” missile engine case. According to recent British journals, the processing unit’s tops, workmanship and equipment, especially the automatic test equipment, are further introduced. Milan anti-tank missile engine shell with high silicon content of up to 17% of the high-quality aluminum alloy material, although the material is not difficult to process, but due to complex shape parts, thin wall (the final wall thickness of only 0.9 mm), high precision The final diameter tolerance at both ends is 0.054 mm) and is difficult to machine. special
