美国 SSP 产品公司采用五台积木式专用机床加工导弹发射架,不仅保证了极高的加工精度,而且取得了良好的技术经济效果。导弹发射架是由几个大型铝焊件组成,每个焊件的尺寸约为60英寸×40英寸(152.4厘米×101.6厘米),重480磅(217.7公斤)。因为焊件形状特殊,需要加工的表面种类和数量较多,又要求极高的精度,因此加工很困难。 US SSP product company uses five blocks of special-purpose machine tools for missile launchers, not only to ensure the high precision, and achieved good technical and economic results. The missile launcher is made up of several large aluminum weldments, each measuring about 60 inches by 40 inches (152.4 cm by 101.6 cm) and weighing 480 pounds (217.7 kg). Because of the special shape of the weldment, the type and amount of the surface to be machined are much larger and require very high precision, the machining is difficult.
