Main equipment required to process typical parts of aircraft fuselage

(1) Three-axis machining center, such as large gantry vertical machining center;

(2) Five-axis linkage machining centers, such as large gantry vertical machining centers, shall be equipped with A/B swing angle milling heads or A/C swing angle milling heads;

(3) From the perspective of development, a large gantry-type dual-spindle five-axis machining center is required, and the table size is 5m×20m for processing beam parts;

(4) Processing of aluminum alloy parts requires high-power high-speed machining center, power ≥40kW, spindle speed of 20000r/min or more, with two-axis swing angle milling head;

(5) Due to the large amount of cutting of the whole aluminum alloy parts, in order to facilitate chip removal, it is better to require a horizontal machining center where the table can be turned over 90°. At present, there is no such horizontal machining center in China;

(6) There are many types of aircraft fuselage structural parts, different shapes, and poor process rigidity, which requires a large number of fixtures. In order to reduce costs and shorten the production preparation cycle, various flexible fixtures are required;

(7) Sheet metal forming parts mainly involve the forming of skins such as skins, profiles and pipes, and require precise forming. In order to ensure the manufacturing precision, a large-size skin stretching machine, a skin roll forming machine, a three-axis rolling leveling machine, a profile bending machine, and a duct forming machine are required. Aircraft parts assembly also requires automatic drilling and riveting equipment;

(8) In order to reduce the weight of the aircraft, the application of composite materials is more and more, and the production of composite components requires a tape laying machine, etc.
