Application of spinning process (2)

      Almost all American aircraft and engine manufacturing companies are equipped with metal spinning machines and have been used in production. The earlier adopting this process was Pratt Whitney.

    Aeronautical parts manufactured by the spinning process include: turbine shaft, compressor shaft, inlet cone, and tail vein of the nozzle. Combustion chamber bushings, bearing supports. The pipe used for the compressor casing and the nozzle of the 75-type jet engine is a thin-walled pipe in which a blank having an inner diameter of 2958 mm, a length of 1,143 mm, and a wall thickness of 6.2 mm is spun. The composite parts used in the jet engine have a cylindrical outer diameter of 55 mm, a length of 541 mm, a wall thickness of 1.14 to 0.89 mm, a cone portion diameter of 390 mm, and a total length of 967 to 968 mm.

[Weapon production]

    In the United States, the metal spinning process is used to manufacture the armor-piercing projectile. The Rohr Meite large spinning machine (bed length 7.62m) has been modified to rotate the barrel with an outer diameter of 101~305mm and a wall thickness of 50mm. It is also expected to unscrew large thick-walled pipe fittings with an inner diameter of 178 mm and a wall thickness of 101 mm.

[Civil Industrial Mode]

    The first large-scale application of metal spinning was the manufacture of discs for cream separators. After the Second World War, the spinning process produced a television display tube, and later produced kettles, cups, measuring cups, beer kegs and funnels, cones, milk cans, round pots, washing drums, and gas. Bottles, truck shaft discs, hydraulic cylinders, fire extinguishers, and the production of pressure tanks with oil tanks, boiler heads, pressure bottles, musical instruments and various honors.
