  },
  "summary": "MPF 20000 is a nine-axis CNC airblast system for saturation shot peening and peen forming of aircraft wing skins. The machine coordinates two symmetrical four-axis robot groups, an NC overhead conveyor and closed-loop media generators for large automated components.",
  "sections": [
    {
      "heading": "Large-part handling",
      "paragraphs": [
        "The NC overhead conveyor uses a removable fixturing frame with onboard electric hoists and component-position recognition. The documented work envelope reaches 20 m length, 2.5 m width and 2,000 kg."

    },
    {
      "heading": "Peening architecture",
      "paragraphs": [
        "Two symmetrical four-axis robot groups each carry six pressure nozzles. Their motion can be synchronized for saturation peening, while closed-loop generators regulate air pressure and shot flow.",
        "A camera-based position-scanning system is listed, with optional 3D measurement for additional component-location control."
      ]
    },
    {
      "heading": "Media and enclosure",
      "paragraphs": [
        "The recovery system classifies three media sizes and supports steel balls up to 3.5 mm. The blast chamber uses double lining for acoustic attenuation and pass-through vestibules with retractable sealing brushes and curtains."
      ]
    },
    {
      "heading": "Control and qualification",
      "paragraphs": [
        "Supervision software provides peening, production and maintenance functions. The documented control system cites DMP 28, MIL S 1365 and AMS 2432; production compliance still depends on validated recipes, calibration, media control and customer procedure."
