Robotic Peening Machine

Sinto America’s robotic peening machine is based on a 6-axis robot, manipulating a pressure-blast shot peening system. The machine includes a 24” diameter rotary indexing table which can be controlled as a 7th axis of robotic motion.  This system minimizes floor space utilization and designed for ease of maintenance and calibration functions, utilizing Sinto’s years of shot peening experience. This new compact machine design enables inexpensive transportation as well as fast installation and start up at the customer’s facility.


  • Off-line programming using solid modeling similar to CAD/CAM systems
    • 3D simulation with chamber, table , nozzles, and parts to test run parts for verification of the following:
      • Nozzle tool path for coverage mapping
      • Nozzle to Part Impingement Angle
      • Nozzle to Part Stand-Off distance
      • Potential interference between part and machine
      • Off line programming with the part drawing will prevent the potential for interference between the part and machine
      • Clearance for tooling & chamber
      • Successful Program execution with ancillary devices such as air blow-off or automatic door/unload features
  • Superior Flexibility using Sinto’s quick-change media system
      • Pressure vessel drain system
        • Pressure Vessel Drain Valves
        • Removable storage containers
      • Quick-change classification system
        • Easy access to screen decks
        • Quickly change screen to match media size
      • Programmable Logic Controller (PLC) with Human Machine Interface (HMI) system
        • Multiple media recipes for Magna-Valve calibration
        • Media monitoring with automatic filling chamber to eliminate over-filling and low shot alarms during cycle.
        • Warning message with indicator of low media levels due to obstruction or failed component (media delivery > media recovery) to prevent in-process faults
  • Rotary air lock for media recovery.
  • Ergonomic part load/unloading via notched chamber and door.
  • Multi-sized media delivery bulkhead for efficient routing of all media delivery hoses entering the processing chamber.
    • Chamber wall is fitted with manifold for a range of all common hose diameters
    • Ensure hoses are neatly & safety routed inside and outside of the chamber for easy maintenance.
    • Improved ease of maintenance due to ergonomic design
  • Optional Stress Measurement and Part inspection available using Sightia Integration
