StressX  
Download Brochure
  • Stress-X allows to measure residual stress,providing a through non-destructive analysis of samples of any dimensions thank to the original mounting of the diffractometer head on a 6 anthropomorphic axis robot.
  • The robot and the related measuring head are mounted on a robust trolley made of steel which holds all the control electronics, water cooler for tube cooling and personal computer.
  • It is possible to measure specimens positioned on the measuring platform on board or any other specimen positioned outside of the instrument basement at an optimal measurement distance of 700 mm from the robot centre.
  • Measurement target is defined by a combinationof a Video camera for X-Y pointingand a laser for Z positioning.Laser accuracy is less of 10 microns with ameasuring range of 300+/-70 mm.Thanks to the 6 degree of freedom the measurementpositions and angular ranges arepractically unlimited.
  • Applications :
    • Definition of the quantity of retainedaustenite on bearings and parts of dieselmotor injectors
    • Detection of residual stress on sprocketwheels
    • Detection of residual stress on car motorparts (cam axles, connecting rods, engineshafts, equalisers)
    • Detection of residual stress induced bydeep drawing (household appliances,structural parts)
    • Detection of existing operational stresson gas conducts
    • Detection of operational stress on largetensioned structures
    • Measurement of efficiency of shot-peeningand rolling of components subjectedto stress.
    • detection of residual stress in castings(cast iron parts of tool machines and aluminiumautomotive components)
    • detection of stress induced by (laser andelectron) welding
    • search for a correlation between residual
    • stress and stress resistance of aluminiumalloy car rims
    • optimisation of working parameters forswarf removal to improve the stress resistanceof mechanical components
    • detection of residual stress on helicoidaland leaf springs
    • search for critical zones after applying
    • work loads (arms and aeronautics)
