Diffractometer | Stress X

Overview Stress X diffractometer

Stress X diffractometer allows to measure residual stress, providing a through non-destructive analysis of samples of any dimensions thanks 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 X-ray tube cooling and personal computer.

Robot allows an accuracy in positioning and repeatability of 20 microns.

It is possible to measure specimens positioned on the measuring platform on board or any other specimen positioned outside of the instrument basement at optimal measurement distance of 700 mm from the robot centre.

Measurement target is defined by a combination of a Video camera for X-Y pointing and a laser for Z positioning.

Laser accuracy is less of 10 microns with a measuring range of 300+/-70 mm.

Thanks to the 6 degree of freedom the measurement positions and angular ranges are practically unlimited.

The device is typically used

  • definition of the quantity of retained austenite on bearings and parts of diesel motor injectors
  • detection of residual stress on sprocket wheels
  • detection of residual stress on car motor parts (cam axles, connecting rods, engine shafts, equalisers)
  • detection of residual stress induced by deep drawing (household appliances, structural parts)
  • detection of existing operational stress on gas conducts
  • detection of operational stress on large tensioned structures
  • measurement of efficiency of shot-peening and rolling of components subjected to stress
  • detection of residual stress in castings (cast iron parts of tool machines and aluminium automotive components)
  • detection of stress induced by (laser and electron) welding
  • search for a correlation between residual stress and stress resistance of aluminium alloy car rims
  • optimisation of working parameters for swarf removal to improve the stress resistance of mechanical components
  • detection of residual stress on helicoidal and leaf springs
  • search for critical zones after applying work loads (arms and aeronautics)
