Stress X provides a non-destructive test of a sample. The head of the diffractometer is mounted on an anthropomorphic 6 axis robot that allows to analyze samples of any dimensions and shapes
StressX could be used in a closed cabin as laboratory analysis or on a four-wheel trolley for on-site analysis
The StressX provides a flexible solution to residual stress (that could be induced by machining, grinding, rolling, deep drawing, welding, thermal hardening and shot peening) determination on samples of any dimensions by the original synergy between compact X ray diffractometer and 6-axis robot to prevent fatigue damage and to control material’s durability and safety
6-axis robots are available with positioning accuracy and repeatability as low as 20 µm and positioning range as high as 895 mm radius from robot center. Thanks to the 6 degree of freedom the measuring positions and angular ranges are only limited by robot size
Measuring target is defined by a combination of a Video camera for X-Y pointing and a laser for Z positioning. Laser accuracy can be less than 10 µm and measuring range can be as high as 300 mm from the goniometer center
