Nikon XTH 450 for inspecting large and dense parts
The XTH 450 CT (computed tomography) system from Nikon Metrology is said to set a new standard for measurement and non-destructive testing and inspection, especially of turbine blades and cast metal parts. At the core of the system is the in-house-designed, 450 kV micro-focus source (the only one on the market, says Nikon), providing superior resolution and accuracy compared with traditional mini-focus sources.
The system is available with a flat panel or curved linear diode array (CLDA) detector. The latter optimises the collection of X-rays by eliminating scatter phenomena that typically corrupt 2D radiographs of metal parts. Featuring a spot size of 50 to 320 micron (depending on the power), three to eight times smaller than corresponding mini-focus systems, the 450 kV micro-focus source is suitable for the inspection of small, high density parts or castings, including steel and aluminium
