In industries such as aerospace, automotive, rotary machinery and bio-medical, finding and accurately measuring surface defects on precision surfaces is critically important for performance and longevity. A small pit may concentrate stress that leads to severe damage or component failure. A bump or burr on a mating surface may damage its mating component, leading to leaks, squeaks, heat build-up, etc.
Despite the critical importance of accurately gauging surface defects, much surface inspection is still completed using low-repeatability visual inspection, or low sampling techniques such as scribe gauges or stylus profilers.
The 4D InSpec Surface Gauge is the world’s first instrument for handheld, high resolution measurement of surface defects and fine features. Accurate, flexible and affordable, the 4D InSpec takes high resolution measurement out of the metrology lab and puts it where it is most needed: on the factory floor, in refurbish/rebuild facilities, and in the field.
