The 4D InSpec was designed with field maintenance applications in mind. Use the gauage to measure large components such as casings and housings, directly on the part. Measure surfaces on components with complex geometries such as turbine blades and firtree roots, even blind features and holes, all with micro-meter resolution.
Accurate measurement of surface defects on turbine blades, fir-tree roots and other structures is critical to long component life and safe operation. The 4D InSpec can instantly measure features and defects from 0.1–100 mils deep on parts with challenging geometries.
The 4D InSpec brings high resolution measurement to the factory floor, making it possible to locate and measure pitting, scratches and other defects, as well as measuring dot peening, laser scribe marks, edge break and other features. 4D InSpec is more accurate than optical comparators, helping to correctly identify parts that do not meet surface texture specifications, while eliminating the waste of scrapping or reworking components that actually pass all requirements.
The 4D InSpec also excels at quantifying wear and corrosion on components during rebuilds, letting you measure with micrometer-level resolution in even the toughest environments.
4D InSpec's can measure pits, scratches, dents, corrosion and other defects and features on large and small engine components. Measure dot peen and laser scribed markings and other fine part features as well, on shafts, mating surfaces, valves, cylinder walls, etc.
To measure defects on large or complex components inspectors are faced with a dilemma. Handheld depth gauges are quick and portable, but they lack the resolution to make repeatable measurements. High resolution systems are typically confined to a stand in a metrology lab. In order to measure large components the surface must be replicated using rubber or silicone, a lengthy, messy process.
The 4D InSpec Surface Gauge was designed to provide portable, high resolution measurement wherever it is needed on the shop floor. Its unique design allows inspectors to measure defects in corners, on radii, under flanges, and across large surfaces—effectively making replication a thing of the past. A fold mirror attachment allows measurements in extremely narrow areas or inside of bores, where even replication would prove difficult.
Left unchecked corrosion can impede performance and can lead to component failure, sometimes with catastrophic results. Inspectors must be able to accurately determine the severity of corrosion to ensure part performance. But visual inspection is very open to interpretation, and high resolution, quantitative metrology systems are too expensive, too susceptible to vibration, and too size limited for shop use.
The 4D InSpec Surface Gauge instantaneously calculates the depth, width and volume of all corrosion pits within the field of view. An inspector can quickly measure large portions of a component for a thorough, accurate assessment of the severity of corrosion, even in difficult to access areas such as corners, bores and fillets.
