4D InSpec Applications


Aerospace

Aircraft Jet Engine

The 4D InSpec was designed with field maintenance applications in mind. Use the gauge 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 fir-tree roots, even blind features and holes, all with micrometer 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.

Eliminate Replication

To measure defects on large or complex components inspectors are faced with limited measurement options. 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 an inspector must make a silicone replica or rubber replica of the surface—a time-consuming, 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 a silicone replica would prove difficult to make.

Measure Corrosion

Left unchecked corrosion can impede performance and can lead to component failure, sometimes with catastrophic results. Inspectors must be able to accurately determine corrosion severity 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 measure pit depth, width and volume, of all corrosion pits within the field of view. Quickly inspect corrosion over large portions of a component for a thorough, accurate assessment of the severity, even in difficult to access areas such as corners, bores and fillets.
