Machined Components

Precision machined components are fundamental in applications from aircraft engines to MEMS devices. The machined surfaces of these components may serve a variety of functions, including sealing, oil retention, cosmetic appearance, etc. The surfaces of  optical grade mirrors and actuating structures of MEMS (Micro-Electro-Mechanical Systems) devices also fall into this category. In all cases, understanding the surface texture of the functional surfaces is critical for proper performance. 

Many methods are available for measuring surface texture on precision components. The methods tend to divide into two categories: low-resolution yet easy-to-use systems, and higher end 3D measurement systems with higher resolution but more limitations on the components that can be measured. Inspectors are often faced with a trade-off between ease of measurement versus higher-resolution, repeatable measurements.

In many cases, the higher resolution systems are simply not an option. Large components, or components with flanges, small radii, blind holes and other difficult to access features also prove challenging to measure with sufficient resolution.

The 4D InSpec Surface Gauge measures surface defects, as well as fine features such as rivet depth and dot peening, right on the factory floor. Fast, portable and easy to learn, the 4D InSpec is the world’s first handheld, high resolution surface defect measurement system.
