DEA ALPHA - Flexible, affordable and accurate gantry CMM


The DEA ALPHA is an all-purpose flexible CMM for the dimensional inspection of large castings and machined parts. ALPHA is available in two versions: ALPHA Classic and ALPHA Performance. Equipped with high-productivity 3D scanning laser head and continuous servo wrist options, it can rapidly acquire millions data points from complex contoured shapes, and is the ideal system for die and mold manufacturing process. All ALPHA versions can be supplied with optional bellows and covers which offer machine protection for airborne shop contaminants.

For over 40 years DEA has been the unrivaled market leader in gantry coordinate measuring machines. Superior technology, innovative solutions and constant development in collaboration with customers have led to over 1,400 installations worldwide. The gantry architecture is the ideal solution for all measurement applications for large-sized automotive and aerospace components, as well as heavy transportation, communication and satellite equipment. Easy loading and integration with part transportation systems, ease of access to the measuring volume, and world class dynamic and accuracy performance are only some of the most prized capabilities of the DEA gantry line.

ALPHA Classic is a multi-purpose flexible CMM for dimensional inspection of large casting and machined parts. When equipped with optical scanning sensors, the system can rapidly digitize millions of data points on free-form components. It is therefore an ideal reverse-engineering and inspection system for the die and mould manufacturing process.

ALPHA Performance is a high performance gantry CMM which incorporates several unique design features and state-of-the-art components such as a high-resolution dual scale system on the Y axis and a high rigidity silicon carbide spindle. A linear temperature compensation makes ALPHA Performance an extreme performer, easy to use under all operating conditions.
