Enabling Aerospace Innovations with PECM
Pulsed electrochemical machining (PECM) is applied in aerospace where tight geometric control, burr-free features, and repeatability across production volumes are required in materials that are difficult to machine conventionally. Voxel applies PECM to aerospace components with complex internal and external features, supporting consistent feature replication while avoiding tool-induced damage or residual stress. PECM particularly well suited for applications where edge condition, internal surface quality, and part-to-part consistency directly impact performance and reliability.

Blades & Vanes
Voxel applies PECM to aerospace blades and vanes where edge condition, feature consistency, and repeatability across parts directly affect aerodynamic performance and reliability. PECM enables burr-free machining and finishing of thin sections, edge features, and repeated geometries without introducing tool-induced damage or residual stress. Through the use of custom-designed cathodes, Voxel supports consistent feature replication across production volumes, making PECM well suited for blade and vane components where geometric variation or post-processing risk must be tightly controlled.

Micro Heat Exchangers
Voxel applies PECM to aerospace heat exchanger components incorporating dense microchannel geometries in high-temperature alloys such as Inconel. PECM enables the formation and internal finishing of narrow channels and thin-wall features while avoiding mechanical forces that can distort geometry or initiate cracks. By leveraging custom cathode designs and controlled pulsed electrochemistry, Voxel delivers repeatable microchannel features and internal surface quality across parts, supporting heat exchanger designs where thermal performance, flow uniformity, and production consistency are critical.

"EHAR" Cooling Channels
Voxel applies PECM to aerospace components requiring extreme-high-aspect-ratio (EHAR) cooling channels up to 300:1, where conventional drilling or EDM approaches face limitations in consistency, burr control, or internal surface quality. PECM enables the machining of deep, narrow cooling features with controlled geometry and smooth internal surfaces, reducing the risk of flow restriction or defect initiation. Using application-specific cathodes, Voxel achieves feature-to-feature and part-to-part repeatability for EHAR cooling channels in materials where precision and reliability are essential to component performance.
