Pulsed electrochemical machining (PECM) is changing how complex components can be manufactured, yet most engineered parts are still designed around the limitations of conventional machining methods such as CNC. Constraints like tool access, line-of-sight machining, and material-dependent cutting behavior often force engineers to simplify internal features, reduce feature density, or compromise critical geometries. In practice, this means many parts are designed for manufactur

Primary manufacturing methods such as CNC and laser drilling have had a storied history of stability and reliability in machining near-net-shape components from tough materials into unique geometries. But it's the secondary post-processing operations where these methods quietly lose both time and control. Voxel's pulsed electrochemical machining (PECM) offers postprocessing capabilities for metal components that are scalable, reliable and precise.
