DownloadPECM Technology for "Soft" Turbine-Blade Machining
EMAG's PECM technology is used on the PO 100 SF.
This technology is a targeted refinement of the ECM process, where the gap between the workpiece and the tool through which the electrolyte solution flows is especially narrow. Simultaneously, the feed is superimposed by a mechanical oscillation movement. The two factors together ensure an even more effective, precise removal of the material – which generates financial benefits as well. Expensive milling tools are no longer required, and thermal influences do not impact the turbine blades. This and perfect surfaces with low roughness values produced by the PECM process ensure that post-processing is practically eliminated.
