The EDM machine type SEC 400 spark eroder is designed with new concepts and solutions with decisive advantages. Is used in DAC’s cell utility for a fast and easy drilling of the gasket with different materials. The bottom camera is one of the main features to avoid misaglignment.
The process is obtained using electrical discharges (sparks). Material is removed from the workpiece (gasket) by a series of rapidly recurring current discharges between two electrodes (tip and gasket) separated by a dielectric liquid and subject to an electric voltage. https://www.youtube.com/watch?v=xBHcKSFdSUc
