Electro Discharge Machine EDM
The electro discharge machine type SEC 400 spark eroder is an upgrade 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 new camera movement permit the fine focus control.
The machine renew completely the drilling working process based on a new feed-back circuit. Consequently this guarantees a fast and easy drilling of the gasket, producing decisive advantages in the high pressure research experiments with Diamonds Anvil Cell.
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
