Summary

The Makino EDNC20 is a CNC sinker-type electrical discharge machine designed for machining complex cavities and features in electrically conductive materials using controlled spark erosion. It delivers high-precision results with large workpiece capacity and rapid high-speed Z-axis jump motions, aimed at reducing cycle times in mold and die making or similar applications. Notable characteristics include a space-saving stationary table, advanced Hyper-i control system with user-friendly interface, and options for automatic tool changing and extended axis strokes.
