precision edm drilling machine for sale

This 3-axis CNC EDM deep-hole drilling machine is a high-precision, high-efficiency system specifically designed for machining micro-holes and deep holes in conductive materials. It utilizes a copper tube electrode in conjunction with high-frequency pulsed discharge to electro-erode the workpiece, while employing high-pressure deionized water for chip evacuation and cooling. This equipment excels at processing hard, heat-resistant, and geometrically complex materialssuch as

The machine follows the principle of pulse spark erosion machining. It uses tubular copper or brass electrodes as the cutting tool, with high-frequency pulse voltage generated between the electrode and the grounded conductive workpiece. Continuous tiny electric sparks are produced in the insulating dielectric fluid, and the instantaneous high temperature generated by spark discharge melts and vaporizes the local metal material to achieve non-contact material removal and hole
