edm hole drilling machine for sale high speed

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, ...

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 ...
