Features

3 axis CNC EDM drilling machine DD703 series adopts the electrode tube (yellow steel tube, plain steel tube) as the tool electrode using EDM etching principle, between the electrode (hollow steel tube) and the work of applying high-frequency pulsed power supply to form a small pulse width, the large peak current of the discharge processing, supplemented by a steam-operated high-pressure pump cooling and slag discharge.

Make the etching speed of the workpiece is greatly accelerated, especially suitable for stainless steel, hardened steel, aluminum, hard aluminum alloy and other conductive materials on the processing diameter of 0.15mm-3.0mm between the deep small holes, the depth of the diameter ratio can reach 300:1 or more, can be directly in the workpiece of the sloping, curved surfaces into the processing.

Applications

3 axis CNC EDM piercing machine DD703 series is mainly used for the processing of thousands of holes on the molds and threading holes, chemical fiber spinnerets, spinneret holes of the spinneret boards, filter boards, filter boards, filter boards, the group of holes of the division boards, the engine blades, the heat dissipation holes of the cylinder block, the hydraulic, the oil circuit of the automobile parade, the steam circuit holes, etc., and also used for the etching of the drills and the silk vias that are folded off in the workpieces, etc..
