1.Processing principle
Using electrode tubes (brass tubes, purple copper tubes) as processing electrodes, utilizing the principle of electric
discharge erosion, a high-frequency pulse power supply is applied between the electrode (hollow copper tube) and
the workpiece to form a small pulse width and high peak current discharge machining, supplemented by a
high-pressure water pump for cooling and slag removal, greatly accelerating the erosion speed of the workpiece.
2.Applicable scope
2.1. Suitable for machining deep small holes with diameters ranging from 0.15mm-3mm on various conductive
materials such as stainless steel, quenched steel, copper, aluminum, and hard alloys. It can directly penetrate and
process irregular shaped surfaces such as slopes and surfaces.
2.2. It is mainly used for the processing of small holes on the mold, as well as the threading holes, the spinneret
holes of the chemical fiber spinneret and spinneret, the group holes of the filter plate and sieve plate, the cooling
holes of the discharge motor blade and the cylinder body, the oil and gas path holes of the hydraulic pneumatic valve
body, etc; It can also be used to remove drill bits and taps that are broken in the workpiece without damaging the
original hole or thread.
2.3. Use purified water or tap water as the processing coolant
