Here are the characteristics of an EDM (Electrical Discharge Machining) hole drilling machine translated into English:
Wide Range of Materials: Suitable for processing stainless steel, hardened steel, hard alloys, copper, aluminum, and other conductive materials, without being limited by material hardness.
Hole Diameter Range: Generally between φ0.3mm and φ3mm, with a high aspect ratio of up to 200:1 or even 300:1.
Processing Speed: Can reach 20-60 mm per minute.
Technological Advantages: Uses pulse discharge technology with high energy density, minimizing heat transfer and reducing thermal effects on the material.
Non-Contact Processing: The electrode does not come into direct contact with the workpiece during processing, reducing mechanical stress and making it suitable for complex shapes and small holes.
Flexible Electrode Material Selection: Tool electrode materials can be steel, cast iron, copper, etc.
High Precision: Capable of producing very small holes with high inner surface finish.
High Automation Level: Features automatic electrode dressing, adjustable processing voltage, and other functionalities.
