EDM CNC Machine
- Can directly penetrate and machine from oblique surfaces, curved surfaces, and other irregular shapes.
- Can erode and remove broken drill bits and taps in workpieces without damaging the original holes or threads.
- Uses pure water or tap water as machining coolant.
- Spindle lifting and secondary lifting both adopt Taiwan linear guides and ball screws, ensuring excellent machining accuracy.
- Spindle lifting uses subdivided stepper motor drive, achieving fast lifting with electric control of head travel.
- Motor rotary head adopts tungsten steel wear-resistant pieces and multi-layer waterproof structure, ensuring chuck rotation concentricity.
- Z-axis maximum stroke 400mm, can clamp 500mm long electrodes at one time, with low electrode tube waste.
- Worktable X, Y axes equipped with grating digital display, resolution 0.005mm.
- Maximum machining depth-to-diameter ratio is 300:1.
- Maximum drilling speed is 30-60mm/rpm.
- Digital high frequency replaces traditional analog high frequency for better accuracy; PWM dedicated pulse output, eliminating DIP switches for better stability; high frequency soft start function, burr-free machined surfaces.
Available Functions
Depth Setting Function
Uses encoding disc counting with A and B phase orthogonal decoding, strong anti-interference capability, more accurate depth setting.
One-Key Machining Function
Drilling requires only one key press.
Smart Retract Function
Set workpiece thickness, when workpiece is penetrated, one-key machining ends, automatically retracts to workpiece surface.
Limit Function
When hitting lower limit, automatically rises to top; if needing to change copper tube mid-process, just press copper tube change function, also rises directly to top.
Product Features — Machining Principle
Adopts electrode tubes (brass tubes, copper tubes) as machining electrodes, utilizing EDM discharge erosion principle; applies high-frequency pulse power supply between the electrode (hollow copper tube) and workpiece to form small pulse width and high peak current discharge machining, assisted by high-pressure water pump for cooling and slag removal, greatly accelerating workpiece material removal speed.
Application Scope
Material Applicability
Suitable for machining deep small holes with diameters between 0.3mm-3mm on various conductive materials including stainless steel, hardened steel, copper, aluminum, and cemented carbide.
Main Applications
Mainly used for machining small micro holes on molds as well as wire threading holes, chemical fiber spinneret holes and spinneret plate holes, group holes in filter plates and screen plates, heat dissipation holes in EDM machine blades and cylinder bodies, oil and gas holes in hydraulic and pneumatic valve bodies; also can be used to erode and remove broken drill bits and taps in workpieces.
