Main Application

EDM sinker machine is used for cavity forming. It utilizes conductive material (copper, graphite, steel) as electrode to process workpiece (conductive material) by spark erosion. Main use: processing precious die, cavity mold and so on. It is widely used in metal processing and mold making workshop.

Our company's EDM series machines are featured in strong functions, convenient and reliable operation, of fairly good rigidity, running placidly, of good controllability, suitable to process conductive metal moulds, complicated metal parts and templates with high precision, high toughness and difficult processing. EDM process has become the important part in the field of mechanical manufacture. They are widely used in the fields of moulds, electronic instruments, precision mechanical process, automobile parts, military, etc.



  1. Adopt Japan SANYO FC servo motor.
  2. Steady safety device, optical sensors, auto answer, fire extinguisher and power cut off.
  3. Good machine structure , high rigidity ,high precision , adopt V slide design.
  4. Adopt HT300 ageing treatment casting ,keep precision long time.
  5. Adopt high quality imported oil pump.
  6. Three-axis linear scale;
  7. Can choose red oil, pumping oil slagging mode, but also choose not to dip the oil processing;
  8. For copper, graphite, steel, on the cavity, and special shape holes machining
  9.  Lubrication system uses recovery mode, rail lubrication action at once, and keep the look clean
  10.  Moistureproof, Antirust, rust, gold plated K PCB board design
