EDM Sinker Features

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.

Control System

ZNC System Technical Performance

  1. There is an automatic A.R.C (carbon deposit sensitivity device) to prevent damaging workpiece
  2. VLSI, high power VMOS to provide power.
  3. High and low clearance individual circuit.
  4. PWM (impulse width) servo system, standard DC servo motor.
  5. Synchronous discharge system of high voltage superposited.
  6. Square wave and equal energy output.
  7. Circuits of super-fine process.
  8. Capacity of voltage regulation is ±20%.
  9. Circuits of copper electrode and graphite electrode are separate and individual process parameters.
  10. Discharge parameters can be edited automatically, and there are rough, medium, fine, superfine process terms to be chosen.
  11. Z axis is of super-precision process, process position can be affirmed repeatedly.
  12. There are some safe devices in circuit. 
    • Self-diagnostic system and LED state display, convenient to examine and repair
      Oil level control, process device will be stopped automatically
      If temperature of working fluid is too high according to induction, the process will be cut off automatically
      Temperature induction, fire extinguisher sprays automatically and cut off the power supply at the same time
      Light sensitive device, self-response, and fire extinguisher cut off the power supply at the same time
      Automatic fire extinguisher, which is featured in best security, without pollution, there is no damaged to machine and mould.
