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.

  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.

CNC Control SYSTEM

Control Function

  1. X, Y, Z axis is CNC, the electrical control accuracy is 0.001mm,
  2. X, Y, Z axis has absolute zero
  3. Automatic edge-finding and center finding function
  4. With deep positioning function , the electrode lifting height can be set, Automatic remind of short-circuit etc.
  5. The parameters can be set using the keypad on the computer screen, like pulse parameters, process current, servo and other processing parameters.
  6. X, Y, Z driven by AC servo motor
  7. With manual operation 
  8. NC-axis power-down memory function
  9. NC-axis has the function of backlash compensation
  10. NC-axis with manual clear zero functions (setting relative to zero)
  11. Adapt to carrying knives, cut into large pulse function
  12. With a classification carrying knives feature

Processing Programming Function

  1. Processing location and processing path using G code programming, it can achieve X, Y, Z axis CNC operation. Any two-axis can up to Translational function of NC and return the original trajectory.
  2. We can set the parameters in processing parameters  page with the keyboard. Such as the depth of processing, pulse width, pulse width, pulse gap, processing the current, carrying the knife height. Computer control the machine tools based on these settings automatically converted Criteria processing.
