DPM is capable of detecting digital signale signals of sparking density, providing feedback to the CNC system and calculating the sparking size.
It controls the sparking energy, wire tension force and water pressure more precisely; increases cutting speed and accuracy when cutting on irregular thickness workpieces.

CBefore the machining, on-line measurement and calibration instead of the conventional one, significantly reduce the time to calibrate the workpiece. With the macro command the automatic measurement calibrates the reference point; enhance the machining accuracy. After machining, directly on-line measure the workpiece on the table; avoid the unexpected error from dismount/mount the workpiece.

Multi-workpiece machining

  • Automatic compensating the 3D flatness of workpiece.
  • Automatic compensating the parallelism of workpiece (AR)
  • Automatic machining reference point measurement.
  • Processing AWT automatic wire threading
  • Go to the next workpiece to continue processing.
