Large Scale Sinker EDM Machines

Now available from ONA are one and two head large scale sinker modular EDM machines. The modular machines allow the user to design a custom machine at the cost of a standard machine. In all cases, users can choose the X, Y and Z travels of their choice. For the QX10/TQX10 sinker EDMs, 40 different configurations are available.

Manifold configurations of XYZ travels:

  • X travel: 1,500, 2,000 or 3,000 mm / 59.0", 78.7" or 118.1"
  • Y travel: 750, 1,000 or 1,500 mm / 29.5", 39. 4" or 59.0"
  • Z travel: 650, 800 or 1,000 mm / 25.6", 31.5" or 39.4".

Independent CNC generators command the one or two heads. The volumetric compensation function in the CNC is designed to provide high levels of long-term precision. The two head model allows the possibility of eroding two cavities simultaneously and independently in a large workpiece.

The machine is a rigid mechanical structure of stabilized fine-grained cast iron blended with graphite. It is a fixed bedframe machine that allows workpieces up to 25,000 kg. (55,000 lbs.)

Standard on the series are: super fine finishing power supply (finishes to VDI=0), long life filtering system (min. 10,000 working hours), fully automated filtering unit, erosion expert system and a remote control.

ONA also offers wire large scale modular EDM machines. Between the wire and sinker models there is a choice of 60 different configurations.
