EDMMax SD750 Super Driller

The SD Drillers are all built on top of a precision granite table for stability and accuracy. These EDM drillers are Gantry-style so that the workpiece remains fixed, and the electrode moves in the X, Y and Z. This allows for very heavy workpieces. The X, Y and Z drives are Panasonic AC servo motors with rotary encoder feedback. The CNC Controller is a standard PC in Windows, and the Power Supply is 60 amps to allow for drilling up to 6.0mm. A larger 100-amp power supply is available. CE safety is standard.

Auto Electrode Changer is standard from 11-32 positions depending on the model.

Auto Guide Changer is also standard equipment.

Optional B-axis and AB-axis indexers are available as are robot interfaces for automation.

  • Electrode lengths are 400, 600 and 700mm
  • Electrode stabilizers are included as standard.
