Heidenhain Corp.’s Acu-Rite brand introduces new software for its 300 Series digital readout (DRO) that now allows users to control a sinker EDM machine. This new development broadens this established DRO’s use to include most common manual shop machines such as milling, turning, grinding, and EDM in a single DRO.

When Acu-Rite’s EDM software is loaded into a DRO300 and coupled with an IOB 610 interface box, it enables simple control of sinker EDM using three relay signals. This software is now included on all new multipurpose DRO300s. For those who already own an Acu-Rite DRO300, v1.3.1 can be downloaded for free on the Software Updates page.

ACU-RITE DRO300 features for EDM control:

  • Automatic depth programming - EDM's ram can be configured to automatically retract or dwell at the target depth
  • Dwell cycle – Relay holds Z depth until spark-out occurs or can control an orbiter cycle
  • Reverse fault detection - Prevents creep out of bath during burn cycle
  • EDM display mode - Shows current ram depth, maximum depth reached, target depth, simultaneously on the three-axis displays
