Heidenhain’s Acu-Rite brand has released a line of three digital readouts (DROs) with software features and hardware for milling, turning, grinding and boring applications.The models support software features that include an Installation Guide that appears at first-time power up, as well as Dynamic Zoom that, once activated, enlarges the display values for the axis being moved at a given point. This enables the user to immediately see which axis is currently in motion.

The DRO100 unit has been designed as a functional yet simple DRO that can be easily understood by the operator. The DRO203 offers all the basic functions, plus common features for both milling and turning applications such as bolt-hole calculations for milling and vectoring/taper ratio for turning. The DRO300 high-end programmable model is available in three- and four-axis variants. It is the only unit in the series offering the connector for external switching functions. It includes the option of expanding the system to serve as a six-axis DRO.

Other new software features common to all three models include improved file management, whereby users can save or load firmware, configuration files, graphic files and instruction manuals. Additionally, a simpler user management system has been introduced, and as many as nine users can operate the DRO203 and DRO300 units.
