For manual lathe and milling machine applications, CE-certified Model DP900 DRO has graphical LCD-based display that can be specified with 2, 3, or 4 axes. Graphical dynamic tool position allows operator to observe tool movement on DRO in real-time. Integrated geometric calculations let operators establish datum points or take inspection readings when part is still on machine. Geometric reading can be captured with or without use of optional touch probe.
