Saving the drawing function, the DRO allows to save the drawings into the system which makes the machining to be much more convenient. Special previewing the drawing function, after setting well the parameters, the DRO will display the machined well effect which makes the operating be more visual. Displaying the tool’s current position function, during the machining, the system will display the tool’s current position according to the drawing which makes the machining be much more easier. Help function, during the machining, if there is any doubt, pressing the help button will help you to solve.

When the DRO is under Inch mode, the decimals are optional for 4 or 5, user can set according to their using habit. This kind of DRO is commonly fitted to machines, especially for metal working lathes, cylindrical grinders, milling machines, surface grinders, boring mills and other machine tools to allow the operator to work faster and with greater accuracy.
