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.
