DRO is a multi-function digital readout which is used for different machines (milling machine, boring machine, lathe machine, grinding machine) by setting the parameters. It has a lot of graphics processing capabilities. For example:? Special function only for milling machine (R arc function, parts round function, slope processing function, slash drilling function, progressive cavity processing)? Special function only for lathe machine (tool library function, taper measurement function and so on). With the help(aid) of these functions, it can greatly reduce the difficulty of processing graphics. Features:? Displaying as 8 digits with green LED. Unique film makes covering on the Windows makes the displaying much more recognizable. Basic Specificaton:? Voltage:AC80-260V/50HZ-60HZ? Power dissipation:20VA? Coordinate number:2/3?
