These NC universal dividing heads have respectively the center height as 110, 125, 140, 145, 150mm and are main accessories for the NC machines and CNC machining centers. It can also be used as one of the main accessories of semi-automatic millers, borers or other machine tools. Connected with the CNC control device or the control system of the machine and the 4~6 Bar pressure air, the NC dividing head can carry out the performance of clamping, unclamping and circularly indexing at arbitrary angles for the workpiece. This series NC dividing heads can be mounted vertically and horizontally on the working-tables of the NC machine tools.
