In order to meet the requirements of the comprehensive test experiment of the domestic highspeed roll grinding head, a hydraulic control system of integrated oil supply platform for the highspeed roll grinding head was designed by analyzing the existing technology of the domestic CNC roll grinding machine, especially for the lubrication characteristics of all kinds of the oil film lubrication bearings and different parts of highspeed grinding head. The PLC control system was developed, including the design of hardware PLC control circuit and the development of software. The debugging results show that the electrohydraulic control system of integrated oil supply platform for highspeed roll grinding head not only has a high degree of automation,but also has stable operation under the circumstances of different fuel pressure and rotating speed, which provides a strong experimental condition for the localization of highspeed roll grinding machine.
