design of PLC controlled hydraulic servo system to achieve CNC Milling-landing spindle box dynamic control. In this hydraulic system, the application of electro-hydraulic servo valves and servo control system to control the pressure and the piston rod displacement, realize right by tilting spindle box and error compensation. This will not only improve the machining precision, but also improve the force Column
