Numerical control machine tool double-shaft synchronization controller

The invention discloses a digit control machine double-shaft synchronization control device, comprising a clock, an input and output interface, a double-shaft position check module, a control unit, asystem parameter list and a pitch compensation list, wherein the double-shaft position check module processes position and synchronization error check for two synchronous shaft motor encoders and provides the check information to the control unit, the control unit selects a working mode corresponding to the parameters of the system parameter list, according to the position and error information ofthe two synchronous shafts provided with the double-shaft position check module and the process corresponding to the selected working mode, the control on the two synchronous shafts can be realized.The invention resolves the problem of the common digit control system which can not realize synchronous control, realizes the real-time character between transfer and adjustment, avoids the profile error of processed elements c
