The utility model relates to a digital control lathe for machining an engine crankshaft connecting rod. The digital control lathe comprises a lathe base, a four-shaft linkage system controller, a first servo motor, a front portion rotating machine body, a turntable, turning lathe surface guide rails, a turning lathe surface guide sleeve, a first lead screw, a lead screw fixing part, tool rest guide rails, a tool fixing seat, second servo motors, a tool handle, turning tools, a second lead screw, a transmission shaft, a rear portion following machine body and a turning lathe surface. Rotation of the servo motor is controlled through the four-shaft linkage system controller, accordingly the turning lathe surface is indirectly driven to move in a left-and-right mode, the axial machining size of the crankshaft connecting rod is achieved, rotation of the front servo motor and the rear servo motor is controlled, accordingly the front turning tool and the rear turning tool are indirectly driven to be fed forwardly and reversely, and the radial machining size of the crankshaft connecting rod is achieved. The digital control lathe uses a digital control operating system to replace an original hydraulic system, is simple and convenient to operate and high in working efficiency, improves the consistency of machining size and reduces device fault maintenance rate and machining cost.
