The invention discloses a numerical control two-sided lathe for machining large-diameter thin-wall disc parts. The numerical control two-sided lathe comprises a main drive system, two feeding system sets, a lathe body and a servo motor. The main drive system is provided with a main shaft which is of a hollow structure and used for mounting a clamp and connected with the servo motor. The clamp is used for clamping parts to be machined and comprises a clamp body and a pressing plate. The two feeding system sets are symmetrically arranged on the two sides of the main shaft. Each feeding system set comprises an x-direction movement assembly, a z-direction movement assembly and a knife rest. The x-direction movement assembly is arranged on the lathe body in the radial direction of the main shaft. The z-direction movement assembly is arranged on the x-direction movement assembly in the axial direction of the main shaft. The knife rest is arranged on the z-direction movement assembly. The knife rest can move in the x direction and the z direction through the x-direction movement assembly and the z-direction movement assembly. By means of the numerical control two-sided lathe, two-sided synchronous turning of the disc parts can be achieved, normal cutting force born by the parts counteract one another in the machining process, machining deformation of thin-wall parts can be reduced effectively, and machining accuracy is high.
