The invention relates to equipment for machining an inner hole of a pipeline, in particular to equipment for replacing a welding groove in the inner wall of a pipeline for an electric heater of a nuclear power voltage stabilizer. The invention aims to provide the numerical control equipment for machining the inner wall groove, which can be used for automatically machining a small-diameter pipeline in a nuclear environment and simplifying the operation steps. According to the technical scheme, the device comprises a feeding device, a rotating device, a clamping device, a remote monitoring system and a control system, a feeding servo motor of the feeding device drives a ball screw to rotate, and the ball screw is connected with a ball screw nut on a feeding table; a rotary servo motor of the rotary device drives a rotary gear to rotate, and a milling cutter is mounted on the rotary gear; a pneumatic motor of the clamping device drives a clamping gear to rotate, a spiral groove of the clamping gear makes contact
