Machining equipment for outer surface of workpiece

The invention provides machining equipment for the outer surface of a workpiece, and belongs to the technical field of machining. The machining equipment solves the problem that the production efficiency is low. The machining equipment comprises a top plate, a first rotating disc, a second rotating disc, a first matching plate and a second matching plate, wherein the first rotating disc, the second rotating disc, the first matching plate and the second matching plate are arranged on the top plate. A first disc is arranged on the first rotating disc, and a first forming channel which can conduct gear hobbing or character hobbing on the workpiece when the first rotating disc rotates is formed between the end of the first matching plate and the peripheral face of the first disc. A second disc is arranged on the second rotating disc, and a second forming channel which can conduct gear hobbing or character hobbing on the workpiece when the second rotating disc rotates is formed between the end of the second matchi
