Cutter disc interchangeability machining device

The utility model relates to the technical field of cutterhead machining, in particular to a cutterhead interchangeability machining device, a to-be-machined part of a cutterhead at least comprises a first machining part located on the end face and a second machining part located on the side face, the machining device comprises a numerical control rotary table, and the numerical control rotary table is connected with a two-shaft rotating mechanism. The first rotating axis of the two-axis rotating mechanism coincides with the center line of the cutter head, the second rotating axis of the numerical control rotary table is perpendicular to the first rotating axis, and a tool assembly used for clamping and positioning the cutter head is installed on the numerical control rotary table. According to the cutterhead interchangeability machining device, original secondary positioning dispersed machining of workpieces is changed into primary positioning clamping of parts, all machining of key parts is completed, secon
