Claim 0:
1. An abrasive water jet full-section cutting type cutter head, comprising a cutter head body and a rotor eccentrically arranged on a working surface of the cutter head body,
wherein the cutter head body is rotatable; the rotor revolves with the cutter head body about an axis of the rotation of the cutter head body and also rotates on an axis of the rotor; at least one first nozzle is arranged close to an edge of a working surface of the rotor; at least two groups of second nozzles, wherein each group comprises at least one second nozzle, and at least one third nozzle are arranged on the working surface of the cutter head body, during the rotation of the cutter head body and the rotor, abrasive water jet flows of the second nozzles of the at least two groups and the at least one third nozzle cooperate to form a combined abrasive water jet flow producing cutting trajectories that cover a region to be processed in front of the cutter head body, then a material to be cut in front of the cutter head body is cut into a plurality of concentric rings during motion, and an abrasive water jet flow of the at least one first nozzle cuts the plurality of concentric rings into fragments with the motion of the cutter head body and the rotor.
