The utility model discloses a high-wearing resistant inner wall processing device. The processing device is characterized by comprising a high temperature heating clamp (1) and an extrusion tool (3) with arc, wherein a workpiece (2) pre-drilled with a hole smaller than a forming aperture is clamped in the high temperature heating clamp (1) and is heated to 4/5 of a melting point in the processing procedure, the outer diameter of the extrusion tool (3) with the arc for extruding the workpiece is greater than the aperture of a final forming hole. The processing device is used for heating the inner wall drilled with a hole with a certain diameter, and then performing one time of extrusion through the extrusion tool to obtain a required inner hole; not only is the method simple, but also the wearing resistance degree of the inner wall is greatly improved, and the wearing resistance is improved by 20% in comparison with the conventional method of drilling and cutting the inner wall.
