To provide an apparatus for processing surface for repairing a cavity by repeatedly pressurizing a circumference of the cavity in an inner circumferential surface of a casting having a cylinder part.
The apparatus for processing surface is provided with a surface processing tool 9. The surface processing tool 9 has rolling rollers 10 having central axes of rolling N, and uneven parts 12 in which pressurizing projections 121 having pressurizing surfaces 12f for pressurizing an inner circumferential surface Cs of a casting C and groves 120, are alternatively arranged in a circumferential direction centering on the central axes of rolling N. The uneven parts 12 have shapes for pressurizing at least a part of: positions to be pressurized which are pressurized with any one of the pressurizing surfaces 12f formed in the inner circumferential surface Cs with the rolling rollers 10 being rolled on the inner circumferential surface Cs; and positions not to be pressurized in the positions not to be pressurized inserted into the positions to be pressurized; with any one of the pressurizing surfaces 12f with the rolling rollers 10 being sent to a direction of the axes of rolling N.
