A processing device and a processing method for a foam polishing pad, and a foam polishing pad obtained therefrom, the processing device comprises a gear type cutter, and the polishing pad can be processed by multiple rows of gear cutters, thereby improving the working efficiency of the foam polishing pad groove processing ; The polishing pad processing method using the processing device not only solves the problem that the plunge milling tool cannot perform complete cutting.

　　In addition, the gear-type cutter is matched with gas cooling, which can greatly reduce the temperature of the foam polishing pad and the cutter during processing, and avoid the melting phenomenon of the vertical milling cutter.

　　Foam polishing pad conditioner and method of making the same

　　The foam polishing pad conditioner includes: a metal base; a plurality of connection mechanisms, each connection mechanism at least includes a groove structure, the groove structure is opened on the upper surface of the metal base for holding adhesive; dressing; The device body is fastened and bonded on the upper surface of the metal base through the plurality of connecting mechanisms.

　　The foam polishing pad dresser has high strength. By carving a plurality of groove structures with specific shapes on the sticking surface of the metal base, and dropping a certain amount of adhesive in the groove structure, the dresser body is attached Cover the metal base and press gently to make the trimmer body fit with the metal base with a high degree of flatness.
