Abstract: The invention discloses a multi-head rolling surface polishing cutter, and belongs to the technical field of machining cutters. The multi-head rolling surface polishing cutter comprises a cutter rest and five cutter bits, wherein the cutter bits are rolling bits, and mainly consist of balls, support frames, wear resistant plates, lower pressing plates, compression springs, upper pressing plates, pressing screws and the like. The cutter rest can be connected with a machine tool spindle through a Morse taper handle and the like; the balls are put into the support frames, and are pressed with the wear resistant plates having circular grooves; the wear resistant plates are pressed with the lower pressing plates and the upper pressing plates; and the compression springs are mounted between the upper and lower pressing plates. The multi-head rolling surface polishing cutter has the following advantages: through the cutter bit mechanical rolling effect, the material surface smoothness and levelness are improved, the surface pressure stress is improved, the material surface grain size is reduced, and the material surface performance is enhanced; and through the cutter multi-head design, the cutter machining efficiency and using performance are improved.
