Specifically, the three groove structure units 2 are 170mm long and 36mm wide, the cross sections of the three groove structure units are respectively rectangular 2-1, trapezoidal 2-2 and inclined edge 2-3 which are parabolic trapezoid-like, the depth of the rectangular groove is 13mm, the width of the rectangular groove is 36mm, the length of the rectangular groove is 170mm, and two groups of four through holes with the diameter of 6.5mm are formed in the bottom surface of the groove; the distance from the section of the groove structure unit 2 to the upper bottom is 8mm, and the distance from the section of the groove structure unit to the lower bottom is 13 mm; the bottom of the groove structure unit 2 is provided with two groups of 4 screw holes m6 corresponding to the roller body 1.
Parabolic trough units and wedge-shaped trough units are intermittently arranged in 12 rectangular troughs of the roller main body shown in figures 1 and 2, so that the polishing roller with both hydraulic pressure and uniformity is obtained. When the roller rotates along with the main shaft, polishing liquid flows in from the large opening side and flows out from the small opening side of the groove unit, so that a layer of dynamic pressure liquid film is generated in a workpiece mounting gap, abrasive particles in the liquid film obtain enough energy under the action of fluid shearing force and dynamic pressure, and then impact protruding micro-sources on the surface of the workpiece at a certain angle to achieve atomic-level removal of materials.
