PROBLEM TO BE SOLVED: To provide an abrasive grain fluidizing type working device capable of obtaining stable polishing accuracy without changing polishing condition even though the shape and size of a workpiece and a jig are changed and the viscosity and kind of a media are changed. SOLUTION: In the case of executing abrasive grain fluidizing type working such as burring, corner rounding and surface polishing by fixing a workpiece 5 between upper and lower cylinders 1, 2 movably built into the cavity of the jig 3, filling the media 4 with which an abrasive is mixed into a high molecular material having characteristics provided with both viscosity and elasticity, and applying pressure to the media 4 by the upper and lower cylinders 1, 2 so that the inner and outer surfaces of the workpiece 5 are moved under pressure, a speed of the upper and lower cylinders 1, 2 pushing the media 4 is constantly controlled by a cylinder control part 6.
