To provide an untraditional and epoch-making polishing device comprising abrasive cloth paper, a rotating polishing body and moving device part to carry out deburring work and uniform polishing of other portions.

This polishing device is constituted so that a large number of the polishing bodies 7 each of which is constituted by polymerizing and arranging a pair of the abrasive cloth paper 4 one side of which is formed in an abrasive grain surface 5 and the other side of which is formed in a non-abrasive grain surface 5a are provided in a radial state against an auto-rotating rotation axis (a) and in a state provided side by side through a prescribed interval in the axial direction of the auto-rotating rotation axis (a), a surface of each of the polishing bodies 7 is provided in an opposed state of the axial direction of the auto-rotating rotation axis (a), a large number of the polishing bodies 7 provided on this auto-rotating rotation axis (a) are rotated by rotating them around this auto-rotating rotation axis (a) as their axes, and a rotating polishing body 1 constituted to polish a work material 6 such as a metal material, wood, etc. and a moving device part M to make this rotating polishing body 1 contact with the work material 6 while moving this rotating polishing body 1 in a direction where a speed component in the axial direction of the auto-rotating rotation axis (a) is generated are provided.
