[0031] The front side of the column 16 is equipped with a cylinder as a support movement driving mechanism 13 and a guide rail 14 and a slider 15 as a support movement supporting mechanism.

One end of the emery belt 9 is wound on one of the emery belt winding drums 12, and the other end is wound on the other emery belt winding drum 12, forming a belt path from one emery belt winding drum around the bottom side of the pressing head to the other emery belt winding drum.

[0034] The bearing roller rotates with the center line as the axis driven by the support friction of the two supporting shafts. The abrasive belt is supported by the oscillating mechanism so that the super-finished working surface of the abrasive belt is in soft contact with the outer cylindrical surface of the bearing roller, and reciprocates along the generatrix direction of the bearing roller to achieve full axial coverage of the outer cylindrical surface of the bearing roller. The abrasive belt is rotated and wound by the winding drum and slowly moves in a direction perpendicular to the generatrix of the bearing roller to achieve the transposition of the super-finished working surface of the abrasive belt.

[0037] The contact body can also be a roller movably mounted on the pressing head, so that the friction between the emery belt and the contact body is reduced when the emery belt moves and changes position.

[0038] As another implementation of the pressing head, a contact body is provided on the pressing head 101. The contact body is a soft body that can be concave by being squeezed so that the emery cloth belt and the roller can form an arc wrapping.
