ABSTRACT:
A bore processing device for processing an inner surface of a bore of an object to be processed, includes: a taper member having a taper section; a roller arranged to contact and rotate around an outer surface of the taper member; a roller guide member having a guide groove for accommodating the roller and arranged to rotate around the outer surface of the taper member; a first motor for moving the roller guide member to insert the roller into the bore of the object; a second motor for rotating one of the object and the roller guide member; and a third motor for axially moving one of the roller guide member and the taper member so that one of the roller guide member and the taper member relatively moves to the other thereof. The device further includes a detecting device for detecting an axial load applied to the object by the roller when the roller is inserted into the bore of the object.
