Abstract
A rolling flat cutter having finishing blades corresponding to corrugation of a product to be obtained by working a tubular or cylindrical workpiece, and a method of rolling by the flat cutter. When the workpiece is worked, a pair of flat cutters are disposed such that the finishing blades face each other, and the cutters are moved rectilinearly in opposite directions perpendicular to a direction in which the finishing blades extend so that the corrugation is formed on a periphery of the workpiece from an end to the other in an axial direction thereof. As to the rolling flat cutter, a flat cutter is used which comprises a rectangular cutter body, a triangular blade base formed as a higher step on one side of a plane of the cutter body along a straight line parallel with a diagonal of the plane, and the finishing blades are formed on the blade base.
