    摘要： A surface cutting method for a hot-rolled steel product that includes a joint portion having a predetermined breaking strength includes a step of clamping the steel product between a pair of milling cutters that are arranged on top and bottom surfaces of the steel product, while the steel product is conveyed in a longitudinal running direction. The top and bottom surfaces of the steel product are subjected to cutting by rotating the milling cutters in a rotating direction. A cutting resistance applied to the milling cutters during the cutting is determined based on parameters including type of steel, width, thickness, surface temperature and conveying speed of the steel product, as well as circumferential speed and cutting depth of the milling cutters. The cutting resistance is controlled by adjusting the cutting depth of the milling cutters by actuators connected to the milling cutters, such that a tension lower than the breaking strength of the joint portion is applied to the steel product by the cutting resistance, so as to prevent breakage of the joint portion during the cutting.

    摘要： The equal-pitch groove processing device (1) comprises transferring means (10), (40) for continuously transferring a workpiece (100) in an axial direction of the workpiece (100); processing tools (23), (33) in which cutting teeth (23a) of a thickness corresponding to a width of a groove to be processed are formed around an outer peripheral portion along a spiral path, and which is rotatively driven with the center of that spiral as an axis; and controlling means (70), (80) for synchronously operating the processing tools (23), (33) in such a manner that the workpiece (100) is transferred by a one-normal-pitch portion of the spiral while the processing tools (23), (33) undergo one revolution, whereby equal-pitch grooves are formed in the workpiece (100) by the cutting teeth (23a) of the processing tools (23), (33).

    摘要： A shaping machine wherein either a work or a tool is a rod-like member extending along a straight center line while the other is a member having a hole capable of being fitted on the rod-like member and wherein the work is shaped while the member having the hole passes through the rod-like member from one end toward the other end of the rod-like member. The shaping machine comprises a feed mechanism for causing relative movement of the rod-like member and the member having the hole to each other along the center line of the rod-like member, a center line of the feed mechanism being coincident with the center line of the rod-like member.
