摘要： A first laser working method includes a step of irradiating the metallic work held by a rotation holding mechanism, with a nanosecond laser beam from a first laser oscillation mechanism, to form a through hole, and a step of irradiating, when the metallic work is rotated under the action of the rotation holding mechanism, the inner wall of the through hole with a picosecond laser beam from a second laser oscillation mechanism, thereby to finish the same. While forming the through hole, metal vapor is sucked from the outside of the metallic work. Then, the gas is fed from the outside of the metallic work, and the inside of the metallic work is suctioned. In a second laser working method, when a lower hole made through is radially enlarged, the exit side of the lower hole is kept lower in pressure than the laser incident (or entrance) side.

摘要： A method of laser machining a small hole with high machining precision in a machined object. The method includes the steps of emitting a laser beam with a fixed optical axis onto a machined object while the machined object is rotated. When the optical axis of the laser beam is fixed in place, the edges of the small hole to be machined are irradiated and the small hole becomes essentially circular even if the cross-sectional shape at the focus of the laser beam is not circular. When the small hole is formed completely through the machined object, a plume is suctioned for removal from a portion of the machined object on a side opposite from the machined hole.

摘要： A laminated ring for use as a belt in transmitting power in a continuously variable transmission is produced by welding opposite ends of a sheet of maraging steel to produce a plurality of rings, and rolling said rings to a predetermined length. The rings are nitrided in a salt-bath nitriding process by dipping the rings in a molten salt containing 38-46% of CNO− and 1-2% of CN− and heated to a temperature in the range from 480 to 530° C., for a period of time ranging from 10 to 25 minutes. The nitrided rings are finally stacked into a laminated ring.

摘要： A cylindrical drum is prepared by welding opposite ends of a thin sheet of maraging steel. A first solution treatment is effected on the cylindrical drum, and then the cylindrical drum is severed into a plurality of rings each having a predetermined width. After the rings are rolled, a second solution treatment is effected on the rings which have been rolled, and then the circumferential length of each of the rings is corrected. The rings are aged and nitrided, and then stacked into a laminated ring. The first solution treatment and the second solution treatment are effected using the same heating furnace in the same atmosphere in the same temperature range.

摘要： A rotatable workpiece holder for holding a hollow cylindrical workpiece thereon functions as a chiller for cooling the hollow cylindrical workpiece. A coolant, e.g., water, is supplied to the hollow cylindrical workpiece through second coolant passages and branch passageways defined in the workpiece holder, thereby cooling the hollow cylindrical workpiece. The coolant forms a film in a clearance between the outer surface of an annular side wall of the workpiece holder and the inner circumferential surface of the hollow cylindrical workpiece.
