A method for complex-decommissioning a nuclear facility is disclosed. The method for complex-decommissioning the nuclear facility includes: cutting and expanding an inner wall of the cavity; installing a cutting device that cuts and decommissions the nuclear reactor pressure vessel inside the cavity; fixing the nuclear reactor pressure vessel inside the cavity by using a fixture; and cutting and decommissioning the nuclear reactor pressure vessel fixed inside the cavity by using a cutting device.

Sawing tool forms a surface structure on a road surface, has a shaft and number of diamond saw blades, each diamond saw blade has disc-shaped core with hole for placing on shaft. A segment is on outer circumference of core, and saw blades are arranged on shaft by disc-shaped core. Segments of adjacent diamond saw blades are in surface contact on longitudinal side, each segment formed from two layers adjoining one another in axial direction and extending in radial and axial direction. Axially adjoining layers of segment each have different wear resistances and wear resistance of layers in axial direction alternates over axially entire segment, so a furrow is formed by two layers adjoining one another, in order to set a grip and a noise level of the road surface. Axially adjoining layers of adjacent segments have different wear resistances forming an alternating layer structure over entire sawing tool.

A method for producing a tire rasp blade for mounting on a rasp hub is described. The tire rasp blade has a blade body and blade teeth. A main part of the tire rasp blade is austenitized by heating the main part to an austenitization temperature. The tire rasp blade is then tempered. The austenitizing process is performed by induction heating the tire rasp blade until the austenitization temperature is reached. The austenitizing process is followed by a quenching process, wherein the quenching is started before austenitization temperature is reached, whereby the quenching process briefly overlaps the induction heating. A tire rasp blade is also described.

A cylindrical cutting tool for processing splines formed on an outer circumference of a shaft member to extend in an axial direction includes blade portions which are formed in a spline shape on an inner circumference. The blade portions include: a first blade portion which is formed in a terminal end portion in a first direction along the axial direction and which is directed substantially toward the first direction; and a second blade portion which is formed in a terminal end portion in a second direction along the axial direction and opposite to the first direction and which is directed substantially toward the second direction.
