This possibility to increase the process performance is often not allowed when decommissioning nuclear facilities in order to avoid crosscontamination. The grinding segments attached to the wire are not able to use the self-sharpening effect, when machining metal. The machined metal does not have sufficient abrasive effect on the tools metallic bond to effectively reset it in the case of multilayer grinding segments and to expose further grain layers. Consequently, only single-layer grinding segments are used for wire sawing of metals [1, 2]. In contrast to multilayer grinding segments, only one layer of abrasive grains is present in the bond. If this layer is worn out, the complete wire sawing tool must be replaced which in turn causes high running costs. The goal of this work is to qualify multilayered abrasive segments for the cutting of pure metal structures and thereby increase the productivity of the dismantling process. With an adapted sharpening process, however, this problem can be solved by specifically resetting the bond of the wire sawing tools and engage new diamond grain layers. One possibility to compensate the missing self-sharpening effect when cutting metal is contact erosive sharpening. Due to the metallic bond of the wire sawing tools available on the market, this process is suitable for resetting the bonds of the grinding segments. The Diamonds are not damaged by the process due to their low electric conductivity [3, 4]. Another critical issue is the adaptation of the abrasive segments bond with regard to the highest possible retention forces and contact erosion dressability. Brazed abrasive segments have considerably higher grain retention forces than sintered abrasive segments. However, the brazed segments are only available on the market with one grain layer of diamonds, ast hese grinding segments are not designed for a dressing process or self-sharpening. For this reason, multilayer brazed grinding segments were produced for the first time and examined in terms of their contact erosive Dressing properties.

Internationales Symposium "Konditionierung radioaktiver Betriebs- und Stilllegungsabfälle" einschließlich 14. Statusbericht des BMBF "Stilllegung und Rückbau kerntechnischer Anlagen", KONTEC 2019, 27.-29. März 2019, Dresden, 6 Seiten. | Datei | Beschreibung: 454 nuclear power plants with an average age of 31 years were in operation worldwide in January 2019, according to the International Atomic Energy Agency (IAEA). These nuclear facilities must be decommissioned in an orderly manner after the end of their operational use. Thus, the decommissioning industry will face a large number of costly decommissioning projects in the near future [1, 2]. The dismantling of a nuclear facility imposes high requirements for production engineering. Many different, complex steel and reinforced concrete structures are used in the facilities, which are difficult to access due to contamination and complex design of the reactor. Since the 1990s, in addition to conventional mechanical cutting processes such as sawing processes and thermal cutting processes, wire grinding has also been increasingly used [3]. Wire grind-ing is characterised by high flexibility in terms of workpiece geometry and achievable depth of cut, as well as low space requirements which is favourable for decommissioning components that are difficult to access. In order to avoid the contamination of coolants when dismantling nuclear facilities, the focus is on the further development of the compressed air-cooled wire grinding process. The resulting contaminated dusts can be controlled more easily and extracted directly from the process [4]. Conventional wire grinding tools used for cutting steel consist of segments made of diamond grains within a sin-tered or brazed bond strung on a steel wire. The productivity of these tools for machining steel structures is limited by the low thermal stability of diamond combined with its chemical affinity to iron. Furthermore, the use of a single layer bond is limiting the lifetime of the wire grinding tool. Thus, the aim of this paper is to qualify a new type of wire grinding segment meeting the requirements for efficient dry cutting of steel components. This includes the substitu-tion of the diamond grains with polycrystalline cubic boron nitride (CBN) due to its high thermal stability and a multi-layer bond to increase the lifetime of the tool.
