Abstract:V podjetju SŽ – Vleka in tehnika, d. o. o., Center Ljubljana, se ukvarjajo z vzdrževanjem vseh vrst železniških vozil, vleko vlakov in tehničnimi vagonskimi dejavnostmi. Vzdrževalna dela, opravljena na voznih površinah kolesnih dvojic različnih vrst železniških vozil, se izvajajo z uporabo podnivojske kopirne stružnice proizvajalca Hegenscheidt-MFD, tipa stroja 105 z letom izdelave 1979. Modernizacija obdelovalnega stroja bi izboljšala konkurenčnost z drugimi tujimi vzdrževalnimi podjetji na trgu. V magistrskem delu so za boljše razumevanje predstavljene tematike najprej opredeljene osnove na področju obdelave in vzdrževanja tekalnih profilov in sledilnih vencev kolesnih dvojic na tirnih vozilih. Nato je v prvem sklopu zaključnega dela analizirana podnivojska kopirna stružnica, uporabljena v obravnavanem podjetju. To vključuje opis sestavnih komponent, določitev tehničnih specifikacij stroja, predstavitev načina delovanja stroja, opredelitev poglavitnih pomanjkljivosti stroja ter navedbo vzrokov za neuspelo posodobitev in lastnosti izvedljive modernizacije obdelovalnega stroja. V drugem sklopu zaključnega dela je za obravnavano podjetje po izpolnitvi različnih pomembnih kriterijev in z najboljšimi tehničnimi specifikacijami izbran vodilni model podnivojske CNC-stružnice na trgu. V zaključku so primerjane tehnične specifikacije in način delovanja uporabljene podnivojske kopirne stružnice z izvedeno možno posodobitvijo in predlaganim novim modelom podnivojske CNC-stružnice. Na osnovi vseh pridobljenih podatkov je obravnavanemu podjetju predlagan najboljši potek ukrepanja na področju strategije konkurenčnosti vzdrževanja tirnih vozil.

Title:Modernization of the underfloor copying wheel lathe for reprofiling of railroad wheelsets
Abstract:In the company SŽ - Vleka in tehnika d.o.o., Center Ljubljana, they deal with an array of railway services ranging from train traction and maintenance of the rolling stock to technical wagon activity. The maintenance work performed on the running surfaces of the wheel sets of various types of railway vehicles is carried out using an underfloor copying wheel lathe of the manufacturer Hegenscheidt-MFD, machine type 105, made in 1979. The desire to modernize the processing machine would improve competitiveness with other foreign maintenance companies present on the market. For a better understanding of the represented topics, the basics in the field of processing and maintenance of profiles and flanges of the wheel sets on rail vehicles are first described in the master's thesis. And then, in the first part of the master's thesis, the company's underfloor copying wheel lathe is analyzed. It includes a description of the components, a determination of the technical specifications, the way the machine works, a definition of the main shortcomings, causes of the desired failed modernization and the characteristics of feasible modernization of the machine tool. In the second part of the final work, after fulfilling various important criteria and with the best technical specifications, the leading model of the underfloor wheel CNC lathe currently present on the market was selected for the company SŽ - Vleka in tehnika d.o.o., Center Ljubljana. In conclusion, the technical specifications and operation procedure are compared of the used underfloor copying wheel lathe with a possible modernization and a proposed new model of underfloor wheel CNC lathe. On the basis of all the obtained data, the best course of action is proposed to the company SŽ - Vleka in tehnika d.o.o., Center Ljubljana in the field of the strategy of competitiveness of rolling stock maintenance.
