20.500.12556/RUL-144614 Generalna obnova univerzalne stružnice Potisje PA30-B Restoration of universal lathe Potisje PA30-B V diplomski nalogi je predstavljen in opisan postopek struženja ter delovanje univerzalnih stružnic z njihovi ključni sestavni deli. Podrobno je predstavljena geometrija konvencionalnih strojev, opisan postopek strganja površin in doseganje kvalitete naležnih površin ter postopki niveliranja in centriranja univerzalne stružnice. Predstavljen je celoten postopek generalne obnove univerzalne stružnice z opisanimi postopki obnove mehanskih delov, brušenja vodil, izdelavo novega elektro-krmilnega dela in opisana celotna ličarska obnova ter končna montaža vseh sestavnih delov. Na zaključku naloge so izvedene meritve, ki predstavijo kvaliteto dosežene geometrije in izvedene meritve pri struženju obdelovancev, ki so pokazale izredno natančnost in ponovljivost znotraj 0,01 mm pri delovanju ter obdelavi. Predstavljene so tudi iztočnice za nadaljnje delo ter ukrepi za nadgradnjo in izboljšavo delovanja univerzalne stružnice. The thesis presents and describes the turning process and the operation of universal lathes with their key components. The geometry of conventional machines is presented in detail, the process of scraping surfaces and achieving surface quality is described, as well as the levelling and centring procedures of a universal lathe. The complete general renovation of the universal lathe is presented, describing the overhaul of mechanical parts, the grinding of the guides, the construction of a new electrical and control part, complete representation of paint job and final assembly of all components. At the end of the thesis, measurements are made to demonstrate the quality of the geometry achieved and the measurements made in turning the workpieces, which showed a remarkable accuracy and repeatability within 0. 01 mm in operation and machining. It also presents suggestions for future work and steps to upgrade and improve the performance of the universal lathe. generalna obnova univerzalna stružnica geometrija stroja strganje centriranje niveliranje general renovation universal metal lathe geometry of machine hand scraping central alignment machine leveling true false false [J.
