SUMMARY Maintenance of classic machine tools At a time when the presence of CNC machines is commonplace, various solutions are offered on the market, from cheap and questionable quality machines from the East to more advanced and technically refined machines of today, from school machines of mod- est dimensions to gantry-multi-spindle monstrosities; we ask ourselves why a classic ma- chine tool? The classic machine tool offers a very easy adaptation to various tasks that are imposed daily. That's why we often meet them in tool shops and maintenance, prototype produc- tion, workshops with a wide assortment, etc. There are many applications where CNC machines are either too expensive or not flexible enough. This approach, along with ex- perience and engineering knowledge of the subject, offers a new pair of gloves for solving problems and finding solutions (software, computer...). Before various uses, it is very important to carry out regular maintenance of the machine, as well as to take care of it in special applications when the machine is exposed to in- creased wear or possible damage. For these last-mentioned reasons, we take care of its maintenance to use the full potential of the machine in its entirety (stiffness, accuracy, linearity, repeatability, etc.). The subject of this work is a general inspection of the Prvomajska TNP 160B lathe, the execution of the necessary machine maintenance procedures, pointing out irregularities and proper handling during their removal and repair. Proper maintenance is crucial in the proper and productive operation of any machine, which is what this paper will address. In addition to all the above, the technology of production, replacement and assembly of cer- tain parts will also be discussed.
