Abstract

Glavni vzrok za preveliko obrabo, slabo kakovost površin izvrtin ter predčasen lom orodja pri konvencionalnem vrtanju predstavlja neučinkovito hlajenje in mazanje rezalne cone. Tako zaključno delo obravnava metodo visokotlačnega dovajanja hladilno mazalne emulzije skozi orodje in ga glede na obrabo orodja ter velikost odrezkov primerja s konvencionalnim nizkotlačnim dovodom. Ugotovili smo, da je za uporabljeno orodje (Sumitomo Electric) razlika med obrabama pri konvencionalnem in visokotlačnem dovajanju skozi orodje zanemarljivo majhna. Po drugi strani pa smo ugotovili, da se močno izboljša tvorba in lomljivost odrezkov pri visokotlačnem vrtanju, kar vodi do večje stabilnosti in produktivnosti procesa.

Secondary title: Through-tool high pressure coolant drilling
Secondary abstract: The main cause of excessive wear, poor surface finish of drill holes and premature tool breakage with conventional drilling is inefficient cooling and lubrication of the cutting zone. This paper represents through % tool high pressure coolant application in drilling and compares it with conventional low pressure cooling using tool wear and chip length. The results illustrated that the difference between tool wear of conventional and tool wear of high pressure cooling was negligibly small. The results also showed that chip breakage was more efficient under HPC method and since there was no formation of continuous chips, stability and productivity of the drilling process were improved.
