Sažetak
Honanje ili vlačno glačanje je postupak kojim obrađujemo najfinije površine metala radi postizanja zahtijevane točnosti i kvalitete obrađenih površina. Samo honanje kao i procesi struganja, glodanja, brušenja, tj. rezno uobličavanje metalnih materijala u svom se djelovanju ograničava na relativno tanak površinski sloj izratka i uglavnom izaziva hladnu plastičnu deformaciju, ali ne utječe dalekosežno na strukturu i svojstva materijala.
Pri izvođenju procesa honanja vrlo je bitno da se radna površina oplahuje znatnim količinama sredstava za hlađenje i podmazivanje. Radnu površinu valja hladiti da ne bi došlo do promjene strukture zbog procesa rekristalizacije i otpuštanja. Osim toga, ispiranjem se odvodi metalna prašina nastala honanjem te iščupana zrnca s bruseva. Danas su istraživanja na ovom području usmjerena na primjenu novih sredstava za hlađenje i podmazivanje.
Na temelju ekonomske i ekološke analize i analize kvalitete postupka honanja pri primjeni sredstava za hlađenje i podmazivanje na osnovi mineralnih ulja i uz sadržaj različitih tipova aditiva, u radu je ispitivana mogućnost primjene novih ulja pri honanju košuljica cilindara.Abstract
Honing is a procedure treating the finest metal surfaces in order to achieve the required precision and quality of treated surfaces. Honing itself, as well as proceses of grating, milling, grinding, i.e. using cutting for the shaping of metal materials, is in its activity limited to a relatively thin surface layer of the workpiece, mostly causing cold plastic deformation, without any long-term impacts on either the structure or properties of the material.
When performing the process of honing, it is extremely important that the working surface be washed by considerable volumes of the cooling and lubrication agents. The working surface needs to be cooled, so as not to cause any structural change due to the processes of recrystallization and release. Apart from that, rinsing takes away the metal dust generated by honing, as well as the pulled out grinding wheel grains. Research in this area is today oriented towards applying new cooling and lubricating agents.
Based on economic and environmental analysis, as well as that of the quality of honing procedure when applying cooling and lubricating agents based on mineral oils, containing various types of additives, the paper also considers the possibility of applying new oils for the honing of cylinder bores
