CBN yankan kayan aikiskasance daga cikin nau'ikan kayan aikin yankan da suka fi ƙarfin gaske, waɗanda ake kera su ta amfani da matsanancin zafin jiki da fasahar matsa lamba ta amfani da foda na CBN azaman ɗanyen abu da ɗan ƙaramin ɗaure.Saboda tsananin taurin kayan aikin yankan na CBN, ya dace sosai don sarrafa kayan aiki tare da taurin sama da HRC50 da juriya mai ƙarfi.
Wani abu ne CBN?
CBN (cubic boron nitride) kayan aiki ne mai wuyar gaske wanda aka haɓaka bayan lu'u-lu'u na wucin gadi, wanda aka canza daga boron nitride hexagonal (fararen graphite) ƙarƙashin matsanancin zafin jiki da matsa lamba.CBN boride ne wanda ba karfe ba, kuma taurinsa ya wuce lu’u-lu’u, wanda ya fi karfin karfe mai saurin gaske da gauraye.Saboda haka, bayan an yi shi da kayan aiki, CBN ya fi dacewa don sarrafa kayan da ke tsaye tare da kayan aikin yankan carbide.
Menene kayanBabban bankin CBN kayan aikidace da sarrafawa?
Ana iya amfani da kayan aikin yankan CBN don yanke abubuwa kamar taurin ƙarfe (ƙarfe mai ɗaukar ƙarfe, ƙarfe mai ƙura, da sauransu), ƙarfe (ƙarfe mai launin toka, baƙin ƙarfe, ƙarfe mai girman chromium simintin ƙarfe, ƙarfe na ƙarfe mai jurewa da sauransu). karfe mai saurin gudu, gami da karfi, gami da zafin jiki mai zafi, da sauransu, kuma suna da fa'ida sosai wajen sarrafa karfen karfe.
Ya kamata a lura cewa idan kayan sarrafa ƙarfe ne mai laushi ko ba ƙarfe ba, kayan aikin yankan CBN ba su dace da sarrafawa ba.Ana ba da shawarar kayan aikin yankan CBN ne kawai lokacin da taurin kayan ya kai wani matakin (HRC>50).
