Igikoresho cyo gukata CBNsni ubwoko bwibikoresho byo gukata superhard, bikozwe hifashishijwe ubushyuhe burenze urugero hamwe nubuhanga bwumuvuduko mwinshi ukoresheje ifu ya CBN nkibikoresho fatizo na bike bya binder.Bitewe nuburemere bukabije bwibikoresho byo gukata CBN, birakwiriye cyane gutunganya ibikoresho bifite ubukana burenze HRC50 kandi birwanya kwambara.
Nibihe bikoresho CBN？
CBN (cubic boron nitride) nigikoresho cyibikoresho bya superhard byakozwe nyuma ya diyama yubukorikori, ihindurwa na nitride ya boron ya hexagonal (grafite yera) munsi yubushyuhe bwinshi nigitutu.CBN ni boride idafite ibyuma, kandi ubukana bwayo ni iya kabiri nyuma ya diyama, iruta kure cyane ibyuma byihuta kandi byoroshye.Kubwibyo, nyuma yo gukorwa mubikoresho, CBN irakwiriye cyane gutunganya ibikoresho bihagaze hamwe nibikoresho byo guca karbide.
Ni ibihe bikoreshoGukata CBN ibikoreshobikwiriye gutunganywa?
Ibikoresho byo gukata CBN birashobora gukoreshwa mugukata ibikoresho nkibyuma bikomye (bitwaje ibyuma, ibyuma byabugenewe, nibindi), ibyuma bikozwe mucyuma (icyuma cyumuhondo, icyuma cyangiza, icyuma kinini cya chromium, icyuma gishobora kwihanganira ibyuma, nibindi), ibyuma byihuse, ibyuma bikomeye, ubushyuhe bwo hejuru cyane, nibindi, kandi bifite ibyiza byinshi mugutunganya ibyuma bya ferrous.
Twabibutsa ko niba ibikoresho byo gutunganya ari ibyuma byoroshye cyangwa bitari ibyuma, ibikoresho byo guca CBN ntibikwiriye gutunganywa.Ibikoresho byo gukata CBN birasabwa gusa mugihe ubukana bwibintu bugeze kurwego runaka (HRC> 50).
BisanzweKwinjiza CBN imiterere
Muri rusange, ibikoresho bikoreshwa mugukata muguhindura imashini cyane cyane bifite imiterere yuburyo bukurikira: kwinjiza CBN hamwe no gusudira kwa CBN, muri byo harimo gusudira CBN harimo gushiramo insimburangingo hamwe no gushiramo gusudira.
(1) Kwinjiza CBN.Icyuma cyose cyacuzwe muri poro ya CBN, hamwe no gukata impande nyinshi.Byombi hejuru no hepfo inama zicyuma zirashobora gukoreshwa mugukata, bikavamo gukoresha cyane icyuma cyambaye ubusa.Kandi icyuma gifite imbaraga zo kugonda cyane kandi kirashobora kwihanganira gukata byihuse hamwe nubujyakuzimu bunini, bikwiranye no gukomeza, intege nkeya, hamwe no gukata rimwe na rimwe ibidukikije.Ifite uburyo bwagutse kandi irashobora kuzuza ibisabwa byo gutondeka neza, igice cyuzuye, no gutunganya neza.
(2) Kwinjiza muri rusange CBN.Ifishi yo gusudira yumubiri yose ifite imbaraga zo gusudira hamwe nu mwobo wo hagati uhagaze, ushobora gusimbuza icyinjiriro.Bikwiranye nuburyo bwo gutunganya ibintu hamwe nubujyakuzimu bwa <2mm, intege nke zigihe gito kandi zikomeza gutunganya ibidukikije, byujuje ibyifuzo bya kimwe cya kabiri cyuzuye kandi gikwiye.
(3) Kwinjiza gusudira CBN gushiramo.Nyuma yo gukata, uduce duto twa CBN dusobekeranye dusobekeranye kumurongo ukomeye kugirango ube uhinduranya kandi urambiranye.Mubisanzwe, impande imwe gusa irahari, cyane cyane ikoreshwa muburyo bwo gutunganya neza.
Kugeza ubu, ibikoresho byo guca CBN bikoreshwa cyane haba mu gihugu ndetse no ku rwego mpuzamahanga, cyane cyane mu guca ibikoresho bigoye ku mashini mu nganda nko gukora amamodoka (moteri, crankshafts, disiki ya feri, ingoma za feri, nibindi), inganda zikora ubucukuzi bw'amabuye y'agaciro (kuzunguruka inkuta za minisiteri, pompe zidatemba, nibindi), gutwara inganda (hub hub, ibyuma byogosha, ibyuma byumuyaga, ibyuma, nibindi), hamwe ninganda zikora (ibyuma byuma, ibyuma byihuta cyane, nibindi).
