CBN Yinjiza na Carbide Yinjiza: Inzira-Igiciro-Imikorere yo Gukora Ibikoresho Bikomeye

CBN Yinjiza na Carbide Yinjiza: Inzira-Igiciro-Imikorere yo Gukora Ibikoresho Bikomeye

Mu nganda zigezweho, gutunganya ibintu bigoye biragenda bigaragara cyane cyane mu nganda nk’imodoka, icyogajuru, hamwe n’ibikoresho, aho ubukana bwibikorwa bikunze kurenga HRC50. Mu bihe nk'ibi, guhitamo ibikoresho bigira ingaruka ku buryo butaziguye ku musaruro, ubuziranenge bwo gutunganya, n'ibiciro muri rusange. Muburyo buboneka,CBN (Cubic Boron Nitride) yinjizanakarbideni ibisubizo bibiri by'ingenzi.

Iyi ngingo igereranya ibiri murwego enye zingenzi -gukomera, kurwanya ubushyuhe, ubuzima bwibikoresho, nigiciro-Gusobanura neza imipaka ikoreshwa ya CBN yinjiza. Irerekana kandi ikiguzi-cyigiciro cyimyigire yimashini ikora.

I. Kugereranya imikorere

1. Gukomera

• Kwinjiza CBN: Icya kabiri gusa kuri diyama mubukomere, nibyiza mugukora ibyuma bikomye hejuru ya HRC50, ifu ya metallurgie, hamwe nubushyuhe bwo hejuru.

• Kwinjiza Carbide: Gukomera hafi ya HRA90. Kwambara ibikoresho byihuta cyane mugihe utunganya ibikoresho hejuru ya HRC45.

2. Kurwanya Ubushyuhe

• Kwinjiza CBN: Ihangane n'ubushyuhe bugera kuri 1200 ° C, bukwiranye no gukata byihuse, kugabanya imikoreshereze ikonje.

• Kwinjiza Carbide: Kurwanya ubushyuhe bugera kuri ~ 800 ° C; bikunda guhindagurika kwa plastike no kwambara kumpande kumuvuduko mwinshi.

3. Igikoresho cyubuzima

• Kwinjiza CBN: Irashobora kumara inshuro 5-10 kurenza karbide mugihe utunganya ibikoresho bikomeye, bitanga umutekano muke.

• Kwinjiza Carbide: Igikoresho ubuzima kigabanuka cyane kubikoresho bikomeye, bisaba gusimburwa kenshi no gutera igihe.

4. Igiciro

• Kwinjiza CBN: Igiciro cyo hejuru hejuru kuri insert, ariko ikiguzi kuri buri gice kigabanuka kubera kuramba.

• Kwinjiza Carbide: Hasi igiciro cyambere, ariko gusimburwa kenshi bizamura igiciro rusange.

II. Gusaba Imipaka ya CBN Kwinjiza

Ukurikije ibi bipimo, ibintu byiza byinjizwamo CBN birashobora kuvugwa muri make nka:

• Gukomera kw'ibikoresho: HRC50 no hejuru, nk'ibyuma bikomeye, ifu ya metallurgie, hamwe n'ubushyuhe bwo hejuru.

• Ingano yicyiciro: Hagati kugeza mubunini, aho ibikoresho byubuzima inyungu igabanya igiciro.

• Ibisabwa neza: Kwihanganira ibipimo IT6 cyangwa byiza, uburinganire bwubutaka Ra ≤ 0.8 μ m.

• Uburyo bwo gukora: Kwihuta kwihuta gukata, kurangiza, cyangwa kurangiza.

Iyo ubukana bwibintu buri hasi (munsi ya HRC45), ingano yicyiciro ni nto, cyangwa ibisabwa byuzuye biringaniye, gushyiramo karbide bikomeza guhitamo amafaranga menshi.

III. Ibikoresho byimodoka Kwiga

Gufata nyuma yubushyuhe-bwo kuvura kurangiza ibikoresho byohereza imodoka nkurugero:

• Ibikoresho: 20CrMnTi, ikomye kuri HRC58–62.

• Ibisabwa: Ibipimo bifatika IT6, uburinganire bwubutaka Ra0.8.

Igisubizo:Mugihe gikomeye-kinini, icyiciro-kinini, cyogukora neza-ibikoresho, nubwo gushyiramo CBN bihenze cyane kuri buri gice, ubuzima bwabo burambye, guhindura ibikoresho bike, hamwe nubushobozi buhanitse bugabanya ibiciro kuri buri gice mugihe byemeza ubuziranenge hamwe nibiciro biri hasi.

IV. Umwanzuro hamwe nuburyo bwo guhitamo ibikoresho

Kubikorwa biri hejuru ya HRC50, hamwe nibisobanuro bihanitse hamwe nibisabwa-binini,Kwinjiza CBN bitanga igiciro cyiza-cyimikorere, kugabanya cyane ibiciro byinganda no kuzamura imikorere. Kubukomere buke cyangwa imirimo-mato mato,gushyiramo karbide bikomeza kuba ingirakamaro kandi byubukungu.

Uburyo bworoshye bwo guhitamo ibikoresho:

Niba (Gukomera kw'ibikoresho ≥ HRC50) KANDI (Ingano yubunini ≥ Hagati) KANDI (Icyitonderwa ≥ IT6)HitamoShyiramo CBN
UbundiHitamoShyiramo Carbide

Ibigo birashobora gukoresha iyi formula nkibisubizo byihuse, mugihe hanarebwa ubushobozi bwibikoresho, kugabanya umuvuduko, nuburyo bukonje. Gushiraho uburyo bwuzuye bwo gusesengura inyungu-yo guhitamo ibikoresho bizamura umusaruro no guhangana.
