Nibihe bikoreshwa mubice byihuta byihuta byo guhuza imipira?

Inganda zifatika zifata inganda zumva ko imikorere yihuta yihuta ya ibikoresho bya mashini yo gukata ibyuma bya CNC biterwa no kuzunguruka no gusiga amavuta ku rugero runini.Imashini zikoresha imashini zitwara igihugu cyanjye ziratera imbere byihuse, zitanga ubwoko butandukanye kuva buto kugeza bunini, ubwiza bwibicuruzwa na tekiniki kuva hasi kugeza hejuru, igipimo cyinganda kuva kuri gito kugeza kinini, hamwe na sisitemu yumwuga wabigize umwuga ufite ibyiciro byibicuruzwa byuzuye kandi umusaruro ushimishije. Imiterere.Kwihanganira ibintu bya spindle ni bike.Birakwiriye cyane cyane kubyitwaramo bisaba kuyobora neza cyane hamwe nubushobozi bwihuta.Birakwiriye cyane cyane kubitondekanya byimashini yimashini.Kubera ubukana bwayo bwiza, busobanutse neza, ubushobozi bwo gutwara imizigo hamwe nuburyo bworoshye ugereranije, ibyuma bizunguruka ntibikoreshwa gusa muri spindle yibikoresho rusange byo gukata, ahubwo binashimangirwa nibikoresho byihuta byihuta.Urebye umuvuduko mwinshi, imipira yo guhuza imipira ifatanye mu kuzunguruka, ibyuma bya silindrique ni ibya kabiri, kandi ibyuma bifata imashini ni bibi cyane.

Umupira (ni ukuvuga umupira) wumupira woguhuza umupira utambitse kandi urazunguruka, kandi utanga imbaraga za centrifugal Fc na gyro torque Mg.Hamwe no kwiyongera k'umuvuduko wa spindle, imbaraga za centrifugal Fc na gyro torque Mg nazo ziziyongera cyane, ibyo bizatera ubwikorezi kubyara imihangayiko minini yo guhura, bizatuma ubwiyongere bukabije bwikwirakwizwa, kwiyongera kwubushyuhe, kugabanuka kwukuri n'ubuzima bugufi.Kubwibyo, kugirango tunoze imikorere yihuta yiyi mikorere, hagomba gukorwa ibishoboka byose kugirango ubwiyongere bwa Fc na Mg.Duhereye ku mibare yo kubara imipira ihuza umupira Fc na Mg, birazwi ko kugabanya ubucucike bwibikoresho byumupira, diameter yumupira hamwe nu mpande zumupira bifasha kugabanya Fc na Mg, ubu rero hejuru- umuvuduko ukabije ukoresha impande zingana na 15 ° cyangwa 20 ° Zumupira muto wa diameter.Ariko, diameter yumupira ntishobora kugabanuka cyane.Ahanini, irashobora kuba 70% gusa yumurongo wumupira wumurongo wa diametre, kugirango idaca intege ubukana bwikintu.Icy'ingenzi ni ugushaka kunoza ibikoresho byumupira.

Ugereranije na GCr15 ifite ibyuma, ubucucike bwa nitride ya silicon (Si3N4) ni 41% gusa yubucucike bwayo.Umupira wakozwe na nitride ya silicon iroroshye cyane.Mubisanzwe, imbaraga za centrifugal na gyro torque zabyaye mugihe cyihuta cyihuta nazo ni nto.benshi.Muri icyo gihe, modulus ya elastique hamwe nubukomezi bwa silicon nitride ceramics yikubye inshuro 1.5 ninshuro 2,3 zo gutwara ibyuma, naho coefficent yo kwagura ubushyuhe ni 25% gusa byuma byuma, bishobora kuzamura ubukana nubuzima bwikwirakwizwa, ariko kandi Ihuza ryibintu byerekana impinduka nke mubihe bitandukanye byo kuzamuka kwubushyuhe, kandi akazi ni iyo kwizerwa.Byongeye kandi, ceramic irwanya ubushyuhe bwinshi kandi ntabwo ifatanye nicyuma.Biragaragara, umuzenguruko wakozwe na silicon nitride ceramic irakwiriye cyane kuzunguruka byihuse.Imyitozo yerekanye ko umupira wamaguru ceramic uhuza imipira ihuza imipira irashobora kongera umuvuduko wa 25% ~ 35% ugereranije nu byuma bihuye nu byuma, ariko igiciro kiri hejuru.

Mu bihugu by'amahanga, ibyuma bifite impeta y'imbere n'inyuma hamwe n'ibikoresho bya ceramic bizunguruka hamwe byitwa Hybrid.Kugeza ubu, ibyuma bivangavanze bifite iterambere rishya: kimwe ni uko ibikoresho bya ceramique byakoreshejwe mu gukora ibizunguruka bya silindrike, hamwe na ceramic silindrical Hybride yagaragaye ku isoko;ikindi ni ugukoresha ibyuma bitagira umwanda aho kwitwaza ibyuma kugirango ukore impeta y'imbere ninyuma yimbere, cyane cyane impeta y'imbere.Kubera ko coefficente yo kwagura ubushyuhe bwibyuma bitagira umuyonga ari 20% ugereranije n’ibyuma bitwara ibyuma, mubisanzwe, kwiyongera kwingutu ziterwa no guterwa no kwagura ubushyuhe bwimpeta yimbere bizahagarikwa mugihe cyo kuzunguruka byihuse.
