Okwangoku, iiparamitha zesakhiwo sangaphakathi seebheringi zebhola ezitywiniweyo zegroove kwilizwe lam ziphantse zafana nezo zeenkampani ezihambele phambili zangaphandle.Nangona kunjalo, amanqanaba okungcangcazela kunye nengxolo yeemveliso ezinjalo kwilizwe lam akude nakwezo mveliso zangaphandle.Isizathu esiphambili yimpembelelo yokuvelisa kunye neemeko zokusebenza.Ukusuka kwimbono yoshishino oluthweleyo, iimeko zemeko yokusebenza zinokusombululwa ngokubeka phambili iimfuno ezifanelekileyo zenjini ephambili, kunye nendlela yokunciphisa ukungcangcazela kunye nengxolo ebangelwa yimiba yokuvelisa yingxaki ekufuneka isombulule ishishini lokuthwala.
Inani elikhulu leemvavanyo ekhaya nakwamanye amazwe libonise ukuba umgangatho wokulungiswa kweekheji, amakhonkco, kunye neebhola zentsimbi zinee-degrees ezahlukeneyo zempembelelo kwi-vibration.Phakathi kwabo, umgangatho wokucubungula weebhola zetsimbi unempembelelo ecacileyo kakhulu ekuthwaleni i-vibration, elandelwa ngumgangatho wokucubungula amakhonkco.Izinto ezibaluleke kakhulu zingqukuva, ukugungqa, uburhabaxa bomphezulu, amaqhuqhuva angaphezulu, njl.
Eyona ngxaki ibalaseleyo yeemveliso zebhola yentsimbi yelizwe lam kukuba ixabiso lokungcangcazela likhulu kwaye iziphene zomhlaba zinzulu (inqaku elinye, indawo yeqela, umgodi, njl.njl.).Nangona uburhabaxa bomphezulu, ubungakanani, imilo, kunye nempazamo azikho ngaphantsi kwinqanaba elingaphandle kwesangqa, ixabiso lokungcangcazela lokuthwala emva kokuhlanganisana liphezulu, kwaye lide livelise ingxolo engaqhelekanga.Iingxaki zobulunga bomatshini.Kwiringi, ukugungqa kwetshaneli kunye noburhabaxa bomphezulu zezona zinto zinzima ezichaphazela ukungcangcazela kwebheringi.Ngokomzekelo, xa ukujikeleza kwee-grooves zangaphakathi kunye nangaphandle kweebhola zebhola ze-groove ezincinci kunye neziphakathi zinkulu kune-2 μm, kuya kuba nefuthe elibalulekileyo kwi-vibration ye-bearing.Xa i-waviness ye-grooves yangaphakathi nangaphandle ingaphezu kwe-0.7 μm, ixabiso le-vibration ye-bearing liya kwanda ngokunyuka kwe-waviness.Umonakalo omkhulu kwi-grooves unokunyusa ukungcangcazela ngaphezu kwe-4 dB, kwaye uvelise izandi ezingaqhelekanga.Kungakhathaliseki ukuba yibhola yensimbi okanye i-ferrule, i-waviness iveliswa kwinkqubo yokugaya.Nangona ukugqiba okuphezulu kunokuphucula uburhabaxa kunye nokunciphisa uburhabaxa, owona mlinganiselo usisiseko kukunciphisa ukuphaphazela ngexesha lenkqubo yokugqiba kakhulu kwaye uthintele amaqhuma angaqhelekanga.Kukho imilinganiselo emibini engundoqo: Iibheringi zebhola zegroove ezinzulu zinciphisa ukungcangcazela
Enye kukunciphisa ukungcangcazela kokusila komphezulu kunye nokugqiba kakhulu ukufumana ukuchaneka kobume bomatshini obuchanekileyo kunye nomgangatho wokuthungwa komphezulu.Ukunciphisa ukungcangcazela, isixhobo somatshini wokugaya kakhulu kufuneka sibe nokumelana nokungcangcazela.Kwi-speed-speed grinding, amandla okugaya amancinci, umgca wokuwohloka kokugaya uncinci, akulula ukutshisa, kwaye unokuphucula ukuchaneka kwe-machining kunye nokusebenza kakuhle, okunempembelelo enkulu kwiibherethi zebhola eziphantsi;ukuqina okuguquguqukayo kunye nokuqina kwe-spindle kunye neempawu zayo zesantya zinempembelelo enkulu kwi-vibration yokusila yeebheringi zebhola eziphantsi.Ukuphakama kokuqina, isantya esincinci sokusila sitshintsha amandla okugaya, kwaye incinci i-vibration yenkqubo yokugaya;ubulukhuni bebherethi yokusonta buphuculwe, kwaye itekhnoloji ye-random dynamic balance isetyenziselwa ukuphucula ukuxhathisa kwe-vibration ye-spindle yokusila.Isantya sokungcangcazela kweentloko zokusila zangaphandle (ezifana neGamfior) simalunga nesinye kwishumi seso sophotho jikelele sasekhaya;kubaluleke kakhulu ukuphucula ukusebenza kokusika kunye nomgangatho wokunxiba we-oilstone yokusila.Okwangoku, eyona ngxaki iphambili yokusila i-oilstone yevili kwilizwe lam kukungafani kakuhle kwesakhiwo, echaphazela kakhulu umgangatho webhola ephantsi-ingxolo yokusila kunye nokugaya kakhulu;ukupholisa okwaneleyo ukuphucula ukuchaneka kokucoca;ukwandisa isisombululo sesondlo senkqubo yokutya ngokucokisekileyo kunye nokunciphisa inertia yokutya;ukugaya okufanelekileyo kunye ne-super-processing parameters kunye neenkqubo zokucubungula zizinto ezingenako ukuhoywa.Isibonelelo sokugaya kufuneka sibe sincinci, kwaye imilo kunye nokunyamezela isikhundla kufuneka kube ngqongqo.
Iibheringi zebhola zegroove ezinzulu ziphucula ukuchaneka
Okwesibini kukuphucula ukuchaneka kwendawo ye-machining datum kunye nokunciphisa impazamo kwinkqubo yokugaya.Idayamitha yangaphandle kunye nobuso bokuphela ziimbekiselo zokubeka kwinkqubo yokusila.Imposiso yembonakalo yedayamitha yangaphandle ukuya kwigroove superprecision igqithiswa ngokungathanga ngqo ngokubonakaliswa kwempazamo yedayamitha yangaphandle ukuya kumsele wokusila, kunye nokusila kwigroove ukuchaneka okuphezulu.Ukuba i-workpiece ihlanjululwe kwaye yonakaliswe ngexesha lokudluliselwa, iya kubonakaliswa ngokuthe ngqo kwi-raceway processing surface, eya kuchaphazela ukunyakaza kokuthwala.Ngoko ke, la manyathelo alandelayo kufuneka athathwe: ukuphucula ukuchaneka kwemilo yendawo yereferensi yokubeka;ukuhanjiswa kuhamba kakuhle ngexesha lokucubungula, ngaphandle kwamaqhuma;impazamo yemilo kunye nesikhundla sesibonelelo esingenanto akufunekanga sibe sikhulu kakhulu, ngakumbi xa isibonelelo sincinci, impazamo egqithileyo iya kubangela ukuchaneka kwemilo ekupheleni kokusila kunye nokugqiba okuphezulu kungaphuculwa kwiimfuno zomgangatho wokugqibela, nto leyo ebaluleke kakhulu. ichaphazela ukuhambelana komgangatho wokucubungula.
Ukususela kolu hlalutyo lungentla, akunzima ukubona ukuba imowudi yomgca ozenzekelayo eyenziwe ngumatshini ophezulu wokusebenza kunye nozinzo oluphezulu lwesixhobo somatshini yeyona ndlela ifanelekileyo yokugaya i-super-grinding iibheringi zebhola eziphantsi, ezinokuthi ziphephe ama-bumps, zinciphise iimpazamo zokudluliselwa. , Ukuphelisa izinto ezenziweyo, ukuphucula ukusebenza kakuhle kunye nokuhambelana komgangatho, ukunciphisa iindleko zemveliso, kunye nokuphucula izibonelelo zeshishini.
