Ukuphenduka kusebenzisa ithuluzi elinganyakazi nelingaphenduki ngoba ngesikhathi sokuphenduka wucezu lokusebenza oluzungezayo, hhayi ithuluzi.Amathuluzi okuguqula ngokuvamile ahlanganisa okufakwayo okungashintshaniswa ngaphakathi komzimba wethuluzi elijikayo.Ama-blades ahlukile ngezindlela eziningi, kufaka phakathi ukuma, impahla, ukunamathela kanye nejometri.Umumo ungaba yindilinga ukuze ukhulise amandla onqenqema, umumo wedayimane ukuze ithiphu ebukhali ingakwazi ukusika izingxenye ezithambile, noma isikwele noma i-octagonal ukuze kwandiswe inani lemiphetho ngayinye engasetshenziswa njengoba unqenqema lugqoka.Izinto ezisetshenziswayo ngokuvamile ziyi-carbide, kodwa i-ceramic, insimbi ene-sintered noma ukufakwa kwedayimane nakho kuyatholakala ngezinhlelo zokusebenza ezifunwa kakhulu.Izembatho ezihlukahlukene zokuzivikela zisiza futhi lezi zinto ze-blade ukusika ngokushesha futhi zihlale isikhathi eside.
Ukuphenduka kusebenzisa i-lathe ukuze kukhishwe okokusebenza ngaphandle kwendawo yokusebenza ephendukayo, kuyilapho okuyisicefe kususa okubalulekile ngaphakathi kwendawo yokusebenza ejikelezayo.
Njengoba izidingo zokuqeda ziba zimbi kakhulu, ukwakheka okusha kwe-cubic boron nitride kungase kunikeze enye indlela ethembeke kakhudlwana ku-carbide.
Lezi zici zisiza ukuthuthukisa ukuzinza kwamathuluzi okusika, ukwenza kube sezingeni ukusebenza kokusika, nokwelula impilo yamathuluzi, okuvumela izitolo ukuthi zisebenze zingagadiwe ngokuzethemba.
Abacwaningi be-UNCC bethula ukuguquguquka kube izindlela zamathuluzi.Umgomo ukuphulwa kwe-chip, kodwa amazinga aphezulu okukhishwa kwensimbi awumphumela othakazelisayo.
Ama-chipbreaker ahlukene aklanyelwe imingcele ehlukene.Amavidiyo acutshungulwayo akhombisa umehluko ekusebenzeni phakathi kwama-chipbreaker asetshenziselwa izinhlelo zokusebenza ezifanele nezingalungile.
Ama-clamp ama-machine anezingubo ezihlukene ngesikhathi sokugoqa nokuqedwa kubonisa ukuthi ukukhetha ukunamathela okulungile kungaba nomthelela omkhulu ekusebenzeni kwenqubo.
Ukuphenduka kuyinqubo yokukhipha impahla kububanzi obungaphandle bomsebenzi ojikelezayo usebenzisa i-lathe.Amathuluzi anephuzu elilodwa asika insimbi esuka kucezu lokusebenza abe (okufanele) abe amashiphu amafushane, acwebile, akhipheka kalula.
Amathuluzi okuqala okujika kwakuyizicucu eziqinile eziwunxande zensimbi enesivinini esikhulu ezinereki ne-engeli yokususa ekugcineni.Lapho ithuluzi liba buthuntu, omakhenika bayalilola emshinini wokugaya ukuze liphinde lisetshenziswe.Amathuluzi ensimbi anesivinini esikhulu asavamile kuma-lathe amadala, kodwa amathuluzi e-carbide asedume kakhulu, ikakhulukazi efomini lephoyinti elilodwa eliqinile.I-Carbide inokumelana nokugqokwa okungcono kanye nobulukhuni, okwandisa ukukhiqiza nempilo yamathuluzi, kodwa ibiza kakhulu futhi idinga ulwazi ukuze ilole.
Ukuphenduka kuyinhlanganisela yokunyakaza (ithuluzi) kanye ne-rotary (workpiece).Ngakho-ke, isivinini sokusika sichazwa njengebanga lokuzungeza (elibhalwe ngokuthi sfm - izinyawo ezingaphezulu ngomzuzu - noma smm - square metres ngomzuzu - ukunyakaza kwephoyinti ebusweni bengxenye ngomzuzu owodwa).Izinga lokuphakelayo (elibhalwe ngama-intshi ngamasentimitha ngokuphenduka ngakunye noma ngamamilimitha) yibanga lomugqa ithuluzi elihamba eduze noma phezu kwendawo yokusebenza.Okuphakelayo nakho kwesinye isikhathi kuvezwa njengebanga elihanjwa yithuluzi ngomzuzu owodwa (amayintshi ngomzuzu noma amamilimitha ngomzuzu).
Izidingo zezinga lokuphakelayo ziyahlukahluka kuye ngenjongo yokusebenza.Isibonelo, ekuqineni, okuphakelayo okuphezulu kuvame ukufaneleka kangcono ekukhuliseni amazinga okususwa kwensimbi, kodwa kudinga ukuqina kwengxenye ephezulu namandla omshini.Ngesikhathi esifanayo, ukuqeda kunganciphisa izinga lokuphakelayo ukuze kufinyelelwe ekuqedeni okungaphezulu okushiwo engxenyeni yomdwebo.
I-Boring isetshenziswa ngokuyinhloko ukukhanda izimbobo ezinkulu ezingenalutho kuma-castings noma ukubhoboza izimbobo kuma-forgings.Amathuluzi amaningi afana namathuluzi okuguqula endabuko, kodwa i-engeli yokusika ibaluleke kakhulu ngenxa yezinkinga zokugeleza kwe-chip.
I-spindle esikhungweni esiphendukayo iqhutshwa ngebhande noma ishayelwa ngokuqondile.Ngokuvamile, ama-spindle aqhutshwa ngamabhande ubuchwepheshe obudala.Ziyasheshisa futhi zehle ngokushesha kunama-spindles aqondile, okusho ukuthi izikhathi zomjikelezo zingaba zinde.Uma uphendula ingxenye yobubanzi obuncane, isikhathi esidingekayo ukuze ujike i-spindle sisuke ku-0 siye ku-6000 rpm side kakhulu.Eqinisweni, isikhathi esidingekayo ukuze kufinyelelwe lesi sivinini singaba yinde ngokuphindwe kabili kune-direct drive spindle.
Ama-spindle ashayelwa ngamabhande angase abe namaphutha amancane okuma ngenxa yokusaleleka kwebhande phakathi kwedrayivu nesishumeki.Lokhu akusebenzi ekuqondiseni ama-spindle aqinile.Izivinini eziphakeme ezikhuphukayo kanye nokunemba kokuma okuphezulu lapho usebenzisa i-direct drive spindle kuyizinzuzo ezibalulekile uma usebenzisa ukunyakaza kwe-C-axis emishinini yamathuluzi abukhoma.
I-tailstock ye-CNC ehlanganisiwe iyisici esibalulekile sezinqubo ezizenzakalelayo.I-tailstock ehlelekayo ngokugcwele inikeza ukuqina okukhulayo nokuzinza kokushisa.Nokho, i-cast tailstock ingeza isisindo emshinini.
Kunezinhlobo ezimbili eziyinhloko zama-tailstocks ahlelekayo-i-servo-driven kanye ne-hydraulic.I-Servo tailstocks ilula, kodwa isisindo sayo singanqunywa.Ngokuvamile, i-hydraulic tailstock ine-telescopic bushing ene-intshi engu-6 yokuhamba.I-spindle inganwebeka futhi isekele ama-workpieces asindayo futhi isebenzise amandla angaphezu kwe-servo tailstock.
Amathuluzi wamandla avame ukubonwa njengesixazululo se-niche, kodwa ukuqaliswa kwawo kungathuthukisa izinqubo eziningi ezahlukene.#isisekelo
Ibanga le-Kennametal KYHK15B kubikwa ukuthi linikeza ukujula okukhulu kunokufakwa kwe-PcBN lapho kwenziwa izinsimbi eziqinile, ama-superalloy nezinsimbi ezisansimbi.
U-Walter unikeza amamaki Egolide amathathu e-Tiger·tec, athuthukiswe ngokukhethekile ukuphendulela insimbi nensimbi yokusansimbi.
Amalebula angobunye bobuchwepheshe bemishini endala kakhulu, kodwa kusekuhle ukukhumbula izinto eziyisisekelo lapho ucabangela ukuthenga i-lathe entsha.#isisekelo
Okufakiwe kwe-cermet ka-Walter kuklanyelwe ukunemba kobukhulu, ikhwalithi ephezulu kakhulu kanye nokudlidliza okuncishisiwe.
Njengoba zingekho izindinganiso zamazwe ngamazwe ezichaza amamaki e-carbide noma ububanzi bezicelo, abasebenzisi kufanele bathembele ekwahluleleni nasolwazini oluyisisekelo ukuze bathole impumelelo.#isisekelo
Ukufakwa okusha kwe-ISO-P carbide kwe-Ceratizit okunoqweqwe olujwayelekile kulungiselelwe izimo ezithile zokukhiqiza.
