Ukuguqula kusebenzisa okungaguquki kunokuzungezisa amathuluzi ngoba ukuphenduka kuzungezisa ucezu lokusebenza, hhayi ithuluzi.Amathuluzi okuguqula ngokuvamile ahlanganisa okufakwayo okushintshekayo kumzimba wethuluzi eliphendukayo.Ama-blades ahlukile ngezindlela eziningi, kufaka phakathi ukuma, impahla, isiphetho kanye nejometri.Umumo ungaba yindilinga ukuze ukhulise amandla onqenqema, umumo wedayimane ukuze iphuzu livumele ukusika imininingwane emihle, noma isikwele noma i-octagonal ukuze kwandiswe inani lamaphethelo angawodwana angasetshenziswa njengoba unqenqema olulodwa luguga ngemva kolunye.Impahla ivamise ukuba yi-carbide, kodwa ukufakwa kwe-ceramic, i-cermet noma kwedayimane kungasetshenziswa.Izembatho ezihlukahlukene zokuzivikela zisiza futhi lezi zinto ze-blade ukusika ngokushesha futhi zihlale isikhathi eside.
Lolu shintsho olulula endleleni yamathuluzi ku-lathe yesitayela saseSwitzerland lungathuthukisa kakhulu amandla ayo okulawula i-chip.
Ukuphenduka kusebenzisa i-lathe ukuze kukhishwe okokusebenza ngaphandle kwendawo yokusebenza ephendukayo, kuyilapho okuyisicefe kususa okubalulekile ngaphakathi kwendawo yokusebenza ejikelezayo.
Uma kubhekwa izidingo ezikhulayo zokuqedwa, ifomula entsha ye-cubic boron nitride ingase ibe enye indlela ethembeke kakhudlwana kune-carbide enosimende.
Lezi zici zisiza ukuthuthukisa ukuzinza kwamathuluzi okusika, ukwenza kube sezingeni ukusebenza kokusika, nokwelula impilo yamathuluzi, okuvumela ama-workshops ukuthi asebenze ngaphandle kokugadwa ngokuzethemba.
Abacwaningi be-UNCC bethula ukuguquguquka kube izindlela zamathuluzi.Umgomo bekuwukuphulwa kwe-chip, kodwa izinga eliphezulu lokususwa kwensimbi laliwumphumela oseceleni othakazelisayo.
Ama-chipbreaker ahlukene aklanyelwe imingcele ehlukene.Icubungula ividiyo ekhombisa umehluko ekusebenzeni kahle phakathi kwama-chipbreaker asetshenziswa ezinhlelweni ezilungile nezingalungile.
Ukuphenduka kuyinqubo yokukhipha impahla kububanzi obungaphandle bomsebenzi ojikelezayo usebenzisa i-lathe.Abasiki bephuzu elilodwa basika insimbi besuka kucezu lokusebenza baba (okungcono) ama-chips amafushane, abukhali okulula ukuwasusa.
Amathuluzi asekuqaleni okujika kwakuyizicucu eziqinile eziwunxande ezenziwe ngensimbi enesivinini esikhulu ezinereki namakhona okuvula ekugcineni.Lapho ithuluzi liba buthuntu, umkhandi wezikhiye uyalilola emshinini wokugaya ukuze lisetshenziswe ngokuphindaphindiwe.Amathuluzi e-HSS asavamile kumalebula amadala, kodwa amathuluzi e-carbide asedume kakhulu, ikakhulukazi efomini lephuzu elilodwa elibrazed.I-Carbide inokumelana nokugqokwa okungcono kanye nobulukhuni, okwandisa ukukhiqiza nempilo yamathuluzi, kodwa ibiza kakhulu futhi idinga ulwazi ukuze igaywe kabusha.
Ukuphenduka kuyinhlanganisela yomugqa (ithuluzi) kanye nokunyakaza okujikelezayo (ucezu lokusebenza).Ngakho-ke, isivinini sokusika sichazwa njengebanga lokujikeleza (elibhalwe ngokuthi sfm - surface foot ngomzuzu - noma smm - imitha yesikwele ngomzuzu - ukunyakaza kwephuzu ebusweni bengxenye ngomzuzu owodwa).I-feedrate (evezwa ngamayintshi noma amamilimitha ngokuphenduka ngakunye) ibanga eliwumugqa ithuluzi elihamba ngalo noma phezu kwendawo yokusebenza.Okuphakelayo nakho kwesinye isikhathi kuvezwa njengebanga eliwumugqa (in/min noma mm/min) elihamba ithuluzi ngomzuzu owodwa.
Izidingo zezinga lokuphakelayo ziyahlukahluka kuye ngenjongo yokusebenza.Isibonelo, ekuqineni, okuphakelayo okuphezulu kuvame ukuba ngcono ukuze kukhuliswe amazinga okukhishwa kwensimbi, kodwa ukuqina kwengxenye ephezulu namandla omshini kuyadingeka.Ngesikhathi esifanayo, ukuqedela ukujika kunganciphisa izinga lokuphakelayo ukuze kuzuzwe ubulukhuni obucaciswe engxenyeni yomdwebo.
I-Boring isetshenziselwa ikakhulukazi ukuqedela izimbobo ezinkulu ezingenalutho ekubunjweni noma ukubhoboza izimbobo kuma-forgings.Amathuluzi amaningi afana namathuluzi okuguqula angaphandle endabuko, kodwa i-engeli yokusika ibaluleke kakhulu ngenxa yezinkinga zokukhishwa kwe-chip.
I-spindle esikhungweni esiphendukayo iqhutshwa ngebhande noma ishayelwa ngokuqondile.Ngokuvamile, ama-spindle aqhutshwa ngamabhande ubuchwepheshe obudala.Ziyasheshisa futhi zehlise ukusheshisa kancane kakhulu kunama-spindles aqondile, okusho ukuthi izikhathi zomjikelezo zingaba zinde.Uma wenza izingxenye zobubanzi obuncane, isikhathi esidingekayo ukuze uvule i-spindle ukusuka ku-0 kuye ku-6000 revolutions side kakhulu.Eqinisweni, ukufinyelela kuleli jubane kungathatha isikhathi esiphindwe kabili kune-direct drive spindle.
Ama-spindle ashayelwa ngamabhande angase abe namaphutha amancane okuma ngenxa yokubambezeleka kwebhande phakathi kwedrayivu nesishumeki.Lokhu akusebenzi kuma-spindle wedrayivu owakhelwe ngaphakathi.Ukusetshenziswa kwe-spindle yedrayivu eqondile yesivinini sokuphakamisa okuphezulu kanye nokunemba kokuma kuyinzuzo enkulu uma usebenzisa ukunyakaza kwe-C-axis emishinini yamathuluzi ashayelwa.
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 driven.Ama-tailstocks e-Servo ayasebenza, kodwa isisindo sawo singanqunyelwa.Imvamisa, i-hydraulic tailstocks inekhanda eliphumayo elinamayintshi angu-6 ohambo.I-spindle nayo inganwetshwa ukuze isekele ama-workpieces asindayo futhi isebenzise amandla amaningi kune-servo tailstock.
Amathuluzi abukhoma avame ukubhekwa njengesixazululo se-niche, kodwa izinqubo eziningi ezahlukene zingathuthukiswa ngokusebenzisa ukuqaliswa kwamathuluzi abukhoma.#isisekelo
I-Kennametal KYHK15B grade kubikwa ukuthi inokujula okukhulu kokusikwa kunokufakwa kwe-PcBN ezinsimbi eziqinile, ama-superalloy nensimbi ekhonjiwe.
U-Walter unikeza amamaki amathathu e-Tiger tec Gold athuthukiswe ngokukhethekile ukuphenduka kwensimbi nensimbi.
Ama-lathes angobunye bobuchwepheshe bemishini endala kakhulu, kodwa kusekuhle ukugcina izinto eziyisisekelo engqondweni lapho uthenga i-lathe entsha.#isisekelo
I-Walter cermet turning inserts yakhelwe ukunemba kobukhulu, ukuqedwa kwengaphezulu okuhle kakhulu kanye nokudlidliza okuncishisiwe.
Ngenxa yokuthi awekho amazinga omhlaba wonke achaza amamaki e-carbide noma izinhlelo zokusebenza, abasebenzisi kumele bathembele ekuhlakanipheni okuvamile kanye nolwazi oluyisisekelo ukuze baphumelele.#isisekelo
Ukufakwa kwe-carbide okusha okujwayelekile kwe-ISO-P okujwayelekile okuvela ku-CERATIZIT kulungiselelwe izimo ezithile zokukhiqiza.
