Enqubweni yokusika ye-CNC, kunezizathu eziningi zamaphutha.Iphutha elibangelwa ukuphuma kwe-radial kwethuluzi kungenye yezinto ezibalulekile, ezithinta ngokuqondile umumo nengaphezulu elingafinyelelwa yithuluzi lomshini ngaphansi kwezimo ezifanele.Ekusikeni, kuthonya ukunemba, ukukhahlameza, ukungalingani kokugqoka kwamathuluzi kanye nezici zamathuluzi anamazinyo amaningi.Uma kukhulu ukuphuma kwe-radial kwethuluzi, isimo somshini wethuluzi singazinzi, futhi kuba nomthelela omkhulu kumkhiqizo.
Izimbangela zokuphuma kweRadial
Amaphutha okukhiqiza nawokubamba ethuluzi nezingxenye zokuphotha abangela ukukhukhuleka nokugqama phakathi kwe-eksisi yamathuluzi kanye ne-eksisi ekahle yokuzungezisa ye-spindle, kanye nobuchwepheshe obuthile bokucubungula nokusetshenziswa kwamathuluzi, okungase kubangele ukuphuma kwe-radial kwethuluzi lomshini wokugaya we-CNC ngesikhathi. ukucubungula.
1. Umthelela we-radial runout of spindle
Izizathu eziyinhloko zephutha le-radial runout ye-spindle yi-coaxiality, ukuthwala kwayo, i-coaxiality phakathi kwama-bearings, ukuchezuka kwe-spindle, njll.Lezi zici zakhiwa ohlelweni lokukhiqiza nokuhlanganisa ithuluzi lomshini, futhi kunzima ku-opharetha wethuluzi lomshini ukugwema ithonya labo.
2. Umehluko wokungahambisani phakathi kwesikhungo samathuluzi kanye nesikhungo sokujikeleza kwe-spindle
Uma ithuluzi lifakwe ku-spindle, uma isikhungo sethuluzi singahambisani nalokho, ithuluzi nakanjani lizobangela ukuphuma kwe-radial.Izici ezithile ezinomthelela yilezi: ukulingana kwethuluzi kanye ne-chuck, indlela yokulayisha ithuluzi kanye nekhwalithi yethuluzi ngokwalo.
3. Umthelela wobuchwepheshe obuthile bokucubungula
Okubangele ukuphuma kwe-radial aphoqa.Amandla okusika ama-radial yimikhiqizo ye-radial yamandla okusika aphelele.Izokwenza ukuthi i-workpiece igobe futhi ikhubaze futhi ikhiqize ukudlidliza kule nqubo.Ibangelwa ikakhulukazi izici ezifana nenani lokusika, ithuluzi kanye nempahla yokusebenza, indlela yokugcoba, i-engeli ye-geometric yethuluzi kanye nendlela yokucubungula.
Izindlela Zokunciphisa Ukuphuma Kweradial
Njengoba kushiwo ephuzwini lesithathu.Ukunciphisa amandla okusika i-radial kuyisimiso esibalulekile sokuyinciphisa.Izindlela ezilandelayo zingasetshenziswa ukunciphisa
1. Sebenzisa ithuluzi lokusika elibukhali
Khetha i-engeli yethuluzi elikhudlwana ukuze wenze ithuluzi libukhali ukunciphisa amandla okusika nokudlidliza.Khetha i-engeli enkulu yokususa ithuluzi ukuze unciphise ukungqubuzana phakathi kwendawo eyinhloko yokusula yethuluzi kanye nongqimba olunwebekayo lokutakula lwendawo yoguquko yendawo yokusebenza, ngaleyo ndlela wehlise ukudlidliza.Kodwa-ke, i-engeli ye-rake kanye ne-engeli yokususa yethuluzi ayikwazi ukukhethwa inkulu kakhulu, ngaphandle kwalokho amandla nendawo yokukhipha ukushisa yethuluzi ayanele.Ngakho-ke, kuyadingeka ukukhetha ama-engeli e-rake ahlukene kanye nama-angles okukhipha ithuluzi ngokusho kwesimo esithile.Umshini onzima ungaba mncane, kodwa ekuqedeni imishini, uma kucatshangelwa ukuthi ukunciphisa ukuphuma kwe-radial kwethuluzi, kufanele kube kukhudlwana ukwenza ithuluzi libukhali.
2. Sebenzisa amathuluzi okusika aqinile
Kunezindlela ezimbili eziyinhloko zokwandisa amandla ethuluzi lokusika.Enye iwukuba ukwandisa ububanzi besibambi.Ngaphansi kwamandla afanayo okusika ama-radial, ububanzi bomphathi wamathuluzi bukhuphuka ngo-20%, futhi ukuphuma kwe-radial kwethuluzi kungancishiswa ngo-50%.Okwesibili ukunciphisa ubude obuphumayo bethuluzi lokusika.Lapho ubude bethuluzi buba bukhulu, bukhulu ukuwohloka kwethuluzi ngesikhathi sokucubungula.Uma ukucubungula kushintsha njalo, kuzoqhubeka nokushintsha, okuholela ekukhiqizeni umsebenzi onzima.Ngokufanayo, ubude besandiso bethuluzi buncishiswa ngo-20%, buzophinde buncishiswe ngo-50%.
3. Ubuso bereki bethuluzi kufanele bushelelezi
Ngesikhathi sokucubungula, ubuso be-rake obushelelezi bunganciphisa ukungqubuzana kokusikwa okuncane ethuluzini, futhi kunganciphisa amandla okusika ethuluzini, ngaleyo ndlela kunciphise ukuphuma kwe-radial kwethuluzi.
4. Imbobo ye-spindle taper kanye nokuhlanza i-chuck
Imbobo ye-spindle taper kanye ne-chuck kuhlanzekile, futhi akufanele kube khona uthuli nemfucumfucu ekhiqizwa ekucutshungulweni.Lapho ukhetha ithuluzi lokwenza imishini, zama ukusebenzisa ithuluzi elinobude obufushane besandiso ukuze ulayishe, futhi amandla kufanele abe anengqondo futhi ngisho, angabi makhulu kakhulu noma abe mancane kakhulu.
5. Khetha ukuhlanganyela okunengqondo konqenqema lokusika
Uma ukubandakanyeka konqenqema lokusika kukuncane kakhulu, isenzakalo sokushibilika kwemishini sizokwenzeka, okuzobangela ukuguqulwa okuqhubekayo kokuphuma kwe-radial kwethuluzi ngesikhathi somshini, okuholela ebusweni obunzima.Uma ukubandakanyeka konqenqema lokusika kukhulu kakhulu, amandla amathuluzi anda.Kuzodala ukuguqulwa okukhulu kwethuluzi kanye nomphumela njengokufana okungenhla.
6. Sebenzisa ukugaya ekuqedeni
Njengoba indawo yegebe phakathi kwesikulufu somthofu namantongomane ishintsha ngesikhathi sokugaya phansi, izobangela ukuphakelayo okungalingani kwethebula lokusebenza, kubangele ukushaqeka nokudlidliza, kuthinte impilo yomshini nethuluzi kanye nobulukhuni obungaphezulu bocezu lokusebenza.Lapho u-up-milling, ubukhulu bokusika kanye nomthwalo wethuluzi nakho kuyashintsha kusuka kokuncane kuya kokukhulu, ukuze ithuluzi lizinze kakhulu ngesikhathi sokucubungula.Qaphela ukuthi lokhu kusetshenziselwa ukuqedela kuphela, futhi i-down Milling isasetshenziswa uma i-roughing.Lokhu kungenxa yokuthi ukukhiqizwa kokugaya phansi kuphezulu futhi impilo yesevisi yethuluzi ingaqinisekiswa.
7. Ukusetshenziswa okunengqondo koketshezi lokusika
Ukusetshenziswa okunengqondo koketshezi, ikakhulukazi isixazululo samanzi okupholisa, kunomphumela omncane ekunciphiseni amandla.Amafutha okusika umsebenzi wawo oyinhloko ukugcoba kunganciphisa kakhulu amandla okusika.Ngenxa yomphumela wayo wokugcoba, inganciphisa ukungqubuzana phakathi kobuso bereki yethuluzi kanye ne-chip naphakathi kobuso beflank kanye nendawo eguqukayo ye-workpiece, ngaleyo ndlela yehlise ukuphuma kweradial.Ukuzijwayeza kufakazele ukuthi inqobo nje uma ukunemba kokukhiqizwa nokuhlanganiswa kwengxenye ngayinye yomshini kuqinisekiswa, futhi inqubo enengqondo kanye namathuluzi akhethiwe, ithonya lokuphuma kwe-radial kwethuluzi ekubekezeleleni komshini we-workpiece kungaba incishisiwe.
