Emishinini ye-CNC, kukhona abasiki abahlukahlukene bokugaya, njengeEnd Mill, I-Roughing End Mill, Ukuqeda End Mill, Ball End Mill, nokunye.Isiqondiso sokuzungezisa kwesisiki sokugaya ngokuvamile sihlala njalo, kodwa isiqondiso sokuphakelayo siyahlukahluka.Kunezimo ezimbili ezivamile ekugayweni kokugaya: ukugaya phambili kanye nokugaya emuva.
Umkhawulo wokusika we-milling cutter ungaphansi kwemithwalo yomthelela njalo lapho inqamula. Ukuze kuzuzwe ukugaya okuphumelelayo, kuyadingeka ukucabangela ukuthintana okulungile phakathi komkhawulo wokusika kanye nempahla ngesikhathi sokusika nangesikhathi sokusika.Enqubweni yokugaya, i-workpiece idliswa ngendlela efanayo noma ephambene kuya lapho kujikeleza khona i-milling cutter, okuthinta ukusika ngaphakathi nangaphandle kwenqubo yokugaya, kanye nokuthi kufanele kusetshenziswe izindlela zokugaya phambili noma emuva.
1. Umthetho Wegolide Wokugaya - Ukusuka Okuwugqinsi Ukuya Kuncane
Lapho ukugaya, kubalulekile ukucabangela ukwakheka kwama-chips.Isici esinqumayo sokwakheka kwe-chip isikhundla somshini wokusika, futhi kubalulekile ukulwela ukwenza ama-chips aminyene lapho i-blade isika phakathi kanye nama-chips amancane lapho i-blade isika ukuze kuqinisekiswe inqubo yokugaya ezinzile.
Khumbula umthetho wegolide wokugaya, "kusuka kokuminyene kuya kokuncane," ukuze uqinisekise ukuthi ubukhulu bama-chips lapho unqenqema lokusika lunqunywa buncane ngangokunokwenzeka.
2. Ukugaya phambili
Ekugayeni phambili, ithuluzi lokusika lidliswa ngendlela yokujikeleza.Inqobo nje uma ithuluzi lomshini, i-fixture, ne-workpiece kuvumela, ukugaya phambili kuhlale kuyindlela ethandwayo.
Ekugayeni onqenqemeni, ubukhulu be-chip buzokwehla kancane kancane kusukela ekuqaleni kokusika kuye ku-zero ekupheleni kokusika.Lokhu kungavimbela unqenqema lokusika ukuthi lunganwaya futhi luhlikihle ingaphezulu lengxenye ngaphambi kokubamba iqhaza ekusikeni.
Ukushuba kwe-chip enkulu kunenzuzo, njengoba amandla okusika evame ukudonsa ucezu lomsebenzi kusisiki sokugaya, ukugcina ukusika onqenqemeni.Kodwa-ke, ngenxa yokuba lula kwesisiki sokugaya sidonselwa endaweni yokusebenza, ithuluzi lomshini lidinga ukuphatha igebe lokuphakelayo lebhentshi lokusebenza ngokususa ukuhlehla.Uma i-milling cutter idonselwa kucezu lokusebenza, okuphakelayo kuzokwanda ngokungalindelekile, okungase kuholele ekugqileni okukhulu kwe-chip kanye nokuphuka konqenqema.Kulezi zimo, cabanga ukusebenzisa i-reverse milling.
3. Ukugaya kabusha
Ekugayeni okuphambene, isiqondiso sokuphakelayo sethuluzi lokusika siphambene nesiqondiso salo sokuzungezisa.
Ubukhulu be-chip bukhula kancane kancane ukusuka ku-zero kuze kube sekupheleni kokusika.Unqenqema lokusika kufanele luphoqeleke ukuba lunqamule phakathi, ukuze lukhiqize umphumela wokuklwebheka noma wokupholisha ngenxa yokungqubuzana, izinga lokushisa eliphezulu kanye nokuxhumana njalo nomsebenzi oqinile obangelwa unqenqema lokusika lwangaphambili.Konke lokhu kuzofinyeza impilo yamathuluzi.
Ama-chips aminyene namazinga okushisa aphakeme akhiqizwa ngesikhathi sokusika i-cutting Edge kuzoholela ekucindezelekeni okuphezulu, okuzofinyeza impilo yamathuluzi futhi ngokuvamile kubangele ukulimala okusheshayo onqenqemeni lokusika.Kungase futhi kubangele ama-chips ukuthi anamathele noma ashise onqenqemeni lokusika, okuzobe sekuwathwala awayise lapho aqala khona ukusikwa okulandelayo, noma enze ukuthi unqenqema lokusika luhlakazeke ngokushesha.
Amandla okusika avame ukusunduza i-milling cutter kude nendawo yokusebenza, kuyilapho amandla e-radial evame ukuphakamisa ucezu lokusebenza ebhentshini lokusebenza.
Uma kunoshintsho olubalulekile emvuzweni yokwenza imishini, ukugaya okubuyela emuva kungase kube nenzuzo enkulu.Uma usebenzisa ukufakwa kwe-ceramic ukucubungula ama-superalloys, kuyanconywa futhi ukusebenzisa i-reverse milling, ngoba i-ceramics izwela umthelela owenziwe lapho usika ku-workpiece.
4. Indawo yokusebenza
Isiqondiso sokuphakelayo sethuluzi lokusika sinezidingo ezihlukene ze-workpiece fixture.Phakathi nenqubo yokugaya, kufanele ikwazi ukumelana nokuphakamisa amandla.Phakathi nenqubo yokugaya, kufanele ikwazi ukumelana nokucindezela okuya phansi.
Amathuluzi okusika we-OPT ungumphakeli wekhwalithi ephezulu wabasiki be-Carbide milling.
Siyakusekela ekuthengeni izidingo zakho zonyaka ngamanani ancintisanayo, sikunikeza ikhwalithi ephezulu kanye nohlu olubanzi lwezinsizakalo.
