Ukuze ugaye i-twist drillngokucijile futhi ususe ama-chips, unake amaphuzu ambalwa: 1. Umkhawulo wokusika kufanele ube nezinga nendawo yesondo lokugaya.Ngaphambi kokugaya i-i-drill bit, umkhawulo oyinhloko wokusika we-drill bit kanye nendawo yesondo lokugaya kufanele ibekwe endizeni enezingqimba, okungukuthi, ukuqinisekisa ukuthi lonke unqenqema kufanele lube phansi lapho unqenqema lokusika luthinta indawo yesondo lokugaya.Lesi yisinyathelo sokuqala endaweni ehlobene ye-i-drill bitkanye neisondo lokugaya.Ngemva kokusetha indawo, ihanjiswa kancane kancane endaweni yesondo lokugaya.2. I-axis ye-drill bit kufanele ithambekele nge-engeli engu-60 ° ebusweni besondo lokugaya.Le engeli iyi-engeli ebukhali yebhithi yokubhoboza.Uma i-engeli ingalungile ngalesi sikhathi, izothinta ngokuqondile usayizi we-engeli ephezulu ye-drill bit, umumo we-main cutting edge kanye ne-bevel angle ye-chisel edge.Lokhu kubhekisela ebudlelwaneni bendawo phakathi kwe-eksisi yebhithi yokubhola kanye nengaphezulu lesondo lokugaya.Kwanele ukuthatha u-60 °.Le engeli ngokuvamile inembe kakhudlwana.Lapha, kufanele kuqashelwe indawo evundlile ehlobene kanye nendawo eyi-angular ye-drill bit ngaphambi kokulola.Okubili kufanele kucatshangelwe.Ungayizibi i-engeli ye-cutting edge ukuze usethe i-edge yokusika, noma ungayinaki i-edge yokusika ukuze usethe i-engeli.
5. Qinisekisa ukuthi ithiphu le-blade lihambisana ne-eksisi, futhi izinhlangothi zombili zinokulinganisa futhi zilungiswa kancane.Ngemuva kokugaya unqenqema olulodwa lwe-drill, bese ugaya olunye unqenqema.Kumele kuqinisekiswe ukuthi unqenqema luphakathi kwe-axis ye-drill, futhi imiphetho ezinhlangothini zombili kufanele ibe yi-symmetrical.Izingcweti ezinolwazi zizobheka ukulinganisa kwephuzu lokubhoboza ngokukhanya okukhanyayo bese ligaya kancane.I-engeli yokususa yomkhawulo wokusika we-drill ngokuvamile ingu-10°-14°.Uma i-angle yokukhipha i-angle inkulu, umkhawulo wokusika uncane kakhulu, ukudlidliza kunzima ngesikhathi sokubhoboza, imbobo i-trilateral noma i-pentagonal, futhi ama-chips afana nenaliti;i-angle yokususa incane, Lapho ubhoboza, amandla e-axial makhulu, akulula ukusika, amandla okusika ayanda, izinga lokushisa liyakhuphuka, i-drill ishisa kakhulu, futhi ayikwazi ngisho nokubhobozwa.I-angle yokususa ifanele ukugaywa, ingaphambili nethiphu kugxiliswe phakathi, futhi imiphetho emibili i-symmetrical.Lapho ubhoboza, i-i-drill bitisusa ama-chips kalula, ngaphandle kokudlidliza, futhi ububanzi bembobo ngeke bunwebe.6. Ngemva kokuba imiphetho emibili icijile, qaphela ukuqinisa ichopho le-drill bit enobubanzi obukhulu.Ngemva kokuba imiphetho emibili yokubhoboza isiloliwe, kuzoba khona indawo eyisicaba esiqongweni semiphetho emibili, okuzothinta ukuma okuphakathi kwendawo yokubhoboza.Kudingekile uku-chamfer ekhoneni ngemuva konqenqema ukuze wenze indawo eyisicaba yonqenqema ibe mncane ngangokunokwenzeka.Indlela yokumisa i-drill bit, iqondanise nekhona lesondo lokugaya, futhi uthele i-groove encane esihlokweni se-blade empandeni ngemuva kwensingo.Leli futhi iphuzu elibalulekile ukuze i-drill igxile futhi isikwe kancane.Qaphela ukuthi lapho ugaya i-chamfering yonqenqema, ungayigayi emaphethelweni amakhulu okusika, okuzokwenza i-rake angle ye-main cutting edge ibe nkulu kakhulu, okuzothinta ngokuqondile ukubhoboza.Ayikho ifomula ethile yokugaya izingcezu zokugaya.Kuyadingeka ukuqoqa ulwazi ekusebenzeni kwangempela.Ngokuqhathanisa, ukubuka, nokuhlola okuphindaphindiwe, izingcezu zokubhoboza zizololwa kangcono.
3. Gaya ingemuva kusukela onqenqemeni lokusika.Ngemuva kokuthi isondo lokusika lithinta isondo lokugaya, kufanele ligaywe kusukela onqenqemeni oluyinhloko kuya ngemuva, okungukuthi, umkhawulo wokusika we-drill bit uzothinta kuqala isondo lokugaya, bese ugaya kancane kancane phansi kulo lonke uhlangothi.Lapho i-drill bit inqunywa, ingathinta kancane isondo lokugaya, iqale yenza inani elincane lokulola, futhi inake ukubuka ukufana kwenhlansi, ilungise ukucindezela esandleni ngesikhathi, futhi unake ukupholisa i-drill bit, ukuze ungakuvumeli ukugaya kakhulu, okubangela ukuthi umkhawulo wokusika ushintshe umbala , futhi ufakwe emaphethelweni.Uma kutholakala ukuthi izinga lokushisa lomkhawulo wokusika liphezulu, i-drill kufanele ipholile ngesikhathi.4. I-cut cut of the drill kufanele isuke phezulu naphansi, futhi umsila we-drill akufanele uphenduke.Lesi yisenzo sokugaya esijwayelekile.Unqenqema lokusika oluyinhloko kufanele lujike luye phezulu naphansi esondweni lokugaya, okungukuthi, isandla esibambe ingaphambili lebhithi yokubhoboza kufanele sijikise ngokulinganayo ibhithi yokubhoboza iye phezulu naphansi endaweni yesondo lokugaya.Kodwa-ke, isandla esibambe isibambo asikwazi ukushwibeka, futhi isibambo sangemuva kufanele sivinjwe ukuthi sikhuphukele phezulu, okungukuthi, umsila we-drill akufanele uphakanyiswe ngaphezu komugqa ovundlile wesondo lokugaya, ngaphandle kwalokho unqenqema lokusika luzoba buthuntu. futhi ayikwazi ukunqunywa.Lesi yisinyathelo esibucayi kakhulu, futhi ukuthi i-drill igaywe kahle noma cha ihlobene kakhulu nakho.Lapho ukugaya sekuzoqedwa, qala kusukela onqenqemeni lwensingo futhi uyihlikihle kancane ubheke ekhoneni elingemuva ukuze wenze ingemuva le-blade libe bushelelezi.
