I-engeli ye-vertex ye-twist drillngokuvamile ingu-118°, kodwa ingabuye ibhekwe njengo-120°.Ngokuvamile ayikho inkinga uma ukwazi kahle la makhono angu-6 alandelayo okuqeqesha ukucija.
1.Ngaphambi kokugaya i-drill bit, i-main cutting edge ye-drill bit kanye nendawo yesondo lokugaya kufanele ibekwe endizeni evundlile, okusho ukuthi, lapho umkhawulo wokusika uthinta indawo yesondo lokugaya, lonke unqenqema kufanele lube phansi. .Lesi yisinyathelo sokuqala endaweni ehlobene ye-drill bit kanye nesondo lokugaya.Ngemva kokuba indawo isethiwe, izoncika kancane kancane ibheke endaweni yesondo lokugaya.
2.Le engeli ingaphambili le-engelii-drill bit.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, elingu-60°, ngokuvamile elinembe kakhudlwana.Lapha, kufanele kuqashelwe indawo evundlile ehlobene kanye nendawo eyi-angular ngaphambi kokuba i-drill ilole.Okubili kufanele kubhekwe njengento ephelele.Ungayizibi i-engeli yokusetha ngenjongo yokulinganisa i-edge yokusika, noma uzibe ukuleveliswa komkhawulo wokusika ngenjongo yokusetha i-engeli.
3.Ngemva kokuba i-cutting edge ithinte isondo lokugaya, kufanele igaywe kusukela enqenqemeni eyinhloko kuya ngemuva, okungukuthi, umkhawulo wokusika we-drill bit kuqala uthinta isondo lokugaya, bese ugaya kancane kancane phansi kulo lonke uhlangothi.Lapho i-drill bit ingena, thinta isondo lokugaya kancane, wenze ukulola okuncane kuqala, futhi unake ukubuka ukufana kwezinhlansi, lungisa ukucindezela esandleni ngesikhathi, futhi unake ukupholisa kwe-drill. kancane, ukuze ungakuvumeli ukuba kugaywe kakhulu, okwenza unqenqema lushintshe umbala, futhi lufakwe onqenqemeni.Lapho izinga lokushisa lomkhawulo wokusika litholakala liphezulu, i-drill bit kufanele ipholiswe ngesikhathi.
4.Lesi yisenzo sokugaya esijwayelekile.Unqenqema lokusika oluyinhloko kufanele lujike luye phezulu naphansi esondo lokugaya, okungukuthi, isandla esibambe ingaphambili le-drill kufanele sijikise ngokulinganayo i-drill phezulu naphansi endaweni yesondo lokugaya.Kodwa-ke, isandla esibambe isibambo akufanele sinyakaze, futhi isibambo sangemuva akufanele siphenduke, okungukuthi, umsila we-drill bit awukwazi ukuphakanyiswa ngaphezu komugqa ovundlile wesondo lokugaya, ngaphandle kwalokho umkhawulo wokusika uzofiphala futhi ayikwazi ukusika.Lesi isinyathelo esibucayi kakhulu.Ukuthi i-drill bit igqokwe kahle noma cha ihlobene kakhulu nayo.Lapho ukugaya sekuzoqedwa, qala kusukela onqenqemeni lwensingo futhi uyihlikihle kancane ubheke ekhoneni elingemuva ukuze wenze ingemuva le-blade libe bushelelezi.
1.Ngemva kokugaya unqenqema olulodwa, gaya omunye umkhawulo wokusika.Kumele kuqinisekiswe ukuthi umkhawulo wokusika uphakathi kwe-axis ye-drill bit, futhi imiphetho yokusika ezinhlangothini zombili kufanele ibe yi-symmetrical.Izingcweti ezinolwazi zizobheka ukulinganisa kwephuzu lokubhoboza ngaphansi kokukhanya okukhanyayo, bese belilola kancane.I-engeli yokusiza ye-edge yokusika ye-drill ngokuvamile ingu-10°-14°.Uma i-angle yokusiza inkulu, umkhawulo wokusika uncane kakhulu, futhi ukudlidliza kunzima ngesikhathi sokumba.Imbobo ingunxantathu noma i-pentagonal, futhi i-chip inesimo senaliti;i-angle yokusiza incane, Uma ubhoboza, amandla e-axial makhulu kakhulu, akulula ukusika, amandla okusika ayanda, izinga lokushisa liphezulu, ikhanda lokubhoboza liyashisa kakhulu, futhi akunakwenzeka ngisho nokubhola.I-angle yangemuva ilungele ukugaya, indawo yangaphambili igxile, futhi imiphetho emibili i-symmetrical.Lapho ubhoboza, i-i-drill bitingasusa ama-chips kalula, ngaphandle kokudlidliza, futhi ububanzi bembobo ngeke bunwebe.
2.Ngemva kokugaya imiphetho emibili, naka ukulola ichopho lei-drill bit enobubanzi obukhudlwana.Ngemva kokuba imiphetho emibili ye-drill bit isiloliwe, kuzoba khona indawo eyisicaba ekugcineni kwemiphetho emibili, okuzothinta ukuma okuphakathi kwe-drill bit.Kudingekile ukuthi u-chamfer ekhoneni ngemuva konqenqema ukwenza indawo eyisicaba yethiphu yonqenqema ibe mncane ngangokunokwenzeka.Indlela yokubeka i-drill bit iqonde, iqondanise nekhona lesondo lokugaya, bese uthela i-groove encane empandeni ngemuva kwe-blade ngokumelene nesihloko se-blade.Leli futhi iphuzu elibalulekile le-drill centering kanye nokusika ukukhanya.Qaphela ukuthi lapho ugaya i-chamfer ye-tip enqenqemeni, akufanele igaywe onqenqemeni oluyinhloko lokusika.Lokhu kuzokwenza i-engeli ye-rake yonqenqema oluyinhloko ibe mkhulu kakhulu, okuzothinta ngokuqondile ukubhola.
