I-Drill bit, njengethuluzi elivame kakhulu ekucubunguleni imigodi, isetshenziswa kabanzi ekukhiqizeni imishini, ikakhulukazi ukucubungula izimbobo kumadivayisi okupholisa, amashidi amashubhu wemishini yokuphehla amandla, amajeneretha omusi nezinye izingxenye.
1,Izici zokumba
I-drill bit ngokuvamile inemiphetho emibili yokusika.Ngesikhathi somshini, i-drill bit iyajikeleza futhi isike ngesikhathi esifanayo.I-engeli yangaphambili ye-drill bit iba nkulu futhi ibe nkulu ukusuka eksisi emaphakathi kuya onqenqemeni olungaphandle, ijubane lokusika le-drill bit eliseduze nendilinga yangaphandle liphakeme, futhi isivinini sokusika siyehla sibheke enkabeni, kanye nesivinini sokusika isikhungo esijikelezayo sika-drill bit singuziro.Unqenqema oluvundlile lwe-drill luseduze ne-axis yesikhungo esijikelezayo.Unqenqema oluseceleni lune-engeli enkulu ye-rake eyi-axiliary, ayikho indawo ye-chip, nesivinini esiphansi sokusika, ngakho-ke izokhiqiza ukumelana okukhulu kwe-axial.Uma unqenqema oluphambene lugaywa ukuze uthayiphe u-A noma u-C ku-DIN1414, futhi umkhawulo wokusika eduze kwe-axis ephakathi une-angle ye-rake enhle, ukumelana nokusika kungancishiswa futhi ukusebenza kokusika kungathuthukiswa kakhulu.
Ngokuya ngobujamo obuhlukene, izinto zokwakha, izakhiwo, imisebenzi, njll. yezingxenye zokusebenza, izingcezu zokubhola zingahlukaniswa zibe izinhlobo eziningi, njengezinsimbi zokubhola zensimbi ezinesivinini esikhulu (i-fried dough twist drill, i-group drill, i-flat drill), i- integral cemented carbide. izinsimbi zokubhoboza, imbobo yembobo engashoni, inkomba yembobo ejulile, imbobo yokubhoboza izidleke kanye nezinsimbi zokubhola ezishintshayo.
2,Ukuphulwa kwe-chip nokususwa kwe-chip
Ukusikwa kwe-drill bit kwenziwa emgodini omncane, futhi ama-chips kufanele akhishwe nge-groove yokusika ye-drill bit, ngakho-ke ukwakheka kwe-chip kunomthelela omkhulu ekusebenzeni kokusika kwe-drill bit.Ama-chip shapes ajwayelekile afaka ama-flake chips, ama-tubular chips, ama-chips enaliti, ama-chips spiral tapered, ama-ribbon chips, ama-chips amise okwefeni, ama-powdery chips, njll.
Isihluthulelo sokumba - ukulawulwa kwe-chip
Lapho umumo we-chip ungafaneleki, izinkinga ezilandelayo zizokwenzeka:
①Ama-chips amahle avimba i-odge groove, athinta ukunemba kokumba, anciphisa impilo ye-drill bit, futhi aphule ngisho ne-drill bit (njengama-powdery chips, ama-chips amise okwefeni, njll.).
②Ama-chips amade azungeze i-drill bit, avimbe ukusebenza, abangele umonakalo ku-drill bit noma avimbele ukusika uketshezi ukuthi lungangeni embobeni (njengama-spiral chips, ama-ribbon chips, njll.).
Indlela yokuxazulula inkinga ye-chip shape engalungile:
①Umphumela wokuphulwa kwe-chip nokususwa kwe-chip ungathuthukiswa ngokukhuphula izinga lokuphakelayo, ukudla okuphakelayo ngezikhathi ezithile, ukugaya i-cross edge, ukufaka i-chip breaker, njll., ngokulandelanayo noma ngokuhlanganyela, ukuze kuqedwe izinkinga ezibangelwa ama-chips.
②Umshini wokubhoboza i-chip ochwepheshe ungasetshenziselwa ukubhola.Isibonelo, unqenqema oluklanyelwe ukuphulwa kwe-chip lwengezwa ku-groove ye-drill bit ukuze kuphuke ama-chips abe ama-chips asulwe kalula.Imfucumfucu izolahlwa kahle eduze komsele ngaphandle kokuvaleka emseleni.Ngakho-ke, umshini omusha wokubhoboza i-chip uzuza umphumela wokusika obushelelezi kunomshini ovamile.
Ngesikhathi esifanayo, insimbi emfushane ye-scrap yenza kube lula ukuthi into epholile igeleze endaweni yokubhoboza, ithuthukise nakakhulu umphumela wokulahla ukushisa nokusebenza kokusika ngesikhathi sokucubungula.Ngaphezu kwalokho, ngenxa yokuthi unqenqema olusanda kufakwa lokuphulwa kwe-chip lungene kuwo wonke umsele we-drill bit, ukwakheka kwawo nokusebenza kwawo kusengagcinwa ngemva kwezikhathi ezimbalwa zokugaya.Ngaphezu kokuthuthukiswa komsebenzi okungenhla, kufanelekile ukusho ukuthi umklamo uqinisa ukuqina komzimba wokubhoboza futhi ukhuphule kakhulu inani lemigodi eboshiwe ngaphambi kokugaya okukodwa.
3,Ukunemba kokumba
Ukunemba kwembobo ikakhulukazi kwakhiwe izici ezifana nosayizi wembobo, ukunemba kwendawo, i-coaxiality, ukuzungeza, ukukhahlamezeka kwendawo kanye ne-hole burr.
Izinto ezithinta ukunemba komgodi ozokwenziwa ngomshini ngesikhathi sokumba:
①Ukunemba kokugoqa kanye nezimo zokusika ze-drill, njengesibambi samathuluzi, isivinini sokusika, izinga lokuphakelayo, uketshezi lokusika, njll.
