Drill izingcezuzivame ukusetshenziswa ezimbonini zokumba izicelo ukudala izimbobo cylindrical ezintweni ezihlukahlukene ezifana metal, ukhuni, futhi plastic.Aqukethe unqenqema lokuphotha oluxhunywe ku-shaft oshayelwa umshini wokumba.Izingcezu zokumba zisetshenziswa kakhulu ezinhlobonhlobo zezimboni, kusukela kwezimbiwayo nezokwakha kuye ekuhloleni uwoyela negesi.
Kunezinhlobo eziningi zama-drill bits atholakalayo, ngayinye yakhelwe izinto ezithile kanye nezidingo zohlelo lokusebenza.Ezinye zezinhlobo ezivame kakhulu zihlanganisa ama-twist drill, ama-spade bits, nama-auger bits.Ama-twist drillsasetshenziselwa ukubhoboza insimbi, kuyilapho ama-spade nama-auger bits adumile emsebenzini wokhuni.Ezinye izinhlobo zama-drill bits zihlanganisa amasaha embobo, ama-drill, ama-countersinks, nama-reamers.
Enye yezindlela ezibaluleke kakhulu zokukhetha i-drill bit ukwakheka kwayo kwempahla.Izinto ezisetshenziswayo ezihlukene zinamazinga ahlukene obulukhuni, ukuhuga, nokumelana nokushisa, konke okungaba nomthelela omkhulu ekusebenzeni kahle nempilo ye-drill bit.Ezinye zezinto ezisetshenziswa kakhulu ekubholeni zifaka insimbi enesivinini esikhulu, insimbi ye-cobalt, i-carbide, nedayimane.
Ubude besikhathi sokubhoboza ibhilidi buwukucatshangelwa okubalulekile ezinhlelweni zokumba izimboni.Phela, ama-drill bits anesikhathi esifushane sokuphila adala isikhathi esibalulekile sokuphumula kanye nezindleko zokulungisa.Ukungqubuzana nokushisa okukhiqizwa phakathi nokubhoboza kungabangela ukuguga okuphawulekayo onqenqemeni lwebhithi, okuholela ekunciphiseni ukusebenza kahle nokwehluleka ekugcineni.Ukwandisa isikhathi sokuphila se-drill bit, ama-coatings ahlukahlukene nokwelashwa kungasetshenziswa, njenge-titanium nitride noma ama-carbon-coatings afana nedayimane.
Embonini yezimayini,ukubhoboza izingcezuzibalulekile ekuhloleni, ekumbiweni nasekukhishweni kwamaminerali.Izingcezu zokubhoboza eziklanyelwe ukumelana nemvelo enzima engaphansi komhlaba kufanele zibhoboze amadwala nomhlabathi ngempumelelo.Amaloli amakhulu ahlome ngemishini yokumba ethuthukisiwe enza kube lula ukumbiwa kwamaminerali ngokuqoqa idatha yokwakheka komhlaba nokumba ezindaweni ezinembile.
Ekuhloleni uwoyela negesi, ukumba okuqondisayo kuyindlela evamile esetshenziselwa ukukhipha izinsiza endaweni engaphansi.Izingcezu zokubhoboza eziqondisayo ziklanyelwe ukuhamba zivundlile futhi ziqonde ngesikhathi sokumba, okuvumela ukufinyelela emaphaketheni amaningi ezisetshenziswa ezivela emthonjeni owodwa.Le nqubo inciphise kakhulu izindleko kanye nesikhathi sokufinyelela endaweni yokugcina uwoyela negesi.
Imboni ye-aerospace nayo izuze kakhulu ekuthuthukisweni kobuchwepheshe be-drill bit.Isibonelo, ama-drill bits asetshenziselwe ukubhoboza izindonga eziwugqinsi ze-titanium zezinjini ze-jet noma izinto ze-carbon fiber ezingasindi ezisetshenziswa ekwakhiweni kwezindiza zesimanje.Ngokukhula kwesidingo sezindiza ezinkulu nokuhlolwa komkhathi, ngokungangabazeki kuzovela ubuchwepheshe bokumba obuthuthuke kakhulu.
Ekuphetheni,ukubhoboza izingcezu ziwumgogodla wokumba izimboni, futhi intuthuko yabo ithuthukise kakhulu ukusebenza kahle kanye nokuphumelela kwezindleko zokumbiwa kwezinsiza.Ngokuqhubeka nokuthuthukiswa kwezinto, okokunamathela, nokwelashwa, izinsimbi zokubhoboza zizoqina nakakhulu futhi zihlale isikhathi eside.Ngokuzayo, ubuchwepheshe bokumba obuthuthuke kakhulu buzovela njengoba izimboni ziqhubeka nokufuna izindlela ezintsha nezintsha zokufinyelela izinsiza ezibalulekile.
