Amasuntswana okugayaziqhele ukusetyenziswa kwizicelo zokomba kwimizi-mveliso ukwenza imingxuma cylindrical kwizinto ezahlukeneyo ezifana nentsimbi, iinkuni, kunye neplastiki.Ziquka i-spinning cut edge edityaniswe kwishafti eqhutywa ngumatshini wokomba.Iingceba zokumba zisetyenziswa ngokubanzi kuluhlu olubanzi lwemizi-mveliso, ukusuka kwimigodi nokwakhiwa ukuya kuphononongo lwe-oyile negesi.
Kukho iintlobo ezininzi ze-drill bits ezikhoyo, nganye yenzelwe izinto ezithile kunye neemfuno zesicelo.Ezinye zezona ntlobo zixhaphakileyo ziquka ii-twist drills, iibits ze-spade, kunye ne-auger bits.Twist drillszisetyenziselwa ukugrumba zibe yintsimbi, lo gama umhlakulo kunye ne-auger bits zithandwa kumsebenzi womthi.Ezinye iintlobo ze-drill bits ziquka isarha yomngxuma, i-drill drill, i-countersinks, kunye ne-reamers.
Enye yezona ndlela zibalulekileyo zokukhetha i-drill bit kukwakheka kwayo.Izixhobo ezahlukeneyo zinemigangatho eyahlukeneyo yobulukhuni, ukuqina, kunye nokumelana nobushushu, zonke ezinokuthi zibe nefuthe elibonakalayo ekusebenzeni kakuhle kunye nobomi be-drill bit.Ezinye zezona zinto zixhaphakileyo zisetyenziswa kwi-drill bits ziquka intsimbi enesantya esiphezulu, intsimbi ye-cobalt, i-carbide kunye nedayimane.
Ubomi obude be-drill bit yingqwalasela ebalulekileyo kwizicelo zokomba kwimizi-mveliso.Emva kwayo yonke loo nto, ii-drill bits ezinobomi obufutshane zidala ixesha elibalulekileyo kunye neendleko zokugcina.I-friction kunye nobushushu obuveliswa ngexesha lokomba kunokubangela ukuguga okubalulekileyo kunye nokukrazula kumda wokusika, okukhokelela ekunciphiseni ukusebenza kakuhle kunye nokusilela ekugqibeleni.Ukwandisa ixesha lokuphila kwi-drill bit, ii-coatings ezahlukeneyo kunye nonyango lunokusetyenziswa, njenge-titanium nitride okanye i-diamond-like-carbon coatings.
Kwishishini lezemigodi,i-drill bitszibalulekile kuphononongo, ukugrumba, kunye nokutsalwa kwezimbiwa.Imingxuma yokubhola eyilelwe ukumelana nemekobume erhabaxa yangaphantsi komhlaba kufuneka igqobhoze amatye nomhlaba ngokufanelekileyo.Iilori ezinkulu ezixhotyiswe ngezixhobo zokomba eziphambili ziququzelela ukutsalwa kwezimbiwa ngokuqokelela idatha yokwakheka komhlaba kunye nokugrumba kwiindawo ezichanekileyo.
Ekuhlolisisweni kweoli kunye negesi, i-direct drilling yindlela eqhelekileyo esetyenziselwa ukukhupha izibonelelo ukusuka kwindawo engaphantsi.Amasuntswana okomba oMkhombandlela ayilelwe ukuba ahambe ngokuthe tye nathe nkqo ngexesha lokomba, okuvumela ukufikelela kwiipokotho ezininzi zemithombo evela kumthombo omnye.Obu buchule bunciphise kakhulu iindleko kunye nexesha lokufikelela koovimba beoyile negesi.
Umzi-mveliso we-aerospace nawo uzuze kakhulu kwinkqubela phambili yetekhnoloji ye-drill bit.Umzekelo, amasuntswana okomba asetyenziselwe ukugqobhoza kwiindonga ezishinyeneyo ze-titanium zeenjini zejethi okanye izixhobo ezikhaphukhaphu zekhabhoni zefiber ezisetyenziswa kulwakhiwo lweenqwelomoya zale mihla.Ngokunyuka kwemfuno yeenqwelomoya ezinkulu kunye nokuphononongwa kwendawo, itekhnoloji yokomba ephucukileyo ngokungathandabuzekiyo iya kuvela.
Ukuququmbela,i-drill bits zingumqolo wokugrumba kwimizi-mveliso, kwaye ukuqhubela phambili kwabo kuphucule ngokubonakalayo ukusebenza kakuhle kunye nokuphumelela kweendleko zokumbiwa kwezixhobo.Ngophuhliso oluqhubekayo lwemathiriyeli, iingubo, kunye nonyango, i-drill bits iya kuba namandla ngakumbi kwaye ihlala ixesha elide.Kwixesha elizayo, ubugcisa bokugrumba obuphezulu buya kuvela njengoko amashishini eqhubeka efuna iindlela ezintsha nezintsha zokufikelela kwizixhobo ezibalulekileyo.
