Xa kufikwa ekubholeni izinto eziqinileyo ezifana nesinyithi, ukukhetha i-drill bit efanelekileyo kubalulekile. Kukho iintlobo ngeentlobo zee-drill bits ezenzelwe ngokukodwa ukubhoboza ngesinyithi, kuquka ii-drill bits ezigqunywe nge-tin kunye nee-titanium nitride drill bits.
Iibhithi zokubhola ezigqunywe ngetin, ezaziwa ngokuba ziibhithi zokubhola ezigqunywe ngetin, ziyindlela ethandwayo yokubhola ngentsimbi. Ezi bhithi zokubhola zigqunywe ngomaleko omncinci wetin, nto leyo enceda ekunciphiseni ukungqubana nobushushu ngexesha lenkqubo yokubhola. Olu gquma lukwabonelela ngokhuseleko olongezelelweyo ekungcoleni, nto leyo eyenza ukuba iibhithi zokubhola ezigqunywe ngetin zibe lukhetho oluhlala ixesha elide noluhlala ixesha elide lokubhola ngentsimbi.
Enye yezona nzuzo ziphambili zeebhithi zokubhola ezigqunywe ngetin kukuba zikwazi ukuhlala zibukhali ixesha elide. Ukugqunywa kwetin kunceda ukuthintela ukuba ibhithi yokubhola ingakhawulezi, nto leyo evumela ukugqobhoza okusebenzayo nokuchanekileyo. Ukongeza, ukungqubana okuncitshisiweyo okubonelelwa kukugqobhoza kwetin kunceda ukunciphisa ukwakheka kobushushu, nto leyo eluncedo ngakumbi xa kugqobhozwa kwiintsimbi eziqinileyo.
Enye into esetyenziswa kakhulu ekubholeni isinyithi yi-titanium nitride drill bit. Ezi drill bits zigqunywe ngomaleko we-titanium nitride, into eqinileyo yeseramikhi enika ukumelana nokuguguleka okuhle kunye nokutshatyalaliswa kobushushu. I-titanium nitride coating ikwanika i-drill bit imbonakalo yegolide, okwenza kube lula ukuyibona phakathi kwezinye iintlobo zee-drill bits.
Enye yezona nzuzo ziphambili zeebhithi zokubhola ze-titanium nitride bubulukhuni bazo obungaqhelekanga, obuzivumela ukuba zihlale zibukhali nokuba zigqobhoza kwiintsimbi ezinzima. Oku kuzenza zibe lukhetho oluhle kakhulu kwizicelo zokubhola zesinyithi ezinzima apho ukuqina kunye nobomi obude bubaluleke kakhulu. Ukongeza, ukumelana nobushushu obubonelelwa yi-titanium nitride coating kunceda ukwandisa ubomi bebhithi yokubhola, okwenza kube lukhetho oluthembekileyo kwimisebenzi yokubhola enzima.
Kukho izinto ezibalulekileyo ekufuneka uziqwalasele xa ukhetha i-metal drill bit efanelekileyo kwiimfuno zakho ezithile. Uhlobo lwesinyithi osigqobhozayo, ubukhulu bezinto ezisetyenzisiweyo, kunye nendlela osigqobhoza ngayo zonke ezi zinto ziya kudlala indima ekumiseleni i-drill bit efanelekileyo kulo msebenzi. Ezi ngcebiso zilandelayo zinokukunceda ukhethe i-metal drill bit efanelekileyo:
1. Cinga ngohlobo lwesinyithi: Iintsimbi ezahlukeneyo zinobunzima obahlukeneyo, ngoko ke kubalulekile ukukhetha i-drill bit eyenzelwe ngokukodwa uhlobo lwesinyithi osigqobhozayo. Umzekelo, iintsimbi ezithambileyo ezifana ne-aluminium zinokufuna uhlobo olwahlukileyo lwe-drill bit xa kuthelekiswa neentsimbi eziqinileyo ezifana nentsimbi okanye intsimbi engatyiwayo.
2. Vavanya uphahla: Iibhithi zokubhola ezifakwe kwi-tin kunye neebhithi zokubhola ze-titanium nitride zibonelela ngeenzuzo ezahlukeneyo ngokubhekiselele ekungagugini, ukusasazwa kobushushu, kunye nokumelana nokugqwala. Cinga ngeenzuzo ezithile zophahla ngalunye kwaye ukhethe oluhlangabezana kakuhle neemfuno zakho zokubhola.
3. Misela ubungakanani bebhithi yokubhola: Ubungakanani bebhithi yokubhola bubalulekile ekufezekiseni iziphumo zokubhola ezichanekileyo nezichanekileyo. Qiniseka ukuba ukhetha ubungakanani bebhithi yokubhola ehambelana nobubanzi bomngxuma ekufuneka uwubhoboze, ngelixa ucinga ngobukhulu bezinto zesinyithi.
4. Vavanya ukusetyenziswa kokugrumba: Nokuba ugrumba umngxuma wokuhlola, udala umngxuma omkhulu, okanye ugrumba ngokuchanekileyo, ukusetyenziswa kokugrumba okuthile kuya kuchaphazela uhlobo lwe-drill bit omele uyisebenzise. Ezinye ii-drill bit zenzelwe ukugrumba ngokubanzi, ngelixa ezinye zenzelwe imisebenzi ethile.
Ukongeza kuhlobo lwesixhobo sokubhola ngesinyithi, kubalulekile ukusebenzisa indlela efanelekileyo yokubhola ukuze ufumane iziphumo ezilungileyo. Nazi ezinye iingcebiso ngokubanzi zokubhola ngesinyithi ngokuchanekileyo nangokufanelekileyo:
1. Sebenzisa i-center punch: Ngaphambi kokuba ubhoboze, sebenzisa i-center punch ukwenza i-inbot encinci kumphezulu wesinyithi. Oku kuya kunceda ukukhokela i-drill bit kwaye kuthintele ukuba ingatyibiliki xa uqala ukubhoboza.
2. Qala nge-drill bit encinci: Xa ugqobhoza isinyithi, kudla ngokuba ngcono ukuqala nge-drill bit encinci ukuze wenze umngxuma wokuhlola. Oku kunceda ukuqinisekisa ukuchaneka okukhulu kwaye kuthintele i-drill bit enkulu ukuba ingaphumi endleleni.
3. Faka ulwelo lokusika: Kwiintsimbi eziqinileyo, ezifana nentsimbi engagqwaliyo okanye intsimbi eqinileyo, ukufaka ulwelo lokusika kwindawo yokugrumba kunokunceda ukunciphisa ubushushu kunye nokungqubana, kwandise ubomi bento yokugrumba kwaye kwandise ukusebenza kakuhle kokugrumba.
4. Sebenzisa isantya sokubhola esifanelekileyo: Iintsimbi ezahlukeneyo zifuna isantya esahlukileyo sokubhola ukuze kufumaneke iziphumo ezilungileyo. Nceda uqhagamshelane nomenzi ukuze ufumane iingcebiso malunga nesixhobo sokubhola esithile kunye nezinto zesinyithi osisebenzisayo.
Ngokukhetha isixhobo sokubhola sesinyithi esifanelekileyo kunye nokusebenzisa iindlela ezifanelekileyo zokubhola, ungafumana iziphumo ezichanekileyo nezisebenzayo xa usenza iintsimbi.
