Xa kufikwa kumba wokomba ngezinto eziqinileyo njengentsimbi, kubalulekile ukukhetha eyona drill bit. Kukho iindidi ngeendidi zamasuntswana okomba ezenzelwe ngokukodwa ukugrunjwa ngentsimbi, kubandakanywa amasuntswana okomba enziwe ngetin kunye ne-titanium nitride drill bits.
Amasuntswana okomba aqatywe ngenkcenkce, okwakwaziwa ngokuba ngamasuntswana okomba enziwe ngetinki, lukhetho oludumileyo lokugrumba ngentsimbi. Ezi zixhobo zokubhoboza ziqatywe ngomaleko obhityileyo wetoti, onceda ekunciphiseni ukukhuhlana nobushushu ngexesha lokomba. Olu tyaba lukwabonelela ngokhuseleko olongezelelweyo ekuthinjweni, ukwenza i-tin-coated drill bits ibe yinto ehlala ixesha elide kwaye ithatha ixesha elide lokukhetha isinyithi.
Olunye uncedo oluphambili lwe-tin-coated drill bits kukukwazi kwabo ukuhlala bebukhali ixesha elide. Ukugquma kwetoti kunceda ukunqanda i-drill bit ukuba ingabi buthuntu ngokukhawuleza, ivumela ukomba oluchanekileyo kunye noluchanekileyo. Ukongeza, ukukhuhlana okuncitshisiweyo okubonelelwa yinkcenkceshe yenkcenkce kunceda ukunciphisa ukwakheka kobushushu, okuluncedo ngakumbi xa kusonjwa ngeentsimbi ezinzima.
Enye into esetyenziswa ngokuqhelekileyo intsimbi yokomba yi-titanium nitride drill bit. Ezi zixhobo zokubhoboza zigqunywe ngomaleko we-titanium nitride, i-ceramic material eqinileyo enika ukuxhathisa okugqwesileyo kokunxiba kunye nokuphelisa ubushushu. I-titanium nitride yokwambathisa ikwanika i-drill bit imbonakalo yegolide, ikwenza kube lula ukuchonga phakathi kwezinye iindidi zamasuntswana okomba.
Olunye lolona ncedo luphambili lwe-titanium nitride drill bits bubunzima babo obukhethekileyo, obubavumela ukuba bahlale bebukhali naxa kugrunjwa ngeentsimbi ezinzima. Oku kubenza babe lolona khetho lubalaseleyo kwizicelo zokomba isinyithi esinzima apho ukuqina kunye nokuphila ixesha elide kubalulekile. Ukongeza, ukuxhathisa ubushushu okunikezelwa nge-titanium nitride yokwambathisa kunceda ukwandisa ubomi be-drill bit, iyenze ibe lukhetho oluthembekileyo kwimisebenzi enzima yokomba.
Kukho izinto ezininzi ezibalulekileyo ekufuneka uziqwalasele xa ukhetha i-drill yentsimbi efanelekileyo kwiimfuno zakho ezithile. Uhlobo lwentsimbi ogrumba ngayo, ubukhulu bezinto eziphathekayo, kunye nesicelo sakho sokomba esikhethekileyo siya kudlala indima ekumiseleni eyona ntwana igqwesileyo yomsebenzi. Ezi ngcebiso zilandelayo zinokukunceda ukhethe eyona drill bit yentsimbi ifanelekileyo:
1. Qwalasela uhlobo lwesinyithi: Iintsimbi ezahlukeneyo zinobunzima obuhlukeneyo, ngoko ke kubalulekile ukukhetha i-drill bit eyenzelwe ngokukodwa uhlobo lwesinyithi osibhobhozayo. Umzekelo, iintsimbi ezithambileyo ezifana ne-aluminiyam zinokufuna uhlobo olwahlukileyo lwe-drill bit xa kuthelekiswa neentsimbi ezinzima njengentsimbi okanye intsimbi engatyiwa.
2. Vavanya i-coating: I-tin-plated drill bits kunye ne-titanium nitride drill bits zibonelela ngeenzuzo ezahlukeneyo malunga nokumelana nokunxiba, ukutshatyalaliswa kobushushu, kunye nokuxhathisa ukubola. Qwalasela iingenelo ezithile zokwaleka ngalunye kwaye ukhethe eyona ihlangabezana neemfuno zakho zokomba.
3. Qinisekisa ubungakanani besuntswana le-drill: Ubungakanani bentwana yokomba ibalulekile ekuphumezeni iziphumo zokomba ezichanekileyo nezichanekileyo. Qinisekisa ukuba ukhetha i-drill bit yesayizi ehambelana nobubanzi bomngxuma ofuna ukuwubamba, ngelixa uqwalasela ubukhulu bezinto zetsimbi.
4. Vavanya usetyenziso lokomba: Nokuba usemba umngxuma olingwayo, udala indawo enkulu yokuvula, okanye ugrumba ngokuchanekileyo, usetyenziso oluthile lokomba luya kuba nefuthe kuhlobo lwentwana yokomba omawuyisebenzise. Amanye amasuntswana e-drill enzelwe ukomba wenjongo ngokubanzi, ngelixa ezinye ziyilelwe imisebenzi ethile.
Ukongeza kuhlobo lwentsimbi yentsimbi, kubalulekile ukusebenzisa ubuchule obufanelekileyo bokugaya ukufezekisa iziphumo ezilungileyo. Nanga amanye amacebiso okugrumba ngentsimbi ngokuchanekileyo nangempumelelo:
1. Sebenzisa i-punch yeziko: Ngaphambi kokugaya, sebenzisa i-punch yeziko ukwenza i-indentation encinci kwindawo yesinyithi. Oku kuya kunceda ukukhokela i-drill bit kwaye ithintele ukuba ingatyibiliki xa uqala ukugrumba.
2. Qala nge-drill bitana encinci: Xa ubhobhoza ngentsimbi, kudla ngokuba kuhle ukuqala nge-drill bit encinci ukwenza umngxuma wokulingwa. Oku kunceda ukuqinisekisa ukuchaneka okukhulu kwaye kuthintele i-drill bit enkulu ukuba ihambe endleleni.
3. Faka isicelo sokusika ulwelo: Kwizinyithi ezinzima, ezifana nensimbi engenasici okanye insimbi eqinile, ukusebenzisa i-cutting fluid kwindawo yokugaya kunokunceda ukunciphisa ubushushu kunye ne-friction, ukwandisa ubomi be-drill bit kunye nokwandisa ukusebenza kakuhle.
4. Sebenzisa isantya esifanelekileyo sokumba: Izinyithi ezahlukeneyo zifuna isantya esihlukeneyo sokumba ukuze sifezekise iziphumo ezilungileyo. Nceda udibane nomvelisi ngeengcebiso malunga nentwana ethile yokomba kunye nemathiriyeli yentsimbi oyisebenzisayo.
Ngokukhetha i-metal drill bit efanelekileyo kunye nokusebenzisa iindlela ezifanelekileyo zokugaya, unokufezekisa iziphumo ezichanekileyo kunye nezisebenzayo xa usenza iintsimbi.
