Ukuqhuba yindlela yokuqhubekisa eyona mveliso. Xa kuthengwa i-bits ye-bill, i-bits yedrill ivela ngezinto ezahlukeneyo kunye nemibala eyahlukeneyo. Ke imibala eyahlukeneyo ye-bits inceda njani? Ngaba umbala unento yokwenza nomgangatho we-Drill? Nguwuphi umbala we-farll kungcono ukuthenga?
Okokuqala, kufuneka senze icace into yokuba umgangatho we-drill bit ayinakugwetywa nje ngombala wayo. Akukho luhlobo ngqo nongenakuthelekiswa nanto phakathi kombala kunye nomgangatho. Imibala eyahlukeneyo ye-bill yebill ikakhulu ibangelwa ziindlela ezahlukeneyo zokusebenza. Ewe kunjalo, sinokwenza umgwebo oqinileyo usekwe kumbala, kodwa ii-bits ze-bits eziphantsi zomgangatho ophantsi kakhulu ziya kuqhuba imibala yazo ukufezekisa imbonakalo yemigangatho ephezulu kakhulu.
Ke yintoni umahluko phakathi kwe-bits yemibala eyahlukeneyo?
Umgangatho ophezulu osemgangathweni wensimbi yentsimbi ephezulu yentsimbi ihlala ifumaneka kumhlophe. Ewe kunjalo, i-drill eqengqelekayo inokuthi ibe cwaka ngokugaya isangqa esingaphandle. Yintoni ebangela ukuba babe nomgangatho ophezulu asiyonto kuphela yezinto ngokwawo, kodwa kunye nolawulo oluphambili ngexesha lokugaya. Kungqongqo kakhulu kwaye akuyi kubakho sitshisi esixhobo. Abamnyama bangamabhongo e-bit. Yindlela yekhemikhali ebeka isixhobo esigqityiweyo kumxube we-ammonia kunye ne-vapor yamanzi kwaye yenza unyango lokugcina ubushushu nge-540 ~ 560c ° Ukuphucula ukuqina kwesixhobo. Uninzi lwezinto ezimnyama ze-Drill okwangoku kwimarike zimnyama kuphela ngombala (ukwenzela ukugubungela ukutshisa okanye ulusu olumnyama ngaphezulu kwesixhobo), kodwa eyona mpembelelo isetyenzisiweyo ayikhange iphuculwe ngokufanelekileyo.
Kukho iinkqubo ezi-3 zokuvelisa iibits. Ukuntywila okumnyama yeyona nto imbi kakhulu. Abamhlophe baneemiphetho ezicacileyo nezemizila. Ukusukela ukusukela kwiqondo lokugcina i-oxidotion eliphezulu alifuneki, ubume beenkozo zentsimbi akuyi kutshatyalaliswa, inokusetyenziselwa ukuqhuba nzima ngobunzima kancinci. I-bill etyheli-brown ephuzi ye-bits iqulethe i-cobabalt, enguMgaqo ongacacanga kumzi mveliso we-Drill. Idayimani equlathe i-Cobabayidi yaqala kwasekuqaleni, kodwa kamva ifakwe kwi-tyheli-brown (eyaziwa ngokuba ngu-Amber). Zizo ezinye zezona zinto zijikelezayo. I-M35 (Co 5%) ikwanombala wegolide obizwa ngokuba yiTitanium-ebiwe, eyahlulahlulwe yangumboniso wokuhombisa kunye noqoqosho. Ukubekwa kwembeko akulunganga, ijongeka intle. Iziphumo zokufaka i-electropreation ihle kakhulu. Ubunzima bunokufikelela kwi-HRC78, ephakame ngaphezu kobunzima be-cobalt drill (HRC54 °).
Ungayikhetha njani i-drill bit
Kuba umbala ayisiyo ikhrayitheriya yokugweba umgangatho we-drill bit, indlela yokukhetha i-drill bit?
Ukusuka kumava, okuthetha ngokubanzi, ii-bits ezimhlophe ze-Drill zihlala ziyintsimbi ephakamileyo yentsimbi kwaye kufanele ukuba ibe nomgangatho owona mgangatho. Ezi zegolide zine-titanium ye-titanium kwaye zihlala zezona zilungileyo okanye ezona zimbi kwaye zinokukhohlisa abantu. Umgangatho wokugxeka naye uyahluka. Abanye basebenzisa isixhobo se-carbon esemgangathweni esemgangathweni, ekulula ukuyifumana kwaye irhwitshi, ngoko ke kufuneka ityhafile.
Kukho uphawu lwentengiso kunye ne-diameter demares kwi-shank ye-Drill bill, ehlala icace, kwaye umgangatho we-laser kunye ne-elecking akufuneki kube kubi kakhulu. Ukuba abalinganiswa ababunjiweyo banemiphetho ye-convex, ibonisa ukuba i-Drill incinci ilungelelene, ngenxa yokuba ulwandlalo lwabalinganiswa luza kubangela ukuchaneka kwe-bill bit ukusilela ukufezekisa iimfuno. Umphetho wegama uqhagamshelwe kakuhle kumhlaba wokusebenza we-cylindrical of cedpiece, kwaye i-drill bit kunye nomda ocacileyo wegama usemgangathweni olungileyo. Kuya kufuneka ukhangele i-rill bit kunye nomphetho ofanelekileyo osikelweyo kwincam. I-drives epheleleyo yomhlaba inesikithi esihle kakhulu kwaye ifezekise iimfuno zomhlaba we-helix, ngelixa i-drills yomgangatho ophosakeleyo inomphezulu ophantsi.
