Insimbi engagqwali equkethe i-cobalttwist drillingenye yemishini yokusonta, eqanjwe nge-cobalt equkethwe ezintweni zayo.Insimbi engagqwali ene-cobalttwist drillsasetshenziswa kakhulu ukucubungula insimbi engagqwali.Uma kuqhathaniswa nezinsimbi ezisontekile zensimbi ezinesivinini esikhulu, zinokuqina okuphezulu nokunemba okuphezulu.
I-cobalt equkethetwist drillsziqukethe isakhi samakhemikhali i-cobalt Co. Inhloso yokwengeza i-cobalt ezintweni ezingavuthiwe ze-drill bit ukuthuthukisa ukumelana nokushisa okuphezulu kanye nokumelana nokugaya kwe-drill bit, ukuze ukubhola kufinyelele injongo yakho.Ngokuvamile ihlukaniswe ngezinhlobo ezimbili I-cobalt ene-cobalt ne-high-cobalt, kunezinhlobo ezimbili zezinto zokwakha: i-M35 ne-M42.Izinsimbi zokubhoboza i-cobalt ziqinile kunezinsimbi ezisontekile ezisontekile, kodwa futhi zintekenteke.Insimbi ye-Tungsten ishwabene kakhulu, kodwa inokuqina okubomvu okuphezulu: nakuba insimbi ene-cobalt ingagugi futhi inokuqina okuhle, ubulukhuni bayo obubomvu bubuthakathaka. babe nezabo izinzuzo.Indlela yokukhetha i-drill bit incike ekukhethweni kwejubane lokusika nokujula kokusika.
Ngokuvamile, ngokuvamile isetshenziselwa ukucubungula imikhiqizo yensimbi engagqwali, ithusi, ne-aluminium.Le mikhiqizo inamandla amakhulu, ngakho-ke ine-plasticity empofu.Ngesikhathi sokumba lezi zinto, amanzi akhishiwe ahlanganiswei-drill bit.Ukuze kuxazululwe le nkinga, izizukulwane ezizayo ziye zasungula imishini yokuzivocavoca equkethe i-cobalt, ukubhola kweqembu nokunye.Kufana nezandla ezimbili ezibambene ziqine.Uma kufanele uyidonse kanzima, kufanele uyibophe futhi uyigaye njalo endaweni yokuhlukanisa.Ngale ndlela, izinga lokushisa eliphezulu liyakhiqizwa.Lapho i-drill bit ejwayelekile ihlangabezana nokushisa okuphezulu, ikhula ngokushesha, futhi i-torque eqhubekayo isetshenziswa. nge-drill shank idala ukuthi i-drill bit yona iphuke, noma ichopho lokubhoboza lingakwazi ukusetshenziswa.Ngomusho olula, umshini wokubhoboza oqukethe i-cobalt uwukubhoboza okusontekile okune-cobalt okwengeza isakhi samakhemikhali i-cobalt futhi kuyasetshenziswa. ukusika nokugaya izinsimbi ezisezingeni eliphezulu ezijwayele ukuba nezinsimbi ezisezingeni eliphezulu.
Indlela yokulola
"Ukugaya kancane" okokuqala futhi okuyinhloko "akukho ukugaya".Uma uthola i-drill bit bese uyigaya ngokushesha, kufanele kube ukugaya ngokungaboni.Kuphela ngokubeka indawo kahle ngaphambi kokulola isisekelo singabekwa isinyathelo esilandelayo "sokulola".Lesi sinyathelo sibaluleke kakhulu.Amafomula amane asetshenziswa lapha ukuqondisa inqubo yokulola, futhi umphumela uba ngcono.
Ifomula yokuqala: “Unqenqema lulinganiselwe futhi isondo lincike kulo.” Lesi isinyathelo sokuqala sokuma okuhlobene kwei-drill bitkanye nesondo lokugaya.Ngokuvamile, abafundi bancika esondweni lokugaya futhi baqale ukulola ngaphambi kokuba bazinze onqenqemeni.Lokhu kumelwe kube nzima ukugaya. “Unqenqema” lapha luwumkhawulo wokusika, futhi “ukulinganisa” kusho ukuthi unqenqema oluyinhloko lwengxenye ecijile. isendaweni evundlile.“Indawo yesondo” isho indawo engaphezulu yesondo lokugaya."Ukuncika" kusho ukusondela kancane.Kulesi sikhathi, i-drill bit ayikwazi ukuthinta isondo lokugaya.
Ifomula yesibili: “I-drill shaft idedela i-engeli engaphambili ngokudayelayo.” Lokhu kubhekisela ebudlelwaneni bendawo phakathi komugqa we-eksisi webhithi yokubhoboza kanye nongaphezulu kwesondo lokugaya. "I-engeli yangaphambili" iyingxenye ye-engeli ephezulu engu-118°. ±2o, okungaba ngu-60°.Lesi sikhundla sibaluleke kakhulu, esithinta ngokuqondile usayizi we-engeli ephezulu ye-drill bit, umumo we-engeli eyinhloko yokusika kanye ne-engeli ye-bevel yonqenqema oluvundlile.Abafundi kufanele batshelwe ukuthi bakhumbule i-engeli engu-60° ngendlela evamile. kusetshenziswe ibhodi elingunxantathu elingu-30°, 60°, kanye no-90°, okulula kubafundi ukulazi kahle.Ifomula Yokuqala kanye nefomula yesibili womabili abhekisela ekumeni okuhlobene kwebhithi lokubhoboza ngaphambi kokulola.Zombili kufanele zihlanganiswe futhi zilinganise.Ungayizibi i-engeli ye-bevel ukuze ushelele unqenqema, noma uzibe i-engeli ye-bevel ukuze wenze bushelelezi i-oblique axis.Emsebenzini wangempela, lawa maphutha avame kakhulu.Kulesi sikhathi, i-drill bit ilungele ukuxhumana isondo lokugaya elinendawo efanele.
Ifomula yesithathu: "Lola ingemuva ukusuka ku-blade ukuya ngemuva."Lapha isho ukulola kancane kancane kuyo yonke indawo engemuva kusukela onqenqemeni lwe-drill bit.Lokhu kusiza ukuqeda ukushisa nokulola.Ngesisekelo sokuzinzisa nokuhlanganisa. amafomula okukodwa nakwesibili, i-drill bit ingathinta kancane isondo lokugaya ngalesi sikhathi ngenani elincane lokulola.Lapho ulola, qaphela ukufana kwezinhlansi, lungisa ukucindezela ngesikhathi, futhi unake ukupholisa kwe-drill bit. Lapho ukulola kuqalwa kabusha ngemva kokupholisa, kuyadingeka ukuqhubeka ukusetha indawo yefomula yokuqala kanye neyesibili. Lokhu ngokuvamile akulula ukukwazi kahle ekuqaleni, futhi ukulunga kwendawo yakho ngokuvamile kushintshwa ngokuzenzakalelayo.
Ifomula yesine: "Swikela phezulu naphansi, ungatshekisi umsila wakho."Lesi senzo sibaluleke kakhulu enqubweni yokulola i-drill bit. Ngokuvamile, abafundi baphendulela "ukushwibeka phezulu naphansi" kube "ukuguqula phezulu naphansi" phakathi ukulola, okubangela ukuthi elinye i-blade eliyinhloko le-drill bit libhujiswe.Ngasikhathi sinye, umsila we-drill bit akufanele utshekiswe phezulu ngaphezu komugqa ovundlile wesondo lokugaya, ngaphandle kwalokho unqenqema luyoba buthuntu futhi alunakunqunywa. .
