I-Cobalt equlethe intsimbi engatyiwayotwist drillyenye yeendlela zokujija, ezithiywe nge-cobalt equlethwe kwizinto zayo. I-Cobalt-equlathe intsimbi engatyiwayotwist drillsubukhulu becala zisetyenziselwa ukusetyenzwa kwentsimbi engatyiwayo.Xa kuthelekiswa needrill zentsimbi ezinesantya esiphezulu ezijijwayo, zinobunzima obuphezulu kunye nokuchaneka okuphezulu.
Cobalt-equlathetwist drillsziqulathe imichiza element cobalt Co. Injongo yokongeza i-cobalt kwizinto ezikrwada ze-drill bit kukuphucula ukumelana nobushushu obuphezulu kunye nokumelana nokusila kwe-drill bit, ukuze u-drilling ufezekise injongo yayo. Ngokubanzi yahlulwe ibe ziindidi ezimbini I-cobalt ene-cobalt kunye ne-high-cobalt, kukho iintlobo ezimbini zezinto eziphathekayo: i-M35 kunye ne-M42.I-Cobalt drill bits inzima kunezoqheliso eziqhelekileyo, kodwa zibuthathaka. Intsimbi yeTungsten ilukhuni ngakumbi, kodwa inobulukhuni obubomvu obuphezulu: nangona intsimbi ene-cobalt ingagugi kwaye inobulukhuni obuhle, ubulukhuni bayo obubomvu bumbi. banezabo iingenelo.Indlela yokukhetha i-drill bit kuxhomekeke ekukhethweni kwesantya sokusika kunye nokusika ubunzulu.
Enyanisweni, ngokuqhelekileyo isetyenziselwa ukucubungula insimbi engenasici, ubhedu, kunye neemveliso ze-aluminium.Ezi mveliso zinamandla amakhulu, ngoko zineplastiki ehluphekileyo.Ngexesha lenkqubo yokugaya ezi zixhobo, amanzi akhutshiweyo afakwe kwi-plasticity.drill bit.Ukuze kusonjululwe le ngxaki, izizukulwana ezizayo ziye zaqulunqa i-cobalt-containing drills, i-drills yeqela kunye nokunye.Kufana nezandla ezibini ezibambene ngokuqinileyo.Ukuba kufuneka uyitsale nzima, kufuneka uyibophe kwaye uyicole rhoqo kwindawo yokwahlukana.Ngale ndlela, ubushushu obuphezulu buyenziwa.Xa i-drill bitana idibana nobushushu obuphezulu, iyanda ngokukhawuleza, kwaye i-torque eqhubekayo isetyenziswa. nge-drill shank ibangela ukuba i-drill bit ngokwayo iphuke, okanye incam ye-drill ayikwazi ukusetyenziswa.Kwisivakalisi esilula, i-cobalt-containing drill yi-cobalt-containing twist drill eyongeza i-chemical element cobalt kwaye isetyenziswe. ukusika kunye nokusila iintsimbi ezinobushushu obuphezulu obuthambekele kwiintsimbi ezinobushushu obuphezulu.
Indlela yokulola
"Ukugaya okuncinci" kuqala kwaye "akukho kugaya".Ukuba ufumana i-drill bit kwaye uyigaye ngokukhawuleza, kufuneka ibe yimpumputhe yokugaya.Kuphela ngokubeka indawo kakuhle ngaphambi kokulola isiseko sinokubekwa kwisinyathelo esilandelayo "sokulola".Eli nyathelo libaluleke kakhulu.Iifomula ezine zisetyenziselwa apha ukukhokela inkqubo yokulola, kwaye umphumo ungcono.
Ifomula yokuqala: “Umphetho ulinganisiwe kwaye ivili loyame ngalo.” Eli linyathelo lokuqala kwindawo ehambelanayodrill bitkunye nevili lokusila.Ngokuqhelekileyo, abafundi baxhomekeke kwivili lokusila kwaye baqale ukulola ngaphambi kokuba bazinze umda. ikwindawo ethe tye.“Umphezulu wevili” ubhekisa kumphezulu wevili lokusila."Ukubhitya" kuthetha ukusondela ngokucothayo.Ngeli xesha, intwana yokubhola ayinakuchukumisa ivili lokusila.
Ifomula yesibini: “I-drill shaft ikhupha i-engile yangaphambili ngokudayayo.” Oku kubhekiselele kubudlelwane bendawo phakathi komgca we-axis wesuntswana lokubhola kunye nomphezulu wevili lokusila. ±2o, malunga ne-60 °.Esi sikhundla sibaluleke kakhulu, esichaphazela ngokuthe ngqo ubungakanani be-angle ephezulu ye-drill bit, imilo yecala eliphambili lokusika kunye ne-angle ye-bevel ye-edge edge.Abafundi kufuneka bakhuthazwe ukuba bakhumbule i-angle ye-60 ° ngokuqhelekileyo. isetyenziswe 30°, 60°, kunye 90° ibhodi unxantathu, nto leyo kulula ukuba abafundi master.Ifomula One kunye nefomula ezimbini zombini zibhekisa kwindawo enxulumeneyo ye-drill bit phambi kokulola.Ezi zimbini kufuneka zidityaniswe kwaye zilinganiswe.Ungayihoyi i-engile ye-bevel ukuze ugudise umda, okanye ungayihoyi i-engile ye-bevel ukuze ugudise i-oblique axis.Kwinyani yokusebenza, ezi mpazamo zihlala zixhaphake kakhulu.Ngeli xesha, i-drill bit ikulungele ukuqhagamshelana ivili lokusila enendawo echanekileyo.
Ifomula yesithathu: "Lola umva ukusuka kwincakuba ukuya ngasemva."Apha ibhekisa ekuloleni okucothayo ngakuwo wonke umphezulu wencakuba yangasemva ukuqala kwincam yencakuba yokomba.Oku kunceda ukulahla ubushushu kunye nokulola.Ngokwesiseko sokuzinzisa kunye nokudibanisa. iifomyula enye kunye neyesibini, i-drill bit ingaqhagamshelana ngononophelo ivili lokugaya ngeli xesha elincinci lokulola. Xa ukulolwa kuqalwa kwakhona emva kokupholisa, kuyimfuneko ukuqhubeka nokuseta indawo yefomyula yokuqala neyesibini.Oku kaninzi akulula ukukwazi kwasekuqaleni, kwaye ukuchaneka kwendawo yayo kudla ngokutshintsha ngokuzenzekelayo.
Ifomula yesine: "Jiwubela phezulu nasezantsi, musa ukutyekisa umsila wakho." Esi senzo sikwabaluleke kakhulu kwinkqubo yokulola i-drill bit. Rhoqo, abafundi bajika "ukujinga phezulu naphantsi" ekubeni "bajike phezulu naphantsi" ngexesha. ukulola, okubangela ukuba enye i-blade ephambili ye-drill bit itshatyalaliswe.Ngexesha elifanayo, umsila we-drill bit akufanele uthambekele phezulu ngaphezu kwendawo ethe tye yevili lokusila, ngaphandle koko umgca uya kuba buthuntu kwaye awukwazi ukunqunyulwa. .
