Uthotho:Kutheni ii-Drill Bits zingaphumeleli | Inqaku lesi-3
Amagama angundoqo:Umgangatho we-HSS drill bit, ubunzima be-drill bit, ubulukhuni be-drill bit, uxinano lwe-HSS, ukuhlolwa komgangatho we-drill bit, indlela yokuvavanya ii-drill bits
Abanye abathengi balinganisa iibhithi zokubhola xa bevavanya iisampulu zomthengisi omtsha. Okukhona ibhithi inzima, kokukhona intsimbi iba ngcono — okanye ngoko ke ingqiqo iyavakala.
Yinto eqondakalayo. Ubunzima bubonakala ngathi buyindlela yokubonisa izinto. Kodwa xa kufikwa kwiibhithi zokubhola ze-HSS, ubunzima sesinye sezona zibonakaliso zingathembekanga zomgangatho. Kwezinye iimeko, ibhithi yokubhola enzima ngokwenene luphawu lwemveliso ekumgangatho ophantsi.
Nantsi isizathu.
Ubuninzi be-HSS abutshintshi kakhulu phakathi kwamaBanga
I-High Speed Steel lusapho oluthile lweentsimbi zezixhobo ezichazwa zizinto zayo zokuxutywa - i-tungsten, i-molybdenum, i-chromium, i-vanadium, kwaye kwiindidi ze-cobalt, i-cobalt. Ezi zinto zongezwa ngeepesenti ezincinci ukulawula ubulukhuni, ukumelana nokuguguleka, kunye nobunzima obomvu.
Uxinano lwe-HSS kwiindidi eziqhelekileyo — i-M2, i-M35, i-M42 — luphakathi koluhlu oluncinci, malunga ne-8.1 ukuya kwi-8.3 g/cm³. I-M2 kunye ne-M35 zahlukile kumxholo we-cobalt (0% xa kuthelekiswa ne-5%), kodwa uxinano lwe-cobalt (malunga ne-8.9 g/cm³) lusondele ngokwaneleyo kwi-base steel matrix edibanisa i-5% yayo kwi-alloy itshintsha uxinano lulonke ngaphantsi kwe-0.1 g/cm³. Loo mahluko awubonakali ngesandla kwaye awunamsebenzi nokuba kukwisikali esichanekileyo.
Ngokwendlela esebenzayo: awunakusebenzisa ubunzima ukwahlula i-M2 kwi-M35, okanye i-HSS eqhelekileyo kwi-HSS ye-cobalt-grade.
Kutheni ke ezinye ii-Drill Bits zivakala zinzima?
Ukuba iibhloko ezimbini zokubhola ezinobukhulu obufanayo zivakala zahlukile kakhulu ngobunzima, ingcaciso phantse isoloko ikwi-geometry — kungekhona izinto eziphathekayo.
Ubunzima bento yokubhola bumiselwa bubungakanani bezinto eziqulethwe kuyo. Kubude nobubanzi obunikiweyo, utshintsho oluphambili kukuba ingakanani intsimbi esusiweyo ngexesha lokusila. Ijiyometri yeflute — ubunzulu nobubanzi bemijelo yehelical esikiweyo emzimbeni — ilawula ngokuthe ngqo oku. Iiflute ezinzulu nezibanzi zisusa izinto ezingakumbi. Iiflute ezingaphantsi zishiya ezingaphezulu.
Umenzi unokuvelisa iqhekeza elinzima lokugrumba ngokugaya iiflute ezingaphantsi. Iqhekeza ligcina izinto ezingundoqo ezingaphezulu, ngoko ke linobunzima obungaphezulu. Kodwa iiflute ezingaphantsi zinemiphumo: ukususwa kweetshiphusi kuba nzima ukusebenza, ukusika ukungqubana kuyanda, kwaye ubushushu buyanda ngokukhawuleza kwindawo yokusika. Kwizinto ezinzima okanye kwiindawo eziphezulu zokutya, oku kukhokelela ekugugeni ngokukhawuleza kunye nomngcipheko ophezulu wokungasebenzi kwangaphambi kwexesha.
Oku kuthetha ukuba i-drill bit enzima ayisiyo-drill bit engcono. Isenokuba yindawo apho ikona yasikwa khona ngokwejometri - kwaye umthengi uphosisa uphawu njengophawu lomgangatho.
Oko Kubonakaliswa Ngubunzima Ngokwenene
Ubunzima bubonakalisa ubungakanani bentsimbi eseleyo. Ubungakanani bulawulwa ngokusila. Umgangatho wokusila sisigqibo sokwenziwa.
Umenzi onamava ucola iiflute ngokwejiyometri echazwe sisicelo — i-DIN 338 okanye imigangatho efanayo ichaza i-engile ye-helix, ubunzulu beflute, kunye nejiyometri yenqaku ngesizathu. Ezi milinganiselo zilungiselelwe kwiminyaka emininzi yokusetyenziswa kwemizi-mveliso ukulinganisela ukukhutshwa kweetship, amandla angcono, kunye nokusebenza kakuhle kokubhola.
I-drill bit ephuma kwi-geometry eqhelekileyo ukuya ekubonakaleni inzima ayiphucukanga kuloo balance. Iyenze yabuthathaka.
Iimpawu ezibalulekileyo ngokwenene
Ukuba ubunzima abuyonto ithembekileyo, yintoni ekufuneka abathengi bayijonge xa bevavanya umgangatho we-drill bit?
Iinguqu ezinentsingiselo zezi:
•Ubulukhuni.Emva konyango lobushushu, umda wokusika we-M2 HSS drill bit eyenziwe kakuhle kufuneka ufikelele malunga ne-HRC 63–65. I-M35 cobalt kufuneka ifikelele kwi-HRC 64–66. Amaxabiso obunzima ngaphandle kwale migangatho abonisa iingxaki ngonyango lobushushu - nokuba kukufudumala okungaphantsi, izinga lokucinywa elaneleyo, okanye ulawulo olubi lobushushu. Ubunzima bunokulinganiswa ngokuthe ngqo nge-Rockwell hardness tester.
•Ukwakheka kwezinto.Uhlalutyo lweSpectrometer (OES — Optical Emission Spectrometry) yeyona ndlela ithembekileyo yokuqinisekisa ukuba i-drill bit iqulethe na izinto ze-alloy ezifunwayo. Umxholo weCobalt, ipesenti ye-tungsten, i-vanadium — akukho nanye kwezi ebonakalayo okanye enokulinganiswa. Zifuna ukuqinisekiswa kwelebhu.
•Ukuchaneka kwejiyometri.I-angle yenqaku, i-angle ye-helix, ulungelelwaniso lweflute, kunye nemeko yomphetho we-chisel zonke zichaphazela ukusebenza kokusika. Ezi zilinganiswa ngezixhobo zokulinganisa ezibonakalayo okanye iiprojektha zeprofayili.
•Ukuhambelana kweqela.Isampulu enye edlulayo ayanelanga. Abathengi bemizi-mveliso bafuna ukusebenza okugcina yonke imveliso. Ukungaguquguquki kobunzima, ijiyometri, kunye nokugqitywa komphezulu kumakhulu okanye amawaka ezinto ngumbuzo wenkqubo yokuvelisa, awungombuzo wokuhlolwa kweyunithi enye.
•Ukugqitywa komphezulu.Umgangatho wokusila uyabonakala. Iimpawu zokusila ezirhabaxa, iindawo zeflute ezingalinganiyo, okanye iimpawu zokuxokozela ezibonakalayo kumphetho osikiweyo ziimpawu zeengxaki zenkqubo. Iqhekeza lokubhola eligayiweyo kakuhle libonisa iindawo zeflute ezicocekileyo nezigudileyo ezinejometri yomphetho ehambelanayo.
Oko Kuthethwa Yile Nto Kwizigqibo Zokufumana Izibonelelo
Xa umthengisi ethumela iisampulu, xhathisa imvakalelo yokuzivavanya ngobunzima. Uvavanyo olunentsingiselo kukucela isiqinisekiso sezinto, ukuhlola ijiyometri phantsi kokwandiswa ukuba kunokwenzeka, kwaye — kwiiodolo ezixabisa kakhulu — ucele idatha yovavanyo lobunzima okanye ukuqinisekiswa kwezinto ngokuzimeleyo.
Ubunzima abuyondlela imfutshane. Yingxolo.
Umgangatho we-HSS drill bit ubonakala kwisakhiwo sayo sentsimbi, unyango lwayo lobushushu, kunye nejiyometri yayo yomhlaba. Akukho nanye kwezi ebonakala kwisikali.
