Ama-alloys okushisa aphezulu ama-alloys ayinkimbinkimbi anezingxenye eziningi ezingasebenza ngaphansi komkhathi we-oxidation wokushisa ophezulu kanye nezimo zokugqwala kwegesi.Zinamandla amahle kakhulu okushisa, ukuzinza kokushisa, kanye nezakhiwo zokukhathala okushisayo.Ama-alloys okushisa aphezulu asetshenziswa kakhulu ezinjinini ze-turbine yendiza kanye nezingxenye ezimelana nokushisa zezinjini ze-aerospace, ikakhulukazi amashubhu omlilo, ama-turbine blades, ama-vanes omhlahlandlela, namadiski ophephela, okuyizingxenye ezivamile zokusetshenziswa kwengxubevange yokushisa okuphezulu.Lezi zinkinga ezilandelayo kufanele ziqashelwe lapho kwenziwa ama-high-temperature alloy milling cutters.
Okwezisiki zokugaya ezisezingeni eliphezulu zengxubevange, ngaphandle kwabasiki bokugaya ekugcineni nabanye abasiki bemishini yokugaya enziwe nge-hard alloy, ezinye izinhlobo eziningi zabasiki bokugaya zenziwe ngensimbi esebenza ngesivinini esiphezulu.I-K10 ne-K20 zifaneleka kakhulu kuma-alloys aqinile asetshenziswa njengezigayo zokugcina, njengoba zimelana kakhulu nomthelela kanye nokukhathala kokushisa kune-K01.Lapho kugaywa ama-alloys asezingeni eliphezulu, unqenqema lwethuluzi kufanele lube bukhali futhi lumelane nomthelela, futhi i-chip hold groove kufanele ibe nkulu.Ngakho-ke, i-spiral angle milling cutter enkulu ingasetshenziswa.
Uma ubhoboza ama-alloys asezingeni eliphezulu, kokubili i-torque namandla e-axial aphezulu;Ama-chips anamathela kalula ku-drill bit, okwenza kube nzima ukuwaphula nokuwasusa;Ukuqina komsebenzi onzima, ukuguga kalula ekhoneni le-drill bit, nokuqina okungenamandla kwe-drill bit kungabangela kalula ukudlidliza.Ngenxa yalesi sizathu, kuyadingeka ukusebenzisa insimbi enesivinini esikhulu kakhulu, i-ultrafine grain hard alloy, noma i-carbide esimende ukwenza izinsimbi zokubhoboza.Ngaphezu kwalokho, kuwukuthuthukisa isakhiwo esikhona se-drill bits noma ukusebenzisa izingcezu ezikhethekile zesakhiwo esikhethekile.Uhlobo lwe-S oluqinile lwe-alloy drill bits kanye nezingcezu ezine zamabhande onqenqema zingasetshenziswa.Isici se-S-type hard alloy drill bits ukuthi azinayo imiphetho yangemuva futhi zinganciphisa amandla e-axial ngo-50%;Ikhoneni elingaphambili lesikhungo sokubhoboza lilungile, futhi i-blade ibukhali;Ukwandisa ubukhulu be-drill core kwandisa ukuqina kwe-drill bit;Kuwumkhawulo wokusika oyisiyingi ngokusatshalaliswa okunengqondo kwemigodi yokukhipha ama-chip;Kunezimbobo ezimbili zokufutha zokupholisa kalula nokuthambisa.Ngenhlanganisela yokwakheka kwegroove yokususwa kwe-chip enengqondo namapharamitha wosayizi, i-drill yebhande le-blade blade inyusa umzuzu we-inetia we-cross-section, ithuthukisa amandla kanye nokuqina kwe-drill bit.Ngale nto yokubhoboza, ngaphansi kwe-torque efanayo, ukuguqulwa kwayo kwe-torsion kuncane kakhulu kunokwakheka kwe-torsional ye-drill bit ejwayelekile.
Ikakhulukazi kuma-alloys aphezulu okushisa, ukuhlanganisa kunzima kakhulu kunensimbi evamile.Ngenxa yetorque ephezulu yokuthepha, umpompi "ulunywa" kalula embotsheni yesikulufu, futhi umpompi ujwayele ukuphuka noma ukuphuka kwamazinyo.Izinto zompompi ezisetshenziselwa ama-alloys asezingeni eliphezulu ziyafana nezinto zokubhola ezisetshenziselwa ama-alloys asezingeni eliphezulu.Ngokuvamile, izintambo zokuthinta ingxubevange yokushisa okuphezulu zisebenzisa isethi ephelele yompompi.Ukuze uthuthukise izimo zokusika zikampompi, ububanzi bangaphandle bompompi bokugcina bungaba buncane kancane kunompompi ovamile.Usayizi we-engeli yekhoni yokusika kampompi uzothinta ukushuba kwesingqimba sokusika, i-torque, ukusebenza kahle kokukhiqiza, ikhwalithi ephezulu, nempilo yesevisi kampompi.Naka ukukhetha usayizi ofanele.
