Insimbi enamandla kakhulu yengezwa ngamanani ahlukene wezinto ezixubene nensimbi.Ngemuva kokwelashwa kokushisa, izakhi ze-alloying ziqinisa isisombululo esiqinile, futhi isakhiwo se-metallographic ngokuvamile si-martensite.Inamandla amakhulu nobulukhuni obuphezulu, futhi ukuqina kwayo komthelela nakho kuphakeme kunezinsimbi ezingama-45.Amandla okusika ngesikhathi sokusika azoba phezulu ngo-25% -80% ngaphezu kwamandla okusika we-45, izinga lokushisa eliphakeme lokusika liwukuthi, futhi ukuphulwa kwe-chip kunzima.Ngakho-ke, ekukhiqizeni kwangempela, izinsimbi ezinamandla aphezulu zisika kanjani?
1. Ithuluzi
Ngokusika okumahhadlahhadla nokuphazanyiswa, ithuluzi liyadingeka ukuze libe nokumelana nokushaqeka okushisayo.Ngaphezu kwamathuluzi edayimane, zonke izinhlobo zezinto zamathuluzi zingasikwa.Lapho ukhetha izinto zamathuluzi, kufanele zikhethwe ngokuvumelana nezimo zokusika.
A. Insimbi enesivinini esiphezulu
Ukukhethwa kwensimbi esebenza ngesivinini esiphezulu sokusika insimbi enamandla amakhulu kanye ne-ultra-high-strength kufanele kusekelwe ezakhiweni, ukuma, indlela yokucubungula kanye nokuqina kwesistimu yenqubo, futhi kucatshangelwe ngokuphelele ukumelana nokushisa, ukumelana nokugqoka kanye nokuqina. ukuqina kwezinto zamathuluzi.Uma isistimu yenqubo inokuqina okuphezulu futhi iphrofayili yethuluzi ilula, isisekelo se-tungsten-molybdenum, i-high-carbon low-vanadium-equkethe i-aluminium high-speed steel noma i-tungsten-molybdenum-based high-carbon low-vanadium high-cobalt high- insimbi yesivinini ingasetshenziswa;ngaphansi kwezimo zokusika umthelela, i-tungsten-molybdenum ingasetshenziswa.High vanadium high speed steel.
B. Insimbi ye-Powder metallurgy enesivinini esikhulu kanye nensimbi ehlanganiswe nensimbi enesivinini esikhulu
I-powder metallurgy high-speed steel iyimpushana enesivinini esikhulu ecindezelwa ngokuqondile ekushiseni okuphezulu nokucindezela okukhulu, bese ihlanganiswa ibe yisimo sethuluzi esidingekayo.Ilolwa ngemva kokucubungula futhi inobulukhuni obuphezulu kanye nokumelana nokugqoka okuphezulu.Ifaneleka ngensimbi enamandla kakhulu futhi super.Ukusika insimbi enamandla amakhulu.
C. I-carbide enosimende
I-carbide enosimende iyithuluzi eliyinhloko lokusika izinsimbi ezinamandla kakhulu nezinamandla aphezulu.Ngokuvamile, ama-alloys amasha aqinile asebenza kahle noma ama-alloys aqinile kufanele akhethwe.
D. Imimese yobumba
Ukuqina kwayo nokumelana nokushisa kuphakeme kune-alloys eqinile, okuvumela isivinini sokusika izikhathi ezingu-1-2 eziphakeme kune-carbides enosimende.Ekusikeni kwensimbi enamandla amakhulu kanye nensimbi enamandla kakhulu, amathuluzi e-ceramic asetshenziswa ngokuyinhloko ekusebenzeni kweshidi lensimbi kanye nomshini wokunemba.
2. Ukusika inani
Ijubane lokusika lokuguqula insimbi enamandla amakhulu kufanele libe ngaphansi kuka-50% -70% kunejubane lokusika lensimbi evamile.Ukuphakama kwamandla nobulukhuni bempahla yokusebenza, ijubane lokusika kufanele libe phansi.Ijubane lokusika lensimbi enamandla amakhulu ukusika insimbi enamandla amakhulu ngu-(3-10) m/min, ithuluzi le-carbide (10-60) m/min, ithuluzi le-ceramic lingu-(20-80) m/min, ithuluzi le-CBN lithi (40 —220) m/min.Ukujula kokusikwa nokuphakelayo kuyafana nokwensimbi ephendukayo evamile.
3. Indlela yokuphulwa kwe-chip
Ngenxa yamandla aphezulu wensimbi enamandla amakhulu, akulula ukuphula i-chip ngesikhathi sokuguqula, okuletha ubunzima obukhulu ekusebenzeni kahle kokujika.Kuyadingeka ukunaka kakhulu lokhu ekucubunguleni.
