Matla a phahameng a tšepe a eketsoa ka litekanyo tse fapaneng tsa likarolo tsa alloying ka tšepe.Ka mor'a phekolo ea mocheso, lisebelisoa tsa alloying li matlafatsa tharollo e tiileng, 'me mohaho oa metallographic hangata ke oa martensite.E na le matla a maholo le boima bo phahameng, 'me ho tiea ha eona ho boetse ho phahame ho feta tšepe ea 45.Matla a ho itšeha nakong ea ho itšeha e tla ba 25% -80% e phahameng ho feta matla a ho itšeha a 45, mocheso o phahameng oa ho itšeha o, 'me ho robeha ha chip ho thata ho feta.Joale, tlhahisong ea 'nete, litšepe tse matla haholo li khaola joang?
1. Sesebelisoa
Bakeng sa ho itšeha ka thata le ho sitisoa, sesebelisoa se hlokeha ho ba le ho hanyetsa mocheso oa mocheso.Ntle le lisebelisoa tsa daemane, mefuta eohle ea lisebelisoa tsa lisebelisoa e ka khaoloa.Ha u khetha lisebelisoa tsa lisebelisoa, li lokela ho khethoa ho ea ka maemo a ho itšeha.
A. Tšepe ea lebelo le phahameng
Khetho ea tšepe e sebetsang ka lebelo le phahameng bakeng sa ho itšeha matla a phahameng le a matla a phahameng a matla a phahameng a lokela ho thehoa holim'a thepa, sebōpeho, mokhoa oa ho sebetsana le mokhoa o tsitsitseng oa tsamaiso ea ts'ebetso, 'me u nahane ka ho hlaka ho hanyetsa mocheso, ho hanyetsa le ho apara. boima ba sesebediswa.Ha tsamaiso ea ts'ebetso e e-na le boima bo phahameng 'me setšoantšo sa sesebelisoa se le bonolo, tungsten-molybdenum-based, high-carbon low-vanadium-containing aluminium high-speed steel kapa tungsten-molybdenum-based high-carbon low-vanadium high-cobalt high-cobalt lebelo tšepe e ka sebelisoa;tlas'a maemo a ho itšeha, tungsten-molybdenum e ka sebelisoa.Tšepe e phahameng ea vanadium e lebelo le phahameng.
B. Powder metallurgy high speed steel le Tin e koahetsoeng ka tšepe ea lebelo le phahameng
Powder metallurgy high-speed steel ke phofo e phahameng ka ho toba e hatelloa ka mocheso o phahameng le khatello e phahameng, ebe e kenngoa ka har'a sebopeho se hlokahalang sa sesebelisoa.E matlafatsoa ka mor'a ho sebetsa 'me e na le boima bo phahameng le ho hanyetsa ho apara ho phahameng.E loketse bakeng sa tšepe e matla le e phahameng haholo.Ho khaola ka tšepe e matla haholo.
C. Carbide e entsoeng ka samente
Carbide e entsoeng ka samente ke sesebelisoa se ka sehloohong sa ho seha litšepe tse matla le tse matla haholo.Ka kakaretso, li-alloys tse thata tse sebetsang hantle kapa li-alloys tse thata tse koahetsoeng li lokela ho khethoa.
D. Lithipa tsa Ceramic
Boima ba eona le ho hanyetsa mocheso li phahame ho feta li-alloys tse thata, ho lumella ho itšeha ka makhetlo a 1-2 ho feta li-carbides tse samente.Ha ho etsoa litšepe tse matla haholo le litšepe tse matla haholo, lisebelisoa tsa ceramic li sebelisoa haholo-holo ka ho sebetsa ka lakane le machining a nepahetseng.
2. Ho fokotsa chelete
Lebelo la ho itšeha la ho fetola tšepe e matla e phahameng e lokela ho ba 50% -70% tlase ho feta lebelo la ho itšeha la tšepe e akaretsang.Ha matla le boima ba lisebelisoa tsa mosebetsi li phahame, lebelo la ho itšeha le lokela ho ba tlase.Ho itšeha ka lebelo la tšepe e matla e phahameng ea tšepe e matla haholo ke (3-10) m/min, sesebelisoa sa carbide (10-60) m/min, sesebelisoa sa ceramic ke (20-80) m/min, sesebelisoa sa CBN ke (40). —220) m/min.Botebo ba ho khaola le ho fepa ho tšoana le bakeng sa tšepe e fetohang ka kakaretso.
3. Mokhoa oa ho senya chip
Ka lebaka la matla a phahameng a matla a matla a matla a phahameng a tšepe, ha ho bonolo ho senya chip nakong ea ho reteleha, e leng se tlisang bothata bo boholo ba ho sebetsa hantle ha ho fetoha.Hoa hlokahala ho ela hloko haholo ho sena ts'ebetsong.
