Papiso ea Lisebelisoa tsa Lebelo le Lebelo le Leholo le Cemented Carbide

High-speed steel (HSS) le carbide e samenteng ke lisebelisoa tse peli tse sebelisoang hangata liindastering tse fapaneng, haholo-holo ho seha lisebelisoa le lisebelisoa tsa mochini. Lisebelisoa ka bobeli li bonts'a thepa e ikhethang e etsang hore e loketse merero e itseng. Sehloohong sena, re tla bapisa le ho bapisa litšoaneleho tsa tšepe ea lebelo le phahameng le carbide e entsoeng ka samente, re lebisa tlhokomelo ho sebopeho sa bona, boima, boima, ho hanyetsa ho apara, le ts'ebetso ea kakaretso.

Moetso:

High-Speed ​​Steel: Tšepe ea lebelo le phahameng ke motsoako o entsoeng haholo-holo ka tšepe, carbon, cobalt, tungsten, molybdenum le vanadium. Lintho tsena tsa alloying li eketsa ho tiea ha thepa, ho hanyetsa ho apara, le matla a phahameng a mocheso.

Cemented Carbide: Carbide e entsoeng ka samente, e tsejoang hape e le tungsten carbide, e na le karolo e thata ea carbide (eo hangata e leng tungsten carbide) e kentsoeng ka tšepe e kopanyang joalo ka cobalt kapa nickel. Motsoako ona o fana ka thepa ka thata e ikhethang le ho hanyetsa ho roala.

Ho thatafala:

Tšepe e Phahameng ka ho Fetisisa: HSS hangata e na le boima bo tlohang ho 55 ho isa ho 70 HRC (sekala sa Rockwell C). Boemo bona ba ho thatafala bo lumella lisebelisoa tsa HSS hore li sebetse ka katleho ka har'a mefuta e mengata ea thepa, ho akarelletsa le tšepe, tšepe e sa hloekang le tšepe e entsoeng ka tšepe.

Cemented Carbide: Carbide e entsoeng ka samente e tsebahala ka ho thatafala ho feteletseng, hangata e fihla ho 80 ho isa ho 95 HRA (Rockwell A scale). Boima bo phahameng bo etsa hore lisebelisoa tsa carbide tse samente li be ntle bakeng sa ho etsa lisebelisoa tse thata tse kang li-alloys tsa titanium, litšepe tse thata le li-composite.

Mathata:

High-Speed ​​Steel: HSS e bonts'a matla a matle 'me e khona ho mamella tšusumetso e matla le meroalo e tšosang, e etsa hore e tšoanelehe bakeng sa ts'ebetso e sitisitsoeng ea ho itšeha le ea machining e boima. Ho tiea ha eona ho boetse ho thusa ho nchafatsa le ho fetola lisebelisoa.

Carbide e entsoeng ka samente: Le hoja carbide e entsoeng ka samente e thata haholo, e batla e brittle ha e bapisoa le HSS. E ka 'na ea robeha kapa ea robeha tlas'a tšusumetso e matla kapa meroalo e tšosang. Leha ho le joalo, limaraka tsa sejoale-joale tsa carbide li kenyelletsa boima bo ntlafetseng mme li ka mamella litlamorao tse itekanetseng ho isa ho tse bobebe.

Wear Resistance:

High-Speed ​​Steel: HSS e na le khanyetso e ntle ea ho apara, haholo ha e sebelisoa ka lebelo le tlase la ho itšeha. Leha ho le joalo, ka lebelo le phahameng la ho itšeha kapa ha ho etsoa lisebelisoa tse nang le abrasiveness e phahameng, ho hanyetsa ha HSS ho ka 'na ha se ke ha lekana.

Cemented Carbide: Carbide e entsoeng ka samente e tumme ka ho hanyetsa ha eona ka mokhoa o ikhethang esita le maemong a thata a mochini. Karolo e thata ea carbide e fana ka khanyetso e phahameng ea ho roala, e lumellang lisebelisoa tsa carbide ho boloka moeli oa tsona oa nako e telele.

Tshebetso:

High-Speed ​​Steel: Lisebelisoa tsa HSS li ipabola mefuteng e mengata ea lisebelisoa tsa ho seha ka lebaka la ho feto-fetoha ha tsona, ho tiea, le bonolo ba ho chorisa. Li loketse ts'ebetso ea machining ea sepheo se akaretsang 'me li na le litšenyehelo tse tlase ha li bapisoa le carbide e entsoeng ka samente.

Cemented Carbide: Lisebelisoa tsa carbide tse entsoeng ka samente li sebelisoa haholo bakeng sa ho sebetsa hantle haholo le ho sebetsa hantle haholo. Li sebetsa hantle haholo lits'ebetsong tse hlokang matla tse nang le lebelo le phahameng la ho itšeha, bophelo bo atolositsoeng ba lisebelisoa, le tlhahiso e eketsehileng. Leha ho le joalo, ka kakaretso li theko e boima ho feta lisebelisoa tsa HSS.

Qetello:

Lebelo le phahameng la tšepe le carbide e entsoeng ka samente ke lisebelisoa tsa bohlokoa ka bobeli indastering ea lisebelisoa tsa ho itšeha, e 'ngoe le e' ngoe e na le matla le mefokolo ea eona. Litšepe tse lebelo le phahameng li fana ka boima bo botle, ho feto-fetoha ha maemo, le ho boloka litšenyehelo, ho etsa hore e tšoanelehe bakeng sa mefuta e mengata ea lisebelisoa tsa machining. Ka lehlakoreng le leng, carbide e entsoeng ka samente e ipabola ka ho thatafala, ho hanyetsa ho roala, le botsitso ba mocheso o phahameng, e leng se etsang hore e be khetho e ratoang bakeng sa ho lokisa litšepe tse thata le lisebelisoa tse ling tse thata.

Ho utloisisa litlhoko tse ikhethang tsa ts'ebetso ea mochini le lisebelisoa tsa mosebetsi ho bohlokoa ho khetha thepa e nepahetseng. Lintlha tse kang lebelo la ho itšeha, ho thatafala ha lintho tse bonahalang, le bophelo ba lisebelisoa tse lakatsehang li tlameha ho nahanoa ka hloko. Qetellong, khetho pakeng tsa tšepe e phahameng ka potlako le carbide e entsoeng ka samente e tla itšetleha ka kopo e khethehileng le liphello tse lakatsehang.
