Amathuluzi Okusika I-Carbide Ehlanganisiwe

I-Tungsten carbide iyikilasi elisetshenziswa kakhulu lezinto zamathuluzi ze-high-speed machining (HSM), izinto ezinjalo zikhiqizwa inqubo ye-powder metallurgy, ehlanganisa i-hard carbide (imvamisa i-tungsten carbide WC) izinhlayiya kanye ne-soft metal bonding. Njengamanje, kunamakhulu ezingxenye ezihlukene ze-WC-based cemented carbide, iningi lazo lisebenzisa i-cobalt (Co) njengebhondi, i-nickel (Ni) ne-chromium (Cr) nazo ziyizinto ezivame ukusetshenziswa ezihlanganisayo, ngaphezu kwezinye i-alloying. izakhi zingengezwa. Kungani kunamamaki e-carbide amaningi kangaka? Umkhiqizi wamathuluzi wokusika ukhetha kanjani ithuluzi elifanele lenqubo ethile yokusika? Ukuze uphendule le mibuzo, ake siqale sibheke izici ezihlukahlukene ezenza i-carbide enosimende ibe yithuluzi lokusika elifanele.

Ukuqina nokuqina:I-WC-Co carbide inezinzuzo eziyingqayizivele kokubili ubulukhuni nokuqina. I-Tungsten carbide (WC) ngokwayo inobunzima obuphezulu (okungaphezu kwe-corundum noma i-alumina), futhi ukuqina kwayo akuvamile ukuncipha lapho izinga lokushisa lokusebenza likhuphuka. Nokho, ayinakho ukuqina obanele, okuyimpahla ebalulekile yamathuluzi okusika. Ukuze basebenzise ubulukhuni obuphezulu be-tungsten carbide futhi bathuthukise ukuqina kwayo, abantu basebenzisa i-metal bonding agents ukuze bahlanganise i-tungsten carbide ndawonye, ​​ukuze le nto ibe nobulukhuni obudlula kude obuwensimbi enesivinini esikhulu, futhi ngesikhathi esifanayo ingakwazi. ukumelana namandla okusika ezinqubweni eziningi zokusika. Ngaphezu kwalokho, ingakwazi ukumelana namazinga okushisa aphezulu okusika akhiqizwa umshini wejubane eliphezulu.

Namuhla, cishe wonke amathuluzi nama-blade e-WC-Co aboshwe, ngakho-ke indima yezinto eziyisisekelo ibonakala ingabalulekile kangako. Kodwa eqinisweni, i-coefficient ephezulu yokunwebeka yezinto ze-WC-Co (isilinganiso sokuqina, izinga lokushisa legumbi le-WC-Co licishe liphindwe kathathu kunelensimbi enesivinini esikhulu) elinikeza ukunamathela okungaguquki. isisekelo. I-WC-Co matrix nayo ihlinzeka ngokuqina okudingekayo. Lezi zakhiwo ziyizici eziyisisekelo zezinto ze-WC-Co, kodwa futhi kungenzeka ukwenza ngendlela oyifisayo izinto ezibonakalayo ngokulungisa ukwakheka kwezinto kanye nesakhiwo esincane lapho ukhiqiza impushana ye-carbide esimende. Ngakho-ke, ukufaneleka kwezakhiwo zamathuluzi enqubo ethile kuncike kakhulu kunqubo yokuqala yokuhlikihla.

Ukuphetha, ulwazi oluyisisekelo lwethuluzi ngalinye lokusika nokusebenza kwalo kubalulekile lapho ukhetha okulungile. Okucatshangelwayo kufaka phakathi into yokusebenza okufanele yenziwe ngomshini, uhlobo lwengxenye nomumo, izimo zomshini kanye nezinga lekhwalithi yendawo edingekayo ekusebenzeni ngakunye. Ngokusobala, usimende kuyisinqumo esihle sokwenza amathuluzi okusika, i-ZZBETTER Carbide Tools Company inesipiliyoni seminyaka engaphezu kweshumi sokukhiqiza cishe zonke izinhlobo zamathuluzi e-tungsten carbide.

Siyakwamukela ukuxhumana nathi uma unombuzo noma imfuneko mayelana namathuluzi e-carbide enosimende, siyakwazi nokwenza imikhiqizo engajwayelekile kuphela uma uhlinzeka ngemidwebo yakho.
