Kev tsom xam thiab kev siv ntawm hom thiab khoom siv
High Carbon Steel tig twj yog ib hom carbon hlau nrog carbon cov ntsiab lus ntawm 0.8% thiab 1.5%. Tom qab quenching thiab hardening, kev sib txhuam hauv kev txiav yog yooj yim tempered thiab muag muag, thiab yog hloov los ntawm lwm cov cuab yeej txiav xws li kev kub ceev steel. Feem ntau tsuas yog tsim rau cov ntawv muag hlau txiav cov khoom siv, feem ntau siv SK1, SK2, SK2, SK7 thiab lwm yam.
2 Cov Hlau Kub Ceev:
Kev kub ceev steel yog ib hom ntawm cov cuab yeej steel-puag, uas yog tsim los ntawm kev ntxiv W, CR, V thiab Co rau hauv cov pa roj carbon hlau uas muaj 0.7 ~ 0.85% carbon. Piv txwv li, kev kub siab steel 18-4-4 muaj 18% tungsten, 4% chromium thiab 4% vanadium. Kev kub ceev steel tig cov cuab yeej xws li SKH2, SKH4A, SKH5, SKH6, SKH9 thiab lwm yam tuaj yeem tsim cov kev sib txhuam ua kom sov li 6000C, uas tsim nyog rau tig xov nrog ceev tsawg dua 1000rpm.
3 TSIS MUAJ HLUAS LUB HLI CUA TXHUA TOOLS:
Cov alloy no, uas yog ua los ntawm cobalt, chromium thiab tungsten, nyuaj rau kev txiav thiab yog tsim los ntawm cov hlau nplaum. Nws tseem hu ua superhard cam khwb cia alloy. Tus sawv cev tshaj plaws yog cov xov tooj qub, uas muaj qhov muaj zog zoo thiab hnav tsis kam. Nws qhov nyuaj tsis cuam tshuam rau ntawm 8200 ° C, qhov ua haujlwm kub yog ntau dua li ntawm cov kub ceev steel. Nws yog qhov tsim nyog rau kev kub ceev thiab tob txiav kev ua haujlwm.
4 sintered carbide cov cuab yeej:
Lub cuab yeej carbide yog ua los ntawm 50% ~ 90% tungsten, nrog ntxiv ntawm titanium, Molybdenum thiab tantalum ua tus binder, thiab tom qab ntawd ua txhaum los ntawm cua sov. Lub cuab yeej carbide yog peb zaug nyuaj dua li lwm cov khoom siv, thiab tsim nyog rau kev txiav cov hlau lossis pob zeb tawv. Vim tias nws qhov xwm nkig, nws tsuas yog tsim tau rau hauv cov nplooj ntawv thiab tom qab ntawd welded rau ntau txoj hlua khi, thaum tus hniav hla dhau lossis tawg, lwm tus hniav tuaj yeem hloov lossis hniav tshiab yuav siv tau. Qhov cuab yeej tig no yog hu ua kev hloov khoom siv. Raws li cov khoom sib txawv ntawm cov txheej txheem carbide txiav cov cuab yeej raws li tus txheej txheem thoob ntiaj teb (ISO), cov cuab yeej carbide txiav tau muab faib ua peb pawg: P, m, K, uas cim los ntawm xiav, daj thiab liab feem: P yog tsim nyog rau kev txiav cov hlau, muaj rau pawg: P01, P10, P20, P30, P40 thiab P50, p01 yog qhov ua haujlwm siab ceev xa cov cuab yeej, cov lej me, siab coj tsis kam, P50 yog cov cuab yeej hloov ceev, cov lej loj , lub siab tawv, Hilt xiav kom paub. Chav K yog qhov tsim nyog rau kev txiav cov khoom siv tawv thiab tawv tawv xws li pob zeb thiab cov hlau cam. Muaj tsib chav kawm: K01, K10, K20, K30 thiab K40. K01 yog qhov ua haujlwm siab ceev hloov ua lwm yam thiab K40 yog cov cuab yeej siv hluav taws xob kub ceev tig los. M Ntawm Chav P thiab Chav Kawm M, haum rau txiav cov ntaub ntawv ductile xws li tsis yog? Thiab ntxiv mus, hom Hilt no tau pleev xim nrog xim daj kom paub nws.
5 CERAMIC TURNING COV CUAB YEEJ:
Tej hub tig cov cuab yeej yog ua los ntawm alumina hmoov nrog ib qho me me ntawm cov ntsiab lus ntxiv thiab tom qab ntawd sintered ntawm qhov kub. Lawv qhov nyuaj, ua haujlwm kub thiab txiav nrawm dua siab dua li ntawm Tungsten Carbide, tab sis vim yog lawv cov Brittleness, lawv tsis haum rau qhov tsis ua ntxiv lossis tig loj.
6 Lub Pob Zeb Txiav
Rau cov khoom tiav qib siab tiav, puag ncig lossis ntug-tsim kev lag luam pob zeb diamond tuaj yeem siv rau kev ua haujlwm lub teeb. Cov nplaim tawg tau tau, uas yog tsuas yog siv rau kev xa mus ntawm tooj liab hlau lossis lub teeb ci me me. Kev kub ceev yuav tsum tau siv nyob rau hauv tig, nrog tsawg kawg ntawm 60 ~ 100m / min thiab feem ntau 200 ~ 300m / min.
7 Boron Oxide Cubic Boron Oxide (CBN)
Cov cuab yeej no yog tsim rau machining nyuaj thiab hnav tiv taus hlau pawg alloy, nickel puag alloy thiab cobalt puag alloy.
