Thaum cov neeg yuav khoom nug peb txog HSS drill bits, ib qho ntawm cov lus nug feem ntau yog: "Qhov txawv ntawm M42, M35, M2 — thiab 4341 ne?
Nws yog ib lo lus nug uas ncaj ncees. Tag nrho lawv yog cov khoom siv hlau ceev ceev (HSS), thiab ntawm qhov chaw, lawv zoo li yuav luag zoo ib yam. Tab sis qib uas koj xaiv muaj qhov cuam tshuam tiag tiag rau koj lub tshuab laum ntev npaum li cas, nws ua haujlwm li cas hauv qhov kub, thiab seb nws puas haum rau cov khoom siv uas koj tab tom txiav.
Nov yog kev piav qhia yooj yim.
HSS Yog Dab Tsi, thiab Vim Li Cas Qib Thiaj Tseem Ceeb?
HSS yog txhais los ntawm High-Speed Steel — ib qho hlau sib xyaw ua ke uas tsim los txiav hlau ntawm qhov ceev siab yam tsis poob nws qhov tawv. Tsis zoo li cov hlau carbon, HSS tseem khaws nws cov ntug txiav txawm tias nws kub thaum lub sijhawm tho.
Tiam sis tsis yog txhua HSS zoo ib yam. Qib — M42, M35, M2, 4341, thiab lwm yam — yog hais txog cov khoom sib xyaw tshwj xeeb. Qhov sib txawv me me hauv cov ntsiab lus xws li tungsten, molybdenum, vanadium, thiab cobalt ua rau muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo.
Lus Cim: M42 siv txoj hauv kev sib txawv ntawm M35 - nws siv cov ntsiab lus molybdenum siab heev es tsis txhob siv cov tungsten hnyav, uas ua rau nws kub kub zoo dua ntawm tus nqi sib xyaw me dua.
HRC siab dua txhais tau tias zoo dua hnav tsis kam - tab sis kuj me ntsis brittleness. M42 yog qhov nyuaj tshaj plaws, tab sis nws xav tau kev teeb tsa ruaj khov, nruj kom tsis txhob chipping. 4341 yog qhov mos tshaj plaws thiab tawv tshaj plaws, uas ua rau nws zam txim rau kev siv dav dav.
M42 — Qib Ua Haujlwm Zoo Rau Cov Hlau Uas Nyuaj
M42 yog nyob rau sab saum toj ntawm HSS hierarchy. Nrog 8% cobalt thiab cov ntsiab lus molybdenum siab heev (HS2-9-1-8, tseem hu ua HSSCo8, SKH59, P2M9K8, lossis S500), nws tau tsim los rau cov ntaub ntawv uas yuav hnav sai sai rau lub laum HSS txheem.
Peb tab tom tham txog cov hlau nickel alloys, titanium, cov hlau tawv, cov superalloys uas tiv taus cua sov - cov ntaub ntawv uas aerospace, kev tiv thaiv, thiab kev tsim khoom siab heev vam khom. M42 tswj cov no vim nws tuaj yeem tiv taus qhov kub tshaj 680 ° C thaum tswj hwm qhov txiav zoo, ntse.
Qhov kev sib pauv yog tias M42 tsis khov dua li cov qib hauv qab nws. Nws ua tau zoo tshaj plaws hauv cov chaw ruaj khov, tswj tau qhov twg kev co tsawg kawg nkaus. Nws kuj kim dua - tab sis rau kev siv kom raug, lub cuab yeej siv tau ntev dua qhov ua rau nws tsim nyog.
M35 — Thaum Koj Tho Cov Khoom Siv Ruaj Khob
M35 ntxiv 5% cobalt rau hauv M2 lub hauv paus (yog li ntawd lub npe hloov HSSCo5 lossis HS6-5-2-5). Cov cobalt ntawd ua rau lub tshuab tiv taus cua sov ntau dua - txog li ntawm 630–650°C - thiab thawb qhov nyuaj mus rau 63–66 HRC.
Rau cov neeg faib khoom xa khoom rau cov lag luam xws li tsheb, HVAC, lossis kev tsim khoom me me - qhov twg cov haujlwm ua los ntawm hlau tsis xeb feem ntau - M35 yog qhov hloov kho tshiab zoo dua li M2. Nws nyuaj dua, tiv taus kev hnav ntau dua, thiab muab lub cuab yeej siv tau ntev dua hauv cov xwm txheej nyuaj yam tsis muaj kev txhawj xeeb txog kev tawg yooj yim zoo li M42.
Xav txog M35 ua qhov chaw zoo tshaj plaws: zoo dua li tus qauv HSS, tab sis tseem siv tau thiab txhim khu kev qha hauv ntau qhov chaw ua haujlwm.
M2 — Tus Txheej Txheem Uas Ua Haujlwm Rau Feem Ntau Txoj Haujlwm
M2 yog qib HSS uas siv dav tshaj plaws hauv ntiaj teb. Nws lub npe tag nrho yog HS6-5-2 (tseem hu ua SKH51 lossis P6M5), uas qhia txog nws cov khoom sib xyaw: 6% tungsten, 5% molybdenum, 2% vanadium — tsis muaj cobalt.
Nws yog cov khoom siv rau kev khawb av dav dav ntawm ntau yam hlau - hlau tsis muaj zog, txhuas, tooj liab, hlau cam khwb cia, thiab ntau ntxiv. Cov laum M2 yog cov khoom siv sib tsoo tag nrho, ruaj khov, thiab pheej yig. Rau feem ntau ntawm cov chaw ua haujlwm thiab chaw tsim khoom, M2 yog qhov koj xav tau.
Yog tias tus neeg yuav khoom tsis qhia qib, M2 yuav luag txhua zaus yog qhov lawv tau txais - thiab rau feem ntau ntawm cov ntawv thov, qhov ntawd zoo heev.
4341 — Qhov Kev Xaiv Qib Nkag Mus Rau Qhov Nyuaj, Muaj Ntau Yam
4341 (tseem sau ua W4Mo3Cr4VSi) yog qib tungsten-molybdenum HSS uas nyob qis dua M2 hauv kev ua tau zoo, tab sis muaj kev tawv thiab kev cuam tshuam zoo heev. Nws nrov tshwj xeeb hauv kev lag luam uas kev siv nyiaj tsawg yog qhov tseem ceeb tshaj plaws.
Piv rau M2, 4341 muaj qhov nyuaj qis dua thiab qhov nyuaj kub txo qis - txhais tau tias nws yuav tsis tuav tau zoo thaum kub siab. Tab sis rau kev khawb cov hlau mos dua lossis hauv cov ntawv thov uas cov laum feem ntau hloov pauv es tsis yog saib xyuas, nws ua tiav txoj haujlwm tau zoo thiab pheej yig.
4341 yog ib qho kev xaiv uas siv ntau rau cov pob khoom siv laum uas muag los ntawm cov khw muag khoom thiab cov khw kho vajtse, qhov twg tus nqi tseem ceeb dua li qhov ua tau zoo tshaj plaws. Nws tsis yog lub cuab yeej zoo tshaj plaws rau cov hlau tawv - tab sis rau kev ua haujlwm me me txhua hnub, nws khwv tau nws qhov chaw.
