Hauv lub ntiaj teb kev sib tw ua hlau, kev xaiv lub laum kom raug tsis yog tsuas yog hais txog qhov loj ntawm lub qhov xwb - nws yog hais txog kev tshawb fawb txog cov khoom siv. Rau cov kws tshaj lij uas ua haujlwm txog cov hlau nplaum tawv, hlau tsis xeb, thiab hlau cam khwb cia, kev sib cav feem ntau nqaim mus rau ob tus yeej loj:M35 vs M42 Cobalt laum ntsis.
Ob qho tib si yog cov hlau ceev ceev (HSS) qib uas tau ntxiv nrog cobalt, muab kev tiv taus cua sov zoo dua piv rau tus qauv HSS. Txawm li cas los xij, qhov sib txawv me ntsis hauv lawv cov tshuaj lom neeg muaj feem cuam tshuam rau kev ua haujlwm, kev ruaj khov, thiab kev siv. Niaj hnub no, peb rhuav tshem kev sib ntaus sib tua kom pab koj txiav txim siab yuav khoom zoo tshaj plaws rau koj lub Hoobkas.
Lub Chemistry Tom Qab Qhov Txiav
Qhov sib txawv ntawm ob lub ntsis no yog nyob rau hauv lawv cov cobalt thiab tungsten cov ntsiab lus.
M35 (HSS-Co 5%):Muaj kwv yees li 5% cobalt thiab ib qho me me ntawm tungsten. Cov hlau no muab kev nce siab ntawm qhov nyuaj thiab kev tiv taus cua sov (txog li 650 ° C) yam tsis muaj kev tawg yooj yim.
M42 (HSS-Co 8%):Muaj kwv yees li 8% cobalt thiab cov vanadium ntau dua. Qhov kev sib xyaw ua ke ntawm cobalt ntau dua no ua rau muaj qhov tawv liab zoo dua, tswj nws cov ntug txiav thaum kub txog li 700 ° C.
Kev Sib Piv Kev Ua Tau Zoo: Taub Hau-rau-Taub Hau
1. Kev Nyuaj Siab thiab Kev Hnav Tsis Taus
Thaum kuaj xyuas qhov Rockwell hardness (HRC), M42 feem ntau tau qhab nia siab dua me ntsis (65-67 HRC) piv rau M35 (64-66 HRC). Qhov no muab M42 ib qho zoo dua hauv cov ntaub ntawv abrasive xws li fiberglass thiab cov ntawv luam tawm circuit boards. Ntawm qhov tod tes, M35 muaj qhov "toughness" zoo dua, ua rau nws tiv taus chipping nyob rau hauv kev ntxhov siab lateral.
2. Kev Tiv Thaiv Kub
Hauv cov chaw tsim khoom ceev ceev uas qhov kev sib txhuam ua rau muaj cua sov heev, M42 ua tau zoo dua M35. Cov ntsiab lus cobalt 8% tso cai rau nws "khiav txias dua" rau lub sijhawm ntev dua, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm CNC ntau thiab kev tho rau hauv cov hlau tsis xeb tawv (316/304).
3. Kev Siv Nyiaj Zoo
Muaj qhov sib txawv ntawm tus nqi tseem ceeb. M35 feem ntau pheej yig dua thiab npog 80% ntawm cov kev xav tau dav dav hauv chaw ua haujlwm. M42, yog ib qho khoom siv super-cobalt zoo tshaj plaws, kim dua. Txoj cai yooj yim yog: Yuav M35 rau kev ua haujlwm ntau yam; yuav M42 rau cov haujlwm tshwj xeeb, xav tau ntau.
Koj Yuav Tsum Xaiv Qhov Twg?
Xaiv M35 Cobalt Bits yog tias:
Koj tab tom tho hlau tsis muaj zog, hlau cam khwb cia, lossis txhuas.
Koj xav tau ib lub ntsis ruaj khov uas tiv taus kev tawg thaum siv tes xuas.
Koj tab tom nrhiav tus nqi zoo tshaj plaws rau kev saib xyuas thiab kho dav dav.
Xaiv M42 Cobalt Bits yog tias:
Koj tab tom tho qhov hlau stainless lossis titanium uas muaj zog heev.
Koj xav tau lub cuab yeej siv tau ntev tshaj plaws thiab ceev tshaj plaws hauv cov tshuab tsis siv neeg.
Koj ua haujlwm nrog cov ntaub ntawv nyuaj heev uas cov khoom txheem tsis ua haujlwm tam sim ntawd.
Cov Qauv Lag Luam thiab Kev Muaj Khoom
Txij li xyoo 2026, kev hloov pauv thoob ntiaj teb mus rau CNC automation tau ua rau muaj kev thov ntau ntxiv rau M42 cobalt bits vim lawv muaj peev xwm tswj tau qhov kam rau siab ntawm qhov ceev siab. Txawm li cas los xij, M35 tseem yog tus muag khoom zoo tshaj plaws ntawm cov neeg cog lus ywj pheej vim nws ruaj khov thiab tus nqi qis dua.
Lub Tswv Yim Zoo: Txawm koj xaiv cov khoom siv twg los xij, xyuas kom koj siv cov kua txiav kom raug. Kev siv cov roj txiav uas muaj sulfur ntau tuaj yeem ua rau koj cov ntsis laum M35 lossis M42 siv tau ntev txog li 50%, tiv thaiv koj cov peev txheej thiab xyuas kom cov qhov huv dua.
Xaus lus
Qhov kev sib ntaus sib tua ntawm M35 thiab M42 cobalt drill bits tsis yog hais txog qhov twg "zoo dua" hauv lub tshuab nqus tsev, tab sis qhov twg "zoo dua" rau koj daim ntawv thov tshwj xeeb. Txawm hais tias M42 kav zoo tshaj plaws rau qhov kub thiab tawv heev, M35 tseem yog tus qauv kub rau kev ua haujlwm sib npaug thiab pheej yig.
Npaj txhij hloov kho koj cov cuab yeej siv? Xauj peb cov khoom siv laum cobalt M35 thiab M42 zoo tshaj plaws hnub no kom nrhiav tau qhov sib phim zoo tshaj plaws rau koj cov teeb meem ua haujlwm hlau.
