Yuav qhia li cas yog tias lub laum me ntsis yog hss?
Koj puas paub tseeb yog tias koj laum me ntsis yog ua los ntawm cov hlau ceev (hss)? Nws yog ib qho tseem ceeb kom paub tias koj nyob nraum ua haujlwm nrog!
Qhov yooj yim tshaj plaws los qhia yog tias lub laum me ntsis yog hss yog saib rau cov cim cim ntawm lub ntsis nws tus kheej. Cov cim no feem ntau qhia cov hom khoom. Thaum cov xim muaj peev xwm qee zaum yog qhov tsis txaus ntseeg, nws tsis yog ib txwm ntseeg tau. Tus nqi kuj tseem yog qhov ntsuas, ua HSS cov menyuam muaj feem ntau kim dua cov roj carbon me.
Txheeb xyuas koj cov ntawv tho kev pab koj xaiv qhov yog rau txoj haujlwm. Cia peb tshawb nrhiav yuav ua li cas txiav txim siab seb koj lub laum me ntsis yog hss.
Qhov twg ntawm laum met Kuv nrhiav cov cim qhia tau qhia cov khoom hom?
Puas yog koj tab tom nrhiav cov cim ntawm koj laum me ntsis los txheeb xyuas nws cov khoom? Nov yog qhov twg saib!
Cov khoom hom yog feem ntau cim ntawm lub raj ntawm laum me me (ib feem uas nkag mus rau hauv cov tho chuck). Koj yuav pom cov cim zoo li "HSS," "High-ceev steel," "M2," lossis lwm tus lej uas qhia cov khoom muaj pes tsawg leeg. Qee zaum, qhov loj me ntawm me ntsis tseem cim muaj.
Cov cim ntawm lub laum me ntsis muab cov ntaub ntawv tseem ceeb ntsig txog nws cov khoom thiab kev siv. Cov hom khoom siv yog qhov tseem ceeb tshwj xeeb, raws li nws txiav txim siab lub ntsis nyuaj, kub tsis kam, thiab haum rau cov khoom sib txawv.
Lwm cov cim koj yuav pom ntawm lub laum me ntsis suav nrog qhov loj me (hauv nti lossis cov chaw tsim khoom siv), thiab qee zaum tus lej cim tau cov hlau tshwj xeeb. Piv txwv li, "M2"yog hom kev ceev ntau yam uas muaj kev sib tw zoo ntawm lub hardness thiab tawv.
Kuv ib zaug tau teeb ntawm tho cov khoom uas tau sau tseg, thiab nws nyuaj rau qhia dab tsi lawv tau ua los ntawm. Kuv tau xaus siv lawv ntawm ib qhov project uas yuav tsum muaj hss thiab lawv sai sai thiab tsis muaj qab hau. Qhov no tau qhia kuv qhov tseem ceeb ntawmyuav cov tho kevLos ntawm cov npe nrov nrov thiab ua kom paub tseeb tias lawv tau cim kom pom tseeb.
| Kev cim | Cov ntaub ntawv muab | Tseem ceeb |
| Hss | High-ceev hlau | Qhia tau me ntsis yog qhov tsim nyog rau drilling hlau, ntoo, thiab yas |
| M2 | Hom HSS | Muab cov ncauj lus kom ntxaws ntxaws txog cov hlau cov khoom |
| Qhov loj me (piv txwv li, 1\/4 ") | Txoj kab uas hla ntawm lub laum me ntsis | Xyuas kom koj siv qhov tseeb me ntsis rau txoj haujlwm |
Cov xim ntawm lub laum me ntsis ntseeg tau qhia kuv yog tias nws yog hss?
Puas yog koj vam tias yuav txheeb xyuas koj cov HSS laum me ntsis los ntawm nws cov xim? Cia peb pom tias qhov ntawd!
Thaum cov xim ntawm lub laum me ntsis tuaj yeem muab ib qho pov thawj txog nws cov khoom, nws tsis yog qhov qhia tau zoo. HSS cov khoom tuaj yeem tuaj hauv ntau cov xim, suav nrog ci nyiaj, dub, kub, thiab tooj dag. Cov xim feem ntau yog nyob ntawm kev kho mob saum npoo av rau me ntsis, ntau dua li cov khoom siv nws tus kheej.
Cov kev kho saum npoo ntawm lub laum me ntsis ua haujlwm pab ntau lub hom phiaj. Nws tuaj yeem txhim kho lub me ntsisCorrosion Kuj 1, txo kev sib txhuam, thiab txhim kho nws cov tsos. Cov txheej txheej dub oxide, piv txwv li, feem ntau siv ntawm HSS cov khoom los txhim kho lawv cov kub tiv thaiv thiab tiv thaiv xeb. Titanium nitride (tin) txheej, uas muab me ntsis cov xim kub, yog txawm nyuaj dua thiab ruaj khov.
Txawm li cas los xij, cov xim ntawm cov txheej tsis tas yuav qhia koj dab tsi me ntsis yog ua los ntawm hauv qab. Cov pa roj carbon hlau me me yuav yog coated nrog titanium nitride kom nws zoo li hss me ntsis. Yog vim li cas nws thiaj li zoo tshaj plaws los saib cov cim ntawm Shank kom paub meej tias cov khoom hom.
Kuv ib zaug yuav ib txheej ntawm "kub" laum "uas kuv xav tias yog Titanium-coated hss bits. Txawm li cas los xij, tom qab siv lawv ib pliag, Kuv pom tau tias lawv tsuas yog pheej yig carbon hlau khoom nrog cov xim kub xim. Cov txheej txheej nrawm nrawm nrawm tawm, thiab cov khoom noj dulled yooj yim heev. Qhov no qhia kuv kom tsis txhob cia siab rau xim ib leeg thaum txheeb xyuas lub laum khoom.
[1] Kawm paub tias kev kho kom zoo npaum li cas thiaj li txuas ntxiv rau lub neej tho kev txhim kho lawv cov corrosion tsis kam.
| Xim | Tej zaum kev kho mob nto | Khoom Siv Hluav Taws Xob | Kev ntseeg tau raws li qhov ntsuas |
| Nyiaj | Tsis muaj lossis Nickel plating | Yuav yog hss lossis carbon steel | Qi |
| Xim dub | Black Oxide | Feem ntau hss, txhim kho tshav kub | Nruab nrab |
| Kub | Titanium nitride (tin) | Yuav yog hss lossis carbon hlau, txhim kho lub hardness thiab ruaj khov | Nruab nrab |
Tus nqi ntawm kev sib txheeb li cas rau seb nws yog hss lossis tsis yog?
Puas yog koj xav paub yog tias tus nqi ntawm lub laum me ntsis tuaj yeem qhia koj yog tias nws yog hss? Peb nrhiav kom paub!
Tus nqi ntawm lub laum ntsis tuaj yeem yog qhov ntsuas ntawm seb nws puas yog HSS, tab sis nws tsis yog txoj kev ruam. HSS cov khoom lag luam feem ntau kim dua cov roj carbon hlau yog vim cov ntaub ntawv ntau dua thiab tsim khoom. Txawm li cas los xij, tus nqi kuj tseem tuaj yeem cuam tshuam los ntawm cov yam zoo li hom, qhov loj me, thiab txheej.
HSS tus laum khoom yog kim dua cov roj carbon steel vim tias lawv muaj cov ntsiab lus zoo li tungsten, molybdenum, thiab vanadium. Cov ntsiab lus no nce cov hlau lub hardness, kub tsis kam, thiab hnav tsis kam.
Txawm li cas los xij, qee leejCov Khoom Siv Hlautej zaum yuav kim dua ib co hss rau txhua yam xws li lub cim npe,Tshwj Xeeb Txheej Txheem Tshwj Xeeb 1, lossis cov qauv tsim tshwj xeeb. Yog li ntawd, nws tseem ceeb kom tsis txhob cia siab rau tus nqi thaum txiav txim siab cov khoom hom.
Kuv nco qab ib zaug nrhiav tau ib pawg ntawm cov laum cov khoom uas zoo li ib qho kev sib tw zoo. Lawv tau luv nqi tsawg dua li lwm cov pawg HSS tseg Kuv tau pom. Txawm li cas los xij, thaum kuv tau txais lawv lub tsev, Kuv pom tau tias lawv tau muaj cov txheej txheem carbon steel uas tau raug mislabeled. Tus nqi yog tus chij liab uas kuv yuav tsum tau them nyiaj ntau dua.
[1] Kawm txog cov txheej txheem tshwj xeeb tuaj yeem qhia tau tias lawv txhim kho tho ntsis ntev thiab ua haujlwm, ua rau koj cov peev txheej muaj nuj nqis.
| Yam tseem ceeb | Cuam tshuam rau nqe | Kev ntseeg tau raws li qhov ntsuas ntawm HSS |
| Khoom | HSS feem ntau kim dua cov hlau hlau | Tswj kav |
| Hom | Cov hom muaj npe zoo tuaj yeem them ntau dua | Qi |
| Daim plhaub | Tshwj xeeb Txheej Txheem Tshaj Tawm nce nqi | Qi |
Saib rau cov cim cim kom paub meej tias koj laum me ntsis yog hss. Xim thiab tus nqi tuaj yeem yog qhov qhia, tab sis lawv tsis yog ib txwm ntseeg tau. Paub koj cov ntsuas tho kom koj xaiv cov cuab yeej zoo!
