Rau cov neeg ua haujlwm hlau, cov kws kho tshuab, thiab cov neeg nyiam DIY hnyav, ua tiav qhov huv, meej, thiab ua haujlwm zoo hauv cov hlau hnyav yog ib txoj haujlwm tseem ceeb. Cov lus qhia no tsom mus rau cov yam ntxwv, qhov zoo, kev siv kom raug, thiab cov txheej txheem xaiv rau HSS Cobalt cov khoom los pab cov kws tshaj lij paub txog kev yuav khoom txiav txim siab rau kev thov cov ntawv thov hlau drilling.
Nkag siab HSS Cobalt: Dab tsi ua rau lawv txawv?
Cov khoom tseem ceeb ntawm cov laum khoom no yog High-Speed Steel (HSS). Standard HSS yog ib qho alloy feem ntau muaj hlau, carbon, tungsten, molybdenum, chromium, thiab vanadium. Qhov kev sib xyaw ua ke no muab cov qauv HSS ntau qhov zoo dua cov khoom siv carbon steel: lawv tuaj yeem tiv taus qhov kub thiab txias ntau dua thaum lub sij hawm drilling, tiv taus hnav zoo dua, thiab khaws lawv cov tawv tawv kom ntev dua. Qhov tseem ceeb, lawv tuaj yeem siv tau ntawm qhov nrawm nrawm dua (li "siab-ceev").
HSS Cobalt cov khoom txhim kho lub hauv paus no los ntawm kev koom nrog feem pua ntawm cobalt (Co) rau hauv HSS alloy mix. Thaum tus qauv HSS yuav muaj me me ntawm cobalt (xws li, M2 HSS chav kawm feem ntau muaj nyob ib ncig ntawm 5%), qhov tseeb * HSS Cobalt * kev faib tawm xws li M35 thiab M42 muaj ntau ntau - feem ntau M35 muaj nyob ib ncig ntawm 5% cobalt, thiab M42 feem ntau suav nrog 8% cobalt.
Qhov sib ntxiv ntawm cobalt ho hloov cov khoom me ntsis:
1. Txhim kho Red Hardness: Qhov no yog ib qho khoom tseem ceeb. Liab hardness hais txog lub peev xwm ntawm cov hlau kom khaws nws cov hardness txawm nyob rau hauv siab kub mus txog ib tug npub liab kub. Raws li cov hlau drilling tsim hluav taws xob loj heev los ntawm kev sib txhuam, cov qauv HSS cov khoom tuaj yeem poob lawv cov tawv tawv thiab ua haujlwm tau sai dua. Qhov sib ntxiv ntawm cobalt ua rau HSS alloy tswj nws cov txiav ntug hardness ntawm qhov kub thiab txias ntau dua thaum xav tau kev ua haujlwm drilling. Qhov no ncaj qha txhais mus rau kev ua tau zoo dua hauv cov hlau tawv thiab hauv cov khoom hnyav.
2. Ua kom muaj kev puas tsuaj ntxiv: Cobalt ua rau muaj kev hnav ntau dua - cov khoom siv tiv taus. Qhov no txhais tau hais tias HSS Cobalt cov khoom tuaj yeem tswj tau lub ntsej muag ntse rau lub sijhawm ntev dua thaum drilling abrasive hlau lossis los ntawm kev ua haujlwm- cov chaw tawv.
3. Kev Txhim Kho Lub Zog: Cov cobalt alloy muab lub zog tag nrho rau lub laum me ntsis, txo qhov kev pheej hmoo ntawm kev tawg lossis chipping nyob rau hauv siab drilling siab los yog torque, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv nyuaj los yog thaum ntsib imperfections.
4. Kev tiv thaiv tshav kub zoo dua: Lawv muaj peev xwm tswj tau qhov kub siab dua txhais tau tias lawv tsis tshua muaj peev xwm anneal (soften) thaum overheated piv rau cov qauv HSS.
Cov ntawv thov tseem ceeb: Qhov twg HSS Cobalt Shines
Muab lawv cov khoom zoo tshaj plaws, HSS Cobalt laum khoom tshwj xeeb tsim thiab pom zoo rau:
* Drilling Hardened Steels: Nrog rau cov cuab yeej hardened.
* Drilling Stainless Steel (tshwj xeeb yog qib austenitic zoo li 304 thiab 316): Cov hlau no ua haujlwm hnyav sai thiab ua kom muaj cua sov thiab kev sib txhuam.
* Ua haujlwm nrog tawv Alloys: xws li titanium, Inconel, Hastelloy, thiab lwm yam hlau txawv.
* Drilling Cam khwb cia hlau: tshwj xeeb tshaj yog thaum machining cov haujlwm yuav tsum tau ceev dua.
* Drilling Manganese Hlau thiab lwm yam hlau abrasive.
* Cov xwm txheej yuav tsum muaj kev drilling ceev thiab / lossis hnyav pub.
Thaum lawv tuaj yeem xyaum cov hlau softer xws li txhuas lossis hlau me me, qhov ua kom pom tseeb thiab tus nqi -kev ua tau zoo ntawm HSS Cobalt cov khoom yog feem ntau hauv kev siv cov khoom nyuaj uas tus qauv HSS lossis lwm yam ntaub ntawv yuav ua tsis tau sai.
Cov txiaj ntsig ntawm Kev Xaiv HSS Cobalt Drill Bits
* Cov cuab yeej txuas ntxiv lub neej: Vim muaj kev hnav zoo dua thiab qhov tawv tawv liab, cov khoom cobalt ntev ntev dua li HSS tus qauv hauv cov hlau tawv. Qhov no txo qis lub sijhawm rau kev hloov pauv me ntsis thiab txo qis - cov nqi siv sijhawm ntev.
* Kev nrawm nrawm: Lub peev xwm tiv taus cua sov ntau dua tso cai rau cov neeg siv khoom siv tau nrawm dua qhov nrawm nrawm (RPM) piv rau cov qauv HSS hauv tib cov khoom siv nyuaj, txhawb kev tsim khoom. Nco ntsoov sab laj cov chaw tsim khoom RPM cov lus qhia.
* Qhov Zoo Tshaj Plaws Zoo: Ua kom lub ntsej muag ntse ntev dua yuav pab tsim cov qhov huv si nrog qhov ua kom zoo dua thiab ua kom ntev.
* Kev Ua Tau Zoo Tshaj Plaws: Txo kev tawg thiab chipping tiv thaiv cov khoom seem vim lub cuab yeej tsis ua haujlwm hauv lub qhov.
* Kev ntseeg tau: Kev ua tau zoo nyob hauv cov ntawv thov nyuaj ua rau cov neeg ua haujlwm muaj kev ntseeg siab.
Xaiv txoj cai HSS Cobalt Drill Bit: Xaiv Cov Qauv
Xaiv qhov tsim nyog me ntsis cuam tshuam ntau dua li tuav lub cobalt -labeled laum. Xav txog cov xwm txheej no:
1. Cobalt Feem pua:
* M35 / HSS-Co 5%: Muab qhov kev ua tau zoo ntawm kev ua tau zoo tshaj tus qauv HSS ntawm tus nqi pheej yig dua li M42. Sawv cev muaj zog sib npaug rau ntau daim ntawv thov kev tshaj lij hauv cov hlau tsis muaj zog thiab tawv tawv.
* M42 / HSS-Co 8%: Muab qhov siab tshaj plaws ntawm qhov tawv tawv thiab hnav tsis kam. Qhov zoo tshaj plaws rau cov haujlwm uas xav tau tshaj plaws uas muaj cov hlau tawv tawv, cov khoom hnyav, superalloys (Inconel, Hastelloy), thiab cov ntaub ntawv zoo heev xws li cam khwb cia hlau lossis manganese hlau. Feem ntau hais kom tus nqi hwm.
* Lub kaum sab xis: Lub kaum sab xis ntawm lub taub yog qhov tseem ceeb. Rau cov hlau tawv, lub kaum sab xis 135℃tau pom zoo tshaj li tus qauv 118℃pom ntawm cov khoom siv softer. Lub kaum sab xis 135℃yog qhov muaj zog dua nrog qhov luv luv chisel taw tes, faib kev ntxhov siab zoo dua thiab txo qhov nyiam taug kev ntawm qhov chaw nyuaj. Qee qhov tshwj xeeb taw tes geometry kuj muaj (piv txwv li, faib-cov ntsiab lus rau tus kheej-centering).
* Drill Bit Finish: Saib cov khoom nrog lub ci ci, polished tiav. Qhov no tsis yog qhov zoo nkauj xwb; nws pab txo kev sib txhuam thiab kub tsim thaum lub sij hawm drilling los ntawm kev txo cov nti adhesion. Dub-Oxide coated cov khoom muaj kev tiv thaiv xeb thiab lubricity me tab sis feem ntau ua haujlwm tsawg dua- taw qhia rau cov hlau tawv piv rau cov khoom siv cobalt polished.
* Shank Hom: Feem ntau cov qauv twist xyaum muaj ncaj shanks. Xyuas kom compatibility nrog koj xyaum chuck. Txo cov khoom shank (ntau ntau hauv cov khoom) tso cai rau lub taub hau loj dua kom haum cov chuck me me.
* Flute Design: Standard twist flutes yog qhov tseem ceeb. Deep flute designs muab kev txhim kho nti tshem tawm.
* Teeb tsa tus kheej: Txiav txim siab yog tias koj xav tau cov txheej txheem dav dav uas npog ntau qhov ntau thiab tsawg lossis qhov tshwj xeeb ntawm tus kheej rau cov haujlwm tshwj xeeb. Cov txheej txheem zoo tuaj yeem sawv cev tus nqi zoo.
