Paub txhua yam txog cobalt xyaum tseem ceeb heev rau txhua tus tswv tshiab. Thaum kawm lawv cov lus piav qhia, tau ua haujlwm nrog 14 hli cov cuab yeej hlau thiab lwm yam qauv, koj tuaj yeem tshem tawm ntau qhov ua yuam kev thiab tshawb pom qhov ua tau ntxiv. Nws tsim nyog kawm tshuaj xyuas cov khoom zoo sib xws, nrog rau cov txheej txheem rau lawv siv.
Nqe lus piav qhia
Lub ntsiab tseem ceeb ntawm cobalt xyaum yog siab tawv ntawm cov hlau . Qhov twg cov cuab yeej yooj yim ua kom sov sai, cov khoom cobalt-doped lav tau ntau dua kev ua haujlwm ruaj khov. Nws yog qhov nyuaj heev thiab nyuaj rau npaj txhua yam muaj peev xwm. Cov cobalt xyaum ua haujlwm zoo nrog cov haujlwm ua haujlwm ntsug. Nws yog qhov cuab yeej siv tau ntau yam haum rau ntau yam haujlwm.
Cov khoom siv tseem ceeb hloov pauv mus rau qhov ua kom nrawm hlau .… Vim tias siv cobalt (txog li 5%), yuam kom tshem tawm cov cua sov tuaj yeem zam tau feem ntau. Laum cov kaum ntse ntse (saum) 135 degrees. Nrog lawv cov kev pab, nws muaj peev xwm ua kom txawm tias cov nplaim du uas tsis muaj kev suav ua ntej suav nrog-qhov laum yuav tsis mus ib sab (raws li lawv hais, nws yog rau hom kev nyiam tus kheej).
Thiab tseem tsim nyog sau cia:
- tau txais qhov tshwj xeeb qhov qhov loj me;
- tsis muaj kev pheej hmoo ntawm burrs thiab lwm yam deformations;
- xoom qhov tshwm sim uas cov cuab yeej hauv thaj chaw ua haujlwm yuav "tom";
- siab tshaj plaws hnav;
- txoj kev hla ntawm txoj kev yuav luag ob zaug nrawm dua piv rau cov hlau yooj yim laum.
Kev tsim cov cobalt xyaum tuaj yeem raug cais raws li ib sab lossis ob sab
- Thawj hom cuam tshuam txog kev ua tiav ntawm kev txiav ib feem nruj me ntsis los ntawm ib sab.
- Hauv qhov hloov pauv thib ob, qhov tseeb, ob lub twj paj nruag tau muab tso rau hauv tib lub cev.
Ob lub tswv yim yog ua nrog cais qhov sib cais. Qhov zoo dua yog tias yog ib qho kev txiav ntug puas, koj tuaj yeem hloov mus rau qhov thib ob los ntawm kev yooj yim rov kho qhov laum hauv chuck.
Npav thiab xim
Txhua qhov cobalt xyaum ua tib zoo yog cim … Ua ntej tshaj plaws, lawv sau cov tsiaj ntawv raws cai ntawm cov ntsiab lus, thiab tom qab lawv qhia qhov feem pua. Yuav luag txhua qib hlau tau qhia nrog qhov qhia txog ntau yam kev sib xyaw. Hom tshaj plaws P6M5K5 txhais tau tias:
- tungsten - 6%;
- molybdenum - 5%;
- cobalt - 5%;
Nws yuav tsum tau sau tseg tias cov cuab yeej me dua 2 hli tsis tas yuav muaj cov ntsiab lus zoo li no hauv qhov cim … Feem ntau, kev tsim cov tshuaj muaj pes tsawg leeg tau xyaum ntawm kev xyaum nrog ntu ntu ntawm 2 txog 3 hli.
Yog tias qhov loj me ntawm cov khoom lag luam txawm tias loj dua, tom qab ntawv kos npe kuj tseem yuav muaj cov cim lag luam. Pawg neeg raug hauv cov dab neeg yog tsawg.
Tab sis, ntxiv rau kev kos, nws yog qhov yuav tsum tau coj mus rau hauv tus account thiab xim ntawm cov khoom . Txog rau qhov muag pom, nws yuav qhia tsis muaj tsawg dua ua ke ntawm cov tsiaj ntawv thiab tus lej. Ua ke dub thiab kub xim qhia qhov kev nkag mus ntawm "hnub so". Qhov kev hloov pauv ntawm kev kho cua sov tso cai rau koj los daws cov teeb meem sab hauv. Cov xim kub dawb qhia qhov sib ntxiv ntawm tsis yog cobalt nkaus xwb tab sis kuj yog titanium nitride.
Cov khoom no pab ua kom cov hlau muaj zog dua. Qib kev sib txhuam thaum ua haujlwm yuav tsawg dua li ib txwm. Kev xyaum dub yog tsim los ntawm kev ua nrog lub zog ua kom sov. Cov txiaj ntsig no txo qis kev hnav thiab tsim kua muag. Grey laum yuav tsum tau txiav txim siab zaum kawg - lub suab no hais tias tsis muaj kev kho kom tiav, thiab yog li ntawd qhov zoo ntawm cov khoom yuav qis heev.
Cov cheeb tsam ntawm kev siv
Cobalt-ntxiv cov cuab yeej drilling zoo heev haum rau kev ua haujlwm ob qho tib si tawv thiab tawv alloys . Nws tuaj yeem siv rau tooj liab thiab hlau nrog cov khoom tsis muaj zog. Lawv kuj sau tseg qhov tsim nyog ntawm cov cuab yeej siv no rau:
- acid resistant hlau;
- hlau tiv tshav kub;
- ua cov pwm ua los ntawm cov hlau;
- tuav cov kev sib txuas uas tiv taus xeb;
- kev ua ntawm cov khoom siv hlau alloyed;
- hla ntawm cam khwb cia hlau;
- ua haujlwm nrawm thiab raug ntawm qhov ntawm cov cuab yeej hlau txiav.
Hnav tsis kam cobalt xyaum muab lub neej ua haujlwm ntev. Koj tsis tuaj yeem ntshai ntawm qhov tsis zoo tshwm sim txawm tias ua haujlwm ntev thiab ua kom sov sov tseem ceeb. Kev tsim tshwj xeeb xav tawm ua rau nws ua tau kom raug thiab raug qhov tseeb qhov qhov loj. Tsis tas yuav siv cov khoom siv ntxiv rau txoj haujlwm ntawd . Muaj qhov zawj uas yog hauv av rau qhov tshem tawm tau sai tshaj plaws ntawm cov chips.
Nws kuj tseem tsim nyog sau cia tias muaj qhov txuas txuas ntxiv . Nws txo qhov kev pheej hmoo ntawm kev tawg. Vim li ntawd, lub sij hawm siv ntawm kev siv nce ntxiv. Cobalt additive lav zoo heev hauv cov hlau zas. Qhov no suav nrog cov hmoov txhuas thiab txhuas, tab sis tin thiab tooj liab kuj poob rau hauv pawg no.
Cov Lus Qhia Xaiv
Kev sib tw sib tw classic nrog cobalt ntxiv yog tsis tshua muaj tsim. Tab sis yog tias muaj cov khoom lag luam zoo li no, cov hauv paus txheej txheem rau lawv yog steel qib HSS . Xws li ib yam khoom zoo kawg nkaus txiav los ntawm hlau. Raws li qhov tshwm sim, nws dhau los ua kom muaj kev ruaj khov thiab ua tau ntev-gimbals. Siv xyaum nrog conical (kauj ruam) geometry txiav saum npoo, koj tuaj yeem yooj yim ntaus lub qhov nyob hauv txheej hlau nyias.
Lawv kuj tseem yuav pab kho qhov tsis xws luag los ntawm lwm cov cuab yeej txiav. Kev xaiv ntawm ib qho tshwj xeeb ntawm kev xyaum ua haujlwm tau txiav txim siab los ntawm hom hlau . Rau cov khoom ua haujlwm tuab, cov cuab yeej kub yog qhov zoo. Hauv cov xwm txheej hauv tsev, nws tsis tshua siv.
Tsuas yog qhov tshwj xeeb yog thaum muaj lub rooj cob qhia uas koj yuav tsum tau siv cov txheej txheem hlau nyias lossis ua haujlwm nrog qib cov khoom siv mos.
Nws yog qhov teeb meem sib txawv - tub ntxhais xyaum (nws tseem yog ib qho txiav ib xyoos ib zaug) … Xws li cov cuab yeej txiav zoo li lub tog raj kheej. Ib qho ntawm cov npoo yog txiav. Kev siv lub zog thaum siv cov cuab yeej zoo li no ntau zaus tsawg dua li lwm qhov. Qhov laj thawj yog qhov yooj yim: thaj chaw sib cuag yog me dua. Ib qho tub ntxhais xyaum yuav pab koj ntaus lub qhov loj. Tab sis qhov txiaj ntsig no tsis yog ib qho nkaus xwb: qhov ua tau zoo ntawm ntug kev ua tau zoo dua li thaum siv kev hloov kho kauv.
Cwj mem tiaj tus xyaum muaj kev hloov pauv ua haujlwm. Nrog lawv cov kev pab, nws dhau mus rau qhov xaum qhov uas tsis muaj qhov loj me thiab du. Ntau tus kws tshaj lij siv cov txheej txheem plaub tsis siv cov kauv, thaum lawv tseem pheej yig.
Feem ntau, kev cobalt cobalt hais txog qib Р6М5К5 . Nrov thiab qib 9К15 - nws muaj 15% cobalt. Cov khoom lag luam txawv ntawm tib hom raug xaiv HSS-E. Nws yog ib qho tsim nyog yuav tau coj mus rau hauv tus account qhov ntau ntawm cov qauv. Lub ntsiab gradation yog raws li hauv qab no:
- hom luv (ntev ntawm 2 txog 13.1 cm nrog ntu ntawm 0.03-2 cm);
- hom elongated (1, 9-20.5 cm thiab 0.03-2 cm, feem);
- xyaum ntev (5, 6-25, 4 cm thiab 0, 1-2 cm).
Thaum ua haujlwm drilling, koj yuav tsum tsom mus rau qhov tob ntawm kev nkag mus rau hlau. Hauv ntau qhov xwm txheej hauv tsev, tuab ntawm 14 hli yog txaus. Lwm qhov ntau thiab tsawg yog 6, 7x109, 4x75x43, 5x86x52 mm. Ib qho ntxiv, thaum xaiv qhov kev hloov kho laum, koj yuav tsum xyuam xim rau cov khoom lag luam ua lag luam, xws li:
- Bosch;
- "Tsiaj qus";
- nyiaj tsawg los ntawm USSR (lawv tsis tshua muaj, tab sis txawv hauv lawv qhov tsis txaus ntseeg).
Cov ntsiab lus ntawm kev siv
Tsis muaj lub ntsiab lus hauv kev siv cobalt laum me ntsis rau cov hlau tsis muaj zog. Nws yuav yog pov tseg ntawm cov cuab yeej zoo tshaj plaws. Nws ib txwm tsim nyog siv lub cuab yeej me me me dua li qhov xav tau ntawm cov channel .… Nyob rau hauv kev cuam tshuam ntawm kev cuam tshuam lub zog, nws yuav nce ntxiv. Tab sis qhov tob ntawm qhov drilled qhov yuav tsawg dua qhov ntev ntawm qhov laum. Nws yog qhov yuav tsum tau ua tib zoo tswj hom shank . Nws txawv nyob ntawm qhov kev siv rau kev xyaum lossis rauj rauj xyaum.
Tseem ceeb: Qhov ua tau zoo ntawm cobalt xyaum ntawm qhov tiaj, qhov ntxhib yog qhov tsawg. Nws yog qhov tsis ua haujlwm los laum cov khoom dua ntawm qhov nrawm. Dej nrog oleic acid los yog so luv yuav pab txo kom sov.
Txheeb xyuas cov txheej txheem
Cov txiaj ntsig zoo tau txais qauv "Xyaum Kws Tshaj Lij " … Kev tshuaj xyuas qhia tias cov cuab yeej no ua tau zoo tshaj 95% ntawm cov khoom lag luam loj. Kev mloog zoo kuj tseem them rau khoov zog thiab ua haujlwm ntev. Laum ntawm no version haum raws nraim. Nws tsis muaj qhov ua tsis tau tshwj xeeb.
Khoom hauv qab lub npe Bosch HSS-Co kuj yog nrov. Txawm tias qhov tseeb tias, raws li qee qhov chaw, lawv tau tsim tawm hauv Suav teb tsis cuam tshuam. Raws li kev sib piv FIT thiab KEIL hom , nov txhua yam tsis yooj yim li. Cov khoom FIT pheej yig dua. Tab sis ntawm KEIL ntau meej meej meej. Hais txog qhov liab, cov npe no nyob ntawm tus lej.
