Kev Kho Hniav Burs yog ib qho tseem ceeb ntawm Kev Kho Hniav Nruab Nrab Txhua Hnub. Cov cuab yeej siv qeeb, tsim rau kev txiav cov ntaub so ntswg xws li cov hniav txha hniav laus lossis pob txha, tuaj yeem muaj ntau yam thiab ntau dua ntse - Ntug dej thiab ntau yam txiav.
Keeb kwm siv nyob rau hauv kev npaj cov hniav kho kom zoo li cov khoom siv kev tsim kho kom zoo dua rau cov kev xaiv ntau yam los xa ntau yam kev kho hniav.
Ceev nrawm heev thiab ntawm cov khoom lag luam zoo, kev kho hniav yog ua los ntawm cov hlau, stainless hlau, tungsten carbide thiab pob zeb diamond haum.
Txhua lub caij los nyob hauv peb ntu - lub taub hau, caj dab thiab shank.
- Lub taub hau muaj cov hniav uas tig txiav cov ntaub so ntswg.
- Lub caj dab txuas rau lub taub hau, uas muaj cov hniav txiav lossis lub faus.
- Lub shank yog qhov ntev tshaj plaws ntawm lub tawg. Nws muaj ntau qhov kawg los txuas rau ntau hom tes.
Peb hom shank yog:
Ntev ncaj / mompiece burs (HP): Loj dua, ntev ncaj Shank Shank Shank thiab yog siv rau kev ua kom qeeb ceev.
Latch] Hom / Txoj Cai Angoo (RA): Cov ntawv sau no kom tsawg dua xws li - lub tes ua tes.
Kev muag khoom tuav (FG): Cov no yog siv nrog kev kub ceev tes.
Lawv siv nrog siab - cov tes ua haujlwm ceev thiab feem ntau yog cais los ntawm lawv cov duab - lub khob hliav qab lossis hmuv. Hauv kev xaiv txoj cai ntawm Bur, lawv cov khoom tshwj xeeb muaj nyob hauv lub ntsej muag hniav thiab muab tso rau, cov duab ntawm lub taub hau, thiab hauv kev ua tiav ntawm cov grit.
Hauv essence:
Rauv Burs - Tshem tawm cov hniav kom loj loj, kab noj hniav npaj, kev npaj khoom, thiab tsim cov ntsiab lus nkag thiab raws li tuaj yeem ua rau muaj:
Tiaj - Kawg Burs - Tshem tawm cov qauv hniav, teb chaws mentsorary - Kev npaj kho kom haum.
Txiv pear burs- Tsim ib qho undercut rau kev sau cov ntaub ntawv, khawb, trimming thiab xov.
Hla - txiav Tapered fissure - Qhov zoo tagnrho npaj whilst txwv lub tsim tsa - Up ntawm cov khib nyiab, xws li nyob rau hauv cov haujlwm yas.
Tiav Burs yog siv hauv kev ua tiav ntawm kev kho kom rov qab.
Zoo li cov xuab zeb, burs tuaj hauv cov qib sib txawv ntawm coarseness. Hauv cov ntsiab lus, cov abraigeness sib txawv kom haum cov haujlwm sib txawv. Lub harsher lub grit, cov hniav hniav ntxiv yuav raug tshem tawm. Finer grits yog qhov zoo tshaj plaws rau kev ua haujlwm uas yuav tsum tau nthuav dav fine
Qhov ntau ntawm burs muaj rau kws kho hniav yog loj heev, thiab xaiv cov kev xaiv tsim nyog tshaj plaws tuaj yeem txhim kho cov ntaub ntawv kuaj mob hauv tsev kho mob. Qhov tsim nyog, qhov no tuaj yeem ua tiav ntawm kev kho mob theem.
Tag nrho cov burs muaj:

Txhua tus tuaj hauv HP, RA thiab FG fittings.
Ib yam ntawm niaj hnub no yog muaj nyob rau hauv sterile, ib qho kev siv pob, ua kom muaj kev tiv thaiv kab mob ntau dua li niaj hnub no.
Ib Leeg - Siv Burs kuj raug nqi (tsis muaj qhov xav tau rau cov khoom tsis muaj menyuam), tsis muaj kev sib tsoo nrog cov khib nyiab) thiab tus neeg siab ntev - Cov phooj ywg (100% siv tau zoo dua li ua kom muaj kev nplij siab ntau dua).
Uas tau faus yuav tsum siv rau txhua txoj kev kho mob?
Kev phais cov burs: Siv rau hauv kev phais qhov ncauj, hnub no kev phais mob plab yog feem ntau ntawm tungsten carbide lossis pob zeb diamond, uas txhais tau tias lawv muaj zog thiab muaj kev ua tau zoo
Pob zeb diamond burs aRe Siv los zom cov ntaub so ntswg thiab txiav los ntawm porcelainin, thiab feem ntau siv nrog kev kub siab ntev kom tawm ntawm qhov ua tiav.
