Lub laum yog lub cuab yeej siv thoob ntiaj teb, tsis muaj leej twg, txawm tias qhov kev kho yooj yim tshaj plaws, tuaj yeem ua tau. Nws yuav tsum nco ntsoov tias rau txhua yam khoom muaj ib hom kev xyaum.
Qhov tseem ceeb yog kom nco ntsoov tias cov cuab yeej txiav yuav tsum nyuaj dua li qhov yuav tsum tau ua. Nyob ntawm cov khoom siv uas lawv yuav tho lub qhov, muaj cov tho rau ntoo, hlau thiab pob zeb. Kuj tseem muaj cov laum rau iav, nrog rau cov vuas. Lawm, nyob rau hauv txhua rooj plaub, cov cuab yeej tsim nyog yog siv. Txawm hais tias lub hom phiaj, txhua qhov kev xyaum muaj: lub shank, ua haujlwm thiab txiav cov khoom, cov khoom rau kev tshem tawm nti.
Dab tsi yog ntoo xyaum
ntoo yog cov khoom siv fibrous, thiab yog li ntawd, kom thiaj li yuav siv lub qhov nyob hauv nws, cov ntoo tshwj xeeb wood nrog cov duab tshwj xeeb yog xav tau. Muaj ntau ntau, tab sis feem ntau lawv siv cov hauv qab no:
- Kiab. Tsim los rau qhov drilling qhov, feem ntau yog los ntawm 3 mus rau 52 hli. Thaum kawg ntawm xws lilaum muaj cov lus qhia tshwj xeeb tsim los siv yooj yim.
- Thawj. Nws yog siv rau drilling tsis tuab boards, nrog rau fiberboard thiab chipboard. Xws li lub laum tsis muaj nti tshem tawm, thiab yog li nws tsis yooj yim heev los ua qhov sib sib zog nqus nrog nws. Txhawm rau kom tsis txhob yuav tag nrho cov teeb, koj tuaj yeem yuav ib lub laum ntoo (kho tau). Txoj kab uas hla ntawm qhov xyaum yuav txawv ntawm 15 mus rau 76 hli.
- Forstner laum. Siv rau drilling qhov muag tsis pom qhov. Nws tso cai rau koj los ua lub qhov los ntawm hauv qab tiaj tus, txawm thiab du. Feem ntau muaj txoj kab uas hla ntawm 10 mus rau 50 mm.
- Xov-crown rau ntoo. Nws yog siv rau drilling qhov loj uas ib tug pa xyaum ua tsis tau. Outwardly, nws yog ib lub nplhaib nrog cov hniav, nyob rau hauv nruab nrab ntawm uas muaj ib tug center xyaum. Ob peb daim feem ntau yog muag hauv ib lub teeb nrog txoj kab uas hla ntawm 19 txog 127 hli. Qhov tob drilling ntawm lub yas yog txwv, raws li txoj cai, nws yog 22 hli. Muaj cov qauv nrog qhov tob tob txog li 64 hli. Qhov kev xyaum no kuj siv tau los ua qhov hauv cov yas lossis phab ntsa ntub dej.
- Txoj-cutter. Nws yog siv rau lub qhov nrog cov duab complex, piv txwv li, los tsim roundings. Qhov txiav ntawm lub laum-mills yog nyob rau hauv qhov chaw, thiab yog li ntawd nws yog ib qho tsim nyog yuav tau xyaum ua ntej, thiab ces mus rau sab.
Cov lus qhia xaiv qhov xyaum
Thaum xaiv ib qho cuab yeej, tsis yog siv ntoo xwb, thawj qhov koj yuav tsum tau xyuam xim rau yog qhov tsos. Nyob rau hauv tsis muaj cov ntaub ntawv yuav tsum tau ib tug high-zoo cov khoom muaj pom sab nraud tsis xws luag (chips, khawb, dents). Txiav ntug yuav tsum yogCov xim sib xws thiab ua kom zoo zoo raws li qhov ntev.
Yam tom ntej koj yuav tsum tau xyuam xim rau yog xim ntawm lub laum. Nws yog qhov tshwj xeeb no uas yuav pab txiav txim seb hom kev ua tiav nws tau raug. Yog li, qhov xim ntawm lub laum tuaj yeem qhia peb li cas?
- Steel Grey. Tsis muaj kev ua tiav.
- Dub. Txhawm rau kom muaj zog, lub laum tau kho nrog superheated chav.
- Golden. Qhov no txhais tau hais tias lub laum tau dhau los ua haujlwm tshwj xeeb los daws qhov kev ntxhov siab sab hauv ntawm cov khoom.
- Zoo kub. Qhia tias qhov saum npoo ntawm cov cuab yeej no yog coated nrog ib txheej ntawm titanium nitride, uas yuav tsum ua kom nws muaj zog thiab lub neej ntev dua.
Thaum xaiv ib qho xyaum, koj yuav tsum tau xyuam xim tshwj xeeb rau cov chaw tsim khoom. Nws yog qhov zoo dua los yuav cov khoom lag luam los ntawm cov tuam txhab muaj koob npe. Qhov no yuav pab kom tsis tau tsuas yog cov khoom zoo xwb, tab sis kuj kom tsis txhob siv nyiaj tsis tsim nyog.
