Xaiv txoj cai jigsaw hniav rau ntoo loj txiav txim siab qhov ua tau zoo thiab qhov tseeb ntawm cov khoom txiav. Nws tsim nyog paub meej tam sim ntawd tias cov hniav txiav rau hluav taws xob jigsaws tuaj nyob rau hauv ntau yam duab, hom thiab ntau thiab tsawg. Ntawd yog, txhua yam khoom xav tau nws tus kheej cov ntaub ntawv.
Cia peb sim txheeb xyuas cov hniav txiav thiab saib seb, piv txwv li, cov ntaub ntawv hlau txawv ntawm cov ntaub ntawv ntoo. Yuav ua li cas xaiv ib lub canvas rau cov khoom ntoo tshwj xeeb kuj yuav tau tham hauv kab lus no.
Txoj saw hniav rau cov cuab yeej fais fab
Lub thickness thiab ceev ntawm txhua yam khoom yog txawv, uas tam sim ntawd imposes ib co kev cai rau qhov zoo ntawm cov hlau los xij. Qhov no kuj suav nrog qhov loj thiab cov duab ntawm cov ntaub ntawv, nrog rau lub kaum sab xis ntawm cov hniav. Muaj tsuas yog tsis muaj qauv thoob ntiaj teb, yog li koj yuav tsum tsis txhob yuav mus rau hauv kev lag luam tsis yooj yim txog "omnivorous" canvases.
Txawm tias koj muaj cov ntoo zoo tshaj plaws jigsaw, lawv tsis zoo li txiav hlau kom zoo. Ib yam li ntawd, cov ntawv hlau tsuas yog ib feem ntawm cov chipboard lossis yas (koj yuav tau txiav ntev thiab tawv).
Tom ntej, cia peb mus rau qhov kev faib tawmfiles.
Steel
Txhua cov hniav txiav, suav nrog jigsaw hniav rau ntoo, sib txawv ntawm cov hlau zoo. Txhua tus qauv muaj cov cim txheej ntawm lub shank, qhov twg cov khoom ntawm kev tsim khoom tuaj yeem txiav txim siab los ntawm txoj cai.
Piv txwv li, Makita ntoo jigsaw hniav yog ib txwm ua los ntawm cov pa roj carbon zoo uas cim "HC S". Hom canvas no haum rau txhua yam khoom siv ntoo, txawm tias nws yog ntoo, fiberboard, chipboard, plywood lossis txawm yas. Hauv peb cov ntaub ntawv (ntoo), nws tsis yog qhov nyuaj ntawm cov hlau uas tseem ceeb, tab sis nws elasticity.
Kev kos npe "HS S" txhais tau hais tias cov hniav yog ua los ntawm cov hlau tawv tawv thiab kev kub ceev, uas yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm nrog hlau ntawm lub teeb thiab nruab nrab pawg. Cov ntaub ntawv ntawm cov ntaub ntawv no yog qhov nyuaj dua, tab sis tsis muaj elasticity, uas yog, nws yog qhov yooj yim dua.
Marking "BIM" (biferrum) txhais tau hais tias muaj ob qho tib si ntawm cov khoom saum toj no, uas yog, nyob rau hauv ib tus neeg thiab hardness, thiab plasticity nrog yooj. Cov hniav zoo li no yog siv rau kev txiav cov hlau ntawm cov pab pawg laus thiab qee cov alloys nyuaj. Ntawm cov txee ntawm qee hom koj tuaj yeem nrhiav cov ntaub ntawv ntoo (Bosch, Gross) nrog cov cim no, tab sis koj yuav pom lawv ntev heev (thiab kim), yog li nws yog qhov zoo dua los siv "NS S" li niaj zaus.
daim ntawv "HM" txhais tau hais tias cov hniav yog ua los ntawm cov hlau tawv tawv. Cov ntaub ntawv ntawm hom no yog siv feem ntau hauv cov khoom siv ceramic, qhov twg muaj kev ua haujlwm ntom ntom nrog cov vuas thiab cov ntaub ntawv zoo sib xws.
Canvas size
Cov ntaub ntawv ntoo feem ntau yog tuab dua li cov hlau qub lossis yas, yog li cov ntaub ntawv jigsaw rau ntoo tuaj, raws li lawv hais, nrog cov npoo, uas yog, ntev. Yog tias cov khoom ntxhib, zoo li cov laug cam, nws yog qhov zoo dua los siv cov hniav tuab, thiab nyias nyias rau curly txiav. Tus qub no yooj yim dua los tsav hauv txoj kab ncaj nraim, thaum tom kawg yog yooj yim tig.
Teeth
Cov hniav nrog cov hniav loj yog tsim los ua haujlwm nrog cov ntoo mos, thiab nws yuav tsum tau muab sau tseg tias qhov loj dua cov fwj thiab qhov deb ntawm lawv, qhov dav ntawm cov kauj ruam txiav, uas yog, txiav yuav rougher. Tib txoj cai ua haujlwm nyob rau hauv qhov sib txawv: cov hniav tsawg dua - txiav kom zoo nkauj dua.
Tsis tas li ntawd, qhov zoo ntawm kev txiav yog feem ntau cuam tshuam los ntawm qhov dav ntawm cov fwj. Qhov me me, qhov tseeb thiab qhov raug txiav yuav ntau dua. Tab sis nws yuav tsum nco ntsoov tias qhov deb me me ua rau lub sijhawm ua haujlwm ntau, ua rau nws siv sijhawm ntau dua. Nws kuj tseem yuav pab tau kom nco ntsoov tias cov ntaub ntawv nrog cov xaim me me yuav tsum muaj kev nrawm dua los ntawm cov khoom siv hluav taws xob, yog li yuav tsum xyuas kom meej tias tsis yog lub cuab yeej lossis cov khoom kub hnyiab.
Nyob rau hauv lawv cov duab, cov hniav tuaj yeem yog oblique (ntawm lub kaum sab xis rau ntawm ntug ntawm cov hniav), lossis ncaj, zoo li daim duab peb sab isosceles. Ntxiv mus, es tsis txhob siv cov xov hlau li niaj zaus, koj tuaj yeem nrhiav tau hauv khw muag khoom txiav "nthwv dej", qhov twg txhua tus hniav tom ntej yog me ntsis hloov mus rau sab ntawm yav dhau los (feem ntau pom ntawm lub rhawv ntawm Makita hom). Cov hniav zoo li no feem ntau yog siv rau kev txiav kom huv si: countertops, chav ua noj pem hauv ntej thiabQee lwm yam me me ntawm ntoo thiab chipboard / fiberboard.
Yog tias peb xaus cov yam ntxwv ntawm kev xaiv cov hniav los ntawm cov hniav, peb yuav tau txais daim duab hauv qab no:
- tsis tshua muaj hniav - ntoo mos thiab curly txiav (cov ntaub ntawv tuab thiab nyias, feem);
- nruab nrab tus hniav - zoo nkauj txiav hauv chipboard, plywood thiab tiav ntoo;
- me me cov hniav - txiav cov yas thiab hlau hauv kab ncaj;
- nruab nrab beveled hniav - ntxuav txiav ntawm me me radii (cov ntxhuav, chipboard zoo, yas).
Sank
Muaj ntau hom shanks muag. Hom ntau tshaj plaws yog cov hniav nrog lub hauv paus semicircular thiab ob nres ze rau cov hniav. Cov ntaub ntawv zoo li no yog universal thiab yuav haum rau feem ntau cov jigsaws.
Qee lub npe tsim cov hniav tshwj xeeb rau lawv cov cuab yeej nrog qee cov shanks tshwj xeeb. Yog li ntawd, thaum lub sijhawm yuav khoom, nco ntsoov xyuas cov ntsiab lus no nrog tus neeg muag khoom. Tib txoj cai yeej muaj tseeb rau kev yuav cov cuab yeej ntawm hom no: nws yog qhov zoo dua los saib xyuas ib yam dab tsi universal thiab tsis thab nrog cov khoom siv finicky.
