Hla-txiav riam thiab tiaj tus- riam txiav lub qhov ncauj yog ob hom riam nrog kev siv thiab cov qauv sib txawv. Qhov sib txawv tseem ceeb nyob rau hauv lawv cov kev taw qhia txiav thiab cov duab ntawm lawv cov npoo.
I. Transverse Cutter
Txhais:Cov cuab yeej txiav nrog cov haujlwm tseem ceeb ntawm "transverse cutting". Nws cov ntug txiav feem ntau yog arc-zoo li tus lossis ncaj, thiab cov kev taw qhia txiav yog perpendicular rau qhov ntev / nplej ntawm cov khoom.
Hom kev siv:Txiav cov khoom xyaw (xws li rab riam hauv chav ua noj rau chop zaub, pob txha- chop riam rau cov pob txha), txiav cov ntaub, txiav daim ntawv, thiab lwm yam.
Core nta: Cov ntug txiav yog ntse heev. Qee qhov (xws li cov pob txha- chopping riam) muaj qee qhov tuab los txhim kho kev nruj, ua rau lawv haum rau cov khoom sib cais sai.
II. Pav ca-Edged Cutting Riam
Txhais:Ib rab riam nrog ib tug ncaj txiav ntug, qhov chaw txiav yog feem ntau sib npaug zos rau cov khoom nto, tsom rau "plam txiav" los yog "scraping".
Hom Kev Siv:Planing ntoo (woodworking flat-edged riam), trimming hlau nto, scraping khoom xyaw (xws li scraping noodles nrog ib tug scraper), thiab lwm yam.
Core nta:High flatness ntawm txiav ntug, lub kaum ntse ntse ntse, haum rau kev ua tiav ntawm cov khoom siv los yog nyias - txheej txiav.
