Qhov kev sib koom tes thev naus laus zis tuaj yeem yog faib ua ob pawg: ib qho yog qhov sib cav sib xyaw (uas yog, tsim cov ntaub ntawv xav tau los ntawm kev tshem cov khoom siv), thiab lwm cov yog cov paj ntxiv moulding), thiab lwm yam yog additive molding. Txog tam sim no, hais molding yog tseem cov cuab yeej thev naus laus zis nyob hauv thaj teb ntawm ib feem molding, thiab nws txoj haujlwm yog tsis muaj tseeb.
Kev rho tawm cov thev naus laus zis suav nrog ntau txoj hauv kev, thiab peb cov kev faib tawm yog feem ntau raws li qhov pib ntawm qhov tsis muaj npe. Txawm hais tias qhov txheej txheem kev sib cav kawg ntawm kev siv tshuab machining, cov peev txheej ntawm cov seem ntawm ntu yog qhov sib txawv heev. Yog li no, sib txuas sib sau yog tsuas yog muab faib ua peb pawg: profile sib txuas kev sib sau, thiab kev zam kev sib txuas sib npaug. Kab lus no tsuas yog tham txog kev sib txuas kev sib txuas.
Raws li qhia hauv daim duab hauv qab no. Los ntawm daim duab dhau los, peb tuaj yeem pom tau hais tias qhov seem ntawm seem hauv ntau hom kev sib txuas ntawm ob hom profiles, hlau tuav thiab hlau daim hlau. Qhov kawg cov duab thiab sab qhov tseeb yog tiav los ntawm ntau cov khoom siv tshuab ua, xws li cov xaim quav, tshuab, cov cav tov, khib nyiab drilling, thiab grinders. Qhov qauv no muaj cov txiaj ntsig zoo hauv qab no:
(1) Tus nqi qis tus nqi, vim tias lawv yog txhua cov qauv khoom, yog li cov nqi ua tiav yog cov tswj tau zoo;
(2) luv luv ua voj voog, koj tuaj yeem ncaj qha mus rau cov khoom lag luam los yuav nws, thiab yeej muaj cov khoom lag luam;
(3) Khoom siv zoo, vim hais tias nws yog tus qauv txheem, nws yog kev ntseeg tau ntau hauv kev tswj hwm kom zoo;
(4) Ua haujlwm ua tau zoo, tsuav koj tsis ntshai ntawm cov nqi ua haujlwm siab, koj tuaj yeem ua cov duab uas koj xav tau.
Qhov no moulding txoj kev tam sim no yog cov thev naus laus zis thev naus laus zis feem ntau. Ntau cov nroj tsuag siv cov nroj tsuag feem ntau tshwj tseg rau qee qhov nyiaj ntawm cov ntaub ntawv raw los xyuas cov nqi tswj thiab ua kom zoo ntawm kev ncig. Nyob rau tib lub sijhawm, nws kuj yog qhov feem ntau yuav ua txoj kev rau cov neeg kawm paub zoo. Tej zaum, koj yuav siv tag nrho koj lub neej ua ib tug txheej txheem txheej txheem tshuab tshuab, tsom mus rau ob peb cov txheej txheem rov ua dua. Txawm hais tias nws zoo li yooj yim rau saum npoo, nws yeej muaj cov kev paub tseeb, thiab ntau tus neeg pom tias nws nyuaj tau pib hauv lawv lub neej.(来源: ug 学习堂小胥收徒)
