Hliav ib tus cwj mem tsis tau tawg nws - qhov no zoo li yooj yim ce ua tau muaj ntau nuances. Thaum tsis muaj kev txawj ntawm kev ntxuav tu graphite pas nrig thiab nws cov thav duab, ntau yam khoom siv tuaj yeem raug puas ntsoog. Cov kws tshaj lij kev kos duab thiab tus qauv sau ntawv tau mob siab rau kho cov ntse - qhov zoo ntawm lawv kev ua haujlwm yog nyob ntawm nws. Xaiv txoj hauv kev los ntxuav koj cov xaum raws li koj lub hom phiaj - txawm hais tias koj xav tau lub cuab yeej rau cov hobbyist kos duab, cim me me, lossis rau kev siv tswv yim.

Cov Lus Qhia
Kauj ruam 1
Hliav koj lub ntsej muag nrog lub ntsej muag yooj yim nrog qhov ceeb toom ceev faj, vim cov khoom tawg yooj yim feem ntau tawg ntawm lub hauv paus thaum siv cov cuab yeej no. Koj yuav tsum tsis txhob nias tus xaum qhuav; nws yog qhov tsim nyog kom tsis pub ntau tshaj plaub mus nrog lub ntsej muag hliav. Hloov cov khoom pheej yig ntau dua, thaum lawv dhau mus ua npub zoo nkauj sai sai. Hauv qhov no, thaum txhuam tus cwj mem qhuav, koj yuav tsum ua kom tau siv zog, thiab lub graphite yuav tawg.
Kauj ruam 2
Yuav cov xaum los siv lub tshuab hluav taws xob kom zoo yog tias koj nquag xaum koj cov xaum rau kev ua haujlwm hauv tsev lossis chaw ua haujlwm. Hauv chav saib xyuas cov tsev muag khoom ntawm lub khw muag khoom, koj tuaj yeem nrhiav cov khoom siv kho steel nrog kho kho me me, siv cov khoom siv tsis siv neeg, thiab txawm tias ntse-txuas rau cov ntsia hlau. Nrog rau qee qhov kev txawj ntse nrog kev pab ntawm cov ntse no, koj tuaj yeem muab tus xaum qhuav sai sai rau hauv kev txiav txim.
Kauj ruam 3
Txhawm rau tiv thaiv tus xaum los ntawm tawg thaum lub sijhawm ua haujlwm, nws yog qhov tseem ceeb kom txhim kho cov twj hauv qhov chaw. Ua tib zoo saib seb puas txhav txhav txhawm rau ruaj ruaj rau hauv taw lossis qhov tshwj xeeb tuav tseg-clamp. Nws tseem yog ib qho tseem ceeb kom xaiv jig nrog qhov sib txawv (lossis kho tau) kom pom cov diameters rau nyias thiab nyias tus cwj mem qhuav.
Kauj ruam 4
Siv tawv taub hau, rab riam ntse siv, los yog rab chais hniav rau cov cwj mem kom ntse. Pib nrog cov npoo, ua zoo kom tsis txhob nyias qhov graphite ntau dhau lossis nws yuav tawg. Koj txoj haujlwm yog txhawm rau ntxuav tus xaum los ntawm kev teeb tsa qhov kev deb ntawm lub ntsis ntawm tus pas nrig mus rau cov ntoo tsis npog ntawm 1-1.5 cm.
Kauj ruam 5
Tsis txhob rub ntoo ntau los ntawm cov xaum qhuav muag - qhov no yuav tiv thaiv lawv kom tawg. Ua ntau yam me me, ntau zaus txiav kom koj tsis txhob txiav cov hlau txhuas nrog rau cov kab tawg loj.
Kauj Ruam 6
Ua kom tiav cov taub ntawm cov cwj mem kom raws li hom ntawm cov hlauv uas yuav tsum tau. Nws tuaj yeem hlais qhov sib puag ncig; hov ob tog hauv daim ntawv ntawm incisor. Ua kom zoo li no thiab kom tsis txhob ua tus xaum qhuav, nws raug nquahu kom siv tawv ntoo.
Kauj Ruam 7
Cov hmoov txhuas tuaj yeem npaj tau kom nws yuav kos ob qho tuab thiab nyias kab hauv ib qho chaw. Txhawm rau ua qhov no, tso tus pas nrig los ntawm ntoo (lub graphite tseem tshuav tsis tau lawm), tom qab ntawd muab nws cov nplaig tiv thaiv qhov xwm txheej kub thiab hlau tiv thaiv cov ntawv toj roob hauv pes.
