Tej teeb meem thiab kev daws teeb meem thaum siv high-speed steel saw hniav yog raws li nram no:
1.burrs ntawm qhov chaw txiav:qhov sib nrug ntawm cov saw hniav tsis tsim nyog, cov hniav saws hnav los yog cov hniav tawg.
Kev daws: Kho tus naj npawb ntawm cov hniav, nrhiav tus naj npawb ntawm cov hniav uas tsim nyog, thiab rov ua dua cov hniav saws (sharpening).
2.Overheating: Txiav cov ntaub ntawv ntom ntom lossis siv ntev tuaj yeem tsim kom muaj cua sov, ua rau cov hniav deformation, poob ntawm hardness, los yog cov khoom melting.
Kev daws: Ua kom muaj cua txias txaus nrog cov dej txias / roj nplua nyeem thaum ua haujlwm txiav. Txhob txiav thiab cia cov hniav kom txias yog tias nws dhau los ua overheated.
3. Cov hniav tawg:Kev quab yuam ntau dhau, kev noj zaub mov tsis zoo, lossis ntsib cov khoom nyuaj xws li cov rau tes tuaj yeem ua rau cov hniav tawg.
Kev daws:Kho qhov txiav ceev raws li cov khoom sib txawv thiab txo qhov kev txiav (feem) ceev
4.Txoj kev txiav nti tsis zoo:me me dhau ntawm tus hniav sib nrug, cov hniav tsis zoo, txiav nrawm nrawm heev.
Kev daws: Kho tus naj npawb ntawm cov hniav, nrhiav tus naj npawb ntawm cov hniav uas tsim nyog, rov kho cov hniav ntawm cov hniav, thiab txo qhov kev txiav ceev.
