Tho yeeb nkab yog qhov tsis muaj lub tshuab rau tsuas yog cov khoom siv. Laum Yeeb Nkab thiab Laum Sij Hawm Ua Haujlwm Ntawm Pob Zeb Laum, uas muaj cov cawv zoo ntawm kev ua haujlwm ntawm pob zeb drilling
Tho yeeb nkab, tseem hu ua hlau, feem ntau yog ua los ntawm cov hlau, seem yog hollow hexagonal lossis cov qauv. Lub hom phiaj ntawm cov hollowness yog rau lub hom phiaj tshem tawm cov hmoov phom phom.
Cov duab ntawm lub laum yog xaiv raws li lub hardness thiab muaj pes tsawg leeg ntawm lub pob zeb. Muaj peb hom laum tshwj xeeb: ib qho chisel ib leeg, ob chav chisel thiab ntoo khaub lig. Muab ob npaug rau - txi thiab hla - tho siv tau tuaj yeem siv rau hauv pob zeb dav dav.
Muaj ob txoj hauv kev los txuas lub laum yeeb nkab. Ib qho yog kev sib xyaw ntawm cov yeeb nkab laum thiab tho kev ( Nyob rau lub sijhawm no yuav tsum yog Moton me ntsis yuav raug forged, feem ntau yog hu ua forging fiber lossis hloov laum. Lwm tus yog lub xaim xaim sib txuas nrog cov xov lossis taper, feem ntau siv hauv pob zeb tawv. Kev txiav ntawm lub ntsis yog inlaid nrog carbide cuab yeej hlau, feem ntau yog hu ua alloy ntsis. Qhov kom zoo dua ntawm hom tho yog tias lub laum yuav raug tshem tawm thiab hloov lub zog, txuag tau tus hlau, thiab txo tus nqi ntawm kev kho fiber ntau.
Lub laum me ntsis thiab tho yeeb nkab siv ua ke hauv cov txheej txheem drilling. Thaum drilling, siv tus luv luv draw yeeb nkab xaim loj kom qhib lub qhov me me, yog li cov laum me me, ib qho los ntawm ib qho los hloov qhov ntev rau qhov yuav tsum tau tob.
