Ib tug thawj uas yog dab tsi?

Ib tug thawj uas yog ib yam ntawm tej uas siv ua ib yam. Txhua tus tuam thawj muaj cov khoom uas ua kom haum rau lub creation ntawm ib qho kev. Cov khoom no feem ntau yog ua los ntawm cov hlau high-grade, tungstencarbide, los yog ib alloy ntawm cobalt. Ib tug thawj uas presses mus ua ib yam twj paj nruas thiab to tseg tej khoom cuaj ntsawj pa. Qhov yoojyim qab txoj ib yam khoom no uas yuav tsum tau tsuas ib qho nqaij ntuag yuav tsim, ruaj txo cov nqi piv rau lwm yam kev ntau lawm.

Tus terminology rau ib tug thawj uas yuav ruam tag. Lub tshuab thiab cov khoom uas nws employs yog hu ua tus tuam thawj. Nyob rau hauv nws cov ntaub ntawv, ib tug thawj uas siv los ua kev cai, nws yog xim hlau feem ntau yam. Lub tshuab thawj ua qhov no los ntawm kev tshwj xeeb me ntsis tias gouges pliaj khoom ntawm ib nyoos ntu, zoo xws li cas txaug to tseg ntoo.

Cov khoom siv los ntawm ib tug thawj uas pab cov uas ua kom haum fiction. Piv txwv li, ib ntsis yuav ua ib feem ntawm ib lub cav ib kev tsim, qauv thiab xyoo ntawm ib lub tsheb. Thaum ntawd qhov pauv, kab tias vim lub khw tsim hom tshiab lub cav, ntawd xyov ntsis yog lawm xwb. Vim rau qhov yuav tsum tau yuav hloov loj hlob sai los ntawm tus coj tso rau cov khoom thaum siv, khoom uas yuav yooj yim kho.

Cov khoom nyob rau hauv ib tug thawj uas muaj kub tolerances thiab specifications. Feem ntau, thaum ib tug ntaub attempts hlais ib cov khoom ntawm tus qub hardness, ob yam khoom puas ntsoog los sis puas lawm. Vim li ntawd, thiaj li yuav phua tseg khoom tawg yooj yim rau ib ntu steel, lub ntsis thawj yuav tsum ua kom nyuab zog li hlau.

Taus khoom feem ntau yog los ntawm kev thaum lawv tseem steel, nws yog xim hlau cobalt andtungsten carbide. Yooj yim steel khoom no yooj yim dua vim tias lawv kuj tsis tshua muaj hardness. Tungsten carbide yog ib qho khoom tawg yooj yim vim nws siab hardness thiab melting point, tiam sis nws tseem heev nkig thiab nws chipping. Los txhawb lub zog uas yog hlau, nws yog xim hlau cobalt yog infused rau lawv. Txoj kev no tsub kom lub hardness ntawm cov hlau thiab lub xauv ntawm cov carbide.

Cov thawj tuam khoom muaj tsawg. Me lub tshuab thawj thiab muab tus nqi siab dua ntawm cov ntsis thaum tseem ua kom lub siab tseem tso cai rau. Thiab nws thiaj li tau kev co thaum txiav nyiaj. Kev co sab tseem ceeb heev vim tias nws thiaj li tau coj los ntawm tus ntsis, tsub kom tus muab laij thiab pab txoj kev tus ceev txog tej txheej txheem.
