Txias dov mills paub txog lawv lub peev xwm los tsim cov ntawv hlau zoo nrog zoo heev nto tiav thiab qhov tseeb. Cov txheej txheem cuam tshuam nrog kev hla cov hlau los ntawm ib khub ntawm cov chais rau ntawm chav tsev kub, uas ua rau kom muaj zog thiab lub zog ntawm cov khoom. Siv lub tshuab txias kuj tuaj yeem tsim cov hlau nplaum nyias nyias, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua kom nruj thiab nruj. Tsis tas li ntawd, txias dov tuaj yeem txhim kho qhov chaw tiav thiab flatness ntawm cov hlau, ua rau nws haum rau ntau yam kev lag luam thiab kev lag luam siv.
Cov mills kub, ntawm qhov tod tes, yog tsim los tsim cov hlau ntawm qhov kub thiab txias, feem ntau saum cov khoom siv recrystallization. Cov txheej txheem cuam tshuam nrog kev hla cov hlau los ntawm ntau cov chais uas tuaj yeem tsim ntau yam duab thiab ntau thiab tsawg. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev kub dov yog lub peev xwm los tsim cov duab thiab contours, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom muaj qib siab ntawm formability thiab ductility. Tsis tas li ntawd, kub dov tuaj yeem txhim kho tag nrho cov khoom siv kho tshuab ntawm cov hlau, ua rau nws tsim nyog rau cov qauv siv hauv kev tsim kho thiab kev tsim khoom.
Qhov sib txawv tseem ceeb ntawm lub tshuab txias dov thiab kub dov zeb yog qhov kub ntawm cov hlau ua tiav. Txias dov yog nqa tawm ntawm chav tsev kub, thaum kub dov ua haujlwm cov hlau ntawm qhov kub thiab txias. Qhov kub sib txawv no ua rau muaj kev hloov pauv ntawm cov khoom siv xws li hardness, lub zog thiab formability, ua rau txhua tus txheej txheem tsim nyog rau kev siv sib txawv. Tsis tas li ntawd, qhov kawg ntawm qhov kawg thiab qhov tseeb ntawm qhov kawg ntawm cov khoom tseem cuam tshuam los ntawm cov hlau dov kub.
Hauv cov ntsiab lus, ob qho tib si txias dov mills thiab kub dov mills ua lub luag haujlwm tseem ceeb hauv kev ua hlau thiab muaj qhov tshwj xeeb zoo hauv kev tsim hlau thiab molding. Kev nkag siab txog qhov sib txawv ntawm cov txheej txheem no tuaj yeem pab koj xaiv txoj hauv kev zoo rau koj daim ntawv thov tshwj xeeb. Txawm hais tias tsim cov ntawv hlau zoo nrog nruj tolerances lossis tsim cov duab thiab cov duab, txias dov thiab kub dov muaj qhov tshwj xeeb zoo kom tau raws li ntau yam kev lag luam thiab kev lag luam.
