Lub tshuab txias dov yog lub tshuab ua haujlwm siv hauv kev lag luam hlau los txo cov tuab lossis hloov cov duab ntawm cov hlau, feem ntau yog hlau, ntawm chav tsev kub. Cov txheej txheem no yog txawv los ntawm kub dov, uas yog ua nyob rau hauv siab kub los txhim kho hlau ductility thiab formability.
Nyob rau hauv ib lub tshuab txias dov, cov hlau dhau los ntawm cov txheej txheem ntawm cov chais uas siv lub zog kom flatten thiab zoo li nws. Kev ua dov tsis tsuas yog hloov cov hlau qhov ntev tab sis kuj txhim kho nws cov khoom siv kho tshuab, xws li hardness, tensile zog, thiab nto tiav. Txias dov yog qhov zoo dua rau kev tsim cov khoom precision thiab cov khoom siv vim nws muaj peev xwm ua tiav qhov kev ua kom zoo dua qub thiab qhov chaw du.
Tsis tas li ntawd, txias dov mills tuaj yeem nruab nrog ntau yam khoom siv thiab thev naus laus zis los txhim kho cov txheej txheem kev ua tau zoo thiab cov khoom lag luam zoo, suav nrog cov tshuab lubrication, cov cuab yeej tswj nruj, thiab cov cuab yeej siv tsis siv neeg. Cov yam ntxwv siab heev no ua rau muaj ntau yam thiab ua tau zoo ntawm kev ua kom txias txias hauv cov txheej txheem tsim khoom niaj hnub no.
