    Daim ntawv thov thaj chaw thiab cov yam ntxwv ua

    Cov ntaub ntawv no ua tau zoo nyob rau hauv cov txheej txheem kho cua sov, thiab tom qab tsim nyog annealing, quenching thiab tempering kev kho mob, lawv tuaj yeem tau txais qhov zoo tshaj plaws hardness, plasticity thiab toughness kom tau raws li cov kev xav tau ntawm kev siv nyob rau hauv kev ua hauj lwm sib txawv.

    Thaum lub sij hawm machining, kev kho cua sov lub xeev ntawm cov khoom yuav tsum tau coj mus rau hauv tus account kom paub meej qhov zoo ntawm lub machining thiab smoothness ntawm lub tom ntej sib dhos.
