Lub peev xwm ntau lawm tseem nce ntxiv, tshwj xeeb tshaj yog nyob rau hauv cov kev cai ntawm kev tsim khoom loj, los ntawm kev ua haujlwm loj thiab kev kub ceev.
Txhawm rau kom ua tiav qhov yuav tsum tau ua haujlwm ntawm kev ua haujlwm siab, cov cuab yeej txiav tau zoo sib xws. Txhawm rau muab kev ua si tag nrho rau cov peev txheej ntawm cov cuab yeej txiav, lawv txhua tus muaj lawv tus kheej cov yam ntxwv kom haum rau ntau yam kev ua haujlwm.
Yog li ntawd, yuav tsum muaj kev nce qib tseem ceeb thiab txhim kho hauv cov khoom siv. Cov khoom siv ntau yam tam sim no siv feem ntau muaj cov khoom nram qab no: txo cov nqi tsim khoom thiab tsim khoom, muaj peev xwm tiv taus softening ntawm qhov kub thiab txias, tsis tshua muaj coefficient ntawm kev sib txhuam, kev hnav tsis kam, thiab thermal conductivity zoo. Vim muaj cov yam ntxwv xws li kev nqus txaus thiab kev cuam tshuam tsis zoo, cov khoom siv feem ntau siv tau raws li hauv qab no:
1: Alloy steel txiav cov cuab yeej
2: Pob zeb diamond cuab yeej
Peb: CBN polycrystalline laum txiav cov cuab yeej
