Kev tshuaj xyuas ua ntej kev kho kom sov yog ib tus txheej txheem tshuaj xyuas ua ntej los tshawb xyuas cov khoom tiav ntawm cov khoom lag luam zoo thiab qhov ntev raws li cov kev mob txuj ci, tuagkev zamTeeb duab thiab cov txheej txheem txheej txheem tom qab kev zam txim ua qauv tiav. Kev tshuaj xyuas yuav tsum tau them sai sai rau cov hauv qab no:
(1) Cov tsos yuav tsum tau dawb los ntawm cov kab nrib pleb, tsis muaj lub nplhaib carving nplhaib cua sov kev kho kom zoo nyob ntawm cov xeb, oxide tawv nqaij thiab lwm yam tsis xws luag.
(2) qhov teeb meem ntawmTuag Nco QabYuav tsum qhia cov qhov ntev, cov duab tshwj xeeb, cov ntu hla, cov duab thiab qhov chaw nyob.

(3) qhov loj me thiab precision ntawmTuag Nco QabYuav tsum tau kho cov chaw kub yuav tsum qhia cov khoom siv machining, kev ua kom zoo nkauj, txoj cai raug thiab raug thiab raug qhov tseeb.
(4) tus kuaj xyuas raws li tus naj npawb ntawmTuag Nco QabBatch 10% -20% chaw kuaj xyuas qis-siab, thaum lub pob ntawm cov chaw tshuaj lom zem hauv txoj kab, tuaj yeem nkag mus rau cov txheej txheem tshuaj xyuas. Cov kev zam txim uas tau soj ntsuam kom tsim nyog ua ntej quenching yuav tsum tau muab cia cais.
(5) Ua ntej quenching, xyuas cov khoom tso tawm ntawm cov khoom tiav, 1-2Zam tximYuav tsum muab tso rau cov qauv (cov khoom ntim thiab tawg thiab tawg
(6) Tom qab tshuaj xyuas, tus naj npawb ntawm cov khoom tiav, tus naj npawb ntawm cov khoom pov tseg uas muaj tseeb thiab cov lej kawg ntawm cov npav nrog, thiab kos npe los ntawm tus kuaj xyuas.
