Kev tsim cov kev xav tau rau cov saw hniav feem ntau tsom rau ntau yam: qhov tseeb qhov tseeb, cov khoom siv, kev kho cua sov zoo, thiab cov hniav machining raug. Vim tias cov saw hniav yog siab -kev ntxhov siab, qaug zog- cov cuab yeej siv tau yooj yim, kev ua haujlwm siab hauv kev tsim khoom yog qhov tseem ceeb.
Hais txog cov ntaub ntawv thiab kev tsim, sawb feem ntau siv siab - carbon steel, alloy steel, los yog siab - ceev steel strips, yuav tsum tau zoo uniformity thiab stability. Rolled steel sawb yuav tsum xyuas kom meej tias nws thickness thiab dav tolerances nyob rau hauv ntau yam tso cai; txwv tsis pub, nws yuav cuam tshuam rau kev sib dhos thiab txiav ncaj. Nyob rau tib lub sijhawm, cov khoom siv yuav tsum tsis txhob muaj qhov pom tseeb suav nrog, tawg, lossis lwm yam tsis xws luag los tiv thaiv kev tawg thaum siv.
Nyob rau hauv cov hniav machining, cov hniav pitch, hniav qhov siab, thiab cov hniav lub kaum sab xis yuav tsum zoo ib yam; txwv tsis pub, nws yuav ua rau muaj zog txiav kev vibration, txo efficiency, thiab txawm deviation. Cov hniav zoo li feem ntau yog tsim los ntawm stamping lossis sib tsoo, xav tau cov lus qhia hniav ntse thiab kev hloov pauv kom tsis txhob muaj kev ntxhov siab. Cov txheej txheem hniav sib txawv kuj yuav tsum tau siv rau cov hniav siv rau ntau lub hom phiaj; Piv txwv li, cov hniav ntxhib yog siv rau kev txiav ceev, thaum cov hniav zoo yog siv rau kev ua hlau los yog precision machining.
Kev kho cua sov yog ib kauj ruam tseem ceeb hauv kev tsim cov saw hniav, feem ntau suav nrog quenching thiab tempering. Qee cov khoom siv siab- kawg kuj tau dhau los ua qhov chaw induction hardening los ua kom cov hniav tawv thaum tuav cov tawv tawv ntawm sab nraub qaum. Kev tswj qhov kub thiab txias txias yog qhov tseem ceeb thaum kho cua sov; txwv tsis pub, tsis sib xws hardness los yog brittle fracture yuav tshwm sim.
Kev kho deg thiab kev tshuaj xyuas cov khoom tiav yog qhov tseem ceeb sib npaug. Cov kev kho saum npoo feem ntau suav nrog xeb- txheej tiv thaiv, nitriding, lossis plating los txhim kho hnav tsis kam thiab corrosion kuj. Ua ntej yuav tawm hauv lub hoobkas, kev sim hardness, checkness ncaj, thiab qaug zog lub neej sampling soj ntsuam kuj yuav tsum tau kom cov saw hniav ua pov thawj ruaj khov thiab txhim khu kev qha kev ua tau zoo nyob rau hauv tiag tiag ua hauj lwm tej yam kev mob.
