Cov txheej txheem tsim khoom rau cov saw hlau feem ntau suav nrog kev npaj cov khoom siv raw, cov khoom siv ua haujlwm, kev kho cua sov, sib dhos, thiab kev tshuaj xyuas zoo. Ua ntej, cov ntaub ntawv tsim nyog-xws li siab- cov pa roj carbon zoo, hlau alloy, lossis stainless hlau- raug xaiv raws li cov saw hlau ua haujlwm, thiab cov khoom siv raw tau dhau los ua cov txheej txheem ua ntej xws li txiav thiab sib sau. Cov khoom xws li txuas daim hlau, pins, bushings, thiab rollers yog tsim los ntawm cov txheej txheem sib txawv; Piv txwv li, txuas daim hlau feem ntau yog tsim los ntawm stamping, thaum pins thiab bushings yog zoo li tus los ntawm machining kev khiav hauj lwm xws li tig thiab sib tsoo kom paub meej qhov tseeb thiab ua tau raws li kev sib dhos specifications.
Tom qab machining, cov khoom siv kho cua sov los txhim kho lawv lub zog, hardness, thiab hnav tsis kam. Cov khoom tseem ceeb xws li cov pins thiab bushings, piv txwv li, raug rau cov txheej txheem xws li carburizing, quenching, thiab tempering kom ua tiav qhov tawv tawv thaum tuav cov khoom zoo sab hauv. Kev kho mob tsim nyog ntawm cov ntawv txuas txuas txhawb lub zog tensile thiab qaug zog tiv thaiv, yog li txhim kho cov saw hlau kev ntseeg siab nyob rau hauv lub caij nyoog thauj khoom.
Thaum cov khoom tsim thiab kev kho cua sov ua tiav, theem kev sib dhos pib. Thaum lub sij hawm sib dhos, cov khoom sib txuas -xws li cov hlau txuas sab hauv thiab sab nrauv, tus pins, bushings, thiab rollers- tau muab tso ua ke hauv ib ntus, thiab cov saw hlau raug kuaj xyuas qhov yooj thiab kev sib txuas zoo. Thaum kawg, kev tshuaj xyuas zoo xws li kev kuaj pom, ntsuas qhov ntev, ntsuas tensile, thiab kev sim ua haujlwm tau ua kom ntseeg tau tias cov saw hlau tiav tiav raws li qhov yuav tsum tau ua. Kev tswj nruj nruj ntawm cov txheej txheem ntau lawm txhim kho kev tsim khoom precision thiab kev pabcuam lub neej, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm lub tshuab ua haujlwm.
