Hauv kev tsim khoom lag luam, qhov ua tiav ntawm qhov chaw ua haujlwm yog ib qho ntawm cov cim tseem ceeb uas siv los ntsuas nws qhov zoo. Nws tsis tsuas yog cuam tshuam rau cov khoom lag luam zoo nkauj tab sis kuj cuam tshuam ncaj qha rau lub workpiece hnav tsis kam, corrosion kuj, kev sib dhos precision, thiab kev ua tau zoo ntawm cov txheej txheem tom ntej xws li pleev xim lossis electroplating. Txhawm rau ua kom tau raws li qhov xav tau kev kho saum npoo, ntau lub tshuab ua haujlwm tau tshwm sim; ntawm lawv, lub thoob polishing tshuab sawv tawm raws li qhov kev xaiv zoo tshaj plaws rau kev txhim kho workpiece nto tiav, ua tsaug rau nws cov qauv kev ua haujlwm tshwj xeeb thiab siab - kev ua haujlwm tau zoo.
Lub thoob tshuab polishing-tseem hu ua lub thoob xov tshuab lossis centrifugal chim finisher- yog ib qho khoom siv uas siv cov tshuab vibration los yog cov qauv kev sib hloov los ua kom muaj kev sib raug zoo ntawm cov khoom ua haujlwm thiab qhov nruab nrab abrasive hauv lub thoob kaw. Los ntawm kev sib txhuam tsis tu ncua, dov, thiab micro- txiav kev ua, lub tshuab tau zoo tshem tawm cov burrs, nplai, thiab xeb los ntawm cov khoom ua haujlwm, thaum kawg ua rau lub ntsej muag zoo nkauj, ci ntsa iab. Nws qhov txiaj ntsig tseem ceeb yog nyob rau hauv nws lub peev xwm los ua batch- ua cov khoom me me, ua rau cov chaw ua haujlwm tsis tu ncua thiab muaj peev xwm ua tiav ib qho matte lossis daim iav -zoo li tiav.
Kev ua haujlwm siab ntawm cov cuab yeej no yog los ntawm nws txoj haujlwm ua haujlwm. Tag nrho cov txheej txheem tshem tawm qhov xav tau ntawm tus kheej phau ntawv tuav ntawm txhua qhov haujlwm; Hloov chaw, ib qho tshwj xeeb ntawm cov khoom ua haujlwm tau thauj mus rau hauv lub thawv ntim nrog rau ua ntej - xaiv cov khoom sib tov ntawm cov khoom siv abrasive (xws li polishing pob zeb), polishing compounds, thiab dej. Thaum lub tshuab ua haujlwm, lub thawv ua tiav ib qho kev sib dhos, ua rau cov khoom sib xyaw ua ke mus rau ib qho qauv ntawm kev ntws thiab kev sib tsoo. Nyob rau hauv qhov kev ua tau zoo no tsis tu ncua, microscopic nto irregularities ntawm lub workpieces yog maj mam abraded tam sim ntawd, ntse npoo ua rounded, thiab tag nrho cov saum npoo tag yog kho kom zoo rau ib tug tseem ceeb degree.
