polishing yog dab tsi?
Hauv kev tsim kho tshuab, polishing yog ib qho txheej txheem kho. Nws yog cov txheej txheem ntawm kev ua kom tiav pretreatments xws li txiav los yog sib tsoo kom muab ib tug du nto. Qhov tseeb ntawm cov duab geometry xws li kev ntxhib los mos ntawm qhov chaw (nto roughness), qhov tseeb qhov tseeb, flatness thiab roundness tuaj yeem txhim kho.
Ib qho yog "taag abrasive processing method" los ntawm kev txhim kho lub zog thiab kev sib tsoo zoo rau cov hlau, thiab lwm qhov yog "dawb abrasive processing method" uas cov nplej abrasive tov nrog cov kua.
Tsau kev sib tsoo cov txheej txheem siv cov nplej abrasive uas tau sib koom ua ke rau cov hlau kom polishing protrusions ntawm qhov chaw ntawm cov khoom. Muaj cov txheej txheem ua haujlwm xws li honing thiab superfinishing, uas yog tus cwj pwm nyob rau hauv tias lub sij hawm polishing yog luv dua li txoj kev sib tsoo dawb.
Nyob rau hauv txoj kev pub dawb abrasive machining, abrasive nplej yog tov nrog cov kua thiab siv rau kev sib tsoo thiab polishing. Qhov saum npoo yog scraped los ntawm tuav lub sab saum toj thiab hauv qab thiab dov ib slurry (ib tug kua uas muaj abrasive nplej) hla saum npoo. Muaj cov txheej txheem ua haujlwm xws li kev sib tsoo thiab polishing, thiab nws qhov chaw tiav yog zoo dua li cov txheej txheem ua haujlwm ruaj khov.
● Honing
● Electropolishing
● Super tiav
● Sib tsoo
● Dej polishing
● Kev vibration polishing
Nyob rau hauv tib txoj kev, muaj ultrasonic polishing, lub hauv paus ntsiab lus ntawm uas zoo ib yam li lub nruas polishing. Lub workpiece yog muab tso rau hauv lub abrasive ncua kev kawm ntawv thiab muab tso ua ke nyob rau hauv lub ultrasonic teb, thiab lub abrasive yog av thiab polished nyob rau saum npoo ntawm lub workpiece los ntawm txoj kev ntawm ultrasonic oscillation. Lub zog ua ultrasonic yog me me thiab yuav tsis ua rau deformation ntawm lub workpiece. Tsis tas li ntawd, nws kuj tuaj yeem ua ke nrog cov txheej txheem tshuaj.
