Kev txhuam hniav yog dab tsi?
Hauv kev tsim kho tshuab, kev txhuam yog ib qho txheej txheem kho qhov chaw. Nws yog cov txheej txheem ntawm kev ua tiav kev kho ua ntej xws li txiav lossis sib tsoo kom muab qhov chaw du. Qhov tseeb ntawm geometry xws li cov qauv ntawm qhov chaw (qhov roughness ntawm qhov chaw), qhov tseeb ntawm qhov ntev, qhov tiaj tus thiab qhov puag ncig tuaj yeem txhim kho.
Ib qho yog "txoj kev ua cov khoom siv abrasive ruaj khov" los ntawm kev kho lub log sib tsoo tawv thiab zoo rau ntawm cov hlau, thiab qhov thib ob yog "txoj kev ua cov khoom siv abrasive dawb" uas cov noob abrasive sib xyaw nrog cov kua.
Cov txheej txheem sib tsoo ruaj khov siv cov noob abrasive uas tau sib txuas rau cov hlau los txhuam cov protrusions ntawm qhov chaw ntawm cov khoom. Muaj cov txheej txheem ua haujlwm xws li honing thiab superfinishing, uas yog tus cwj pwm hauv qhov tseeb tias lub sijhawm polishing luv dua li txoj kev sib tsoo dawb.
Hauv txoj kev ua haujlwm abrasive dawb, cov noob abrasive raug sib xyaw nrog cov kua thiab siv rau kev sib tsoo thiab polishing. Qhov chaw raug khawb los ntawm kev tuav qhov chaw los ntawm sab saud thiab hauv qab thiab dov cov slurry (cov kua uas muaj cov noob abrasive) hla qhov chaw. Muaj cov txheej txheem ua haujlwm xws li kev sib tsoo thiab polishing, thiab nws qhov tiav ntawm qhov chaw zoo dua li cov txheej txheem ua haujlwm abrasive ruaj khov.
● Kev txhuam hniav
● Kev txhuam hluav taws xob
● Kev ua tiav zoo heev
● Kev sib tsoo
● Kev txhuam dej
● Kev txhuam kom du thiab co
Ib yam li ntawd, muaj kev txhuam hniav ultrasonic, lub hauv paus ntsiab lus zoo ib yam li kev txhuam hniav nruas. Cov khoom ua haujlwm raug muab tso rau hauv qhov kev ncua abrasive thiab muab tso ua ke hauv thaj teb ultrasonic, thiab cov abrasive raug sib tsoo thiab txhuam rau ntawm qhov chaw ntawm cov khoom ua haujlwm los ntawm kev siv ultrasonic oscillation. Lub zog ua ultrasonic yog me me thiab yuav tsis ua rau cov khoom ua haujlwm deformation. Tsis tas li ntawd, nws kuj tseem tuaj yeem ua ke nrog cov txheej txheem tshuaj lom neeg.
