Kuv ntseeg tias ntau tus neeg paub tias hlau yog dab tsi? Hlau yog ib yam khoom siv sib nqus uas tsim nyob rau hauv xwm. Muaj ntau hom khoom no. Qee cov hlau tuaj yeem siv los ua cov khoom rooj tog, thiab qee cov hlau tuaj yeem siv los ua cov hniav nyiaj hniav kub. Feem ntau cov hlau yuav tsum tau polished thaum lub sijhawm ua tiav. Rau kev polishing hlau, cov khoom siv polishing thiab polishing feem ntau yog siv. Koj puas paub siv cov khoom siv polishing thiab sib tsoo hlau? Tam sim no Z-LION yuav muab cov lus qhia ntxaws rau koj.
Kev sib tsoo hlau thiab kev siv tshuab polishing
1. Kev txhuam hniav txhua yam
Kev txhuam hniav yog ib txoj kev txhuam hniav uas ua rau qhov chaw du thiab du los ntawm kev txiav thiab hloov pauv yas ntawm qhov chaw ntawm cov khoom kom tshem tawm qhov seem uas tau txhuam. Feem ntau,Pob Zeb Diamond Emery Strips, cov log tsheb wool, ntawv xuab zeb,pob zeb diamond polishing pads, lub log xuab zeb pob zeb diamond thiab lwm yam siv tau. Siv cov cuab yeej pab xws li turntables, kev sib tsoo zoo heev thiab kev sib tsoo tuaj yeem siv rau cov neeg uas muaj qhov xav tau zoo ntawm qhov chaw. Kev sib tsoo thiab kev sib tsoo zoo heev yog cov cuab yeej abrasive tshwj xeeb, uas raug nias rau ntawm qhov chaw ntawm cov khoom ua haujlwm kom raug tshuab hauv cov kua sib tsoo thiab kev sib tsoo uas muaj abrasive, thiab tig ntawm qhov ceev ceev. Siv cov thev naus laus zis no, qhov roughness ntawm Ra0.008μm tuaj yeem ua tiav, uas yog qhov siab tshaj plaws ntawm ntau txoj kev sib tsoo. Cov pwm lens optical feem ntau siv txoj kev no.
2. Kev txhuam tshuaj lom neeg
Kev txhuam tshuaj lom neeg yog kom tso cai rau cov khoom me me uas tawm hauv cov khoom kom yaj zoo dua li cov khoom concave hauv cov tshuaj lom neeg, yog li tau txais qhov chaw du. Qhov zoo tshaj plaws ntawm txoj kev no yog tias nws tsis xav tau cov khoom siv nyuaj, tuaj yeem txhuam cov khoom ua haujlwm nrog cov duab nyuaj, thiab tuaj yeem txhuam ntau cov khoom ua haujlwm tib lub sijhawm, nrog kev ua haujlwm siab. Qhov teeb meem tseem ceeb ntawm kev txhuam tshuaj lom neeg yog kev npaj cov kua txhuam. Qhov roughness ntawm qhov chaw tau los ntawm kev txhuam tshuaj lom neeg feem ntau yog ntau 10 μm.
3. Kev txhuam hniav electrolytic
Lub hauv paus ntsiab lus ntawm electrolytic polishing zoo ib yam li cov tshuaj polishing, uas yog, los ntawm kev xaiv cov khoom me me ntawm qhov chaw ntawm cov khoom kom ua rau qhov chaw du. Piv nrog tshuaj polishing, qhov cuam tshuam ntawm cathode reaction tuaj yeem tshem tawm, thiab cov nyhuv zoo dua. Cov txheej txheem electrochemical polishing yog muab faib ua ob kauj ruam: (1) Macroscopic leveling Cov khoom yaj diffuse rau hauv electrolyte, thiab qhov geometric roughness ntawm cov khoom nto txo qis, thiab Ra> 1μm. (2) Qis lub teeb leveling Anodic polarization, txhim kho qhov ci ntsa iab, Ra <1μm.
4. Kev txhuam hniav ultrasonic
Cov khoom ua haujlwm raug muab tso rau hauv cov khoom siv abrasive thiab muab tso rau hauv lub teb ultrasonic ua ke, thiab cov abrasive raug sib tsoo thiab txhuam rau ntawm qhov chaw ntawm cov khoom ua haujlwm los ntawm kev oscillation ntawm lub ultrasonic nthwv dej. Lub zog macroscopic ntawm kev ua ultrasonic yog me me, thiab nws yuav tsis ua rau lub workpiece deformation, tab sis nws nyuaj rau ua thiab teeb tsa cov cuab yeej. Ultrasonic machining tuaj yeem ua ke nrog cov tshuaj lom neeg lossis electrochemical txoj kev. Raws li kev xeb ntawm cov kua thiab electrolysis, kev co ultrasonic yog siv los do cov kua, yog li cov khoom yaj ntawm qhov chaw ntawm cov khoom ua haujlwm raug tshem tawm, thiab qhov xeb lossis electrolyte ze ntawm qhov chaw yog sib xws; qhov cavitation ntawm cov ultrasonic nthwv dej hauv cov kua kuj tseem tuaj yeem tiv thaiv cov txheej txheem xeb, uas yog qhov ua rau qhov ci ntsa iab ntawm qhov chaw.
5. Kev txhuam kua dej
Kev txhuam kua yog txhuam qhov chaw ntawm qhov workpiece raws li cov kua ntws ceev ceev thiab cov khoom sib txhuam uas nws nqa kom ua tiav lub hom phiaj ntawm kev txhuam. Cov txheej txheem siv feem ntau yog: kev siv tshuab abrasive jet, kev siv tshuab fluid jet, kev sib tsoo hydrodynamic, thiab lwm yam. Kev sib tsoo hydrodynamic yog tsav los ntawm lub siab hydraulic, yog li cov kua nruab nrab nqa cov khoom sib txhuam ntws rov qab hla qhov chaw ntawm qhov workpiece ntawm qhov ceev ceev. Cov nruab nrab feem ntau yog ua los ntawm cov tshuaj sib xyaw tshwj xeeb nrog kev ntws zoo hauv qab qhov siab qis dua thiab sib xyaw nrog cov khoom sib txhuam, thiab cov khoom sib txhuam tuaj yeem yog silicon carbide hmoov.
6. Sib tsoo thiab txhuam hlau nplaum
Kev sib tsoo thiab txhuam hniav sib nqus yog siv cov txhuam sib nqus los ua cov txhuam sib nqus hauv qab lub zog sib nqus los sib tsoo cov khoom ua haujlwm. Txoj kev no muaj kev ua haujlwm zoo, zoo, yooj yim tswj cov xwm txheej ua haujlwm thiab cov xwm txheej ua haujlwm zoo. Nrog cov txhuam sib nqus tsim nyog, qhov roughness ntawm qhov chaw tuaj yeem ncav cuag Ra0.1μm.
Feem ntau cov hlau polishing yuav muaj txiaj ntsig zoo dua tom qab polishing. Hlau polishing tuaj yeem ua rau cov hlau nto du thiab zoo nkauj dua. Feem ntau cov khoom rooj tog thiab cov hlau hniav nyiaj hniav kub yuav raug ua tiav thiab polished ua ntej muag hauv khw. Muaj ntau yam cuab yeej thiab khoom siv siv rau polishing thiab sib tsoo hlau, thiab lawv cov hauv paus ntsiab lus ua haujlwm kuj txawv. Thaum peb xaiv cov tshuab thiab khoom siv sib txawv, peb yuav tsum pib los ntawm nws lub hauv paus ntsiab lus.
