Nyob rau hauv cov txheej txheem ntawm cov khoom lag luam tsim los ntawm kev sib txawv, kev txhim kho cov pwm zoo, uas cuam tshuam ncaj qha rau cov khoom zoo, tau dhau los ua txoj haujlwm tseem ceeb. Hauv kev tsim cov txheej txheem ntawm titanium alloy ntsia hlau pwm, kev ua haujlwm du thiab daim iav tiav tom qab kev ua tiav, uas yog ntog sib tsoo thiab polishing ntawm qhov chaw, yog cov txheej txheem tseem ceeb rau kev txhim kho pwm zoo. Mastering cov txheej txheem polishing tsim nyog tuaj yeem tsis tsuas yog txhim kho qhov zoo thiab kev pabcuam lub neej ntawm titanium alloy ntsia hlau pwm, tab sis kuj tseem ua kom cov khoom zoo. Tom ntej no, peb yuav ua kom nthuav dav ntau yam kev siv pwm polishing thiab lawv cov qauv kev ua haujlwm.
1. Mechanical Polishing
Mechanical polishing tshem tawm qhov protruding qhov chaw ntawm lub workpiece nto los ntawm kev txiav los yog inducing yas deformation ntawm cov khoom nto, thiaj li yuav tau ib tug du nto. Cov cuab yeej xws li roj pob zeb, wool log, thiab cov ntawv xuab zeb feem ntau yog siv los ntawm tes. Rau cov khoom ua haujlwm nrog cov kev xav tau zoo saum npoo av, ultra- cov txheej txheem polishing tuaj yeem siv tau. Ultra- polishing precision siv cov cuab yeej tsim tshwj xeeb, nias kom nruj tiv thaiv lub tshuab ua haujlwm ntawm lub tshuab ua haujlwm hauv cov kua polishing uas muaj cov abrasives, thiab ua haujlwm siab - nrawm nrawm. Siv cov thev naus laus zis no, qhov roughness ntawm lub workpiece tuaj yeem ncav cuag Ra0.008μm, uas yog qhov qis tshaj qhov roughness ntawm ntau txoj kev polishing; optical lens pwm feem ntau siv txoj kev no. Mechanical polishing occupies ib txoj hauj lwm loj hauv pwm polishing.
2. Tshuaj Polishing
Chemical polishing tso cai rau cov khoom siv los ua kom zoo dua rau kev ua kom lub ntsej muag microscopic es tsis yog qhov chaw so hauv cov tshuaj nruab nrab, yog li ua tiav qhov chaw du. Txoj kev no tuaj yeem polish workpieces nrog cov duab nyuaj thiab tuaj yeem txhuam ntau lub workpieces ib txhij, nrog kev ua haujlwm siab. Txawm li cas los xij, qhov roughness ntawm cov tshuaj polishing feem ntau yog Ra10μm.
3. Electrolytic Polishing
Lub hauv paus ntsiab lus ntawm electrolytic polishing yog zoo ib yam li cov tshuaj polishing, ob qho tib si cia siab rau cov kev xaiv ntawm kev sib cais me me ntawm cov khoom siv los ua kom lub ntsej muag du. Piv nrog tshuaj polishing, electrolytic polishing tuaj yeem tshem tawm cov teebmeem cathodic, ua rau cov nyhuv polishing zoo dua.
4. Ultrasonic Polishing
Ultrasonic polishing siv ultrasonic vibrations ntawm lub cuab tam hla -section los ua cov ntaub ntawv nkig nrog kev pab los ntawm kev ncua kev puas tsuaj. Tshwj xeeb, lub workpiece yog muab tso rau hauv ib qho abrasive ncua kev kawm ntawv thiab ib txhij nyob rau hauv ib tug ultrasonic teb. Kev vam khom ntawm lub oscillation ntawm ultrasound, cov abrasives ua kev sib tsoo thiab polishing ntawm qhov chaw ntawm lub workpiece. Lub zog macroscopic hauv kev ua ultrasonic yog me me thiab tsis ua rau deformation ntawm lub workpiece, tab sis kev npaj thiab kev teeb tsa ntawm cov cuab yeej yog qhov nyuaj.
5. Dej Polishing
Cov kua polishing yog nyob ntawm qhov kev txiav txim ntawm cov kua ntws thiab cov khoom abrasive nws nqa los txhuam qhov chaw ntawm lub workpiece, yog li ua tiav lub hom phiaj ntawm polishing. Hydrodynamic polishing yog tsav los ntawm lub zog hydraulic, thiab qhov nruab nrab feem ntau yog siv cov khoom siv tshwj xeeb (polymeric) nrog cov dej ntws zoo ntawm qhov tsis tshua muaj siab, tov nrog abrasives. Cov abrasives tuaj yeem xaiv ua silicon carbide hmoov.
6. Sib nqus Polishing
Sib nqus polishing siv cov hlau nplaum abrasives los ua ib qho txhuam txhuam hauv qab qhov kev txiav txim ntawm cov hlau nplaum kom zom cov workpiece. Txoj kev no muaj kev ua haujlwm siab, ua haujlwm zoo, thiab tswj tau yooj yim ua haujlwm. Nrog rau qhov tsim nyog abrasives, qhov nto roughness tom qab ua tiav tuaj yeem ncav cuag Ra 0.1 μm.
7. Electro-Tso tawm Ultrasonic Composite Polishing
Txhawm rau txhim kho polishing ceev ntawm workpieces nrog ib tug nto roughness Ra ntawm 1.6 μm los yog siab dua, ultrasonic tsis ua ke nrog ib tug tshwj xeeb siab - zaus nqaim- mem tes, siab -peak tam sim no fais fab mov yuav siv tau rau composite polishing. Txoj kev sib xyaw polishing no ua ke nrog qhov zoo ntawm ultrasonic thiab electro- paug polishing, ua kom zoo polishing efficiency thiab zoo.
Cov txheej txheem polishing sib txawv muaj lawv tus kheej cov yam ntxwv thiab siv tau ntau yam. Hauv kev ua haujlwm ntawm titanium alloy ntsia hlau pwm polishing txheej txheem, txoj kev tsim nyog polishing los yog kev sib xyaw ntawm ntau txoj kev yuav tsum raug xaiv raws li cov kev cai tshwj xeeb ntawm cov pwm, qhov nyuaj ntawm nws cov duab, thiab cov txheej txheem roughness yuav tsum ua kom tau raws li qhov xav tau polishing nyhuv, txhim kho pwm zoo, thiab nteg lub hauv paus rau kev ua tau zoo - zoo titanium alloy ntsia hlau khoom.
