Cov neeg feem coob xav tias stainless hlau yuav tsis xeb, qhov tseeb, nws zoo li ntau lwm yam hlau, kev sib cuag nrog cov huab cua cuam tshuam los ntawm ib puag ncig yuav oxidized xeb, ntxiv rau, stainless hlau nto workpiece tom qab siv tshuab xws li vuam, stamping, curling, kev kho cua sov thiab lwm yam txheej txheem los tsim ib txheej dub oxidation metamorphic hardening txheej, nyob rau tib lub sij hawm pom muaj ntau ntawm cov ntaub ntawv me me. liab qab qhov muag thiab mob lub kaum sab xis burrs, thiab lwm yam, uas yog feem ntau nyuaj rau tshem tawm los ntawm cov neeg kho tshuab txoj kev, cuam tshuam cov kev ua si ntawm cov yam ntxwv ntawm cov khoom workpiece nws tus kheej. Txhawm rau daws cov teeb meem no, tib neeg siv ntau txoj hauv kev los zom thiab txhuam cov hlau xws li stainless hlau. Txhawm rau daws cov teeb meem no, tib neeg siv ntau txoj hauv kev los zom thiab txhuam cov hlau xws li stainless hlau.

Stainless hlau ntoua tiavg - polishing kev faib tawm

1.1Mechanical polishing:Tshuab polishing yog los ntawm kev txiav, yas deformation ntawm qhov chaw ntawm cov khoom kom tshem tawm cov polished convex thiab tau ib txoj kev polishing du, feem ntau yog siv cov whitetstone sawb, wool log, sandpaper, thiab lwm yam., feem ntau yog phau ntawv ua hauj lwm, tshwj xeeb qhov chaw xws li lub nto ntawm lub teb lub cev, siv tau cov cuab yeej pab xws li lub rooj teb, super polishing txoj kev yuav tsum tau. Super xov polishing yog siv cov cuab yeej sib tsoo tshwj xeeb, hauv cov kua polishing uas muaj cov abrasive, nruj nreem nias rau ntawm qhov chaw ua haujlwm kom ua tiav qhov chaw, rau kev sib hloov ceev. Qhov saum npoo roughness ntawm Ra0.008μm tuaj yeem ua tiav los ntawm kev siv cov thev naus laus zis no, uas yog qhov siab tshaj plaws ntawm ntau txoj kev polishing. Txoj kev no feem ntau siv nyob rau hauv optical lens pwm.

1.2Tshuaj polishing:Tshuaj polishing yog kom yaj lub micro-convex ib feem ntawm qhov chaw ntawm cov khoom nyob rau hauv cov tshuaj nruab nrab preferentially tshaj lub concave ib feem, thiaj li yuav tau ib tug du nto. Lub ntsiab kom zoo dua ntawm txoj kev no yog tias nws tsis xav tau cov cuab yeej nyuaj, tuaj yeem polish lub workpiece nrog cov duab nyuaj, thiab tuaj yeem polish ntau workpieces tib lub sijhawm, nrog kev ua haujlwm siab. Cov teeb meem tseem ceeb ntawm cov tshuaj polishing yog kev npaj cov kua polishing. Qhov saum npoo roughness tau los ntawm tshuaj polishing feem ntau yog 10μm.

1.3Electrolytic polishing:Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li tshuaj polishing, uas yog, los ntawm kev xaiv dissolving me me protruding qhov chaw nyob rau saum npoo ntawm cov khoom kom lub nto du. Piv nrog tshuaj polishing, cov nyhuv ntawm cov tshuaj tiv thaiv cathode tuaj yeem raug tshem tawm thiab cov nyhuv zoo dua.

Cov txheej txheem electrochemical polishing tau muab faib ua ob kauj ruam: (1) macro leveling yaj cov khoom diffuses rau hauv electrolyte, geometric roughness ntawm cov khoom nto txo, thiab Ra> 1μm. (2) Tsawg lub teeb theem anodic polarization, nto brightness nce, Ra

1.4Ultrasonic 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 kev cia siab rau lub oscillation ntawm lub ultrasonic yoj. Ultrasonic ua macroscopic quab yuam me me, yuav tsis ua rau workpiece deformation, tab sis cov cuab yeej tsim khoom thiab kev teeb tsa nyuaj dua. Kev ua ultrasonic tuaj yeem ua ke nrog cov tshuaj lom neeg lossis cov txheej txheem electrochemical. Nyob rau hauv lub hauv paus ntawm kev daws corrosion thiab electrolysis, ultrasonic kev co yog siv los do cov tshuaj, kom cov khoom yaj nyob rau saum npoo ntawm lub workpiece yog sib cais, thiab corrosion los yog electrolyte nyob ze ntawm qhov chaw yog uniform. Ultrasonic cavitation hauv cov kua kuj tuaj yeem cuam tshuam cov txheej txheem corrosion, uas yog qhov zoo rau qhov ci ntsa iab.

1.5Dej polishing: Cov kua polishing cia siab rau qhov siab ceev ntawm cov kua thiab nws cov khoom los ntxuav qhov chaw ua haujlwm kom ua tiav lub hom phiaj ntawm polishing. Cov txheej txheem yog: abrasive dav hlau ua, kua dav hlau ua, hydrodynamic sib tsoo thiab lwm yam. Hydrodynamic sib tsoo yog tsav los ntawm hydraulic siab kom cov kua nruab nrab nqa cov khoom abrasive ntws los ntawm qhov chaw ntawm lub workpiece ntawm kev kub ceev. Qhov nruab nrab yog tsuas yog ua los ntawm cov sib txuas tshwj xeeb (polymer-zoo li cov khoom) nrog zoo txaus nyob rau hauv qis siab thiab tov nrog abrasives, uas yuav ua tau silicon carbide hmoov.

1.6Sib nqus sib tsoo polishing:Sib nqus sib tsoo polishing yog siv cov hlau nplaum abrasives nyob rau hauv qhov kev txiav txim ntawm magnetic teb los ua ib qho txhuam txhuam los zom cov workpiece. Txoj kev no muaj qhov zoo ntawm kev ua haujlwm siab, kev ua haujlwm zoo, kev tswj xyuas yooj yim ntawm kev ua haujlwm thiab kev ua haujlwm zoo. Nrog rau qhov tsim nyog abrasive, qhov nto roughness tuaj yeem ncav cuag Ra0.1μm.

Cov yam ntxwv cuam tshuam rau polishing zoo ntawm cov tuag Vim hais tias cov neeg kho tshuab polishing yog tsuas yog ua tiav los ntawm phau ntawv, polishing tshuab tseem yog lub ntsiab tseem ceeb rau cuam tshuam rau polishing zoo. Tsis tas li ntawd, nws tseem muaj feem xyuam rau cov khoom siv pwm, qhov chaw ntawm qhov chaw ua ntej polishing, thiab cov txheej txheem kev kho cua sov. Cov hlau zoo yog qhov yuav tsum tau ua ua ntej rau kev polishing zoo, yog tias cov hlau nto hardness tsis sib xws los yog muaj qhov sib txawv ntawm cov yam ntxwv, feem ntau tsim teeb meem polishing. Ntau yam kev suav nrog thiab qhov pores hauv cov hlau tsis zoo rau polishing.

3.1 Kev cuam tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov txheej txheem polishing Qhov nce ntawm hardness nce qhov nyuaj ntawm kev sib tsoo, tab sis qhov roughness tom qab polishing txo qis. Vim qhov nce hauv hardness, lub sij hawm polishing yuav tsum tau ua kom qis roughness nce ntxiv. Nyob rau tib lub sij hawm, lub hardness nce, thiab muaj peev xwm ntawm ntau polishing yog correspondingly txo.

3.2 Kev cuam tshuam ntawm qhov chaw ua haujlwm ntawm cov txheej txheem polishing Nyob rau hauv cov txheej txheem crushing ntawm steel txiav machinery, qhov saum npoo yuav raug puas los ntawm tshav kub, nyob rau hauv kev ntxhov siab los yog lwm yam, thiab kev txiav tsis zoo yuav cuam tshuam cov nyhuv polishing. Qhov saum npoo tom qab EDM yog qhov nyuaj rau kev sib tsoo ntau dua li qhov saum npoo tom qab kev ua haujlwm zoo tib yam lossis kev kho cua sov, yog li EDM yuav tsum ua kom zoo-calibrated EDM hnav khaub ncaws ua ntej kawg ntawm EDM, txwv tsis pub lub npoo yuav tsim ib txheej nyias nyias. Yog tias cov txheej txheem kev ua kom zoo EDM tsis raug xaiv kom raug, qhov tob ntawm cov txheej txheem cua sov tuaj yeem ncav cuag qhov siab tshaj plaws ntawm 0.4mm. Lub hardness ntawm hardened nyias txheej yog siab dua li ntawm cov substrate thiab yuav tsum tau muab tshem tawm. Yog li ntawd, nws yog qhov zoo tshaj los ntxiv cov txheej txheem sib tsoo ntxhib, tshem tawm cov txheej txheej puas lawm, thiab tsim ib qho nruab nrab ntxhib hlau nto, muab lub hauv paus zoo rau polishing.

Tshuaj polishing rau polishing yuav tsum tsis yog siab zaus, yuav tsum tau cua sov siv cov cuab yeej tam sim no, yog tias nws muaj peev xwm siv cov saum toj no peb polishing tsis txhob siv tshuaj polishing, vim hais tias cov tshuaj polishing nyhuv tsis zoo, cov nqi them ntau dua.
