Muaj ntau txoj hauv kev kom ua tiav Daim iav ua rau CNC machining qhov chaw!

Kev ua daim iav hais txog kev ua tiav ntawm qhov chaw tuaj yeem cuam tshuam cov duab zoo li daim iav, qib no tau mus txog qhov chaw ua haujlwm zoo heev, daim iav ua tsis tau tsuas yog tsim lub siab "zoo li theem" ​​rau cov khoom, tab sis kuj txo qhov sib txawv. , ua kom ntev lub neej qaug zog ntawm lub workpiece; Nws yog qhov tseem ceeb hauv ntau lub rooj sib txoos thiab kev sib khi.Thaum xaiv cov txheej txheem polishing rau cov hlau ua haujlwm, cov txheej txheem sib txawv tuaj yeem xaiv raws li qhov xav tau sib txawv.Cov hauv qab no yog ob peb txoj hauv kev ntawm polishing daim iav ua tshuab.

1, mechanical polishing, mechanical polishing yog cia siab rau kev txiav, deformation yas deformation tom qab tshem tawm los ntawm polishing lub convex ib feem ntawm tus nto polishing txoj kev, feem ntau siv cov khoom siv roj pob zeb, wool log, abrasive ntawv, thiab lwm yam. qhov tseem ceeb rau, cov khoom tshwj xeeb xws li nto ntawm cov khoom ntawm lub kiv puag ncig, tuaj yeem siv cov cuab yeej xws li turntable, qhov zoo ntawm qhov zoo tuaj yeem siv los ntawm txoj kev lapping.Super-zoo sib tsoo thiab polishing yog ua los ntawm cov cuab yeej tshwj xeeb abrasive.Nyob rau hauv kev sib tsoo thiab polishing kua uas muaj cov ntaub ntawv abrasive, lub workpiece yog nias nruj nreem rau ntawm qhov chaw machined kom muaj kev kub ceev rotating motion.Qhov roughness ntawm RA0.008μm tuaj yeem ua tiav los ntawm kev siv cov txheej txheem no, uas yog qhov siab tshaj ntawm ntau yam polishing txoj kev. .Txoj kev no feem ntau yog siv rau hauv optical lens pwm.
2, chemical polishing chemical polishing yog ua kom cov khoom siv nyob rau hauv cov tshuaj nruab nrab ntawm qhov chaw microscopic convex ntawm lub concave ib feem ntawm qhov tseem ceeb rau yaj, thiaj li kom tau ib tug du nto.Lub ntsiab kom zoo dua ntawm txoj kev no yog tias nws tsis xav tau complex. Cov khoom siv, tuaj yeem polish lub workpiece ntawm cov duab nyuaj, tuaj yeem polish ntau lub workpiece tib lub sijhawm, kev ua haujlwm siab.Qhov teeb meem tseem ceeb ntawm cov tshuaj polishing yog kev npaj cov kua dej polishing.Qhov roughness tau los ntawm tshuaj polishing feem ntau yog 10μm.
3. Electrolytic polishing Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li cov tshuaj polishing, uas nyob ntawm qhov kev xaiv ntawm kev sib cais ntawm cov me me protrusions ntawm cov khoom siv los ua kom lub ntsej muag du.Piv rau cov tshuaj polishing, cov nyhuv cathodic. Cov tshuaj tiv thaiv tuaj yeem raug tshem tawm thiab cov nyhuv zoo dua.Electrochemical polishing txheej txheem muab faib ua ob kauj ruam1) macro leveling tov diffuses rau hauv electrolyte, thiab geometrical roughness ntawm cov khoom nto txo, RA> 1 microns.
4, Hawker tuaj yeem tsom iav cov khoom siv
Raws li lub tshuab polishing tshiab, nws muaj qhov tshwj xeeb zoo hauv ntau hom hlau ua haujlwm.Nws tuaj yeem hloov cov tsoos sib tsoo tshuab, dov tshuab, tho txawv tshuab, honing, polishing tshuab, xuab zeb siv tshuab thiab lwm yam hlau nto xov thiab tshuab; Kev ua tiav ntawm cov hlau ua haujlwm ua haujlwm yooj yim.Hawker lub zog tuaj yeem tsis tsuas yog polished, tab sis kuj coj tau ntau cov txiaj ntsig ntxiv: nws tuaj yeem txhim kho qhov ua tiav ntawm cov txheej txheem ua haujlwm los ntawm ntau dua 3 qib (roughness Ra tus nqi tau yooj yim mus txog. Hauv qab 0.2); Thiab qhov saum npoo microhardness ntawm lub workpiece yog nce los ntawm ntau tshaj 20%; Lub nto hnav tsis kam thiab corrosion kuj ntawm lub workpiece yog heev txhim khu kev qha. Hawker yuav siv tau los nrog ntau yam stainless hlau thiab lwm yam hlau workpiece.
5, ultrasonic polishing workpiece mus rau hauv lub abrasive ncua kev kawm ntawv thiab muab tso ua ke nyob rau hauv lub ultrasonic teb, cia siab rau lub oscillating nyhuv ntawm ultrasonic, abrasive sib tsoo thiab polishing nyob rau saum npoo ntawm lub workpiece. workpiece, tab sis nws yog ib qho nyuaj rau ua thiab nruab lub tooling.Ultrasonic machining yuav ua ke nrog tshuaj los yog electrochemical txoj kev.Rau lub hauv paus ntawm kev daws corrosion thiab electrolysis, ultrasonic vibration yog thov mus do cov tshuaj, kom cov khoom yaj nyob rau saum npoo. ntawm lub workpiece yog sib cais, thiab cov corrosion los yog electrolyte nyob ze ntawm qhov chaw yog uniform.Ultrasonic cavitation nyob rau hauv cov kua kuj inhibit cov txheej txheem corrosion, uas yog conducive rau saum npoo teeb pom kev zoo.
6, kua polishing kua polishing yog los ntawm kev cia siab rau cov kua dej ceev ceev thiab cov khoom abrasive nqa los ntawm kev yaig ntawm qhov chaw ua haujlwm kom ua tiav lub hom phiaj ntawm polishing. Feem ntau siv txoj kev yog: abrasive dav hlau ua, kua dav hlau ua, kua. lub zog sib tsoo, thiab lwm yam.Hydrodynamic sib tsoo yog tsav los ntawm hydraulic siab, uas ua rau cov kua nruab nrab nqa cov khoom abrasive ntws los ntawm workpiece nto ntawm kev kub ceev.Qhov nruab nrab yog tsim los ntawm cov sib xyaw tshwj xeeb nrog cov fluidity zoo nyob rau hauv qis siab (polymer khoom) thiab sib tov. nrog abrasive, uas tuaj yeem ua los ntawm silicon carbide hmoov.
7, daim iav polishing daim iav polishing, sib nqus polishing sib nqus sib nqus polishing yog siv cov hlau nplaum abrasive nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb los ua ib tug txhuam txhuam, lub workpiece sib tsoo processing.Qhov no muaj qhov zoo ntawm kev ua haujlwm siab, zoo zoo, yooj yim. Kev tswj ntawm kev ua haujlwm thiab kev ua haujlwm zoo.With tsim abrasive, qhov roughness ntawm qhov chaw tuaj yeem ncav cuag Ra0.1μm.Qhov polishing tau hais nyob rau hauv cov yas pwm ua thiab lwm yam lag luam yuav tsum tau polishing nto yog txawv heev, nruj me ntsis hais lus, polishing ntawm pwm yuav tsum yog hu ua daim iav ua.Nws muaj cov kev xav tau siab tsis yog rau polishing nws tus kheej xwb tab sis kuj rau qhov smoothness, smoothness thiab geometric raug.Nto polishing feem ntau yuav tsum tsuas yog ib tug ci ntsa iab nto.Tus qauv ntawm daim iav ua yog muab faib ua plaub theem: AO = RA0. 008μm, A1 = RA0.016μm, A3 = RA0.032μm, A4 = RA0.063μm.Vim tias cov txheej txheem xws li electropolishing thiab kua polishing yog qhov nyuaj rau kev tswj cov geometric raug ntawm qhov chaw, thiab qhov zoo ntawm cov tshuaj polishing, ultrasonic polishing, sib nqus sib tsoo polishing thiab lwm txoj kev tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, yog li daim iav ua ntawm precision pwm. feem ntau yog mechanical polishing.
