Stainless hlau polishing txoj kev

1.Mechanical polishing Mechanical polishing yog ib txoj kev polishing uas tshem cov polished convex qhov chaw los ntawm kev txiav thiab yas deformation ntawm cov khoom nto kom tau ib tug du nto.Feem ntau, oilstone strips, wool log, sandpaper, thiab lwm yam yog siv, feem ntau yog phau ntawv khiav lag luam, thiab tshwj xeeb qhov chaw xws li lub nto ntawm lub rotating lub cev, auxiliary cuab yeej xws li turntables yuav siv tau, thiab ultra-fine sib tsoo thiab polishing txoj kev yuav ua tau. siv rau cov kev xav tau zoo saum npoo av.Ultra-precision sib tsoo thiab polishing yog ib qho tshwj xeeb abrasive cuab yeej, uas yog nias rau ntawm qhov chaw ntawm lub workpiece yuav tsum machined nyob rau hauv lub sib tsoo thiab polishing kua uas muaj abrasive, thiab rotates ntawm kev kub 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 polishing.Optical lens pwm feem ntau siv txoj kev no.
Obviously cov hemp log muag los ntawm lub tuam txhab yog siv rau hom polishing, feem ntau yog rau nruab nrab polishing ntawm stainless hlau.
2.Chemical polishing Chemical polishing yog tso cai rau lub microscopically protruding qhov chaw ntawm cov khoom nyob rau hauv cov tshuaj nruab nrab kom dissolve preferentially tshaj lub concave qhov chaw, yog li 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 workpieces 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 ob peb 10 μm.
3.Electrolytic polishing Lub hauv paus ntsiab lus ntawm electrolytic polishing yog tib yam li cov tshuaj polishing, uas yog, los ntawm kev xaiv dissolving cov me me protrusions rau saum npoo ntawm cov khoom los ua kom du nto.Piv nrog tshuaj polishing, 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) Macroscopically flattening cov khoom yaj thiab diffusing rau hauv cov electrolyte, geometrical roughness ntawm qhov saum npoo ntawm cov khoom txo, thiab Ra> 1μm.(2) Lub anodic polarization yog flattened los ntawm lub teeb qis, thiab qhov ci ntsa iab zoo tuaj, thiab Ra<1 m.<br /> 4.In ultrasonic polishing, lub workpiece yog muab tso rau hauv lub abrasive ncua kev kawm ntawv thiab muab tso rau hauv lub ultrasonic teb ua ke, thiab cov abrasive yog av thiab polished nyob rau saum npoo ntawm lub workpiece los ntawm oscillation ntawm lub ultrasonic yoj.Lub zog macroscopic ntawm kev ua ultrasonic yog me me, thiab nws yuav tsis ua rau deformation ntawm lub workpiece, tab sis nws yog ib qho nyuaj rau ua thiab nruab cov cuab yeej.Ultrasonic machining tuaj yeem ua ke nrog cov tshuaj los yog electrochemical txoj kev.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 detached, thiab cov corrosion los yog electrolyte nyob ze ntawm lub nto yog uniform;lub cavitation ntawm ultrasonic tsis nyob rau hauv cov kua kuj tuaj yeem cuam tshuam cov txheej txheem corrosion, uas yog qhov zoo rau qhov ci ntsa iab.
5.Fluid polishing Fluid polishing cia siab rau cov kua dej nrawm nrawm thiab cov khoom abrasive nqa los ntawm nws los txhuam qhov chaw ntawm qhov chaw ua haujlwm kom ua tiav lub hom phiaj ntawm polishing.Feem ntau siv txoj kev yog: abrasive dav hlau machining, kua dav hlau machining, hydrodynamic sib tsoo, thiab lwm yam. Hydrodynamic sib tsoo yog tsav los ntawm hydraulic siab, kom cov kua nruab nrab nqa abrasive hais ntws reciprocatingly thoob plaws saum npoo 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 flowability nyob rau hauv qis siab thiab tov nrog abrasives, thiab cov abrasives yuav ua tau silicon carbide hmoov.
6.Magnetic sib tsoo thiab polishing Sib nqus sib tsoo thiab polishing yog siv cov hlau nplaum abrasives los ua cov txhuam txhuam hauv qab qhov kev txiav txim ntawm cov hlau nplaum sib nqus kom zom cov khoom ua haujlwm.Txoj kev no muaj kev ua haujlwm siab, ua haujlwm zoo, tswj tau yooj yim ntawm kev ua haujlwm thiab kev ua haujlwm zoo.Nrog rau qhov tsim nyog abrasives, qhov saum npoo roughness tuaj yeem ncav cuag Ra0.1μm.
