1.Mechanical polishing Mechanical polishing inzira yekupukuta inobvisa zvikamu zvakakwenenzverwa zveconvex nekucheka uye deformation yepurasitiki yenzvimbo yezvinhu kuti iwane nzvimbo yakatsetseka.Kazhinji, mitsetse yeoilstone, mavhiri emvere dzemakwai, sandpaper, nezvimwewo zvinoshandiswa, kunyanya mashandiro emaoko, uye zvikamu zvakakosha senge pamusoro pemuviri unotenderera, maturusi ebetsero akadai sematurntable anogona kushandiswa, uye nzira dzekupedzisira-dzakanaka dzekukuya nekupukuta dzinogona kuitwa. inoshandiswa kune zvinodiwa zvemhando yepamusoro.Ultra-chaiyo kugaya uye kukwenenzverwa chinhu chakakosha abrasive chishandiso, icho chinotsikirirwa pamusoro pechigadzirwa chebasa kuti chigadzirwe mumichina yekukuya uye yekupukuta ine abrasive, uye inotenderera nekukurumidza.Uchishandisa tekinoroji iyi, kushata kwepamusoro kweRa0.008μm kunogona kuwanikwa, inova ndiyo yepamusoro-soro pakati penzira dzakasiyana dzekupukuta.Optical lens molds anowanzo shandisa nzira iyi.
Zviripachena kuti mavhiri ehemp anotengeswa nekambani anoshandiswa kurudzi urwu rwekukwenenzverwa, kunyanya kukwenenzvera kwepakati kwesimbi isina tsvina.
2.Chemical polishing Chemical polishing ndeyekubvumira zvikamu zviduku zvishoma zvezvinhu zviri mukati memakemikari kuti zvinyunguduke zvakanyanya pamusoro pezvikamu zveconcave, nokudaro zvichiwana nzvimbo yakatsetseka.Kubatsira kukuru kweiyi nzira ndeyekuti haidi midziyo yakaoma, inogona kupurudzira maworkpieces ane maumbirwo akaomarara, uye inogona kupurudzira akawanda maworkpiece panguva imwe chete, nehunyanzvi hwepamusoro.Dambudziko guru rekupenya kwemakemikari ndiko kugadzirira kwemvura inopenya.Iko kushata kwepamusoro kunowanikwa nekemikari polishing kazhinji yakawanda 10 μm.
3.Electrolytic polishing Nheyo yekutanga ye electrolytic polishing yakafanana neyemakemikari polishing, ndiko kuti, nekusarudza kunyungudutsa zviduku zviduku pamusoro pezvinhu kuti zvigadziriswe.Kuenzaniswa nemakemikari polishing, pesvedzero ye cathode reaction inogona kubviswa, uye mhedzisiro yacho iri nani.Iyo electrochemical polishing process yakakamurwa kuita matanho maviri: (1) Macroscopically flattening zvigadzirwa zvakanyungudutswa uye diffusing mu electrolyte, geometrical roughness pamusoro pechinhu chinodzikira, uye Ra> 1μm.(2) Iyo anodic polarization inobatwa nechiedza chakaderera, uye kupenya kwepamusoro kunovandudzwa, uye Ra.<1μm <br /> 4.In ultrasonic polishing, workpiece inoiswa mu-abrasive suspension uye yakaiswa mumunda we ultrasonic pamwe chete, uye abrasive ivhu uye yakasvibiswa pamusoro pebasa rekushanda ne oscillation ye ultrasonic wave.Iyo macroscopic simba re ultrasonic processing idiki, uye haizokonzeredze deformation yeworkpiece, asi yakaoma kugadzira uye kuisa iyo tooling.Ultrasonic machining inogona kusanganiswa nemakemikari kana electrochemical nzira.Pachikonzero chekugadzirisa corrosion uye electrolysis, ultrasonic vibration inoshandiswa kumutsa mhinduro, kuitira kuti zvigadzirwa zvakanyungudutswa pamusoro pebasa rekushanda zvivharwe, uye gorosi kana electrolyte pedyo nepamusoro yunifomu;iyo cavitation yemafungu e ultrasonic mumvura inogonawo kuvharidzira nzira yekuora, iyo inobatsira kupenya kwepamusoro.
5.Fluid polishing Fluid polishing inovimba ne-high-speed fluid inoyerera uye mabrasive particles anotakurwa nawo kuti akweshe pamusoro pechishandiso kuti azadzise chinangwa chekupenya.Nzira dzinowanzoshandiswa ndeidzi: abrasive jet machining, liquid jet machining, hydrodynamic grinding, etc. Hydrodynamic grinding inotungamirirwa ne hydraulic pressure, kuitira kuti mvura yepakati inotakura mabrasive particles inoyerera ichidzokorora pamusoro pebasa rekushanda nekukurumidza.Iyo yepakati inonyanya kugadzirwa neakakosha makomisheni (polymer-senge zvinhu) ine yakanaka kuyerera pasi pekumanikidzwa kwakadzika uye yakasanganiswa neabrasives, uye mabrasives anogona kuva silicon carbide poda.
6.Magnetic grinding and polishing Magnetic grinding and polishing ndiko kushandiswa kwemagnetic abrasives kuumba mabhurashi abrasive pasi pechiito chemagnetic field kukuya workpieces.Iyi nzira ine hukuru hwekugadzirisa, hutano hwakanaka, kudzora nyore kwekugadzirisa mamiriro uye mamiriro akanaka ekushanda.Nemabrasives akakodzera, kushata kwepamusoro kunogona kusvika kuRa0.1μm.
