Stainless simbi pamusorofinishing - polishing classification

1.1Mechanical polishing:Mechanical polishing ndeyekucheka, deformation yepurasitiki yepasi pechinhu kubvisa iyo yakakwenenzverwa convex chikamu uye kuwana yakatsetseka yekupukuta nzira, kazhinji uchishandisa iyo whitetstone tambo, vhiri remvere, sandpaper, nezvimwe, kunyanya mashandiro emaoko, zvikamu zvakakosha senge pamusoro pemuviri unotenderera, unogona kushandisa maturusi ekubatsira senge tafura yekutenderera, nzira yekushongedza yepamusoro inogona kushandiswa yepamusoro. Super finishing polishing ndiko kushandiswa kwezvishandiso zvakakosha zvekukuya, mumvura yekupukuta ine abrasive, yakanyatso kudzvanywa pane workpiece kuti igadziriswe pamusoro, kuitira kutenderera kwepamusoro. Iko kushata kwepamusoro kweRa0.008μm kunogona kuwanikwa nekushandisa tekinoroji iyi, inova ndiyo yepamusoro-soro pakati penzira dzakasiyana dzekupukuta. Iyi nzira inowanzoshandiswa mune optical lens molds.

1.2Kemikari polishing:Kemikari polishing ndeyekunyungudutsa iyo micro-convex chikamu chepamusoro pechinhu muchemikari yepakati zviri nani pane iyo concave chikamu, kuitira kuti uwane nzvimbo yakatsetseka. Kubatsira kukuru kweiyi nzira ndeyekuti haidi midziyo yakaoma, inogona kupuruzira iyo workpiece ine chimiro chakaoma, uye inogona kupurudzira akawanda workpieces panguva imwe chete, ine hunyanzvi hwepamusoro. Dambudziko guru rekupenya kwemakemikari ndiko kugadzirira kwemvura inopenya. Iko kushata kwepamusoro kunowanikwa nemakemikari polishing kazhinji 10μm.

1.3Electrolytic polishing:Nheyo yekutanga yekupenya kwe electrolytic yakafanana nekemikari polishing, ndiko kuti, nekusarudza kunyungudutsa zvidimbu zvidiki zvakabudikira pamusoro pechinhu kuti chitaridzike. Kuenzaniswa nemakemikari polishing, mhedzisiro ye cathode reaction inogona kubviswa uye mhedzisiro yacho iri nani.

Iyo electrochemical polishing process yakakamurwa kuita nhanho mbiri: (1) iyo macro leveling yakanyungudika chigadzirwa chinopararira mu electrolyte, iyo geometric roughness yepasi yezvinhu inodzikira, uye Ra> 1μm. (2) Low light level anodic polarization, kupenya kwepamusoro kwakawedzera, Ra

1.4Ultrasonic polishing:Iyo workpiece inoiswa mu abrasive suspension uye yakaiswa pamwe chete mumunda we ultrasonic, uye abrasive iri pasi uye yakasvibiswa pamusoro pebasa rekushanda kuburikidza nekuvimba ne oscillation ye ultrasonic wave. Ultrasonic processing macroscopic simba idiki, haizokonzeri workpiece deformation, asi tooling kugadzira uye kugadzwa kunonyanya kuoma. Ultrasonic processing inogona kusanganiswa nemakemikari kana electrochemical nzira. Pachikonzero chekugadzirisa corrosion uye electrolysis, ultrasonic vibration inoshandiswa kumutsa mhinduro, kuitira kuti zvigadzirwa zvakanyungudutswa pamusoro pebasa rekushanda zviparadzaniswe, uye gorosi kana electrolyte pedyo nepamusoro yunifomu. Ultrasonic cavitation mumvura inogonawo kudzivisa corrosion process, iyo inobatsira kupenya kwepamusoro.

1.5Fluid polishing: Fluid polishing inovimba nekumhanya-mhanya kwekuyerera kwemvura uye zvimedu zvayo kushambidza pamusoro peiyo workpiece kuzadzisa chinangwa chekupukuta. Nzira dzakajairika ndeidzi: abrasive jet processing, liquid jet processing, hydrodynamic grinding uye zvichingodaro. Kugaya kweHydrodynamic kunofambiswa nehydraulic pressure kuita kuti mvura yepakati inotakura abrasive particles ifambe nepamusoro pe workpiece nekumhanya kukuru. Iyo yepakati inonyanya kugadzirwa nemakomisheni akakosha (polymer-senge zvinhu) ine kuyerera kwakanaka pasi pekumanikidzwa kwakaderera uye yakasanganiswa neabrasives, inogona kuva silicon carbide poda.

1.6Magnetic grinding polishing:Magnetic grinding polishing ndiko kushandiswa kwemagineti abrasives pasi pechiito chemagnetic fields kugadzira brasive brashi kukuya workpiece. Iyi nzira ine zvakanakira kushandiswa kwepamusoro, hutano hwakanaka, kudzora nyore kwekugadzirisa mamiriro uye mamiriro akanaka ekushanda. Iine abrasive yakakodzera, kushata kwepamusoro kunogona kusvika kuRa0.1μm.

Zvinhu zvinokanganisa kunaka kwekupenya kwefa Nekuti iyo mechanic polishing inonyanya kupedzwa nemanyorero, kupenya tekinoroji ichiri chikonzero chikuru chekukanganisa kunaka kwekupenya. Pamusoro pezvo, zvakare ine hukama neiyo mold zvinhu, mamiriro epamusoro asati apenya, uye maitiro ekupisa. Simbi yemhando yepamusoro ndiyo inodiwa kuti pave nekukwenenzverwa kwemhando yepamusoro, kana kuomarara kwesimbi kwepamusoro kusina kuenzana kana paine misiyano yehunhu, kazhinji inoburitsa matambudziko ekupukuta. Yakasiyana-siyana inclusions uye pores musimbi haibatsiri kupukuta.

3.1 Kupesvedzera kwekuomarara kwakasiyana pakukwenenzverwa Kuwedzera kwekuoma kunowedzera kuoma kwekukuya, asi kushata mushure mekupenya kunoderera. Nekuda kwekuwedzera kwekuomarara, nguva yekupukuta inodiwa kuti uwane yakaderera roughness inowedzera zvinoenderana. Panguva imwecheteyo, kuoma kunowedzera, uye mukana wekunyanyisa kupenya kunoderedzwa zvakafanana.

3.2 Kupesvedzera kwe workpiece pamusoro pemamiriro ekugadzirisa maitiro Mukugadzirisa kwekugadzirisa kwesimbi yekucheka michina, nzvimbo yacho ichakuvadzwa nekupisa, kushushikana kwemukati kana zvimwe zvinhu, uye zvipembenene zvisina kukodzera zvekucheka zvichakanganisa maitiro ekugadzirisa. Iyo yekumusoro mushure meEDM yakanyanya kuoma kugaya kupfuura iyo mushure memazuva ese machining kana kupisa kupisa, saka EDM inofanirwa kuve yakanyatso-calibrated EDM kupfeka isati yapera EDM, kana zvisina kudaro iyo nzvimbo ichaita yakaomeswa nhete. Kana iyo EDM yekunatsiridza nzira isina kusarudzwa zvakanaka, kudzika kwekupisa kunokanganisa dhizaini kunogona kusvika pakureba kwe0.4mm. Kuoma kweiyo yakaomeswa yakaonda layer yakakwirira kupfuura iyo ye substrate uye inofanira kubviswa. Naizvozvo, zviri nani kuwedzera rough grinding process, kubvisa zvachose iyo yakakuvadzwa yepasi layer, uye kuumba avhareji rough metal surface, zvichipa hwaro hwakanaka hwekupenya.

Kemikari polishing yezvinodiwa zvekupenya haisi nguva dzakakwirira, inoda kupisa kushandiswa kwemichina yemazuva ano, kana ichikwanisa kushandisa matatu ari pamusoro apa kupukuta usashandisa kemikari yekupenya, nokuti kemikari yekupenya haina kunaka, mutengo wakazara wakakwirira.
