Kupukuta kunogona kukamurwa kuita rough polishing, medium polishing, uye fine polishing. Kupukuta kwakashata inzira yekupukuta pamusoro une kana usina hard wheel, iyo ine mhedzisiro yekukuya pa substrate uye inogona kubvisa mavanga akaomarara. Kupukuta kwepakati inzira yekuramba uchigadzirisa nzvimbo dzakaomarara dzakaporishwa uchishandisa mavhiri akaomarara ekupukuta. Inogona kubvisa mavanga anosara nekupukuta kwakashata uye kugadzira pamusoro unopenya zviri pakati nepakati. Kupukuta kwakachena inzira yekupedzisira yekupukuta, uchishandisa soft wheel kupukuta uye kuwana girazi rakapenya. Haina simba guru rekukuya pa substrate.
Ⅰ.Vhiri rekukwesha
Mavhiri ekupolisha anogadzirwa nemachira akasiyana, uye maumbirwo awo anosanganisira zvinotevera:
1. Rudzi rwekusona: Inogadzirwa nekusona zvidimbu zvejira pamwe chete. Nzira dzekusona dzinosanganisira concentric denderedzwa, radial, radial arc, spiral, square, nezvimwewo. Zvichienderana nehuwandu hwakasiyana hwekusona uye machira, mavhiri ekupolisha ane kuoma kwakasiyana anogona kugadzirwa, ayo anonyanya kushandiswa pakupolisha zvisina kunaka.
2. Isina sutured: Ine mhando mbiri: rudzi rwedhisiki nerudzi rwemapapiro. Ose anounganidzwa kuita mavhiri akapfava achishandisa machira, akagadzirirwa kukwesha nemazvo. Mapapiro ane hupenyu hwakareba.
3. Kupeta: Inoumbwa nekupeta zvidimbu zvejira rakatenderera mumachira maviri kana matatu kuti zviite "bhegi", wozozvibatanidza pamusoro peimwe neimwe. Vhiri iri rekupolisha riri nyore kuchengeta zvinhu zvekupolisha, rine kutwasuka kwakanaka, uye rinobatsirawo kuti mhepo itonhorere.
4. Rudzi rwemakwinya: Cheka jira rinoputirwa kuita zvidimbu makumi mana nezvishanu zvakatenderedzwa, wozvisona kuita marongero anoenderera mberi, akarerekera, wobva waputira jira racho uchitenderedza silinda ine mitsetse kuti riite chimiro chakakwenyana. Pakati pevhiri rinogona kuiswa kadhibhodhi kuti vhiri rikwanise kupinda nemuchina. Mavhiri esimbi ane mhepo inofefetera anogonawo kuiswa (chimiro ichi chiri nani). Hunhu hwevhiri iri rinoputirwa ibasa rakanaka rekupukuta kupisa, rakakodzera kupukuta zvikamu zvikuru nekukurumidza.
Ⅱ. Mumiriri wekukwesha
1. Paste yekukwesha
Paste yekupolisha inogadzirwa nekusanganisa abrasive yekupolisha ne namati (senge stearic acid, paraffin, nezvimwewo) uye inogona kutengwa pamusika. Kurongwa kwayo, hunhu, uye mashandisirwo ayo zvinoratidzwa mumufananidzo unotevera.
| Rudzi | Hunhu | Zvinangwa |
| Chinwiwa chekuchenesa chena
| Yakagadzirwa necalcium oxide, magnesium oxide, uye namati, ine zvidimbu zvidiki asi isina kupinza, inogona kudonha kana ikachengetwa kwenguva yakareba. | Kupukuta simbi dzakapfava (aruminiyamu, mhangura, nezvimwewo) nezvinhu zvepurasitiki, zvinoshandiswawo pakupukuta nemazvo |
| Paste yekupukuta tsvuku | Yakagadzirwa nesimbi oxide, chipunu chakasanganiswa, uye chinonamira, nezvimwewo, Kuoma kwepakati | Kupukuta zvikamu zvesimbi zvakajairika, zvearuminiyamu, mhangura nezvimwe zvikamuKukanda zvinhu zvisina kunaka |
| Chinwiwa chekupukuta chegirini | Kushandisa zvinhu zvakaita seFe2O3, alumina, uye zvinonamira zvakagadzirwa nehunyanzvi hwakasimba hwekukuya | Simbi yakaoma yekupolisha, mugwagwa, simbi isina ngura |
2. Mhinduro yekupukuta
Chinhu chinokwesha chinoshandiswa mupurasitiki yekukwesha chakafanana neicho chinoshandiswa mupurasitiki yekukwesha, asi chekutanga chinoshandiswa patembiricha yemukamuri mumafuta emvura kana emulsion yemvura (zvinhu zvinobvira moto hazvifanirwe kushandiswa) kutsiva namati yakasimba mupurasitiki yekukwesha, zvichikonzera mushonga wekukwesha wemvura.
Pakushandisa mushonga wekupukuta, unopfapfaidzwa pavhiri rekupukuta nebhokisi rekupukunyudza rine pressurized, bhokisi rekupukunyudza repamusoro, kana pombi ine spray gun. Kumanikidzwa kwebhokisi rekudyisa kana simba repombi kunoenderana nezvinhu zvakaita sekusimba kwemushonga wekupukuta uye huwandu hunodiwa. Nekuda kwekuwanikwa kwemushonga wekupukuta nguva dzose sezvinodiwa, kupfeka kwevhiri rekupukuta kunogona kuderedzwa. Hazvizosiyi mushonga wekupukuta wakawandisa pamusoro pezvikamu uye zvinogona kuvandudza kushanda zvakanaka kwekugadzira.
