Simbi isina tsvina ine zvinhu zvakawanda zvinoita kuti inakidze kune dzakasiyana siyana dzekushandisa, asi zvimiro zvakafanana izvi zvinogona kuita kuti zviome kushanda nazvo.Panguva yekushandiswa, inokwenywa nyore nyore uye yakasvibiswa, ichiita kuti iite ngura.Chekupedzisira asi chisiri chidiki, inodhura kupfuura kabhoni simbi, saka nyaya yemutengo wezvinhu inowedzera kana simbi isina tsvina inogadzirwa.
Vatengi zvakare vane tarisiro huru yemhando yekupedzisa, ichida inenge girazi-sekupedzisa kwechinhu icho nechimiro chayo chinozoratidzwa sechigadzirwa chakapedzwa.Pane mukana mudiki wekuvanza chikanganiso nekupfeka kana pendi.
Paunenge uchishanda nemapombi esimbi isina tsvina, matambudziko aya anowedzera kune imwe nhanho, sezvo kusarudzwa kwezvishandiso zvakakwana uye zvinobudirira zvekugadzirisa zvinhu zviri nyore kusvika pakupedzisa zvishoma.
Nekuda kwekupokana kwayo necorrosion, simbi isina tsvina yakanakira maapplication ayo anoda echisikigo sheen yesimbi, senge mavhiri ekufambisa nemaoko.Izvi zvinoreva zvakare kuti dhayamita yekunze yechubhu inogona kusiyanisa kubva kune chando kusvika kune yakatsetseka, isina chitarisiko.
Izvi zvinoda chishandiso chakakodzera chakasanganiswa neabrasive chaiyo.Kazhinji mubvunzo wekutanga watinobvunza vatengi vedu ndewekudyara kwavanoda kuita kuti vaone kuti vanowana pombi yavanoda kupera nekukurumidza uye nguva dzose.Kune avo vanoda kuchengetedza kuyerera kwakadzikama kwepombi yekupedzisa maodha, otomatiki maitiro necenterless grinder, cylindrical grinder, kana imwe mhando yemuchina webhandi zvinogona kuita kuti zvive nyore kuronga zvikamu kuti uwane mhedzisiro yaunoda.Yakapedzwa kugadzikana kwechigadzirwa kunogonawo kuwanikwa kubva kune chikamu kusvika kune chikamu.
Zvisinei, kunewo zvingasarudzwa zvezvishandiso zvemaoko.Zvichienderana nehukuru hwepombi, bhanhire grinder inogona kuva nzira inobatsira yekuona kuti chikamu chejometri hachishanduki panguva yekupedzisa.Iko kushandiswa kwebhandi slack kunobvumira iyo tubular mbiri kuti ishande isina kuibata kumeso.Mamwe mabhanhire ane matatu anobata pulleys, achibvumira kushanduka kwakawanda kutenderedza chubhu.Mabhandi anowanikwa muhukuru hwakasiyana.Mabhendi emafaira anotangira pa18″ kusvika pa24″, ukuwo King-Boa achida 60″ kusvika 90″ mabhendi.Mabhandi asina pakati uye cylindrical anogona kureba 132 inches kana kureba uye anosvika 6 inches paupamhi.
Dambudziko rezvishandiso zvemaoko nderokuti kuwana kupedzisa kwepamusoro nguva nenguva kune unyanzvi kupfuura sainzi.Vashandi vane ruzivo vanogona kupedzisa kupedzisa nehunyanzvi uhu, asi zvinoda kudzidzira.Kazhinji, kumhanya kwepamusoro kunoguma nekukwenya kwakanaka, nepo kuderera kunokonzeresa kukwenya kwakadzika.Kuwana chiyero kune rimwe basa kunoenderana nemushandisi.Iyo yakakurudzirwa tepi yekutanga kumhanya inoenderana neinodiwa yekupedzisira poindi.
Zvisinei, zvakakosha kudzivisa kushandiswa kwe disc kana grinders yemaoko emhando ipi zvayo yekugadzirisa mapaipi.Zvakaoma kuwana pateni yaunoda nemidziyo iyi, uye kana ukasundira dial zvakanyanya, zvinogona kukanganisa geometry uye kugadzira nzvimbo yakati sandara papombi.Muruoko rwerudyi, kana chinangwa chiri chekupukuta girazi pamusoro pepamusoro pane scratch pattern, matanho akawanda ejecha achashandiswa uye danho rekupedzisira richava jira rekupukuta kana danda rekupukuta.
Kusarudzwa kweabrasive kunoda kunzwisisa kwakajeka kwekupedzisa kwekupedzisira.Chokwadi, izvi zviri nyore kutaura pane kuzviita.Kuongorora kwekuona kunowanzo shandiswa kuenzanisa zvikamu nezvigadzirwa zviripo.Nekudaro, iyo shop abrasive mutengesi inogona kubatsira kuona nzira yekudzikisa zvishoma nezvishoma huwandu hweabrasive kuti uwane mhedzisiro yaunoda.
Paunenge uchikuya simbi isina tsvina kusvika kumusoro kwekupedzisira, zvakakosha kushandisa nhanho inotsika abrasive process.Pakutanga, iwe unoda kuve nechokwadi chekuti mavara ese uye dents zvabviswa.Tinoda kutanga nechigadzirwa chakanakisa kugadzirisa zvikanganiso izvi;iyo yakadzika kukwenya, basa rakawanda rinodiwa kuti rigadzirise.Pane imwe neimwe inotevera nhanho, kutarisirwa kunofanira kutorwa kubvisa mavanga kubva kune yakapfuura abrasive.Nokudaro, yunifomu yekukwenya maitiro inowanikwa pane yakapedzwa chigadzirwa.
Nemaabrasive echinyakare akavharidzirwa, zvinogona kunetsa kusvetuka mamakisi eabrasive kuti uwane iyo chaiyo matte kupera pasimbi isina simbi nekuda kwekuparara kweabrasive.Nekudaro, mamwe matekinoroji anokubvumidza kuti usvetuke matanho, akadai se3M's Trizact abrasives, anopfeka nenzira yekuti abrasive "inozorodzwa" nezviyo zvitsva zviri pachena sezvazviri kushandiswa.3M
Ehe, kuona chiyero chekukasharara kweabrasive zvinoenderana nechinhu.Kana iwe uchida kubvisa kukanganisa kwakadai sekero, dents kana kukwenya kwakadzika, unozofanirwa kushandisa coarse abrasive.Semuenzaniso, isu tinowanzo tanga ne 3M 984F kana 947A conveyor bhandi.Patakangotamira kumabhandi 80 egrit, takachinjira kune mamwe mabhandi ehunyanzvi.
Paunenge uchishandisa zvechinyakare zvakavharwa mabrasives, ita shuwa kuti wadzikisa gradation yeabrasive yega yega pasina kuipotsa nekuda kweiyo abrasive inoputsika kuti uwane iyo chaiyo matte kupera pasimbi isina tsvina.Kana iyo abrasive ikaputsika, kudzvanywa kwakawanda kunodiwa kuti uwane mhedzisiro yakafanana nemaminerari anosviba kana kubviswa kubva kune abrasive.Matte minerals kana masimba epamusoro anogadzira kupisa.Nokuti kupisa idambudziko pakupedzisa simbi isina tsvina, inogona kukanganisa kupera uye "bhuruu" pamusoro.
Imwe nyaya inogona kumuka nemamwe mabrasives akachipa ndeyekuenderana kwekupedza kwavo zvicherwa.Zvichanetsa kune asina ruzivo mushandisi kuona kuti iyo abrasive inowana inodiwa nzvimbo padanho rega rega.Kana paine kusawirirana, zvikwambo zvemusango zvinogona kuoneka zvisingaonekwe kusvika padanho rekupolisha.
Nekudaro, dzimwe nzira dzinokutendera kuti usvetuke matanho.Semuyenzaniso, 3M's Trizact Abrasive inoshandisa musanganiswa weresin uye abrasive kugadzira piramidi chimiro chinovandudza nzvimbo inoputika nezvikamu zvichangobuda pachena kunyange sekupfeka kunoita abrasive.Iyi tekinoroji inovimbisa kupera kunoenderana muhupenyu hwebhanhire.Nekuti giredhi rega rega reTrizact tepi rinopa kupera kunofungidzirwa, takakwanisa kusvetukira mamakisi abrasive mukupera kwekupedzisira.Izvi zvinochengetedza nguva nekudzikisira nhanho dzejecha uye kuderedza rework nekuda kwekusakwana kwejecha.
Kiyi pakusarudza abrasive kuona kuti ungawana sei kupedzisa kwakaringana munguva yakawanda uye nemutengo unoshanda.
Sezvo simbi isina tsvina chinhu chakaoma, kusarudzwa kweabrasive uye minerals inokosha zvikuru.Paunenge uchishandisa abrasive isiriyo, iyo nguva yakareba iyo inogadziriswa, iyo inowedzera kupisa kunogadzirwa.Izvo zvakakosha kushandisa iyo chaiyo mhando yemaminerari uye kushandisa abrasive ine kupisa inobvisa coating kubvisa kupisa kubva kunzvimbo yekusangana kana sanding.
Kana iwe uri kushandisa muchina, unogona zvakare kushandisa chikamu chinotonhorera, icho chinobatsirawo kubvisa marara, kuve nechokwadi chekuti marara anokwenya haakuvadze pamusoro.Iva nechokwadi chekushandisa sefa chaiyo kuitira kuti marara asapinde zvakare kana chinotonhodza chichitenderedzwa mumushini.
Vanhu vazhinji vanofunga kuti simbi yese isina tsvina inotaridzika zvakafanana, asi kana zvasvika kune yakapedzwa pamusoro pechikamu, marudzi maviri akasiyana emaminerari anogona kukanganisa kutaridzika kwechikamu ichocho.Maonero aya anoenderana nemushandisi.
Semuyenzaniso, yechinyakare silicon carbide inowanzosiya yakadzama makwara anoratidza chiedza zvakasiyana uye oita bhuruu.
Panguva imwecheteyo, yechinyakare aluminium oxide inosiya chimiro chakatenderedzwa chinoratidza chiedza zvakasiyana uye chinoita kuti zvinhu zviyero.
Zvichienderana nehukuru hwepombi, bhanhire grinder inogona kuva nzira inobatsira yekuona kuti chikamu chejometri hachishanduki panguva yekupedzisa.Iko kushandiswa kwebhandi slack kunobvumira iyo tubular mbiri kuti ishande isina kuibata kumeso.3M
Kuziva kupera kunodiwa kwechikamu kwakakosha nekuti zvikumbiro zvinowanzoda zvikamu zvitsva kuti zvienderane nezviripo.
Simbi isina tsvina chinhu chinodhura, saka kunyatsosarudzwa kwekupedzisa zvishandiso kwakakosha.Tsigiro yakakodzera kubva kune vatengesi inogona kubatsira zvitoro kutsvaga nzira dzekuchengetedza nguva nemari.
