Simbi isina ngura ine zvinhu zvakawanda zvinoita kuti ikwezve kushandiswa kwakasiyana-siyana, asi zvinhu izvi zvinogona kuita kuti zviome kushanda nayo. Painoshandiswa, inokwenywa nyore nyore uye inosvibiswa, zvichiita kuti ive nyore kukuvadzwa nengura. Chekupedzisira asi chisiri chidiki, inodhura kupfuura simbi yekabhoni, saka nyaya yemutengo wezvinhu inowedzera kana zvikamu zvesimbi isina ngura zvichigadzirwa.
Vatengi vane tarisiro yakakura pamusoro pemhando yependi, vachida kuti chinhu chakagadzirwa chiite segirazi. Pane mukana mudiki wekuvanza chikanganiso nekupenda kana kupenta.
Pakushanda nemapombi esimbi isina ngura, matambudziko aya anowedzera kusvika pamwero wakati, sezvo kusarudzwa kwezvishandiso zvakanakisisa uye zvinoshanda zvekugadzirisa zvinhu zviri nyore kusvika pakupedzisa kwakaganhurirwa.
Nekuda kwekusaora kwayo, simbi isingatsvedzeri yakanakira kushandiswa kunoda kupenya kwechisikigo kwesimbi, senge mavhiri ekudhiraivha nezvombo. Izvi zvinorevawo kuti dhayamita yekunze yechubhu inogona kusiyana kubva pakusviba kusvika pakutaridzika kwakapfava, kusina matambudziko.
Izvi zvinoda chishandiso chakakodzera pamwe chete neabrasive chaiyo. Kazhinji mubvunzo wekutanga watinobvunza vatengi vedu ndewekuti vanoda kuisa marii kuti vave nechokwadi chekuti vanowana pombi inodiwa nekukurumidza uye nguva dzose. Kune avo vanoda kuchengetedza kufamba kwakasimba kwemirairo yekupedzisa pombi, kuita otomatiki maitiro acho ne grinder isina pakati, cylindrical grinder, kana imwe mhando yemuchina webhandi kunogona kuita kuti zvive nyore kuronga zvikamu kuti zviwane mhedzisiro yaunoda. Kugadzikana kwechigadzirwa chakapedzwa kunogonawo kuwanikwa kubva pachikamu kuenda kune chimwe.
Zvisinei, kunewo dzimwe nzira dzekushandisa pamaoko. Zvichienderana nehukuru hwepombi, grinder yebhandi inogona kuva nzira inoshanda yekuona kuti chimiro chechikamu hachichinje panguva yekupedzisa. Kushandiswa kwebhandi rinoita kuti chimiro chebhandi chishande pasina kuribata. Mamwe mabhandi ane mapuru matatu ekubata, zvichibvumira kuchinjika kwakanyanya kutenderedza chubhu. Mabhandi anowanikwa muhukuru hwakasiyana. Mabhandi emafaira anotangira pa18″ kusvika 24″, nepo King-Boa ichida mabhandi e60″ kusvika 90″. Mabhandi asina pakati uye ecylindrical anogona kunge akareba masendimita 132 kana kupfuura uye anosvika masendimita matanhatu paupamhi.
Dambudziko nematurusi emaoko nderekuti kuwana magumo akakodzera kakawanda inyanzvi kupfuura sainzi. Vashandi vane ruzivo vanogona kuwana magumo akanaka nehunyanzvi uhwu, asi zvinoda kudzidzira. Kazhinji, kumhanya kwakakwirira kunokonzera kukwenya kudiki, nepo kumhanya kwakaderera kuchikonzera kukwenya kwakadzama. Kuwana chiyero chebasa rakati zvinoenderana nemushandisi. Kumhanya kwekutanga kwetepi kunokurudzirwa kunoenderana nepokugumira kwaunoda.
Zvisinei, zvakakosha kudzivisa kushandisa madhisiki kana magrinder emhando ipi zvayo pakugadzirisa mapaipi. Zvakaoma kuwana patani yaunoda nezvishandiso izvi, uye kana ukasunda dial zvakanyanya, zvinogona kukanganisa geometry uye kugadzira nzvimbo yakati sandara papombi. Muruoko rwerudyi, kana chinangwa chiri chekupukuta pamusoro pegirazi pane patani yekukwenya, matanho mazhinji ekukwenya achashandiswa uye danho rekupedzisira richava rekugadzira pombi yekukwenya kana stick yekukwenya.
Kusarudza abrasive kunoda kunzwisisa kwakajeka kwekupedzisa kwekupedzisira. Ehe, izvi zviri nyore kutaura pane kuzviita. Kuongorora kwemaziso kunowanzo shandiswa kuenzanisa zvikamu nezvigadzirwa zviripo. Zvisinei, mutengesi we abrasive muchitoro anogona kubatsira kuona kuti ndeapi nzira yakanakisisa yekuderedza zvishoma nezvishoma huwandu hwe abrasive kuti uwane mhedzisiro yaunoda.
Pakukuya simbi isingatsvi kusvika pamusoro pekupedzisira, zvakakosha kushandisa nzira yekukwenya nhanho-nhanho. Pakutanga, unoda kuva nechokwadi chekuti mavara ese nemaburi zvabviswa. Tinoda kutanga nechigadzirwa chakanakisa kugadzirisa zvikanganiso izvi; kana kukwenya kwacho kwakadzika, ndipo panodiwa basa rakawanda kuti chigadziriswe. Padanho rega rega rinotevera, kungwarira kunofanira kutorwa kubvisa mavanga kubva paabrasive yapfuura. Saka, patani yekukwenya yakafanana inowanikwa pachigadzirwa chapera.
Nekushandisa mabrasives akapendwa nesimbi, zvinogona kuoma kusvetuka magiredhi ekukwesha kuti uwane magumo akakodzera esimbi isingatsvedzereki nekuda kwenzira iyo abrasive inoputsika nayo. Zvisinei, mamwe matekinoroji anokubvumidza kusvetuka matanho, akadai se3M's Trizact abrasives, ayo anopfekwa nenzira yekuti abrasive "inovandudzwa" netsanga itsva dzakaburitswa padzinoshandiswa. 3M
Ehe, kuona mwero wekuoma kwechinhu chinokwesha chinoenderana nechinhu chacho. Kana uchida kubvisa zvikanganiso zvakaita sechikero, maburi kana mavanga akadzika, uchafanira kushandisa chinhu chinokwesha chinokanganisa. Semuenzaniso, tinowanzo tanga nebhandi re3M 984F kana 947A. Patakanga tava nemabhandi egrit 80, takachinja kuenda kune mamwe mabhandi ane hunyanzvi.
Kana uchishandisa mabrasives akapendwa echinyakare, iva nechokwadi chekuti waderedza kukwira kwebrasive yega yega usingaipotse nekuda kwekuti abrasive inoputsika sei kuti iwane matte finish chaiyo pasimbi isingatsvedzeri. Kana abrasive yaputsika, kumanikidzwa kwakawanda kunodiwa kuti uwane mhedzisiro yakafanana neyakaita maminerals inosviba kana kuti inobviswa kubva pabrasive. Matte minerals kana simba rakakwirira rinogadzira kupisa. Nekuti kupisa idambudziko pakupedzisa simbi isingatsvedzi, zvinogona kukanganisa kupedzisa uye "kusviba" pamusoro.
Chimwe chinhu chinogona kuitika kana paine mamwe mabrasive akachipa ndiko kuti mamineral awo anogadzirwa zvakanaka. Zvichaomera munhu asina ruzivo kuti ave nechokwadi chekuti abrasive yacho yawana nzvimbo yaanoda padanho rega rega. Kana paine kusawirirana, mavanga emusango anogona kuonekwa asingaonekwe kusvika padanho rekukwesha.
Zvisinei, dzimwe nzira dzinokubvumira kusvetuka matanho. Semuenzaniso, Trizact Abrasive ye3M inoshandisa musanganiswa we resin ne abrasive kugadzira chimiro chepiramidhi chinovandudza pamusoro pe abrasive nezvidimbu zvitsva zvakabuda pachena kunyangwe abrasive ichipera. Iyi tekinoroji inovimbisa kupedzisa kwakafanana muhupenyu hwese hwebhandi. Nekuti giredhi rega rega reTrizact tepi rinopa kupedzisa kunogoneka, takakwanisa kusvetuka magiredhi abrasive mukupedzisa kwekupedzisira. Izvi zvinoponesa nguva nekuderedza matanho ekusenda uye kuderedza kugadziriswa nekuda kwekusenda kusina kukwana.
Chinhu chikuru pakusarudza abrasive ndechekuona kuti ungapedza sei zvakanaka munguva pfupi uye nenzira inoshanda.
Sezvo simbi isingatsvi iri chinhu chakaoma, kusarudza zvinogumbura nezvicherwa kwakakosha zvikuru. Pakushandisa zvinogumbura zvisiri izvo, kana zvinhu zvichigadziriswa kwenguva yakareba, ndipo panobva pagadzirwa kupisa kwakawanda. Zvakakosha kushandisa mhando chaiyo yemineral uye kushandisa zvinogumbura zvine coating inopisa kubvisa kupisa kubva panzvimbo yekubatana paunenge uchiisa sandpaper.
Kana uri kushandisa muchina, unogona zvakare kushandisa chikamu chinotonhodza, icho chinobatsirawo kubvisa marara, zvichiita kuti marara asakuvadze pamusoro. Iva nechokwadi chekuti washandisa sefa yakakodzera kuitira kuti marara asadzoke kana chinhu chinotonhodza chadzoserwa mumuchina.
Vanhu vazhinji vanofunga kuti simbi yese isingatsvi inotaridzika zvakafanana, asi kana zvasvika pamusoro pechinhu chakapedzwa, mhando mbiri dzakasiyana dzezvicherwa dzinogona kukanganisa chitarisiko chechikamu ichocho. Maonero aya anoenderana nemushandisi.
Semuenzaniso, silicon carbide yechinyakare inowanzosiya mavanga akadzika anoratidza chiedza zvakasiyana uye inoita kuti ive yebhuruu.
Panguva imwe chete, aluminium oxide yechinyakare inosiya chimiro chakatenderera chinoratidza chiedza zvakasiyana uye chinoita kuti chinhu chacho chive cheyero.
Zvichienderana nehukuru hwepombi, muchina wekukuya bhandi unogona kuva nzira inoshanda yekuona kuti chimiro chechikamu hachichinje panguva yekupedzisa. Kushandisa bhandi rinoita kuti bhandi rishande pasina kuribata. 3M
Kuziva kupedzisa kunodiwa kwechikamu kwakakosha nekuti maapplication anowanzo da zvikamu zvitsva kuti zvienderane nezviripo.
Simbi isina ngura chinhu chinodhura, saka kusarudza maturusi ekupedzisa nekungwarira kwakakosha. Rutsigiro rwakakodzera kubva kuvatengesi runogona kubatsira zvitoro kuwana nzira dzekuchengetedza nguva nemari.
