Ivili lokugayaluhlobo lomsebenzi wokusika, luhlobo lwezixhobo zokusika abrasive.Kwivili lokugaya, i-abrasive inomsebenzi ofanayo kunye ne-serrations kwi-saw blade.Kodwa ngokungafaniyo nemela yesarha, enezingxobo kuphela emacaleni, intsimbi yokusila isasazwa kulo lonke ivili.Amawakawaka amasuntswana abrasive ashukunyiswa ngaphaya kwendawo yokusebenza ukususa amasuntswana amancinane ezinto.
Ngokuqhelekileyo abanikezeli be-abrasive baya kubonelela ngeemveliso ezahlukeneyo kwiinkqubo ezahlukeneyo zokusila kwi-metal processing.Ukukhetha imveliso engalunganga kunokubiza ixesha elininzi kunye nemali.Eli phepha libonelela ngemigaqo esisiseko yokukhetha elona vili lokusila.
Abrasive: uhlobo lwesanti
Ivili lokugaya okanye elinye ilitye lokusila elidityanisiweyo linamacandelo amabini aphambili:
Iigrits ezenza ngokwenene ukusika, kunye nokudibanisa okubamba iigrits kunye kunye nokuxhasa i-grits ngelixa ukusika.Ukwakhiwa kwevili lokugaya kunqunywe ngumlinganiselo we-abrasive, i-binder kunye ne-void phakathi kwabo.
Iibrasives ezithile ezisetyenziswe kwivili lokugaya zikhethwa ngokwendlela edibana ngayo nezinto zokusebenza.I-abrasive efanelekileyo yileyo inamandla okuhlala ibukhali kwaye ayikho lula.Xa i-passivation iqala, i-abrasive iya kuphuka ukwenza amanqaku amatsha.Uhlobo ngalunye lwe-abrasive luyingqayizivele, kunye nobunzima obahlukeneyo, amandla, ukuqina kwe-fracture kunye nokumelana nempembelelo.
I-alumina yeyona nto isetyenziswa ngokuqhelekileyo kumavili okusila.
Ngokuqhelekileyo isetyenziselwa ukugaya i-carbon steel, i-alloy steel, i-high speed steel, i-malleable cast iron, isinyithi ekhandiweyo, ubhedu kunye nezinyithi ezifanayo.Kukho iintlobo ezininzi ze-alumina abrasives, nganye eyenziwe ngokukodwa kwaye ixutywe kuhlobo oluthile lomsebenzi wokusila.Uhlobo ngalunye lwe-alumina lunegama lalo: ngokuqhelekileyo ukudibanisa oonobumba kunye namanani.La magama aya kwahluka ukusuka kumenzi ukuya kumenzi.
Zirconia aluminangolunye uchungechunge lwee-abrasives, ezenziwe ngokuxuba i-alumina kunye ne-zirconia ngokwemilinganiselo eyahlukeneyo.Olu luhlu luvelisa i-abrasive eyomeleleyo, ehlala ixesha elide eyenza kakuhle kwizicelo zokusila, njengasemisebenzini yokusika.Kwakhona kusebenza kuzo zonke iintlobo zentsimbi kunye ne-alloy steel.
Njenge-alumina, iintlobo ezininzi ezahlukeneyo ze-zirconia alumina ziyafumaneka.
I-Silicon carbide yenye i-abrasive esetyenziselwa ukucola intsimbi engwevu, intsimbi ebandayo, ubhedu, ubhedu oluthambileyo kunye ne-aluminiyam, kunye nelitye, irabha kunye nezinye iintsimbi ezingenayo i-ferrous.
I-alumina yeCeramicluphuhliso olungundoqo lwamva nje kwinkqubo yokurhabula.Yinkozo esulungekileyo ephezulu eveliswa yinkqubo ye-gel sintering.Oku kurhaxayo kunokwaphula isikali semicron ngesantya esilawulwayo.Ngokulandelayo, amawaka ngamanqaku amatsha ayavela.Iibrasives ze-ceramic alumina zinzima kakhulu kwaye zisetyenziselwa ukugaya okuchanekileyo kwentsimbi.Zihlala zixutywa kunye nezinye iibrasives kwimilinganiselo eyahlukeneyo yokwandisa ukusebenza kwazo kwizinto ezahlukeneyo kunye nokusetyenziswa.
