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 ezahlukeneyo 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 lwamva nje olungundoqo kwinkqubo yokukrala. Yinkozo ecocekileyo eveliswa yinkqubo ye-gel sintering. Oku kurhaxa kunokwaphula isikali semicron ngesantya esilawulwayo. Ngokulandelayo, amawaka amanqaku amatsha ayavela. Iibrasives ze-alumina ze-Ceramic zinzima kakhulu kwaye zisetyenziselwa ukugaya okuchanekileyo kwentsimbi. Zihlala zixutywa kunye nezinye iibrasives kwimilinganiselo eyahlukeneyo yokwandisa ukusebenza kwazo kwizinto ezahlukeneyo kunye nokusetyenziswa.
