1. Ubulukhuni obuphezulu
Inzuzo ephambili yeamavili okugaya afakwe ngombanebubunzima bazo obuphezulu. Oku kungenxa yokuba i-electroplated metal bond esetyenziselwa ukwenza eli vili idla ngokwenziwa nge-nickel okanye i-nickel-cobalt alloy. Le binder inesakhiwo esixineneyo esiphucula i-bond kunye nobunzima ngokubanzi. Amavili okusila afakwe i-electroplated anika ubunzima obuphezulu kakhulu kune-bronze kunye ne-resin abrasives. Ulwakhiwo oluncinci lwamavili okusila afakwe i-electroplated lunika iingenelo ezingaphaya kobunzima. Xa zisetyenziselwa ukusila, la mavili anika uzinzo olungcono kuba iinkozo zawo ezirhabaxa zinamathele ngokuqinileyo kwi-substrate yesinyithi. Oku kuqinisekisa ukuba ivili lokusila livelisa iziphumo ezifanayo nangona liphantsi koxinzelelo oluphezulu. Ukongeza, olu phawu lunceda ukwandisa ubomi bevili lokusila.
2. Eyona mbobo iphantsi
Enye into eyenza amavili okugaya afakwe ngombane ahluke kwamanye akwiklasi yawo kukuba aneembobo ezisezantsi kunezinye izixhobo ezirhabaxa.
Ukuvuleka kwe-porous sisilinganiso sokuba zingaphi ii-voids ezikhoyo ngaphakathi kwento ethile. Ukuvuleka kwe-porous yevili lokusila kunokuba nefuthe elikhulu ekusebenzeni kakuhle nasekuqineni kwesixhobo. Umzekelo, amavili okusila aqhelekileyo anesinki anokuba nee-porous eziphezulu ukuya kuthi ga kwishumi leepesenti, nto leyo enciphisa ukusebenza kwawo. I-resin okanye i-bronze-bond abrasives nazo zine-porous ephezulu kuneemveliso ezifakwe i-plated.
Kwelinye icala, ubumdaka beevili zokugaya ezifakwe i-electroplated buphantse bube zero. Oku kuzenza zibe zezona zixhobo zixineneyo nezithembekileyo kakhulu kushishino. Ubumdaka obuphantsi beevili zokugaya ezifakwe i-electroplated bukwaluncedo xa kucingwa ngokuqina kwazo. Izixhobo zokugaya ezinamandla aphezulu kunye nozinzo zibalulekile xa kugaywa izinto ezahlukeneyo. Amavili okugaya afakwe i-electroplated phantse awanazo iimbobo kwaye anika amandla aphezulu kunye nozinzo, nto leyo eyenza ukuba zilungele ukusetyenziswa kokugaya okufuna ukuchaneka nokuchaneka. Ngokungafaniyo namavili atshisiweyo, aneembobo ezivulekileyo, amavili afakwe i-electroplated ahlanganiswe ngokupheleleyo ngentsimbi. Oku kuthetha ukuba amasuntswana aqhotyoshelweyo aqhotyoshelweyo aqhotyoshelwe ngqo kwi-substrate yesinyithi. Oku kubangela ukusasazwa okulinganayo kweenkozo eziqhotyoshelweyo kwivili, okwenza ukuba livelise iziphumo ezihambelanayo ngokusetyenziswa ngakunye. Ubumdaka obuphantsi beevili ezifakwe i-plated bukwanceda ekupheliseni iingxaki zokuqhotyoshelwa. Ukuqhotyoshelwa kwenzeka xa ivili linembobo eninzi kakhulu, nto leyo ebangela ukuqokelelana kweenkunkuma eziqhotyoshelwayo ezibizwa ngokuba yi-swarf. Oku kunokuchaphazela kakhulu ukusebenza kwesixhobo. Amavili okugaya afakwe i-electroplated enzelwe ukuthintela ukuqhotyoshelwa ngokubonelela ngebhondi eqinileyo, efanayo, ukuqinisekisa ukuba iitships zisusiwe kumphezulu wokugaya.
3. Eyona ndibaniselwano inamandla
Inzuzo ebalulekileyo yamavili okusila edayimani afakwe ngombane kukunamathelana okuqinileyo phakathi kwesinyithi nezinto ezirhabaxa. Ikhonkco lesinyithi kumaleko okusebenza lifakwe kakhulu kwi-grit, nto leyo eyenza ikhonkco eliqinileyo nelihlala ixesha elide kunezinye iintlobo zamavili. Olu dibaniso luqinisekisa unxibelelwano olufanelekileyo phakathi kwe-abrasive kunye ne-workpiece, nto leyo ekhokelela kwinkqubo yokusila esebenza kakuhle. Ukuhlanganiswa komaleko osebenzayo onamakhonkco esinyithi nako kunamandla, nto leyo ethetha amandla aphezulu okubamba. Lo msebenzi ubalulekile xa kusilwa izixhobo zobunzima obahlukeneyo.
Amavili edayimani afakwe ngombane anokumelana noxinzelelo oluphezulu, nto leyo eyenza ukuba alungele ukugaywa kweentsimbi eziqinileyo ezifana ne-tungsten carbide. Ngenxa yamandla ayo aphezulu okubamba, izinto ezirhabaxa aziyi kuwa ngaphambi kwexesha, nto leyo eyenza ukuba zingabi nakuthelekiswa nokubumba umgubo.
4. Uxinzelelo oluphezulu
Kwiivili zokusila ezenziwe ngomgubo, uxinzelelo olurhabaxa kumaleko okusebenza ngokubanzi luyi-50% ukuya kwi-150%, kwaye umthamo orhabaxa uyi-10% ukuya kwi-30%. Uxinzelelo olurhabaxa lwevili lokusila ledayimani elifakwe ngombane limalunga ne-200%, kwaye umthamo orhabaxa unokufikelela ngaphezulu kwe-65%. Olu xinzelelo luphezulu lwezinto ezirhabaxa luyandisa kakhulu ubomi benkonzo kwaye luphucula ukusebenza okurhabaxa. Uxinzelelo oluphezulu lwezinto ezirhabaxa kumavili okusila edayimani afakwe ngombane lubangelwa yinkqubo yokuvelisa eyahlukileyo.
Xa kuthelekiswa namavili okusila emveli enziwe ngokuxuba iinkozo ezirhabaxa nge-binder aze azicinezele zibe yimo, amavili okusila edayimani afakwe i-electroplated aveliswa ngokusila umaleko weenkozo zedayimani kwi-substrate yesinyithi. Le nkqubo iqinisekisa ukuba amasuntswana edayimani asasazwa ngokulinganayo kwaye anamathele ngokuqinileyo kwi-substrate yesinyithi, nto leyo edala umanyano oluqinileyo ukuze kube nokusebenza kakuhle ngexesha lokusila.
Ukongeza kwezi zibonelelo zine, amavili okugaya edayimani afakwe ngombane anezinye izibonelelo ezininzi.
Okokuqala, zihlala ixesha elide kakhulu kwaye ziyakwazi ukumelana namaqondo obushushu aphezulu kunye noxinzelelo ngaphandle kokulahlekelwa bubuhle okanye imo yazo. Zikwabonelela ngomphezulu wokugaya ococekileyo nochanekileyo, nto leyo ezenza zibe zizixhobo ezifanelekileyo zokusetyenziswa koomatshini abachanekileyo. Enye inzuzo yamavili okugaya edayimani afakwe ngombane kukuguquguquka kwawo. Zingasetyenziswa kwizinto ezahlukeneyo, kuquka izinto eziqinileyo ezifana ne-tungsten carbide kunye ne-ceramics. Oku kuguquguquka kuzenza zibe lukhetho oludumileyo kumashishini aliqela kuquka iimoto, i-aerospace, kunye ne-elektroniki.
