Ukusebenza kweCeramic Alumina Abrasive Particles kungaphuculwa ngokudibanisa i-alumina etyhidiweyo engaphelelanga etyhidiweyo ukwenza amavili abrasive adibeneyo. Ngeli xesha, kuyimfuneko ukwazi ubude be-arc yokusika ivili lokugaya kwi-workpiece, ukwenzela ukuba unqume umlinganiselo wevili lokugaya. I-Silicon carbide: I-SiC abrasive inokwakheka okubukhali ngokwendalo. Ifanelekileukusilaizinto ezinzima (ezifana ne-cemented carbide). Ngenxa yobukhali bayo, ikwalungele ukusetyenzwa kwezinto ezithambileyo kakhulu, ezifana ne-aluminiyam, iipholima, irabha, intsimbi enamandla aphantsi, iialloyi zobhedu kunye neeplastiki.
Idayimani: Zombini iidayimani zendalo kunye nezokwenziwa zingasetyenziselwa ukucola. Idayimani luhlobo lobulukhuni obuphezulu bekhabhoni. Ngenxa yokuba inobudlelwane ne-iron (intsimbi yialloyi yentsimbi kunye nekhabhoni) kwaye yenza ukunxiba okukhawulezileyo, ayifanelekanga.umatshiniizinto ze-ferrous, kodwa idayimane ifaneleka ngokukodwa ekusileni izinto ezingenayo i-ferrous, i-titanium, i-ceramics kunye ne-cermets. I-CBN: Njengedayimani, i-CBN yi-abrasive ebiza kakhulu.
Ixabiso levili le-abrasive super hard hard lingaphezulu kwamaxesha angama-50 ngaphezu kwesondo eliqhelekileyo, kodwa ubomi bayo benkonzo bungaphezulu kwamaxesha angama-100 ngaphezu kwesondo eliqhelekileyo elibi. Nokuba eyona ntsimbi ilukhuni igutyungelwe, igugile nje kancinane. I-CBN yeyona ifanelekileyooomatshinigizinto ezinentsimbi, ngakumbi xa imilo yevili lokugaya ifuneka ukuba igcinwe ixesha elide, njengokusila kwendlela yomjaho ekuthwaleni. Ukongeza, i-CBN ifaneleke ngakumbi kwinkqubo yokutshintshwa kwevili okungaqhelekanga, kuba iibhetshi ezincinci kunye nokutshintshwa kwevili zifuna ukunxiba ngexesha lofakelo, eyona nto iphambili ekhokelela ekusetyenzisweni kwevili.
Ngenxa yokuba i-CBN iya kusabela ngamanzi kwiqondo lokushisa eliphezulu kunye nokukhawuleza ukunxiba, i-ethylene glycol okanye ioli kufuneka isetyenziswe. Ibhondi eqhelekileyoukusilaIvili linokuba yi-ceramic, i-resin okanye iplastiki, ngelixa i-bond ye-abrasive enzima kakhulu inokugqunywa kwivili lokusila nge-matrix yensimbi ene-sintered okanye i-electroplating nickel layer. Olu hlobo lwevili lokusila alungeneli kwaye alunamingxuma.
Iukusilaulwelo lwentsimbi yebhondi kunye nevili lokusila elibizwa ngokuba yi-electroplated liya kukhethwa ngononophelo ukuthintela ukutyibilika kwevili lokusila. Uxinzelelo olukhulu oluguquguqukayo lwehydraulic oluveliswe kwi-arc yokusika ngexesha lokutyibilika luya kuphakamisa ivili lokusila, likhokelela ekuwohlokeni kokugqiba kwesixhobo sokusebenza kunye nokukhawulezisa ukunxiba kwevili lokusila.
