Lebili la ho sila kapa lejoe le leng le kopaneng la ho sila le na le likarolo tse peli tsa mantlha:
Li-grits tse hlileng li etsang ho itšeha, le motsoako o tšoarang li-grits hammoho le ho tšehetsa li-grits ha li ntse li khaola.Sebopeho sa lebili la ho sila se khethoa ke karo-karolelano ea abrasive, binder le lefeela pakeng tsa tsona.
Li-abrasives tse khethehileng tse sebelisoang lebiling la ho sila li khethoa ho latela tsela eo li sebelisanang ka eona le lisebelisoa tsa mosebetsi.The abrasive e loketseng ke e nang le bokhoni ba ho lula e le bohale 'me e sa foufale habonolo.Ha passivation e qala, abrasive e tla robeha ho theha lintlha tse ncha.Mofuta o mong le o mong oa abrasive o ikhethile, o na le boima bo fapaneng, matla, ho tiea ha fracture le ho hanyetsa tšusumetso.
Alumina ke abrasive e sebelisoang ka ho fetisisa mabiling a silang.
Hangata e sebelisoa ho sila tšepe ea carbon, alloy iron, high speed steel, malleable cast iron, tšepe e betliloeng, boronse le litšepe tse tšoanang.Ho na le mefuta e mengata e fapaneng ea li-abrasives tsa alumina, e 'ngoe le e' ngoe e entsoe ka ho khetheha le ho kopanngoa bakeng sa mofuta o itseng oa ts'ebetso ea ho sila.Mofuta o mong le o mong oa alumina o na le lebitso la oona: hangata ke motsoako oa litlhaku le linomoro.Mabitso ana a tla fapana ho ea ka moetsi ho ea ho moetsi.
Zirconia aluminake letoto le leng la li-abrasives, tse entsoeng ka ho kopanya alumina le zirconia ka likarolo tse fapaneng.Motsoako ona o hlahisa abrasive e matla, e tšoarellang e sebetsang hantle lits'ebetsong tse thata tsa ho sila, joalo ka ts'ebetsong ea ho seha.E boetse e sebetsa ho mefuta eohle ea tšepe le tšepe ea alloy.
Joalo ka alumina, mefuta e mengata e fapaneng ea zirconia alumina e fumaneha.
Silicon carbide ke abrasive e 'ngoe e sebelisetsoang ho sila tšepe e putsoa, tšepe e batang, koporo, boronse e bonolo le aluminium, hammoho le lejoe, rabara le litšepe tse ling tse se nang ferrous.
Alumina ea ceramicke nts'etsopele ea morao-rao ea bohlokoa ts'ebetsong ea abrasive.Ke lijo-thollo tse phahameng tsa bohloeki tse hlahisoang ke ts'ebetso ea gel sintering.Abrasive ena e ka pshatla sekala sa micron ka lebelo le laoloang.Ka lehlakoreng le leng, lintlha tse ncha tse likete lia thehoa.Ceramic alumina abrasives li thata haholo 'me li sebelisoa ha ho siloa ka mokhoa o nepahetseng oa tšepe.Hangata li kopantsoe le li-abrasives tse ling ka tekanyo e fapaneng ho ntlafatsa ts'ebetso ea tsona ka thepa le lits'ebetso tse fapaneng.
