Ama-abrasives angahlukaniswa ngezigaba ezimbili: ama-abrasives ajwayelekile (njenge-aluminium oxide, i-silicon carbide, njll.) kanye nama-abrasives aqinile (idayimane, i-cubic boron nitride, njll.).
I-CBN ne-Jinzeshi ziqinile futhi azikwazi ukugqokwa kunama-abrasives avamile, kodwa zibiza kakhulu.Ngesikhathi esifanayo, ama-abrasives aqinile angama-conductor okushisa amahle kakhulu (i-thermal conductivity yedayimane iphindwe izikhathi ezingu-6 kunethusi), kanti ama-abrasives ajwayelekile ayizinto ze-ceramic, ngakho-ke ziyi-adiabatic.
I-Superhard abrasive futhi inokushisa okuphezulu kwe-thermal, okungukuthi, inamandla okukhipha ukushisa ngokushesha.Lesi sici senza i-superhard abrasive ibe nemvelo "yokusika okubandayo".Ukumelana nemihuzuko yama-abrasives aqine kakhulu nakho kungcono kakhulu kunokwama-abrasives ajwayelekile, kodwa lezi zici zama-abrasives aqine kakhulu azisho ukuthi alungele wonke umuntu.izinqubo zokugaya.
I-abrasive ngayinye inenkambu yayo yesicelo efaneleke kakhulu, ngakho-ke kubalulekile ukuqonda izici ze-abrasive ngayinye.Isibonelo, ama-abrasive e-alumina ceramic - ngezinye izikhathi abizwa ngokuthi ama-abrasives ejeli lembewu (SG) noma ama-abrasives e-ceramic - ngokuvamile anokumelana nokuguga okungcono nokugcinwa komumo kune-alumina encibilikisiwe (evamile).Kodwa-ke, ama-abrasives e-ceramic nawo anezinkambu ezifanele kakhulu zokufaka isicelo.
I-Alumina: I-Al2O3 iyi-abrasive eshibhe kakhulu.Lapho ugaya insimbi eqinile, ukusebenza kuhle kakhulu.Ngaphansi kwesimo sokugqoka okuqhubekayo, i-nickel base superalloys nayo ingaba phansi.I-Al2O3 inokuvumelana nezimo ezinhle ezihlukahlukeneukugayaizimo, ezifana nezinto ezithambile neziqinile, ukusika okulula nokusika okunzima, futhi kungagaya isiphetho esiphezulu kakhulu.
I-alumina ye-Ceramic: i-alumina ye-ceramic inamandla amakhulu, ngakho-ke ifaneleka kakhulu izikhathi lapho umthwalo wamandla okusika wezinhlamvu ze-abrasive ngayinye uphezulu.I-alumina ye-Ceramic iphumelela kakhulu ekugayeni okuyi-cylindrical kanye nendiza enkulu ephindaphindayo ukugaya kwensimbi eqinile.Kodwa ayifanele ukusika i-arc ende namandla amancane okulayisha okusanhlamvu okuhuqayo okukodwa, okufana nokugaya okuyisiyingi kwangaphakathi, ukugaya ukudla okukhasa, njll. Nokho, izinhlayiya ze-ceramic alumina abrasive eziguquliwe "ngokwelula" zingasetshenziswa futhi ukucubungula i-viscous.insimbi engagqwali, i-superalloy, njll ngisho nalapho i-arc yokusika iyinde.Ngalesi sikhathi, isilinganiso somumo (isilinganiso sobubanzi bobude) sezinhlayiya ezilumayo sifinyelela ku-5.
