Amavili okugaya idayimanezenziwe nge-diamond abrasives njengezinto eziluhlaza kunye nomgubo wesinyithi, umgubo we-resin, i-ceramics kunye ne-electroplated metal njengee-agent ezibophayo.
Ubume beidayimani ivili lokusilayahlulahlulwe ikakhulu yangamacandelo amathathu: umaleko osebenzayo, umaleko we-matrix kunye nowenguquko.
Ngokwesicelo,amavili okugaya idayimanizihlala zisetyenziselwa ukusetyenzwa kwesinyithi kunye nomxholo wentsimbi ephantsi ekunzima ukusetyenzwa ngezixhobo eziqhelekileyo zokuqhawula.Ngokomzekelo, isetyenziswe kwiinkalo ezifana nobunzima obuphezulu, i-alloys enzima kakhulu (i-titanium, i-aluminium), izinto ze-ceramic, njl.
Ngokwesakhiwo,amavili okugaya idayimanizahlukile kumavili abrasive eziqhelekileyo zokusila.Amavili okusila abrasive aqhelekileyo ayenziwa ngokudibanisa ama-abrasives aqhelekileyo kwimilo ethile.Ngokuqhelekileyo zibandakanya izinto ezintathu: i-abrasive, ibhondi kunye ne-pores.Amalungu aphambili aidayimani ivili lokusilangumaleko we-diamond abrasive, inguqu yenguqu kunye ne-matrix.
Uluhlu lwe-abrasive luluhlu olusebenzayo, olukwabizwa ngokuba yi-diamond layer, eyinxalenye esebenzayo yevili lokugaya;
Uluhlu lwenguqu lubizwa ngokuba yi-non-diamond layer kwaye luqulunqwe ikakhulu ngama-binders, i-powders yesinyithi kunye nezigcwalisi.Uluhlu lwenguqu ludibanisa ngokuqinileyo umaleko wedayimane kwi-matrix;
I-matrix isetyenziselwa ukubeka i-abrasive layer.Izinto eziphathekayo ze-matrix zihambelana nempahla ye-binder.
I-Metal bonding agents zisebenzisa intsimbi kunye ne-alloy powder njengesiseko, kunye ne-resin bonding agents zisebenzisa i-aluminium alloy kunye ne-bakelite njengesiseko.
