Ka tapahia ngā ngongo alumina uku ātete-kakahu mā roto i tētahi raupapa o ngā tukanga.
Tuatahi, ko te rauemi mata o ngā paipa alumina uku ātete-kakahu ko te Al2O3 ahumahi, he mea hanga mai i te bauxite (Al2O3▪3H2O) me te diaspore. Mō te Al2O3 he nui ngā whakaritenga parakore, ka hangaia mā ngā tikanga matū. I te wā o te tukanga whakarite, ka tāpirihia te ngongo uku alumina ki ngā rauemi uku whakakotahi pērā i te zirconium oxide, te silicon oxide, te silicon nitride me ētahi atu paura i te wā e whakapūkarahia ana hei whakanui ake i tōna pakeke me tōna kaha.
I te wāhanga tapahi, ko te tapahi i ngā paipa uku alumina e whakawhirinaki ana ki ngā taputapu tukatuka tino tika, pērā i ngā mīhini tapahi waea tere, ngā mīhini tapahi waea puhoi rānei. He pai ngā mīhini tapahi waea tere mō te tukatuka i ngā paipa uku alumina he iti ake te diameter me ngā whakaritenga maeneene mata teitei ake; ko ngā mīhini tapahi waea puhoi ia e pai ana mō te tukatuka i ngā paipa uku alumina he nui ake te diameter me ngā whakaritenga maeneene mata iti ake. I te wā tapahi, me aro nui ki te koki tapahi me te tere tapahi kia pai ai te maeneene me te tika o te mata tapahi.
Hei tāpiritanga, ko te tapahi i ngā paipa uku alumina ka uru pea ki ngā tukanga tukatuka pēnei i te huri me te huri. Ko te tukanga huri he mīhini huri te nuinga. Ko te taputapu huri ka taea te whakamahi i te wira huri, i te wira huri CBN rānei. Me aro ki te kaha o te huri me te wā huri kia pai ai te maeneene me te tika o te mata o te paipa uku alumina. Ko te tukanga huri ka whakamahia ngā mīhini huri, ā, ko ngā taputapu huri ka taea te whakamahi i ngā taputapu huri maitai tungsten, i ngā taputapu huri carbide rānei.
I te nuinga o te wā, he tukanga uaua te tapahi me te hanga i ngā ngongo alumina uku ātete-kakahu e hiahia ana ki ngā taputapu tukatuka tino tika me te whakahaere tukanga pai hei whakarite i te kounga me te mahi o te hua whakamutunga.
