Ekucutshungulweni kwengilazi yesimanje, ukufeza ukuqedwa kobuso obufanayo nobucwengekile kubalulekile kokubili ekusetshenzisweni kobuhle kanye nokusebenza kahle. I-alumina emhlophe ehlanganisiwe engu-180 grit ivele njengendlela yokukhuhla ekhethwayo yokuqhuma kwesihlabathi sengilazi ngenxa yekhono layo lokusika elilinganiselayo kanye nokusatshalaliswa kosayizi wezinhlayiya ezincane.
Njengoba inosayizi wezinhlayiya omaphakathi ongaba ama-micron angu-80-90, i-alumina emhlophe ehlanganisiwe engu-180 ihlinzeka ngomphumela oqhubekayo weqhwa ngaphandle kokubangela umonakalo omkhulu womphezulu. Ukuhlanzeka kwayo okuphezulu (≥99% Al₂O₃) kanye nokuqukethwe kwayo okuphansi kwensimbi kuqinisekisa ukuthi akukho mbala noma ukungcola okwenzekayo ngesikhathi senqubo yokuqhumisa, okwenza ifaneleke kakhulu engilazini yezimboni yokwakha, yokuhlobisa, kanye neyezinga eliphezulu.
I-modology yezinhlayiya ze-angular inikeza isenzo sokusika esincane esilawulwayo, okuvumela opharetha ukuthi bafeze ukuqedwa okubushelelezi, okungacwebezeli kahle ngokufana okuhle kakhulu. Uma kuqhathaniswa ne-abrasives eqinile, i-grit engu-180 inikeza ukucwengwa okuphezulu kwendawo, okwenza kube kuhle kakhulu ekusetshenzisweni okufana namaphaneli engilazi, izindawo zokuvala ishawa, izingxenye, kanye nokuqoshwa kwelogo okunembile.
Ngaphezu kwalokho, ubulukhuni bayo obuphezulu (Mohs 9) kanye nokumelana nokuguguleka okunamandla kunegalelo ekwandiseni isikhathi senkonzo kanye nokusetshenziswa kabusha, kunciphisa izindleko zokusebenza zizonke. Uma isetshenziswa ngaphansi kwezimo ezilungiselelwe kahle—ngokuvamile ekucindezelweni okuphakathi kuka-0.4–0.7 MPa kanye nama-engeli okuqhuma afanele—i-alumina emhlophe ehlanganisiwe engu-180 grit iqinisekisa kokubili ukusebenza kahle kanye nekhwalithi.
Njengoba isidingo sokuqedwa kwengilazi yekhwalithi ephezulu siqhubeka nokukhula, i-alumina emhlophe ehlanganisiwe engu-180 grit isalokhu iyisisombululo esithembekile kubakhiqizi abafuna ukunemba, ukuhambisana, kanye nokusebenza okungabizi kakhulu emisebenzini yokuqhumisa isihlabathi.
