Ukusetshenziswa okulungile kweukugayauketshezi lubaluleke kakhulu ekugayeni okuphumelelayo. Umsebenzi wokugaya uketshezi ukupholisa nokugcoba indawo ye-arc yokusika. Umsebenzi wokugaya uketshezi olusekelwe emanzini ikakhulukazi ukupholisa kanye nokugcoba. Amafutha okupholisa ikakhulukazi asetshenziselwa ukugcoba futhi anomphumela omncane wokupholisa. Uketshezi lokugaya olusekelwe emanzini olunezithasiselo zokwenziwa ezigcwele lufaneleka kakhulu amasondo okugaya abukhali futhi anamandla. Lolu hlobo lwesondo lokugaya luvamise ukuba ne-arc yokusika ende uma lusebenza, futhi ludinga umphumela ongcono wokukhuhla.
I-semisynthetic additive grinding fluid ifaneleka kakhulu ukugaya izimo eziyinkimbinkimbi futhi ezidinga okuhleukuthambisaukusebenza ukuvimbela ukusha. Amafutha ahlanzekile afaneleka ukugaya izimo eziyinkimbinkimbi, ezifushaneukusikai-arc kanye nezidingo eziphezulu zokuqeda ukugaya. I-ethylene glycol based grinding fluid ilungele izikhathi lapho kusetshenziswa isondo lokugaya i-cubic boron nitride namafutha ahlanzekile kufanele agwenywe.
Ukukhetha uketshezi lokugaya kuwumsebenzi onzima: kokubili intengo yokuqala yokugaya uketshezi kanye nezindleko zokuphatha nokwelashwa kwayo kufanele kucatshangelwe. Lokhu okubizwa ngokuthi "okuluhlaza" okuhambisana nendawo ezungezile kuwukukhohlisa nje. Okunye okupholisayo okusha okunemigqomo kungaphuzwa, kodwa uma imfucumfucu yokugaya isingcolisa uketshezi, izoba udoti oyingozi emvelweni. Uma uketshezi lokugaya lukhethiwe, kufanele luhlungwe futhi lugcinwe. Akudingekile kuphela ukucabangela ukuhlanzeka kwayo, kodwa futhi nokulawula ukugxila kwayo, ukuziphatha kanye nenani le-PH.
Ukuhlolwa kwakamuva koketshezi lokugaya kubonisa ukuthi umthelela wokugxiliswa koketshezi lokugaya enqubweni yokugaya awuqondile. Sekuyisikhathi eside kukholakala ukuthi inqubo yokugaya izothuthukiswa ngokulingana nokwanda kokugxila koketshezi lokugaya, okungalungile eqinisweni. Isibonelo, lapho ukugxila koketshezi lokugaya kungu-7.5% ~ 8%, ukusebenza kwawo akufani nokuka-5%, kodwa lapho ukugxila kunyuswa ku-10% ~ 12%, ukusebenza kwawo kuyathuthukiswa.
Imiphumela yokuhlolwa yezinhlobo ezingu-50 zoketshezi lokugaya olusekelwe emanzini iyafana ngomehluko omncane. Nokho, kwezinye izimo, ukuthambekela akubonakali; Kwezinye izimo, ukugxiliswa kuka-7.5% uketshezi lokugaya cishe kwanele ukubangela ukuthi ithuluzi lomshini limiswe; Uketshezi lokugaya oluno-5% no-10% lusebenza kahle.
