I-Abrasive Jet Machining (AJM) inqubo yokugaya esebenzisa izinhlayiya ezincane ezihudulayo ezikhishwa ngesivinini esikhulu ezivela emigodini ye-nozzle ukuze zisebenze ebusweni bento yokusebenza, zigaye futhi zisuse izinto ngokushayisana okusheshayo nokugundwa kwezinhlayiya.
Ijethi ebhulazayo ngaphezu kokwelashwa kwendawo yokuqedela indawo, okuhlanganisa ukumboza, ukushisela kanye nokufaka iplati ngaphambi kokwelashwa noma ngemva kokwelashwa, ekukhiqizeni, izindawo ezincane zokugaya zifaneleka kakhulu ekusikeni amapuleti, ukupholisha indawo, ukugaya, ukujika, ukubhoboza kanye nokuluka indawo, okubonisa ukuthi ijethi ebhulazayo ingasetshenziswa njengesondo lokugaya, ithuluzi lokujika, umsiki wokugaya, ukubhoboza kanye namanye amathuluzi endabuko.
Futhi kusukela ohlotsheni noma empandeni yejethi, ubuchwepheshe bejethi ebhulazayo buhlukaniswe ngamajethi amanzi (abhulazayo), amajethi e-slurry, amajethi omoya abhulazayo njalo njalo. Namuhla, sizoqala ngokukhuluma ngentuthuko yobuchwepheshe bejethi yamanzi ebhulazayo.
Ijethi yamanzi e-abrasive yakhiwa ngesisekelo sejethi yamanzi ahlanzekile. I-Water Jet (WJ) yaqala ngawo-1930, enye inkolelo-mbono iwukumba amalahle, enye iwukusika izinto ezithile. Ezinsukwini zokuqala, ingcindezi engafinyelelwa yijethi yamanzi ingaphakathi kwe-10 MPa, futhi ingasetshenziswa kuphela ekuhlanzeni imithungo yamalahle, ukusika izinto ezithambile njengephepha nendwangu, njll. Kodwa-ke, kanye nentuthuko yesayensi nobuchwepheshe, kwavela izitayela ezintsha ezahlukahlukene ezijabulisayo emkhakheni wejethi yamanzi yamazwe ngamazwe ekupheleni kwawo-1970, okumelela i-Abrasive Water Jet (AWJ) eyaphakanyiswa nguDkt. Mohamed Hashish ngo-1979.
