I-Abrasive Jet Machining (AJM) iyinqubo yokwenza esebenzisa izinhlayiya ezincane ezilumayo ezikhishwa ngesivinini esikhulu ukusuka ezimbotsheni zomlomo womlomo ukuze zisebenze phezu kwendawo yokusebenza, zigaye futhi zikhiphe izinto ngokungqubuzana kwesivinini esikhulu kanye nokugunda kwezinhlayiya.
Indiza e-abrasive ngaphezu kokwelashwa okungaphezulu kokuqedwa kwendawo, okuhlanganisa ukunamathela, ukushisela kanye nokucwenga ngaphambi kokwelashwa noma ngemva kokwelashwa, ekukhiqizeni, amaphuzu amancane omshini afaneleka kakhulu ukusika amapuleti, ukupholisha indawo yesikhala, ukugaya, ukujika, ukubhola kanye nokulukwa kwendawo. , okubonisa ukuthi i-jet abrasive ingasetshenziswa njengesondo lokugaya, ithuluzi lokuguqula, i-milling cutter, i-drill namanye amathuluzi endabuko.
Futhi kusukela kumvelo noma impande ye-jet, ubuchwepheshe be-jet abrasive buhlukaniswe (abrasive) amajethi amanzi, ama-slurry jets, ama-air jets abrasive nokunye.Namuhla, sizokhuluma kuqala mayelana nokuthuthukiswa kobuchwepheshe bejethi yamanzi abrasive.
Ijethi yamanzi abrasive ithuthukiswa ngesisekelo sejethi yamanzi ahlanzekile.I-Water Jet(WJ) yasungulwa ngeminyaka yawo-1930s, enye ithiyori ukumba amalahle, enye ukusika into ethile.Ezinsukwini zakuqala, ingcindezi ijethi yamanzi engafinyelela kuyo ingaphakathi kwe-MPa eyi-10, futhi ingasetshenziswa kuphela ukuthungatha imithungo yamalahle, ukusika izinto ezithambile ezifana nephepha nendwangu, njll. Nokho, kanye nokuthuthukiswa kwesayensi nobuchwepheshe, izinhlobonhlobo zezitayela ezintsha ezithokozisayo zavela emkhakheni wendiza yamanzi yamazwe ngamazwe ekupheleni kweminyaka yawo-1970, emele i-Abrasive Water Jet(AWJ) eyahlongozwa nguDkt Mohamed Hashish ngo-1979.
