Mashiinka Abrasive Jet Machining (AJM) waa hannaan makiinadeed oo adeegsada qaybo yaryar oo xaaqid ah oo laga soo saaray xawaare sare oo ka soo baxaya godadka biibiile si ay ugu dhaqmaan dusha sare ee qalabka shaqada, shiida iyo ka saarista walxaha iyada oo loo marayo isku dhaca xawaaraha sare leh iyo xiirid qaybaha.
Jet abrasive marka lagu daro daawaynta dusha sare ee dhamaystirka dusha sare, oo ay ku jiraan daahan, alxanka iyo dajinta pre-daaweynta ama daaweynta ka dib, ee wax soo saarka, dhibcood machining yar ayaa aad ugu habboon goynta saxan, polishing dusha bannaan, shiidan, jeestay, qodista iyo tolitaanka dusha sare. , taas oo muujinaysa in jet-ka abrasive loo isticmaali karo sida giraangiraha shiidada, qalabka rogid, gooya wax-shiidka, daloolista iyo qalabyada kale ee dhaqanka.
Oo laga soo bilaabo dabeecadda ama xididka jetka, tignoolajiyada jet-ka abrasive waxay u qaybsantaa (abrasive) jets-biyoodka, jets-ka slurry, jets hawada naaxinta iyo wixii la mid ah.Maanta, waxaan marka hore ka hadli doonaa horumarinta tignoolajiyada jet biyaha abrasive.
Jet-biyoodka abrasive waxaa lagu sameeyay iyadoo lagu salaynayo jet biyo saafi ah.Water Jet (WJ) waxay asal ahaan ka soo jeedaan 1930-meeyadii, hal aragti ayaa ah dhuxusha miinada, mid kalena waa in la gooyo walxo gaar ah.Maalmaha ugu horreeya, cadaadiska ay jet-biyoodku gaadhi karto waa 10 MPa, waxaana loo isticmaali karaa oo kaliya in lagu dhaqo dhuxusha, jarista alaabta jilicsan sida waraaqaha iyo dharka, iwm. Si kastaba ha ahaatee, iyada oo la socota horumarinta sayniska iyo tignoolajiyada. noocyo kala duwan oo cusub oo xiiso leh ayaa ka soo muuqday garoonka diyaaradaha caalamiga ah dhamaadkii 1970-meeyadii, kaas oo wakiil ka ah Abrasive Water Jet (AWJ) oo uu soo jeediyay Dr Mohamed Hashish 1979kii.
