Mashiinka Abrasive Jet Machining (AJM) waa hannaan makiinadeed oo adeegsada qaybo yaryar oo xoqan oo xawli sare laga soo saaro godadka sanbabada 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 daadin pre-daawaynta ama ka dib, in wax soo saarka, dhibcood machining yar yihiin aad ugu habboon goynta saxan, polishing meel bannaan, shiidan, jeestay, qodista iyo tolida dusha sare, taas oo muujinaysa in jet abrasive loo isticmaali karaa sida giraangiraha shiidi, qalab rogid, qalab dhaqameed oo kale.
Oo laga soo bilaabo dabeecadda ama xididka jetka, tignoolajiyada jet-ka abrasive waxay u qaybsantaa (abrasive) jets-biyoodka, jetka qulqulka, jetka hawada naaxinta iyo wixii la mid ah. Maanta, waxaan marka hore ka hadli doonaa horumarinta tignoolajiyada jet biyaha abrasive.
Jet-biyoodka abrasive waxaa lagu horumariyaa 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. Waagii hore, cadaadiska ay jet-biyoodku gaari karto waa 10 MPa, waxaana loo isticmaali karaa oo kaliya in lagu dhaqo dhuxul dhuxusha, jarista agabyada jilicsan sida waraaqaha iyo dharka, iwm. Si kastaba ha ahaatee, iyadoo ay weheliso horumarinta sayniska iyo tignoolajiyada, noocyo kala duwan oo cusub oo xiiso leh ayaa ka soo muuqday garoonka diyaaradaha biyaha caalamiga ah dhammaadkii 1970-yadii, wakiil ka mid ah kaas oo ah Abrasive Mohamed WJ by Dr.
