Abrasive Water Jet Machining Diagram

At 300 mpa the water jet can exit the nozzle at mach 2 680 m s and at 400 mpa it can have an exit velocity of over mac 3 1 021 m s.

Abrasive water jet machining diagram.

Fig 1 diagram showing the difference between a pure water and abrasive cutting setup a typical waterjet cutter will operate between 300 mpa 40 000 psi 400 mpa 60 000 psi. In order to cut harder materials like metals or granite an abrasive material is mixed in the water. In this process a high speed well concentrated water jet is used to cut the metal it uses the kinetic energy of water particle to erode metal at the contact surface the jet speed is almost 600 m s. In order for the abrasive waterjet nozzle to cut efficiently and to increase component life it is critical that the jewel orifice is carefully aligned in the nozzle body.

30 8 3 waterjet and abrasive waterjet machining. Extremely powerful abrasive waterjets are capable of cutting through 3 inch 76 mm tool steel at a rate of 2 inches per minute 850 μm s 1 10 inch. Abrasive jet machining is a non traditional machining process which is mostly used in machining of hardened metals. It consists of a mixing chamber gas filter pressure gauge regulator and the nozzle.

The figure shown is the above abrasive jet machining. Purposes of jigs and fixtures and their design principles. It uses water jet working as a tool to cut the metal. Manufacturers are increasingly turning to waterjet and abrasive waterjet machining in their quest for productivity and quality.

Note that for a water only nozzle that is designed for cutting soft materials the mixing chamber and tube are eliminated and the coherent jet of water alone cuts the material. Introduction and abrasive jet machining. Abrasive water jet machining developed in 1974 to clean metal prior to surface treatment of the metal. Ultrasonic machining usm water jet and abrasive water jet machining.

In smithells metals reference book eighth edition 2004. It is one of the most famous non traditional machining process because it is environment friendly. The filtered gas at a pressure of 2 to 8 kgf cm 2 is supplied to the mixing chamber containing the abrasive powder and. Abrasive water jet machining awjm is non traditional or non conventional machining process.

In these processes the mechanical energy of water and abrasive phases are used to achieve material removal or machining. Today we will learn about water jet machining and abrasive water jet machining principle working equipment s application advantages and disadvantages with its diagram. Today we will learn about abrasive jet machining principle working equipment s application advantages and disadvantages with its diagram. Design and application of typical jigs and fixtures.
