3. NON-TRADITIONAL MACHINING PROCESS
• In this process, a water jet is used ,which act as a tool in the form of a
water saw to cut material.It is two types pure water jet & abrasive
water jet.

WATER JET MACHINING:-
4. PURE WATER JET MACHINING
• PUMP
• INTENSIFIER
• ACCUMULATOR
• HIGH PRESSURE
TUBING
• NOZZLE
• ORIFICE
• CONTROL SYSTEM
• CATCHER
5. ABRASIVE WATER JET MACHINING :-
• Orifice-Sapphires-0.1 to 0.3 mm
• Focussing Tube- 0.8 to 2.4 mm
• Pressure -2500 to 4000 bar
• Abrasive Flow -0.1 to 1.0 kg/min
• Abrasive – garnet and olivine
7. MATERIALS:-
ABRASIVE WATER JET
• Steels
• Non-Ferrous alloyes
• Ti-alloys,Ni-alloys
• Polymers
• Metal Matrix composite
• Ceramic matrix composite
PURE WATER JET
• Concrete
• Stone-Granite
• Wood
• Glass fibre metal
Laminates
8. ADVANTAGES:-
• Cheaper than other process.
• Cut any material
• Water jet cutting does not produce any dust or
particles.
• There is no heat affected zones.
9. DISADVANTAGES :-
• Abrasive powder cannot be reused.
• It is not suitable for mass production because
of high maintenance requirements.
• Very thick parts can not be cut with water jet.
10. APPLICATIONS
WATER JET MACHINING
• Cutting Soft Material
• Textile , Leather Industry
• Mass Immunization
• Surgery
ABRASIVE WATER JET
• Peening
• Cutting
• Pocket Milling
• Drilling
• Turning
• Nuclear Plant Dismantling
11. CONCLUSION:-
There is no conventional tool used, therefore no physical contact
between the workpiece and tool . This method is free from
generate high heat affected zones. It is moreover environmental
friendly, hence it is more preferred.
