	Laser Beam versus Water Jet Machining
		This generally means that the focus head on a CO machine moves only in one (Z) axis to provide height and focus adjustment, the X and Y axes being controlled by movement of the table, thus increasing the effective footprint of the machine.
		Water jet machining is used extensively for cutting plastics, fabric, rubber, paper and leather due in part to the absence of heat.
		Water jet machining is a very clean operation with no dust or odours and very little noise, in fact the health and safety and environmental implications are almost negligible.

	Laser cutting vs. water jet cutting - standard metal cutting processes
		Water jet cutting is a process used to cut materials using a jet of pressurized water as high 60,000 pounds per square inch (psi).
		Often, the water is mixed with an abrasive like garnet that enables more materials to be cut cleanly to close tolerances, squarely and with a good edge finish.
		Water jets are capable of cutting many industrial materials including stainless steel, Inconel, titanium, aluminium, tool steel, ceramics, granite, and armor plate.

	Introduction to waterjet machining
		It is important to understand that Abrasive jets are not the same thing as water jets, although they are nearly the same.
		Water jets use the beam of water exiting the orifice (or jewel) to cut soft stuff like diapers and candy bars, but are not effective for cutting harder materials.
		The high velocity water exiting the jewel creates a vacuum which sucks abrasive from the abrasive line, which mixes with the water in the mixing tube to form a high velocity beam of abrasives.

		Not only are they able to cut with precision and efficient acceleration, water jet cutting robots do not aggravate or increase the typical working environment problems - dust, noise and emissions - that plague most lines.
		Abrasive jets are sometimes prone to wandering during machining, and lags in the cutting, especially at corners, can be problematic - especially when appearance is a high priority in the goods you're manufacturing.
		On the premises we boast our own machine shop and exceptionally maintained parts cleaners, wash booths, sanding booth and paint booth, as well as a staff of robot specialists who share 100-plus years of combined experience in the industry.

	Water Jet Cutting Process (Site not responding. Last check: 2007-10-11)
		Water Jet Cutting is a process of machining utilising water & abrasives that are pressurised to create a 'beam' of fluid that will cut through almost any material.
		The water is pressurised at up to 4000 bar (60,000 psi) and then forced through a directional nozzle.
		Abrasives within the solution ensure that the cut is swift and smooth with minimal edge burring and no material deformation.
