Advantages of water-jet cutting over other cutting methods (ex Laser Cutting):
- practically no mechanical, heat induced or chemical influence on the workpiece
- no transverse loads are caused. This means that workpieces can be finely processed.
- practically all types of material can be cut
- good quality of cutting surface
- bridges and separating parts of less than 1mm can be manufactured without difficulty
from stiff materials
- even complicated contours can be cut
- low loss of material
- there is no need for holes to be prebored (except in the case of sandwich/stacked/laminated
materials)
A LITTLE WATER JET HISTORY
According to sources from America, the "discovery" of water-jet cutting can be attributed
to a combination of Scottish whisky and the hot Californian sun: The gold digger "Old-Digger-John"
freed gold veins from stone and solid earth with a jet of water. However, it took 100
years before water-jet cutting systems were built for industry.
Repeated efforts to make use of water-jets were made by American and Soviet mining engineers
in 1936. The attempt was made to use the power of the water-jets not only to transport
the coal and rock, but also to mine it. 13 years later, water-jets were being implemented
in America to mine minerals. In 1956, the first attempts were made in what was then the
USSR, in which rock was cut with pressures of up to 2000 bar. The actual water-jet cutting
itself was not patented until 1968 by a professor at the University of British Columbia.
The most commonly used process nowadays is the abrasive water-jet cutting, which is in
fact a process of cutting and grinding: An abrasive material (usually the finest of sands
{e.g. garnet, also used to manufacture sanding paper}) is accelerated by means of a high-pressure
jet of water and then grinds its way through the work piece (quartz sand would be too
soft, i.e. would have too little cutting power). The power potential required for cutting
is obtained by forcing a jet of water no thicker than a hair (approx. 0.1 - 0.8 mm) at
high pressure through a sapphire nozzle (3000 bar and more). Whilst abrasive water-jet
cutting is used to cut metal, glass, stone and ceramics, the pure water-jet is only used
to cut "soft" materials such as foam rubber, cork or carpets; in the case of "hard" materials,
parts would merely be ripped out, since the water itself does not have particularly high
grinding properties.
