Technology that's Watered down — but Never Weak

To dramatically oversimplify – Take the most abundant liquid on Earth, put it under high pressure, let it escape through a small hole, inject some sand into the stream, and you can cut anything. This is basically the outline of a modern waterjet machine tool. Granted that we are considering pressures that are greater than on the bottom of the deepest ocean and the sand is usually crushed garnet, but the concept is about right.


Waterjet cutting technology has matured from its very early days in the 1950s when it was initially studied for use in cutting lumber. Waterjet cutting technology, and if sand or crushed garnet is used, the process is called abrasive-waterjet, has many applications in the modern machine shop. Waterjet cutting processes are one of the most versatile and fastest growing machining operations in the world and 5-axis waterjet machines are currently available.

Very often waterjet processes can complement other manufacturing technologies as no noxious gases or liquids are used. Waterjets do not create hazardous materials or vapors, and they do not create heat-affected zones or mechanical stresses in the materials cut. In certain situations, waterjets can accomplish cutting tasks in less time than conventional technologies, and sometimes they can do things that other technologies cannot.

IMTS is this year’s preeminent location to see the latest developments from waterjet technology providers. No other place on Earth will bring the latest and greatest innovations and technology developments together in one place.

If you’re thinking about additional capabilities for your machine shop, waterjet operations should be on your list. Waterjet machine developers are continually upgrading and incorporating the latest research from both private-sector companies and universities. Many are expanding on their own capabilities by exploring the dynamics of cutting newer metals, ceramics, and various composites. Also, more recent research has focused on waterjet micro-machining. So this may also be an area worth exploring.

It is ironic that on your lookout for a competitive edge in the manufacturing environment, the answer may be a machine tool that has actually no cutting edge at all ... just a jet of water.
