Water Jet Cutting

Water Jet cutting is a method of cutting metal with no heat. As the name suggests highly pressurized water is used to slice metal into the desired shape. Water jet cutting provides extreme accuracy and burr-free parts. The automotive, racing and architectural industries employ water jet cutting techniques to create attractive and precise metal parts.

Water Jet Cutting Advantages

Waterjet cutting offers many advantages over more traditional cutting techniques. The primary advantage of waterjet cutting is that the process does not product high levels of heat that can damage the structural properties of the material being cut. In traditional cutting of metals, there is a “heat affected zone” radiating outward from the cutting point in which the grain and structure of the metal is compromised, often reducing its strength or wear resistance.

Another advantage of water jet cutting is the extremely fine and precise cuts that can be made. Non-abrasive waterjet cutting can produce a cut that is only 0.003″ in width — about the width of a human hair. When coupled with computer cutting software to operate the waterjet cutter extremely detailed and precise cuts can be made with an absolute minimum of waste.

Materials That Can Be Cut with Water Jet Cutting

Water jet cutting can be used in a host of industrial applications for cutting just about any kind of material. Water jet cutting was originally developed as a way to cut lumber in the 1950s. In the ’70s the technology advanced enormously when abrasives were added to the pressurized water stream, allowing waterject cutting of much harder materials.

Today water jet cutting is commonly used to cut all kinds of metal and even stone, including granite.

Since water jet cutting uses only water suffused with abrasives (suspended grit) it is considered an incredibly green technology that doesn’t produce environmentally hazardous waste products. Additionally, the precise cutting that is available with water jet cutting technology allows manufacturers to produce less waste product.
