Used Water Jet Cutting Machines for Sale — 424

Many industries use water jet machines for a range of cutting applications, and there are a variety of automated CNC and advanced 5 axis solutions.

What is a Water Jet Cutting Machine?

A water jet cutter is a high pressure cutting tool that is used in a variety of industries for cutting a range of materials. For soft materials such as plastic, rubber and wood, a water jet cutting machine that uses pure water is often used, while a jet machine using ‘abrasive water’ can cut harder materials including metal and granite.
Water jet cutting machines work by pumping high pressure water or abrasive water through a narrow nozzle directed at a cutting surface, with some tools reaching pressures as high as 100,000 PSI (pounds of force per square inch). The process of cutting materials can be automated using a CNC water jet, and 5 axis water jet cutting machines can produce more intricate 3-D shapes using motion control technology.

What is the structure of a Water Jet Cutting Machine?

High pressure water is fed into the water jet machine through an inlet. Then the water reaches a jewelled opening made of either diamond or ruby. Water passes through this opening and, in the case of abrasive water jet cutting machine tools, an abrasive mixture (made materials such as garnet) is introduced in the mixing tube to aid in the cutting of harder materials. The water then passes out the nozzle at high pressure and onto the cutting surface below.
A portable water jet cutting machine will also have all these components, including a supply of high pressure water, but on a trolley or some other wheeling device. The Water Jet can be connected to a computer device that can relay instructions to the machine, allowing the process to be automated.

What are the different types of Water Jet Cutting Machines?

There are two main types of water cutting machine devices that are ideal for penetrating certain strengths of material. The pure water jet machine uses untreated water to cut soft materials such as wood, and it is the water pressure that does the cutting.
In contrast, the abrasive water jet cutting machine shoots out high pressure water that has been treated with an abrasive. The force of the abrasive hitting the material is what cuts the material, as opposed to the water.
Both types can be bought as a portable water jet cutter and are available in a range of sizes. For automated cutting, there are CNC water jet cutting machine solutions on the market, as well as advanced 5 axis machines for perpendicular and rotation cutting.

Which Industries Use Waterjet Cutting Machines?

Because waterjet cutting machine solutions can cut, ream and shape materials without having to consider the distorting effects of temperature, this tool can be used in many industries, including aerospace and mining. The ability to automate a process with a CNC water jet cutter also makes the water jet an attractive solution in manufacturing, providing accurate and repeatable cuts.
