The destructive force of water is so much that it can cut through the strongest of materials. This principle is utilized by waterjet cutting machines for industrial applications.

Many manufacturers often wonder about the applications of waterjet cutting machines. If you also wonder about what materials can be cut with waterjet cutting machines, this article is the perfect place for you.

In the sections to come, we will discuss the various industries which employ water jet cutting machine applications. You will also learn about the compatible and non-compatible materials for these types of machines.

What are the applications of a waterjet cutting machine?

Water jet cutting machines are straightaway one of the most versatile industrial equipment out there. When we question the applications of these cutting machines, the possibilities are endless. The cutting action of these cutters is achieved through high-speed water created by a high-pressure pump.

While pure waterjet cutters are quite powerful on their own, waterjet cutting commonly utilizes the addition of abrasive materials in the water. These abrasives increase the cutting force of the resultant stream manifold, and the process is called abrasive waterjet cutting.

Here is the list of materials that can be cut by a water jet cutting process, along with the maximum thickness of material that can be cut:

1. Stones & Tiles Cutting

With the addition of abrasives, water jet cutting machines can make precise cuts in granite, marble, porcelain, Dekton, Caesarstone, neolith, ceramics, stone, and tiles.

For cutting ceramic tiles, the maximum thickness supported by waterjet cutters is 2 inches. For marble and granite, waterjet can cut a thickness of up to 6 inches.

2. Glass Cutting

Glass is delicate and can crack easily during the conventional cutting processes. This is why water jet cutting is one of the most commonly used cutting technologies for glass. The 5-axis waterjet cutters allow even intricate cut designs to be placed on a glass workpiece. It is utilized for making cut-outs, frameless showers, holes in splashbacks, and glass architectural applications. For cutting glass with a water jet cutter, there are also a lot of compatible handling devices available at Techniwaterjet that allow for smoother loading and unloading of the product.

For cutting glass, a water jet cutter supports a maximum thickness of 7 inches.

3. Metal Cutting

Water jet cutting can be used to cut any metal like Aluminium, hardened tool steel, titanium, copper, brass, or any other exotic metals. Since water jet cutting does not cause any temperature rise, the structural and chemical integrity of the workpiece remains intact.

The maximum cutting thickness of water jet cutting varies based on the metal. For aluminum, it is 18 inches; for steel 12 inches, and 10 inches for brass and copper.

4. Ceramics

Ceramics are hard-to-machine due to their toughness and often require expensive saw blades. This is why water jet cutting turns out to be a cheaper cutting technique for ceramics.

It can cut ceramics up to a thickness of 8 inches.

5. Plastics

When plastics are subjected to high-temperature tools, it leads to the production of toxic fumes. Therefore, water jet cutting is the safest option for cutting plastics as no temperature rise takes place.

It can cut up to a thickness of 4 inches for the hardest acrylics.

6. Foam and Rubber

Similar to plastic, rubber also releases toxic fumes at high temperatures. Manufacturers around the world use waterjet cutting for processing rubber due to its safety benefits.

This method supports a maximum cutting thickness of 10 inches for rubber and 30 inches for foam.

7. Textiles

Textiles are very flammable and can catch fire easily with any temperature rise. Waterjet cutting is commonly used in textile processing plants as it is a cold cutting method.

It can cut textiles up to 2 inches.

8. Composites

Composites, such as fiberglass and carbon fiber, are common nowadays in a wide array of applications. These composites are soft materials for common cutting methods and can strain or crack when improper force is applied. Waterjet cutting turns out to be one of the best cutting technologies for composites since the force is limited to the point of impact only.

For composites, it can cut a maximum thickness of 6 inches.

9. Food

Food processing industries require a cutting method that involves high cleanliness and no heat changes. Waterjet cutting fits the bill perfectly since it is a cold cutting method with no physical impact of the tool with the cutting surface.

10. Paper and Cardboard

On first impression, it might seem that water jet cutting will be inappropriate for paper as the paper will get wet and ruined. However, the process has been used in the industry for decades now.

For paper cutting, the stream of the water jet is modified and the process is called slitting. It uses a very narrow stream of water that is thinner than even human hair, coupled with high pressure pumps.

11. Insulation Materials

Water jet cutting is also used to make precise cuts on insulation materials such as HVAC liners and PU rubber.

For hard insulation materials, the process can cut a thickness up to 4 inches.

12. Cement Boards

Cement boards are hard to cut with conventional methods. However, with a waterjet cutter, you can make accurate angular cuts on these boards.

For cement boards, the waterjet cutters can support a maximum thickness of 4 inches.

Utilizing one of the most versatile cutting methods it is clear that waterjet machines can cut a variety of materials. Some of the main benefits are highly accurate cutting and low material wastage.
