WATER JET CUTTING PROCESS

HOW DOES WATERJET CUTTING WORK?

A waterjet cutting machine, also known as a water jet cutter or water jet, is an industrial cutting tool capable of cutting a wide variety of materials practically in any form. It is a non-thermal cutting method that is based on a high velocity of a waterjet.

Water is pressured into extremely high pressure (up to 6200 bar) and this jet is focused on the material that needs to be cut. With the power of erosion, the jet will go through the material separating the pieces.

There are two main types of waterjet cutting: pure water cutting with only water and abrasive waterjet cutting where abrasive is mixed to the waterjet. Pure water cutting is used for softer materials such plywood, plastic, or rubber as there the waterjet has enough energy to pierce and cut the material. Adding abrasive and thus creating a mixture of abrasive and water is increasing the energy of the jet and this can be used to cut hard materials such as metals, stone, glass, or carbon fiber. Both methods can be referred as waterjet cutting.

BENEFITS OF WATERJET CUTTING

WHAT ARE THE BENEFITS USING WATERJET?

Improve your competitiveness with the following factors:

  • Versatility: Virtually no material limitations, very thin and very thick materials can be cut by waterjet cutting

  • Quality: no material changes due to heat affect zone, no material distortion, process enabling strict tolerances

  • Efficiency: Minor loss of material due to effective nesting and thin cutting kerf. Wide unmanned cutting options

  • Speed: No additional finishing usually needed, cutting can be done with several cutting heads and stacked materials

  • Complexity: Practically all cutting shapes are possible with 5-axis cutting or robot cutting

  • Environment: No hazardous waste, no toxic fumes

  • Simplicity: All you need is electricity & water, and abrasive for hard materials

CUTTING MATERIALS

WHAT MATERIALS WATERJET CAN CUT?

The undoubted advantage of waterjet cutting is versatility. This cutting method is environmentally friendly and suitable for cutting of nearly all materials, such as aluminum, steel, stone, plywood, rubber, plastic, foam and food. Therefore, waterjet cutting allows fast, cost-effective and ecological cutting in all sectors.

Abrasive waterjet cutting is an often used method for cutting all kind of metals from aluminum foil to steels more than 300mm thick.  One of the biggest advantage of waterjet cutting is the non-thermal cutting method, meaning that the material will not be affected by the heat leaving the surface without burn marks or deformation. Abrasive waterjet easily cut also the toughest materials like titanium or hardox.

Metals

Most common materials:

Steels | Stainless steel | Special steel | Hardox | Titanium | Aluminum | Brass | Copper | Bronze | Iron |

Test cut glass

Abrasive waterjet cutting especially suitable for cutting glass efficiently and precisely. With waterjet technology you can cut holes, edges and even more complex shapes without cracking or damaging the material. The result is a perfectly finished part with sharp edges and less wasted material.

Glass

Most common materials:

Laminated glass | Stained glass | Mirrors | Inlays | Decorations | Window

Wood and especially plywood are suitable for waterjet cutting. Thin plywood can also be cut without abrasives, leaving the natural surface without burn marks. No chemicals, vapor or smoke produced during the cutting process, dust and other particles can be easily and safely filtered from the water.

Wood/Paper

Most common materials:

Cardboard | Plywood | Fabricated wood | Veneer | Packaging materials

Abrasive waterjet technology is an optimal cutting method for cutting stone and tiles. We provide the best technology on the market which allows stress-free cutting eliminating material warping and distortion. You can easily cut complex shapes at high speed without cracking or damaging the material.

Stone/Tile

Most common materials:

Stone | Tile | Ceramics | Granite | Concrete | Marble | Limestone | Porcelain | Kitchen levels

Test cut plastic and rubber

When cutting plastic or rubber with waterjet, no harmful combustion gases are ever released from the material into the environment. Therefore, waterjet cutting is popular in the plastics and rubber industry, allowing for all possible shapes you can think of without changing the cutting tool set. Some materials can also be cut with water-only waterjet.

Plastic/Rubber

Most common materials:

Plastics | Acryl | Foam | Linoleum | Plexiglas | Polycarbonate | Rubber | Soft materials

Test cut metals

When cutting composite materials, it is necessary to consider the different properties of the different layers of the materials. With the right parameters, waterjet cutting is an effective way to cut both shapes and holes.


Most common materials: 

Carbon fiber |Feroform | Kevlar | Glass fiber reinforced materials

WATERJET INSTALLATION

COMPONENTS OF WATERJET CUTTER SYSTEM

Typical waterjet installation includes three basic components: the cutting table, control system and high pressure pump. In addition, you may need an electrical cabinet, abrasive removal system and abrasive feeding system for abrasive waterjet cutting. The required foot print is depending on the size of the cutting table and the selected optional equipment. The smallest table needs only 3 x 3 area. As a family owned company with more than 30 years of experience in waterjet technology we build our machines with high precision and with the principles of longevity, reliability and ease of use.
