What Is Waterjet Cutting?

Water cutting, also known as water jet, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water cutting. Under the control of the computer, the workpiece can be arbitrarily carved, and it is less affected by the texture of the material. Because of its low cost, easy operation, and high yield, water cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

Water cutting

1. Divided by adding sand:

1. NC forming various complex patterns;

2. It is cold cutting and does not produce thermal deformation or thermal effect;

3. Environmental protection, no pollution, no toxic gas and dust;

4. Can process all kinds of high hardness materials, such as: glass, ceramics, stainless steel, etc., or relatively soft materials, such as: leather, rubber, paper diapers, etc .;

5. It is the only means for complex processing of some composite materials and fragile porcelain materials;

6. Smooth cut, no slag, no secondary processing required;

7. Can complete drilling, cutting and forming work at one time;

8. Low production cost;

9. High degree of automation;

10.24 hours of continuous work ^[1]

1.Wide range of cutting

Can cut most materials, such as: metal, marble,

Due to the energy gradient, the cutting ability of laser, gas plasma, jet and other cutting methods is worse at the deeper cutting plane (the farther away from the nozzle), so the cutting surface formed is often not perpendicular to the surface of the workpiece, which is called cutting Slope, an inherent defect of all cutting methods. Although the cutting slope can be partially reduced by increasing the cutting energy or reducing the cutting speed, there is still a problem that the cutting cannot be performed completely vertically. Therefore, the idea of a tiltable cutting head was put forward in 1997, and there are already commercial products in the world. This is the most direct and effective method to solve the cutting slope and improve the accuracy. The principle is that by adding two additional rotation axes to the original three-axis platform, the cutter head can swing in any direction, and the slope model set in the system is used to calculate the cutting trajectory in real time, and then according to the cut The material and thickness of the workpiece are corrected, and the cutting head is constantly swung during the cutting process, so that the cut workpiece reaches a perfect slope-free state.

Water-cut cutting materials

Ultra-high pressure waterjet can cut all kinds of thick and hard materials: such as stainless steel, aluminum, copper, steel, marble, alloy metal, glass, plastic, ceramics, tiles and various visible materials.

Water cutting cutting accuracy

The precision of cutting the workpiece is between 0.1mm ~ 0.25mm. The accuracy of the workpiece depends on the accuracy of the machine, the size and thickness of the cutting workpiece.

Water cutting gap width

It depends on the size of the cutting material and the nozzle used. Generally speaking, the cut made by sanding is about 1.0mm to 1.2mm. As the diameter of the trowel pipe expands, the cutout becomes larger.

Water cut cutting beveled edge

The cutting speed that is running determines the quality of its hypotenuse. Most of the beveled edges with good cutting quality are about 0.1mm.

Application range of water cutting

Generally speaking, materials with complex patterns, thick, difficult to cut, fragile and hot are most suitable for cutting with waterjet as processing equipment ^[1] .
