Do you know the accuracy that can be achieved by waterjet cutting

For waterjet cutting, its main advantage is in cutting thickness and accuracy. Now take the CNC cutting machine as an example to make a simple analysis of these two aspects, as follows。

The accuracy of the CNC waterjet cutting machine is strictly speaking. Although the CNC waterjet can cut more accurately than flame and plasma cutting machine tools, it is not a precision machining machine tool and should not be marked with accuracy.

When cutting a sheet of less than 10mm, the cutting speed and compensation are controlled to the right degree, and the error can be +-0.1mm.

The maximum cutting thickness of the CNC waterjet is not easy to clearly define, because the target distance of the water jet is uncertain or variable. The maximum can be 400 or 500mm, and conservatives call it within 100mm, which is reasonable. The current numerical control waterjet generally has a flow rate of 2 to 3 liters and a working pressure of 200 to 380 MPa. The jet passes through the air resistance, and the energy decays extremely fast. When it reaches 400 or 500 mm, it basically drifts away with the wind and has no impact.

For general applications, it is recommended that the thickness of the cut sheet metal should not exceed 100mm, and the thickness of foamed materials such as sponge should not exceed 300mm.

Application range
Waterjet has a wide range of applications, from metallic materials to non-metallic materials, from natural materials to artificial materials, from food to daily necessities, basically capable of cutting, and has the reputation of "universal cutting machine". The main application areas are:
1, ceramics, stone and other building materials processing
2. Glass product processing, such as cutting of glass parts in home appliances, architectural decoration, craft glass
3. Sheet metal cutting in the machinery industry
4. Signs and artistic pattern cutting in the advertising industry
