The main benefit of a four-axis cutting head is to compensate taper, and to make the finished edge completely vertical through the fourth axis – a rotational axis. The four-axis cutting head actually has the structure of a five axis, which purposely has one axis under manual control b the angle axis. Together with the original three-axis (X Y Z), we label them as a four-axis cutting head. Since it has the fifth angle axis under manual control, it can also perform cutting with the entire five axis.
This specially engineered cutting head has performed remarkably in many cutting fields in reducing the processing cost due to increased operating efficiency.
Compared with our five-axis cutting head design, it has a maximum limit of a 4 degree angle with a rotational accuracy of 0.01 degrees.
For taper compensation, the distance between the cutting head and the surface of the work piece must be maintained with high accuracy. The height positioning accuracy of the four-axis is 0.01mm and the cutting accuracy is 0.1mm, which can easily meet various cutting requirements.
In the marble matching process, waterjet cutting with a four-axis cutting head design is simply amazing. When the angle of the cutting head reaches 4 degrees, the finished edge shows tremendous improvement. As can be seen from this picture, there is no gap between the two joined surface. Hence, a secondary polishing procedure is no longer required. Thereby, it increases working efficiency and reduces the production cost.
With this improved four-axis dynamic cutting head design, it is no longer a difficult technique in marble matching. It made traditionally complex marble matching an easy job.
The same methodology is also applicable in glass straight-hole drilling. As an example, when piercing holes in glass, it is not necessary to decrease the cutting speed in order to get straight holes. The ideal effect can be achieved without changing cutting speed, and that is highly beneficial!
