Waterjet cutting system features endlessly rotating cutting head
Knuth’s Hydro-Jet 2-D waterjet cutting systems now can be equipped with an optional 5-axis cutting head for endless rotation. The compensation of the downwardly tapered cutting kerf by an adapted angular setting allows higher component accuracies for 2-D cutting with increased cutting speeds, according to the company.
The 5-axis cutting head is based on the design principle of the Nutator, wherein the two axes of rotation are at an angle of 45 degrees to each other: On the one hand, a rotation around the Z axis and, on the other hand, a rotation around an axis oriented under 45 degrees to the Z axis, which forms a 45 nutation cone when the cutting head rotates around the Z axis. The tip of this nutation cone is the tool centerpoint, where the stream contacts the workpiece. Therefore, rotational movements of the cutting head lead to no change of position.
A rotary element is incorporated to allow a continuous transport of the abrasive sand under the various conditions of processing and for the different sand properties.
Contours can be created without interruption of the cutting process, which require rotations around the Z axis with a multiple of 360 degrees.
