Machining device for machining a workpiece by means of at least one fluid jet

1. A machining device for machining a workpiece by means of at least one fluid jet, comprising

a workpiece support for supporting the workpiece, and

a catch basin for dissipating the energy of the at least one fluid jet after its penetration of the workpiece, wherein

the catch basin is arranged in a self-supporting manner in relation to the workpiece support in order to avoid the transmission of vibrations from the catch basin to the workpiece support, and

wherein the catch basin includes side walls, which extend vertically from a bottom of the catch basin beyond a level at which the workpiece support is located such that the workpiece is located within the catch basin, below an uppermost surface of said side walls, thereby allowing the catch basin to be filled with water up to the workpiece.

2. The device according to claim 1 , further comprising a cutting head, which is displaceably arranged, the at least one fluid jet is discharged from the cutting head in the machining process.

3. The device according to claim 2 , wherein the cutting head is movably arranged in three translational axes.

4. The device according to claim 2 , further comprising a machine support, on which the cutting head is displaceably arranged, wherein the workpiece support is fixedly connected to the machine support.

5. The device according to claim 4 , wherein for its exchange, the workpiece support is detachably connected to the machine support.

6. The device according to claim 4 , further comprising fastening elements, which are fastened to the machine support and on which the workpiece support is resting.

7. The device according claim 6 , wherein the catch basin has passages, through which the fastening elements extend.

8. The device according to claim 7 , further comprising seals for sealing the passages.
