  • the slot openings each have a radially extending component. This means that the slot openings do not run only as a circle segment about the axis of the machining direction, but the distances between the two end positions of a front end of a liquid supply line to the axis differ from each other.
  • the deflection of the jet nozzle which can be performed by means of the slot profile, is realized for at least one of the jet nozzles by means of such a design of its liquid feed line, in which the front end of the liquid feed line is displaceable by means of a nozzle manipulator between the rest position of the jet nozzle and its end position.
  • the term slidably includes suitable configurations of the liquid supply lines of the jet nozzles, in which at least the front end and with this the thereto fixed jet nozzle by means of the nozzle manipulator in the range of movement, which allow the slot openings, is movable.

  • a camshaft arranged between the fluid supply lines shifts one or more fluid supply lines outwardly away from the shaft by means of the cams during rotation.
  • the design of the camshaft defines the two end positions per se and the possible displacements of the individual fluid supply lines between their first and second end positions.
  • the position to be set for machining a surface can thus either vary continuously or be fixed by stopping the camshaft a certain position.
  • an eccentric arranged on a shaft can cause the displacement of one or more fluid supply lines, but the variability of the movement is smaller.
  • a high variability and precision of the displacement of the front end can be achieved with a servomotor or several of them, as with this targeted individual positions can be approached.

  • the state of the press pad changes between unfilled and filled.
  • the press pad may also be arranged on the outside and surround the liquid supply lines. In this case, however, the motion sequence of the jet nozzles just described is effected by the transition from the filled to the unfilled pad. In certain applications, the movement can also take place in the opposite direction, from outside to inside, which is also feasible by both types of press pad.
  • a combination of two press pads is, for example, to ensure a more precise positioning and fixing of the jet nozzles.
  • a relative movement of the liquid supply to the press pad may be permitted by: the press pad is compliant in the region of contact with the liquid supply lines or has a lubricious surface.
