A machining device for machining a workpiece with at least one fluid jet includes 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. The catch basin () is arranged in a free-standing manner in relation to the workpiece support () in order to avoid the transmission of vibrations from the catch basin to the workpiece support.

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

A machining arrangement for drilling a hole into a front wall section of a workpiece by way of a machining jet, the front wall section being located in front of a rear wall section of the workpiece, as seen looking in a drilling direction, the rear wall section being disposed with an intermediate space at a distance from the front wall section, the machining arrangement being switchable between a continuous mode, in which the machining jet formed from liquid and abrasive material continuously impinges on the workpiece, and a pulsed mode, in which the machining jet is pulsed, so that the impingement of at least on of said liquid and said abrasive material on the workpiece is recurrently interrupted, the machining arrangement including a controller which is programmed and configured so that the hole is drilled at least partially in the pulsed mode.

Machining arrangement for drilling at least one hole into a workpiece

The method is used to drill at least one hole into a front wall section of a workpiece () by way of a machining jet formed from liquid, to which abrasive material is admixed as needed. As seen looking in the drilling direction, the front wall section is located in front of a rear wall section of the workpiece, which is disposed with an intermediate space at a distance from the front wall section. The hole is drilled at least partially by the machining jet impinging on the front wall section in a pulsed manner. This pulsed jet is generated by the recurrent interruption of the impingement of the liquid and/or of the abrasive material on the front wall section.

Method for drilling at least one hole into a workpiece

An impact baffle for a jet cutting tool and a method to operate the baffle in conjunction with the jet cutting tool are described, the baffle with an impact layer and an laterally extended sensing layer to trigger a control signal for interrupting a cutting operation of the jet cutting tool after the impact layer is pierced by the jet cutting tool.

A mobile collecting device () for the high-pressure water jet () of a water-jet tool (), especially for working in confined places with difficult access in turbines or the like, in which a more flexible and safer operation is achieved by a closed collecting chamber (), which extends over a large area and includes an outlet (), and in which a rigid first collecting bed () formed of a first high-pressure-resistant material is arranged.

The method for machining a series of workpieces () via at least one machining jet includes the following steps:

Method for machining a series of workpieces by means of at least one machining jet

In the method for cutting a material layer () along a given cutting line (), a cutting beam is moved so as to impinge on the material layer () laterally offset by a distance (W) from the cutting line (). The distance (W) is determined as a function of the variations of the cutting speed at which the cutting beam is moved, and/or as a function of the deviations of the effective cutting beam cross-section from a circular shape.
