A nozzle for a tool for the working of material and having a nozzle body which is composed of electrically conducting material and carries a nozzle electrode in its tip region with the tip region of the nozzle body and the remaining region of the nozzle body being formed by separate parts which are connected to one another and electrically insulated from one another, the nozzle electrode being in direct electrical contact with the tip region.

Nozzle for a tool for the working of material

A nozzle for a device for machining materials, can be rigidly connected at its end opposite the nozzle tip to a connector head of the device. The connection of the nozzle with the connector head is made by a connecting element (7; 17) made of a brittle material and comprising a break-off region (11; 20). If a collision between the nozzle tip and a workpiece to be machined takes place accidentally, then the connecting element breaks in the break-off region in order to prevent further, even greater damage to the connector head, nozzle or workpiece. The break-off region is crossed by an electrical conductor (14; 27) which breaks in the event of a collision, so that in this way an alarm signal for stopping the device can be generated.
