A fluid jet cutting machine comprising a selectively contactless or tactile sensor system for determining a spacing between the cutting device (outlet of the jet pipe) and the work piece. This device automatically trails the drive of the cutting head to maintain a defined constant spacing. An inductive sensor is used for metallic work pieces. The inductive proximity sensor is concentrically arranged around the jet pipe and determines, in a contactless manner, the spacing from the work piece, and transmits corresponding electrical signals to the drive of the cutting head for controlling the spacing. The inductive sensor is designed so that a ring chamber is concentrically arranged extending along the jet pipe leading to the outlet of the jet. It is possible to provide a pressurized flushing medium through this ring chamber via feed lines. This flushing medium flushes away the material removed by abrasion and the rebound particles in the course of the drilling and cutting process. A tactile attachment system is used with nonmetallic work pieces. The system is secured in a simple manner, on the main body of the sensor system.
