Apparatus for generating and manipulating a high-pressure fluid jet

A high-pressure fluid jet system comprising:

• a motion assembly for manipulating a high-pressure fluid jet assembly and having a gimbal wrist configured to be coupled to a bridge for motion along an axis of the bridge, the gimbal wrist being provided with a first motor having a first axis of rotation and with a second motor having a second axis of rotation, the first and second axes of rotation being neither parallel nor perpendicular to the axis of the bridge;
• a cutting head assembly having a body adapted to receive an orifice at an orifice location for generating a high-pressure fluid jet;
• a clamp positioned around the body of the cutting head assembly for coupling the motion assembly to the cutting head assembly;
• and
• a nozzle body assembly removably coupled to the cutting head assembly, the clamp holding the cutting head assembly when the nozzle body assembly is separated from the cutting head assembly, thereby allowing access to the orifice location without removing the cutting head assembly from the clamp.
