ABSTRACT:
A waterjet head is resiliently supported at one location along its axis and is pivotally supported at another, axially spaced location. The head is driven in a pivoting, oscillating manner by a drive system including a rotary motor and an eccentric. The outlet nozzle of the waterjet head pivots in an orbital path so that the UHP liquid or liquid/abrasive stream discharged from the nozzle describes an orbital path on an adjacent workpiece surface, enabling the stream to carry out a uniform surface treatment operation such as cleaning, polishing or milling without damaging the workpiece surface.
