The nozzle assembly for use in a fluid-jet cutting apparatus comprises a body (10) having an internal mixing region (20), means (14, 23, 15, 17, 27, 21) for defining a first orifice for directing a high velocity fluid jet along a generally axially extending path and through the mixing region, a conduit (18) in fluid communication with the mixing region (20) and adapted to conduit abrasive into the mixing region (20) and further comprising a second conduit means in communication with the mixing region (20) for discharging the abrasive-laden jet along a second generally axially extending fluid path. The invention provides for adjustment means (22) for co-axially aligning and/or correcting the alignment of the direction of the high velocity fluid jet (26) with the second discharging conduit means (16). |
