FIELD: grinding; polishing.
SUBSTANCE: invention relates to liquid jet cutting devices, in particular to fluid jet receiving receptacles. Device comprises a nozzle collecting a jet receiver positioned opposite the nozzle for receiving a fluid. Inlet of the jet receiving receptacle is elongated along the direction of movement of the nozzle to receive the fluid in the deflected state. Jet deflector is installed downstream of the elongated inlet for receiving and directing, during processing of the preform, a portion of the fluid jet to collide with the jet reflector installed above the jet reflector.
EFFECT: invention makes it possible to improve the performance characteristics of the device, as well as to eliminate defects in the surface of the workpiece being processed.
