87K DWJ Mixing Chamber Assembly

Precision machined stainless housing with a carbide venturi that draws abrasive evenly and keeps the jet coherent at the full 87,000 psi used on Dynamic Waterjet (DWJ) heads. Hardened inlet edges resist chipping, and mirror smooth bores preserve vacuum so garnet feed stays rock steady. Swap this chamber whenever you notice inlet wear or vacuum loss to bring kerf taper and edge quality back to factory spec.

• Knurled Nozzle Nut 60k/90k (711589-1) — secures the chamber/orifice/tube stack inside the DWJ nozzle body.
• Mixing Tube QBIC Plus (010460-xx) — ROCTEC 500 liner that focuses the abrasive jet after the chamber.
• Precision Collet .281 – .242 in (A-23161-8) — locks the mixing tube with repeatable preload.
  

Service tip: replace the mixing chamber whenever inlet edge wear exceeds 0.003". Always install it with a new orifice, mixing tube, collet, and nozzle nut to restore full jet power and protect the new chamber from premature wash out.
