English Translation of Title:
Standard Sapphire Orifice 0.004–0.102 mm – Waterjet Cutting Equipment Accessory (ID: A2260004)

Description, Purpose, Features, and Maintenance:

This component is a precision synthetic sapphire orifice with a flow diameter ranging from 0.004 mm to 0.102 mm. It is installed at the waterjet cutting head, upstream of the abrasive mixing tube, where it transforms ultra‑high‑pressure water into a coherent, high‑velocity jet that efficiently entrains abrasive particles for cutting.

Purpose:

• Restricts and accelerates water flow at pressures up to 6,000 bar to generate a stable, focused cutting stream.

• Controls water volume and jet diameter to suit medium‑thickness materials and moderate cutting speed requirements.

• Serves as the key flow‑regulating element that influences jet coherence, abrasive mixing efficiency, and edge quality.

Features:

• Fabricated from synthetic sapphire (single‑crystal aluminium oxide), offering extreme hardness and superior wear resistance.

• Precision‑machined bore delivers consistent flow characteristics and minimal jet turbulence.

• Chemically inert and fully corrosion‑resistant in high‑pressure water and abrasive slurry conditions.

• Maintains dimensional accuracy under continuous pressure cycling and temperature changes.

• Compact, lightweight design allows quick replacement without special tools.

Maintenance:

• Replace when cutting performance declines, evidenced by slower feed rates, wider kerf, or increased surface roughness.

• Inspect under magnification for signs of erosion, cracking, or bore enlargement after every 80–120 operating hours.

• Handle exclusively with non‑metallic tweezers; avoid finger contact to prevent contamination.

• Clean using an ultrasonic bath with deionised water only; do not use abrasives or aggressive solvents.

• Install with the correct flow direction as indicated on the component to ensure optimal jet formation.

• Store spare orifices in a cushioned, dust‑free container to prevent edge chipping or scratching.
