English Translation of Title:
Standard Sapphire Orifice 0.007–0.178 mm – Waterjet Cutting Equipment Accessory (ID: A2260007)

Description, Purpose, Features, and Maintenance:

This component is a precision synthetic sapphire orifice with a flow diameter ranging from 0.007 mm to 0.178 mm. It is mounted at the waterjet cutting head, upstream of the abrasive mixing tube, where it converts ultra‑high‑pressure water into a coherent, high‑velocity jet that entrains abrasive particles for efficient cutting of medium to heavy‑section materials.

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 thicker materials and higher cutting speed requirements.

• Acts as the primary flow‑regulating element that influences jet coherence, abrasive mixing efficiency, and overall cutting precision.

Features:

• Manufactured 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, increased surface roughness, or greater taper angle.

• 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.
