English Translation of Title:
Standard Sapphire Orifice 0.002–0.051 mm – Waterjet Cutting Equipment Accessory (ID: A2260002)

Description, Purpose, Features, and Maintenance:

This component is a precision sapphire orifice with an adjustable or selectable flow diameter ranging from 0.002 mm to 0.051 mm. It is installed at the waterjet cutting head upstream of the abrasive mixing chamber, where it transforms ultra‑high‑pressure water into a coherent, high‑velocity jet that entrains abrasive particles for cutting.

Purpose:

Meters and accelerates water flow at pressures up to 6,000 bar to generate a stable, focused cutting stream.
Controls the water volume and jet diameter to match specific material thicknesses and cutting speed requirements.
Acts as the critical flow‑restricting element that determines jet coherence and abrasive mixing efficiency.

Features:

Fabricated from synthetic sapphire (single‑crystal aluminium oxide), offering exceptional hardness and wear resistance.
Precision‑machined bore ensures consistent flow characteristics and minimal jet divergence.
Chemically inert and fully corrosion‑resistant in high‑pressure water and abrasive slurry environments.
Maintains dimensional stability under extreme pressure and temperature fluctuations.
Compact design allows quick, tool‑free replacement in most cutting head configurations.

Maintenance:

Replace when cutting quality declines, such as increased taper, slower feed rates, or rougher edge finish.
Inspect under magnification for erosion, cracking, or bore enlargement after every 80–120 operating hours.
Handle exclusively with soft plastic or ceramic tweezers; never touch the orifice surface with bare fingers.
Clean using an ultrasonic bath with distilled or deionised water only; avoid solvents that may leave residues.
Install with the correct flow direction as indicated on the component to ensure proper jet formation.
Store spare units in a cushioned, sealed container to protect against impact damage and airborne dust.
