Product ID: 20477950012 – IDE II Diamond Abrasive Nozzle Assembly (0.012 inch Orifice)

Description:
This component is the IDE II diamond abrasive nozzle assembly, a complete cutting head for ultra-high pressure waterjet systems . It features a premium quality diamond orifice with a diameter of 0.012 inches (approximately 0.30–0.31 mm) that is machine-set for precise alignment within the cutting head . This assembly is rated for 60,000 PSI operation and incorporates the innovative IDE (Integrated Diamond Orifice) design, where the diamond orifice and mixing chamber are combined in a single nozzle body .

The assembly includes a .750 inch left-hand (LH) threaded connection and is designed to be used with a short-stop or thimble-style cutting head filter for warranty compliance and optimal component protection .

Applications:

• Used as the primary cutting head assembly on abrasive waterjet cutting machines for precision cutting of metal, stone, glass, ceramics, composites, and armor plate.

• Installed at the end of the high-pressure water line and abrasive feed system to generate the abrasive cutting jet.

• Suitable for 60,000 PSI (approximately 4,137 bar) ultra-high pressure waterjet systems.

Features:

• Diamond Orifice: The assembly contains a premium-quality diamond orifice that significantly outperforms standard sapphire orifices . Diamond's extreme hardness and wear resistance provide a service life up to 10–20 times longer than sapphire, reducing downtime and maintenance frequency .

• Machine-Set Precision Alignment: The diamond orifice is precisely aligned within the IDE II cutting head at the factory, ensuring perfect coaxial alignment between the orifice, mixing chamber, and focusing tube for optimal cutting performance .

• IDE Integrated Design: The diamond orifice and mixing chamber are combined in a single nozzle body, reducing the number of individual components and simplifying maintenance . The only wear parts requiring regular replacement are the focusing tube and pre-filter .

• 60,000 PSI Rating: Engineered for continuous operation at ultra-high pressure, this cutting head is compatible with standard high-pressure waterjet systems .

• .750 LH Thread Connection: Features a 0.750 inch left-hand threaded connection for secure attachment to compatible high-pressure lines and adapters .

• Short-Stop Filter Compatibility: Requires use with a short-stop or thimble-style cutting head filter to protect the diamond orifice from contamination and maintain warranty coverage .

• Durable Construction: Manufactured from all-metal, high-strength materials to withstand extreme pressure and abrasive environments .

Maintenance:

• Mandatory Filter Use: The warranty for this diamond cutting head is void if used without a short-stop or thimble-style cutting head filter . Always ensure the filter is installed and properly maintained.

• Focusing Tube Replacement: The focusing tube (mixing tube) is the primary wear component. Replace it when cut quality degrades, as evidenced by increased taper, rougher edge finish, or slower cutting speeds .

• Pre-Filter Maintenance: The newly developed pre-filter installed between the high-pressure line and the nozzle valve body should be inspected and replaced regularly. It removes particles that could cause abrasion to the diamond orifice, significantly prolonging nozzle life .

• Orifice Cleaning: Despite water treatment efforts, dissolved solids can collect on the orifice's internal diameter. Periodic cleaning using white vinegar in an ultrasonic cleaner will maintain a clean, coherent waterjet stream and extend orifice life . For long-life orifices such as diamond, rotate to a second orifice while the first is being cleaned, and catalog operating hours to ensure maximum life .

• Leak Inspections: Regularly inspect the cutting head and all high-pressure connections for leaks . Repair any leaks immediately to prevent additional component damage.

• Nozzle Rotation: Even with the precision alignment of the IDE II design, rotate the focusing tube 1/4 turn at the beginning of each shift (or before long projects) to counteract uneven wear and extend component life .

• Clean Area for Maintenance: Perform rebuilds and maintenance in a designated clean area to prevent contamination of replacement parts with abrasive particles . Wear disposable gloves to prevent natural oils from being introduced to seal materials .

• Component Inspection: Regularly inspect seals, O-rings, the focusing tube, and the mixing chamber for signs of wear, damage, or erosion. Replace worn components promptly .

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before performing any maintenance on the cutting head assembly .
