Product Features

Features of High-Pressure Air-Assist Nozzle

    • Compatible With All Types of XF+ Laser Heads - A dedicated sleeve is shipped to customers who own the new revised laser engraving and laser cutting XF+ laser head to make it compatible with the nozzle. Four screw holes ensure compatibility with both the previous generation of µSpot Laser Heads and the XF+ Laser Head with the µSpot Lens Upgrade.
    • High-Pressure Airflow - Narrow 2.2 mm aperture at the outlet condenses the airflow for maximum airflow rate.

Features of High-Pressure Air-Assist Nozzle

Focused airflow clears the groove from fumes and pushes hot air forward making the cutting process faster and with a better end-result quality.What we strive to avoid is having a turbulent airflow which makes laser processing slower and the workpiece having charred areas.

  • Convenient Air Hose Connector – It allows to quickly set-up and disassemble the nozzle system.
  • Adjustable Nozzle Height – The nozzle height can be adjusted by +8/-4 mm for the XF+ and +5/-4 mm with the µSpot Lens Upgrade. Enables to utilize the nozzle for laser cutting and laser engraving materials with varied thicknesses, up to 10 mm for the XF+, and up to 7 mm for the XF+ with the µSpot Lens Upgrade. The height of choice is indicated by engraved lines, which make it easier to remember the perfect height for different materials.
  • Airtight O-Ring Seals – Well-adjusted O-Rings ensure maintaining the maximum cleanliness of the front lens as well as steady and precise adjustments to the nozzle height.
  • Light-Weight Aluminium Build – Thin industrial-grade aluminium build yields a negligible added weight, yet forms a sturdy enclosure.
  • Distinctively Designed Outlet Contour – The shape of the air outlet mimics the size of the converging laser beam throughout its length.
  • Smooth Interior Design – Smooth internal surfaces assure quiet operation without any whistling sounds.

Perks of Utilizing the High-Pressure Nozzle

Rapid Laser Cutting with High-Pressure Air-Assist Nozzle

Rapid Laser Cutting and Engraving

The high-pressure air nozzle can speed up laser cutting and engraving by up to 6.5 times once the proper amount of airflow for a particular material is determined. This is achieved by the means of removing smoke, excess soot and carbonized residue particles, which would otherwise obstruct the laser beam.

Reduced Scorching

The addition of the high-pressure air nozzle to your system eliminates or minimizes the occurrence of charred edges. It also allows achieving a more homogenous shade of engravement and better sharpness in the image being engraved.

Reduced Material Scorching with High-Pressure Air Nozzle

Laser Cutting with Uniform Edges

Uniform Edges and Engravement Shades

By removing carbonized residue particles, the high-pressure air nozzle also yields more uniform edges in the object being cut and substantially lessens the risk of the development of edge defects. It also provides a consistent shade in the case of engraving.

Lens Protection

The High-Pressure Air Nozzle protects the front lens from smoke, dust and airborne carbonized molecules, improving its longevity. In addition, it considerably extends intervals between subsequent lens cleaning routines.

Safeguarding the Optics when Operating an Cutting and Engraving Laser

Improved User Safety for Cutting and Engraving with Lasers

Improved User Safety

The nozzle decreases the vacant space between the laser head and the material being processed making it harder for unintended objects to enter the path of the beam.

Enhanced Energy Transfer

The distinct shape of the nozzle allows the airflow to transfer heat directly into and throughout the cut, which improves the heat transfer into the material and provides higher quality laser cutting.

Enhanced Energy Transfer for Laser Cutting and Engraving

Flattening Delicate Materials for Uniform Laser Cutting and Engraving

Delicate Materials Smoothing

High-Pressure Air-Assist Nozzle is particularly useful for cutting and engraving textiles or delicate layers of materials. The pressure from the airflow pushes the material being processed against the surface and flattens any curves, swirls and bumps. Processing a leveled sheet of fabric avoids issues with irregular or deformed cutting lines.

Calibration Versatility

The tip of the nozzle can also serve as an alternative reference point for calibrating the working distance with touch probes (capacitive and non-capacitive touch probes). Using it as a reference point bypasses the need to touch other parts of the laser system such as, for example, the lens in the case of the XF+ Laser Head with the µSpot Lens Upgrade.

Additional Information and Recommendations

Suitable Compressor

Any compressor will be suitable for supplying air to your High-Pressure Air Assist Nozzle unit. However, because the appropriate flow rate must be determined experimentally (for each different type of material to be processed), the desired results may not be achieved with small compressor units. The higher the tank capacity and the compressor performance, the higher the airflow that can pass through the air nozzle. The work is also more comfortable with better compressor units (so that the compressor will not turn on too often in order to refill the tank).We recommend a compressor with a real airflow of 10-12 l/min and a tank capacity of at least 50 liters. However, nothing prevents you from trying a smaller compressor.In fact, many of our customers use small 5 liter tank capacity compressors that are available on Amazon for approximately $50.

Recommended Airflow Values

In our experience, the real airflow value of 10-15 l/min is the upper limit and completely sufficient for most materials. We don't recommend going above 15-20 l/min. Above 20 l/min, the laser cutting speed of all materials decreases. We recommend a real airflow value of 10 l/min as a starting point. Then you could experiment with using a slightly higher airflow rate as the optimum airflow value differs from material to material.

In general, for laser cutting, you will typically find the optimum real airflow value to be between 10-15 l/min.

For laser engraving, we recommend airflow values of 1-3 l/min.

The right base - Honeycomb Table

The Honeycomb CNC table is a great tool that excels in laser cutting and engraving. Its unique design features a honeycomb grid that supports materials during the cutting and engraving process, ensuring precise and accurate results every time. The Honeycomb CNC table is the ideal solution for anyone looking to take their laser cutting and engraving to the next level. You can find the right type and size at Amazon even for ~~ $40-100.
