NOZZLE D28 DOUBLE

About NOZZLE D28 DOUBLE

The laser cutting nozzle is a precision-engineered component designed for use in CO and fiber laser cutting machines. Made from high-quality copper, brass, or stainless steel, the nozzle directs assist gas (such as oxygen, nitrogen, or air) into the cutting zone, ensuring optimal cutting performance and edge quality.

Laser nozzles come in various diameters and configurations, such as single or double-layer designs, depending on material type and cutting requirements. They play a critical role in controlling gas flow, cooling the cutting area, and removing molten material, thereby enhancing speed, accuracy, and cut quality.

Q1: What is the purpose of a laser cutting nozzle?
A: The nozzle focuses assist gas into the cutting zone to blow away molten material, prevent oxidation, and improve edge quality and cutting efficiency.

Q2: What's the difference between a single and double nozzle?
A: Single nozzles are typically used for high-speed cutting with oxygen. Double nozzles provide better gas flow control and are used with nitrogen or air for high-quality, oxidation-free cuts.

Q3: How do I choose the right nozzle diameter?
A: Smaller diameters (e.g., 0.8mm) are suitable for thin materials and high-precision cuts. Larger diameters (e.g., 1.5mm) are better for thicker materials and higher cutting speeds.

Q4: How often should I replace a laser nozzle?
A: Replace it if you notice signs of wear such as uneven cutting, poor gas flow, or visible damage. Frequent users may replace nozzles every few weeks.
