Water-guided laser cutting technology is a processing method that combines high-energy pulse lasers with guided water jets. By coupling laser energy into a water jet, it achieves cutting and processing of various materials. This technique effectively reduces thermal damage and material deformation, making it suitable for precision machining and high-quality cutting applications.

Advantages of Water-Assisted Laser Technology

• Reduced Heat Impact: Water jet lowers risk of material heat damage.
• Less Deformation: Cooling minimizes thermal-induced deformations.
• Ablation and Splatter Reduction: Water jet washes away molten particles, reducing surface damage.
• Versatility: Suitable for diverse materials, including hard alloys.
• High Precision: Achieves smooth, precise machining surfaces.

Disadvantages of Water-Assisted Laser Technology

• Complex Setup: Requires additional components, increasing complexity and maintenance.
• Material Limits: Effective on materials with specific thermal conductivity.
• Slower Speed: Coupling water jet and laser slows processing.

Advantages of Traditional Laser Technology:

• Wide Application: Established use in cutting, welding, marking, and more.
• High Processing Speed: Faster for efficient production.
• Material Adaptability: Versatile across various metals and non-metals

Disadvantages of Traditional Laser Technology:

• Heat Impact: May cause heat-related damage, especially in sensitive materials.
• Limited Precision: Precision affected by heat and optical constraints.

• Precision Cutting: Suitable for intricate and precise cutting tasks.
• Hard Materials: Processes hard and brittle materials like ceramics and alloys.
• Sensitive Materials: Ideal for heat-sensitive materials due to reduced thermal impact.
• Surface Cleaning: Used for precise cleaning and preparation of surfaces.
• Medical Devices: Applied in manufacturing medical instruments and implants.
