2. Material Setup: The metal sheet is placed on the cutting table and positioned accurately.
3. Laser Activation: The laser beam is focused onto the surface of the metal, creating intense heat that melts or vaporizes the material.
4. Assist Gas Application: Assist gas clears away the molten material, allowing for a clean, smooth cut.
5. Cutting Completion: Once the desired shape is achieved, the cut pieces are removed for inspection and any necessary post-processing.

3. Types of Laser Cutting Machinery: Fiber vs. CO2

Choosing the right laser cutting machinery depends on various factors, including material type, толщина, and the required level of precision. Here’s a breakdown of the two primary types of laser cutters:

Fiber Laser Cutting Machinery

Fiber laser cutting machinery is known for its high precision and efficiency. It uses a solid-state laser amplified through optical fibers, which provides several benefits:
– Smaller Beam Diameter: Allows for fine, intricate cuts, making it ideal for detailed designs.
– Effective on Reflective Metals: Fiber lasers excel in cutting metals like aluminum, латунь, and copper due to their shorter wavelengths, which are better absorbed by these materials.
– Энергоэффективность: With a higher electrical efficiency, fiber lasers can reduce operating costs over time.

CO2 Laser Cutting Machinery

CO2 laser cutting machinery uses a gas mixture, primarily CO2, to generate the laser beam. It’s often chosen for its versatility across different materials:
– Broader Beam: This makes CO2 lasers effective for cutting thicker materials, though they may lack the precision of fiber lasers for smaller details.
– Versatile Material Handling: Capable of cutting a variety of non-metallic materials such as wood, акрил, and textiles.
– Lower Initial Investment: Generally, CO2 lasers have a lower upfront cost, making them accessible to businesses with budget constraints, though their maintenance requirements can be higher.

4. Advantages of Laser Cutting Machinery

Laser cutting machinery has become the preferred choice for manufacturers due to its numerous advantages. Here are the key benefits:

Superior Precision and Tolerance

Laser cutting machinery achieves extremely tight tolerances, crucial for industries that require high precision, such as aerospace and medical devices. The ability to produce consistent and accurate parts minimizes waste and ensures perfect fits, reducing the need for adjustments during assembly.

Enhanced Speed and Productivity

Laser cutting is significantly faster than traditional cutting methods, especially when dealing with thin metal sheets. This speed allows manufacturers to meet tight deadlines and handle large production runs with ease. By reducing cutting time, laser machinery increases overall productivity, which is particularly valuable in high-demand industries.

Minimal Finishing Required

One of the standout benefits of laser cutting machinery is the quality of the cut edges. The laser produces smooth, края без заусенцев, minimizing the need for additional finishing work such as grinding or sanding. This not only saves time but also reduces labor costs.
