Advantages of Precision Laser Cutting

  • Remarkable Precision

    Materials cut with lasers exhibit superior accuracy and edge quality compared to those cut using traditional methods. Laser cutting employs a highly focused beam, serving as a heat-affected zone during cutting, which minimizes thermal damage to adjacent surfaces. Additionally, the use of high-pressure gases (typically CO2) in the cutting process results in cleaner cuts, removing excess material from narrower workpieces and delivering smoother edges. Integrated CNC components facilitate automation, providing a more intuitive operation.

  • Enhanced Workplace Safety

    Workplace accidents involving employees and equipment can have a negative impact on a company's productivity and operational costs. Material processing and cutting operations, including cutting, are accident-prone areas. Using lasers for these applications reduces the risk of accidents. Since it's a non-contact process, it means that the machine doesn't physically interact with the material. Additionally, the generation of the laser beam doesn't require any direct operator intervention, keeping the high-power beam securely enclosed within a sealed machine. In most cases, apart from inspection and maintenance operations, laser cutting doesn't require human intervention, minimizing the potential for employee accidents and injuries compared to traditional cutting methods.

  • Greater Material Versatility

    In addition to cutting complex geometries with higher precision, laser cutting allows manufacturers to cut various materials without the need for mechanical adjustments, offering a broader range of thicknesses. Using the same beam with different output levels, intensity, and duration, laser cutting can cut a wide variety of metals with similar adjustments, ensuring higher precision and stricter tolerances. Integrated CNC components facilitate automation, providing a more intuitive operation.

  • Faster Delivery Times

    The time spent on setup and operating manufacturing equipment increases the overall production cost for each workpiece. Utilizing laser cutting methods reduces the total delivery time and the overall production cost. Unlike traditional cutting methods, laser cutting doesn't require mold changes and setups between materials or material thicknesses. Setting up a laser cutting process involves more machine programming than material loading. Moreover, using laser for the same cuts can be up to 30 times faster compared to traditional saw cutting.

  • Lower Material Costs

    By utilizing laser cutting methods, manufacturers can minimize material wastage significantly. The focused laser beam used during the cutting process generates narrower kerfs, reducing the size of the heat-affected zone and the quantity of unusable materials. When working with flexible materials, deformations caused by mechanical machine tools increase the quantity of unusable materials. Laser's non-contact cutting eliminates this issue, enabling cutting with higher precision, stricter tolerances, and reduced material damage in the heat-affected zone. Allowing parts to be placed more closely on the material reduces material wastage, lowering material costs over time.
