What is faster – laser cutting or water jet cutting?

The speed of laser cutting versus water jet cutting can vary depending on several factors, including the material being cut, its thickness, and the specific equipment and settings used. In general, both methods are capable of high cutting speeds, but they excel in different applications.

Laser Cutting:

  • Laser cutting is typically faster for cutting thin materials like metal sheets (up to around 0.5 inches or 12 mm thick) and non-metallic materials.
  • It uses a focused laser beam to melt, burn, or vaporize material along a predetermined path.
  • The cutting speed of a laser can vary depending on the power of the laser, the type of material, and the complexity of the cuts.

Water Jet Cutting:

  • Water jet cutting is well-suited for cutting a wide range of materials, including metals, plastics, stone, glass, ceramics, and composites.
  • It uses a high-pressure jet of water mixed with an abrasive substance (such as garnet) to erode the material.
  • Water jet cutting is generally slower than laser cutting for thin materials, but it can be more efficient for thicker materials (over 0.5 inches or 12 mm) and materials that are sensitive to heat.

Ultimately, the choice between laser cutting and water jet cutting depends on the specific requirements of the job, such as material type, thickness, precision needed, and potential heat sensitivity. It’s also worth noting that both methods have their own advantages and trade-offs, beyond just cutting speed, so it’s important to consider those factors as well.
