Laser Cutting Vs. Waterjet Cutting

When it comes to laser cutting versus waterjet cutting, there are numerous debates. The fact is that both options have their own level of advantages that they can provide the user. But having said that, you should know what is best for you before starting a job. Whether you do not, you can end up with under average results or pay more money than you should. Therefore, to avoid this, knowing the advantages of both cutting methods will save you long-term time.

Waterjet Cutting Technology

When it comes to cutting metal, there are several ways to complete the task. Several are as easy and rough as a hacksaw. Others are more technical, such as laser and plasma cutting tools. The drawback of all these is that there are disadvantages. These range from the heat that reasons deformities along the cutting line to the rough and neglected edges that remain. This is where the cut by waterjet intervenes. This method has several advantages over others and now I will explain those advantages.

  • No Heat

Unlike other methods, waterjet cutting doesn’t make the heat they produce. This means that it does not melt, distort or deform along the edges that help when trying to make precise cuts for complex pieces.

  • Precision

Waterjet cutting devices can have amazing accuracy. This technology offers the possibility of making precision cuts with tolerances of up to ± 0.005. “Currently, this is not cheap, since the more precise the cost in the configuration of the cutter and the materials needed to make a precise cut but it is doable.

  • Clean Up and Time

Another good advantage of this technology is cleaning. As it does not leave scum and there is little or no burr on the parts. There is little required for cleaning or secondary finishing operations like sanding or grinding. This prepares the cuts to move faster and lets jobs to be completed quicker than with other technologies. Read more!

Laser Cutting Technology

This is a technology that uses a laser beam to cut precise patterns in all kinds of materials such as plastic, metal, and paper. It is a type of subtractive manufacturing process that cuts a portion of digital design into another piece of sheet material. The laser cutting process is described as well as the direction of an efficient high-power laser in the material that leaves a polished edge with a high-quality finish.

Valuable Benefits of Laser Cutting

This technology is an advanced procedure that produces ideal virtual cuts at any shape and angle with the assist of materials fragmented by cutting tools. Below are some of the benefits of this technology:

  • Very sharp edge definition
  • Flat blade cutting
  • Ability to cut corners, 3-dimensional shapes, complex holes and slots that have high repeatability
  • Five-axis and six-axis laser control
  • Ultra low distortion
  • Fine cutting width
  • Minimum cutting width
  • Zero variations due to wear of the tool
  • Cutting lubricants are not required
  • Low thermal input
  • Narrow zone affected by heat
  • No mechanical force in the workpiece

Which Cutting Method Works Best?

The best cutting method depends to a large extent on the required capacities. If a job involves a piece of metal 1 ” less or thick and requires moderate to exacting tolerances, not anything beats a laser cutter. If a workpiece is prepared of an exotic material that has low heat tolerance, then it is likely that a waterjet is your best choice. If the material is metallic and very thick and speed is critical, then plasma cutting would be the best. For more details, visit:
