Precision Laser Cutting

Laser Cut Parts:

Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications. Laser cutting works by directing the output of a high power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high quality surface finish. Our laser cutters are used to cut flat-sheet material.

Great Lakes Engineering employs computer-controlled Lumonics Screen Cut™ lasers and a Tannlin T8-SPS to cut stencils and thin foil parts to extremely high tolerance. The process is more precise, faster, and cleaner than chemical etching. It also requires little if any post-manufacturing processing and poses fewer direct environmental concerns.

Many of the same products can be manufactured using different processes. Great Lakes Engineering has the experience to determine which process is appropriate for the application, tolerances, longevity, durability and cost.

Materials: Stainless Steel, Titanium, Nitinol, Nickel, Datum Alloy, Invar, Kovar


  • Reduced part distortion as a result of a small Heat Affected Zone (HAZ)
  • Improved and efficient part nesting due to narrow kerf width and programming flexibility
  • Enhanced cutting ability due to narrow kerf width
  • Improved tolerances
  • Incredible part production repeatability and accuracy from computer generated repetition of motion
  • Virtually zero machining damage created by burr on the bottom side of material improving product quality and minimizing secondary polishing or finishing requirements due to the laser process’ ability to regulate the feed rate, assist gas ratio, and regulate power
  • Virtually no part damage on delicate parts due to the fact that laser cutting is a non-contact process
  • No tooling required
  • Improved yield
  • Small runs and large run capabilities – without tooling charges
  • Ability to perform rapid design changes due to programming flexibility
  • Increased utilization of materials
  • Greatly reduced setup times
  • Easily adaptable to production needs
  • Decreased risk of injury compared to other manufacturing processes
  • Decreased noise
  • Environmentally safer and cleaner due to lack of chemistry
