Pushing the Solid-State Laser Speed Limit

Pushing the solid-state laser speed limit.

Solid-state lasers theoretically could cut through thin sheet at up to 1,000 meters per minute, though no machine in the world can drive a laser at that speed. But new approaches to laser cutting are bringing laser cutting speeds closer to the theoretical maximum.

In the early days of laser cutting, the machine had no trouble keeping up with the capabilities of the beam. A low-powered CO2 laser could cut only so fast without creating problems with edge quality and incomplete penetration. The basic Cartesian positioning system, driven by a ball screw, crept along. Back then the mere fact that light could blank out a sheet metal part, without a hard tool, was enough to make economic sense.
