Adjusting the settings on a CO2 cutting laser varies the quality and finish of the cut, i.e., making it coarser or finer. You can reduce the power for thinner or less robust materials, as well as slow the cutting speed to prevent burning at the edges of cuts.
Because the cutting beam focuses to a pinpoint, there is far less kerf than you would get with a standard steel blade. While the kerf is minimal, it is still wise to leave a couple of millimeters spare between the parts while marking them on the sheet.
Most industrial processes involve the laser beam passing all the way through the material, separating it into two pieces. However, the laser can be adjusted to create a partial cut, and is used in two common methods of engraving:
Vector engraving – the laser beam engraves an outline.
Raster engraving – the laser ‘prints’ an infill engraving.
CO2 laser cutting can be used to cut or engrave materials as diverse as paper, plywood, and acrylics. In fact, CO2 laser cutting stainless steel is very prominent in the fabrication industry. Metals are worked using industrial-sized CO2 cutting lasers.
CO2 laser cutting allows a quick turnover of bespoke design parts at very low cost. Prototype parts can be produced, tested, and turned over for high-volume manufacturing, in the space of a day. CO2 laser cutting is an indispensable manufacturing process for most fabrication jobs. Contact one of our representatives to learn more about our laser cutting process.
Fiber lasers are easy to use and very reliable, with minimal overhead. There are no expensive mirrors and lenses to set up and maintain. In fact, the fiber laser cutting machine is almost maintenance-free.
They are also more optically and electrically efficient. Not only does this mean that most of the power generated goes into cutting the metal, but less gets converted into waste heat. Consequently, less water cooling is required. A fiber laser consists of up to 80% of its power input, a much higher efficiency than either gas or crystal lasers.
Many industry sectors are now switching to fiber laser cutting because of the faster processing times it offers. New fiber laser metal cutting machines are combining ever higher power output with reductions in energy input. This is leading to cheaper commercial runs and prototyping.
