Galvo & Flatbed - What's the Difference?
The biggest difference between a flatbed laser and a galvo laser is how the laser beam itself is directed onto the workpiece. With a flatbed laser, the beam moves along the x axis and y axis with the help of fixed mirrors. This then results in the laser beam focusing and pointing vertically onto the workpiece. The bigger the machine, the bigger the processing area.
A galvo laser beam is directed onto two highly dynamic, rotatable mirrors of low inertia. These move with galvanometer drives, which is where the name 'galvo' comes from. Hardly any masses are accelerated this way, so the laser beam can be directed over the workpiece at a very high speed with high precision and consistency. The marking field is defined by the deflection angle and focal length of the machine's optics.
