Sandpaper cutting

A sandpaper manufacturer needs to cut discs of different shapes and sizes from sheets of sandpaper to fit a range of sanding tools.  In addition, the discs must be perforated with dust extraction holes, which improve the performance and prolong the life of the sanding discs.  For these processes CO₂ laser cutting offers numerous advantages over traditional die cutting methods.

The non-contact laser process causes no deformation of the abrasive surface, and there is no tool wear.  Laser cutting is flexible with no hard tooling needed, and it produces perforated hole sizes and complex patterns which exceed the capability of a die cutting machine.  The laser-cut edges are smooth with a good finish.  The CO₂ laser is usually integrated with a galvanometer scanner, which allows both cutting and perforating operations to be carried out in a single automated process.
