WE HAVE THE SOLUTION! OUR NEW 1500 WATT CNC-CONTROLLED LASER CUTTER IS
AT YOUR DISPOSAL
The Process
Laser technology is not new, but it is only recently that the full benefits have
become available to manufacturers.
Taking light and passing it through a series of lenses makes the light source
so great that its power density is several million times that of the sun - this
laser energy is then used to cut almost any material.
The light is directed down towards a CNC-controlled table making it very easy
