Laser Engraving

Co2 CNC laser engraving is ideal for both engraving and for cutting holes or shapes. CNC laser engraving allows for much finer marking and cutting than CNC milling. Depending on the type of laser used, a laser will either vaporise the material at which it is pointed, or it will change the material surface creating a contrast.
Lasers can engrave wood, rubber, glass and plastics (including Perspex) as well as natural materials such as slate, marble and granite.

By managing the output power of the laser, its pulse rate and the speed the laser moves over the surface, the cutting or engraving effect can be precisely controlled for each specific material. By reducing the power to a minimum, very thin materials can be engraved or cut.

When the laser is unable to remove the surface of a particular material, such as stainless steel, a chemical layer is sprayed onto the surface first. When the laser comes in contact with the chemical layer, the chemical is fixed to the material. The excess spray is then rinsed off leaving a permanent black image on the surface.
