Laser Engraving

The Robot ® K600 can help you with a variety of industrial laser system engraving applications. The Robot ® K600 has a high quality CO2 lasers to facilitate your laser engraving application. Contact an Hi Image Enterprises to discuss your particular application.

Typically, engraving on almost all materials is done by using a two tone ("posterized") process, similar to that used to print black and white photos in newspapers. True "gray scale" engraving is not used because the output power of CO2 lasers is not stable enough over a sufficient period of time to avoid tonal differences in the image (the most common effect is called "banding"). The Robot ® K600 uses images that are black and white bit maps (BMP files) and is capable of grey scale engraving if desired.

Wood:
Certain woods with the right grain can be very effective as an engraving medium, depending largely upon the type of image. Generally, fine grain hardwoods are used. Most wood engraving is done in a "raster scan" mode.

Marble:
Black marble is the material most commonly used for engraving images. This process is done with CO2 lasers ranging typically from 25 to 100 watts used in a "raster scan" mode. Higher power lasers allow for faster engraving times up to the point where the speed of the mechanical system limits maximum acceleration for the rastering process. Galvanometers can sometimes be used, depending upon the image(s) to be engraved; however, the maximum size of the engraved piece is usually limited to 150x150 mm (or thereabouts) and the resolution is somewhat reduced.

Plastics, Metals, and Other Materials:
Most plastics, metals, and other materials (paper, textiles) do not have a sufficient range of sensitivity to be engraved in a grey scale manner, and thus, a two tone process is used.

The Robot ® K600's 30 watt CO2 water cooled laser operating in raster mode is an excellent compromise. With it's high reliability and inexpensive operations, it will be a profitable addition to any engraving business.
