Laser for cutting, engraving or marking
The 150W CO² (carbon dioxide) laser we have at our disposal can do many different things. The device can perform for instance laser cutting, laser engraving or laser marking. The CO² laser can cut many materials, but not all of the exisinng materials. Due to the infrared wavelength of the Laser, this device cannot cut/even mark any metals, but for examplean glass can be engraved/marked. Our laser is mainly intended for sheet stock and as a result it has little of its own height adjustment, but on a case-by-case basis, something other than sheet stock can also be fitted there.
By cutting, different materials can be shaped. The laser can be used to cut fairly dimensionally accurate parts. The disadvantage of laser cutting is its slightly conical cutting pattern (the laser beam shrinks to the focal point and then expands afterwards + the laser also burns the material slightly sideways).
Upon engraving with a laser and an air jet, the material is removed, but not cut through the material. In this way, the piece is slightly three-dimensional by varying the depth of the engraving (adjusted, for example, by the cutting speed / power and how many times the spot is run).
When marking materials, the intention is not (necessarily) to engrave the text deep into the material. The laser can make a fairly nice impression on several substances. The mark in the material itself consists of charret material or material which has discolored due to the heat. The laser can be used to mark equipment, signs, or even remove paint or anodization from metal (ie text / image is left exposed from the coating).
