Tips for High Precision Engraving and Cutting

Maintaining high levels of precision during laser engraving and cutting involves several critical considerations. Here are five tips that we believe will help you:

• Select the Right Material

Various materials react differently to laser engraving and cutting. Take acrylic, for instance: It cleanly melts and gives smooth edges. In contrast, wood burns and may require additional sanding after being cut. Ensure that the material fits within the cutter’s specifications, as incompatibility may lead to unwanted artifacts during output.

• Calibrate the Focus of the Laser

Well-focused lasers yield flawless and smooth cuts. Almost all CNC laser cutters have a focus tool that adjusts the distance between the laser head and the workpiece for the best cut. Skewed focus will engrave blurry images, while cuts will be incomplete, if performed.

• Adjust Power and Feed Rate Accordingly

The speed of the laser must also be proportional to the power settings during cutting: higher power should be applied with a slower cutting speed. For example, slower speeds work better when the power is cranked up, especially when working with thick materials, and lower power with faster speeds is desirable for fine engravings. Always test scrap material to ensure balance before starting the actual project.

• Care of Laser Lens and Mirrors

With time, dust and other particles can obstruct the laser beam’s ability and accuracy due to power loss. The appropriate steps must be taken to clean the components and check for damages or signs of wear periodically.

• Air Assist and Ventilation

During the operation, proper ventilation, along with air assist systems, helps reduce smoke and grime that otherwise would reduce the quality of engraving and cutting. Not only does air assist help get rid of debris from the laser, but ventilation also stops the equipment from overheating while providing fresh air to the work area.

These suggestions help users maintain their equipment while achieving precise, quality engravings and cuts.
