Engraving is a neat way to write messages, names, dates, and other memoirs into metal or wood surfaces. Doing this for someone with a memorable message or date that means a lot to them can go miles for a great gift. Engrave anything from a watch, a metal armband, maybe even a plaque. The possibilities are practically endless, which is great because that leaves plenty of room for gift ideas!
Process In Detail
Laser Engraving, which is used today as an easier form of engraving that does not require the cutting of metals or plastics using tools, but instead it uses a high powered laser. Laser Engraving is the practice of using lasers to engrave an object. Usually, a large machine or unit is used to engrave a certain piece of material with a design specified by the person operating the machine. It consists of three main parts, a laser, a controller, and a surface. The laser is almost like a pencil, the beam emitted from it allows the controller to trace patterns onto the surface. A laser can remove material efficiently because the laser beam can be designed to deliver energy to the surface in a manner which converts a high percentage of the light energy into heat. Because of the efficiency of the beam, the laser may heat up rather quickly. In turn, elaborate cooling systems are required for the laser, but to keep things cooler and running longer the beam may be pulsed to decrease the amount of excessive heating.
Different patterns can be engraved by programming the controller to traverse a particular path for the laser beam over time. The trace of the laser beam is carefully regulated to achieve a consistent removal depth of material, for example criss-crossed paths are avoided to ensure that each etched surface is exposed to the laser only once, so the same amount of material is removed. The speed at which the beam moves across the material is also considered in creating engraving patterns. Changing the intensity and spread of the beam allows more flexibility in the design.
Materials that are perfect for engraving are anywhere from wood to plastics. The thing with wood though, lasers do not require much power to etch into wood, however with hardwoods like walnut and mahogany can handle a bit higher power of laser. Softwoods tend to vaporize at less consistent depths, so a fan may be required to put out material that is trying to ignite. With plastics, special materials had to be created to divert heat away from the etching area to prevent melting of the material. Metals started out being the best traditional engraving materials, but turned out to be the most difficult to engrave. Each metal has unique properties, such as resistance to chemicals or certain temperatures or even high resiliency, for example stainless steel is used frequently for aerospace parts and components due to its tensile strength and durability.
