Advantages of using laser cutting equipment
Lasers aren't just for sci-fi movies and eye surgery; instead, they are also very useful in making precise cuts in high-density material like metal and stone. Laser cutters use a high-powered laser controlled by a specially designed computer to melt or vaporize material. Waste is blown away by a stream of gas, resulting in an extremely accurate cut.
The advantage of laser cutting machines over other cutting implements such as saws is clear: it reduces the potential for operator error and contamination from other materials. However, some drawbacks to keep in mind are the high energy required and the cost.
Types of Laser Cutter
There are at least three main kinds of lasers used in laser cutting equipment. The first, CO2, is used primarily for cutting, boring and engraving in high-density materials like metals and stone. The second kind of laser, neodymium, or Nd, is very similar to CO2 but is more often used in situations that require a lot of power and energy but low repetition. Finally, there's the Nd-YAG laser, for extremely dense materials where a boring or engraving operation requires consistent output of high energy.
How Laser Cutting Works
The laser cutting procedure, simply put, involves the use of a laser beam by sending short electrical discharges within a closed container. The stimulation produced by the lasing material causes a beam to be reflected internally via mirrors until it produces enough energy to escape as a stream of light. Mirrors direct that light to a designated work area, where the light pulses can effectively make an impression on different kinds of materials. Adjusting the power of this light can help determine its proper application.
Using a Laser Cutter
Laser cutters should only be operated by someone with training. When an operator receives the proper training (including safety training), they can use new or used laser cutters for a variety of different purposes, including wood processing, package printing, arts and crafts and even construction modeling. Because a laser cutter can make extremely precise cuts over a variety of sizes, it's often used in the electronic, construction and automobile industries.
