Everything You Need to Know About Laser Cutting

When it comes to cutting metal, glass, wood, and other hard exteriors, it is difficult to imagine a beam of light able to keep up with a rotating blade. A traditional beam of light would have a difficult time. That said, a concentrated laser beam creates cutting a breeze.

What Is Laser Cutting?

Laser cutting is a method in which a laser beam is used to heat a workpiece to the point where the piece is cut with precision. In fact, laser cutting machines embrace a high-powered laser and a computer to direct the laser beam over the material to be cut. From there, the laser beam melts, burns or vaporizes the material along the predetermined cutting line, resulting in a precise and well-cut edge.

Laser Cutting Applications

Laser cutting machines is used by manufacturers, small businesses, amateurs, and schools the same. In general, the common elements suitable for the laser machine include:

Fine non-metallic materials

Paper, most plastics, Mylar stencils, polycarbonate, fabrics, the wood of up to .04 inches and also thin acrylics may be cut with an average power laser of 150 watts (maximum power of 450 watts).

Thicker non-metallic materials

You will need a laser with an average power of between 250 watts to 500 watts (up to 1500 watts maximum power) to cut thick non-metallic materials, such as thicker plastics and wood up to an inch thick. On the whole, lower power lasers will have to work harder to prepare the same cut. And this moderates the cutting speed and can cause extreme heat, damage or chemical changes to the Heat Affected Zone.

Metallic materials

In general, metallic materials require higher power lasers (between 150 watts and 1,000 watts (up to 2500 watts maximum power). A few thin metals can be cut with 150-watt lasers when oxygen-assist gas is used, such as stainless steel or cold rolled steel.

Laser cutting is generally used to cut any number of items from a variety of materials, such as watch faces, puzzles, metal tags, machinery parts and components, patterns, packaging, signs, leather upholstery pieces and more.

Advantages of Laser Cutting

The laser cutting machine provides a lot of benefits over other types of cutting. Not only can you cut a variety of materials such as paper, cardboard, plastics, metal, and leather, the laser is tremendously accurate. Just the once a pattern is programmed into the laser cutter, it can constantly cut particular copies of the pattern on the workpiece after the workpiece. On the other hand, the edges cut with laser are usually clean. In addition to cutting items, the laser can similarly cut small, highly detailed holes with great edge quality.

In the end, the laser beams do not wear out because of cutting, which brings about in less strain on the cutting equipment. The laser cutting machines has reached the age of majority and has proven to be a reliable and advantageous alternative to other cutting processes.
