Laser cut sign

When it comes to cutting metal, wood, glass, and other hard surfaces, it's hard to assume a beam of light to be able to match a spinning blade. A normal beam of light would indeed have a difficult time. That said, a focused laser beam makes cutting a breeze. Laser cut sign

What's Laser Cutting?

Laser cutting is an activity in which a laser beam is employed to heat a workpiece to the stage where in fact the piece is precisely severed. Based on Answers.com, laser machines include a high powered laser and a pc to direct the laser beam onto the material to be cut. From there, the laser beam melts, vaporizes, or burns the material over the predetermined cut line, producing a precise, neatly cut edge. Laser cut timber

Based on Coherent, an organization that manufactures laser cutting machines, laser cutting:

"... concentrates high levels of energy in to a small, well-defined spot. The resulting heat energy developed by the laser vaporizes materials in this small-defined area and a gas, or mixture of gases, such as for example oxygen, CO2, nitrogen, and/or helium is employed to blow the vaporized material out from the kerf (the width of a groove made by the laser beam). The beam's energy is applied directly where it's needed, minimizing the Heat Affected Zone (HAZ) surrounding the location being cut."

Laser Cutting Applications

Laser cutting is used by manufacturers, small businesses, schools, and hobbyists alike. Based on Coherent, common items suitable for laser machine include:

. Thin non-metal materials - Paper, most plastics, fabrics, mylar stencils, polycarbonate, wood up to.04 inches, and thin acrylics may be cut with a 150 watt average power (450 watt peak power) laser.

. Thicker non-metal materials - You will need a laser with an average power of between 250 to 500 watts (up to 1500 watt peak power) to cut thicker non-metal materials such as for example thicker plastics and wood up to 1 inch thick. In general, lower power lasers will need to work harder to make the same cut. This reduces cutting speed and may result in excessive heat, chemical changes, or damage to the Heat Affected Zone.

. Metal materials - Metal materials generally require higher power lasers (between 150 and 1,000 watts (up to 2500 watt peak power). Some thin metals (such as metal or cold rolled steel) may be cut with 150 watt lasers when oxygen-assist gas is used. Know more

Laser cutting is employed to cut numerous items from a number of materials such as for example: jigsaw puzzles, clock faces, metal tags, machinery parts and components, packaging, signs, patterns, leather upholstery pieces, and more.

Features of Laser Cutting

Laser offers numerous advantages over other types of cutting. Not only will you cut a number of materials such as for example paper, plastics, cardboard, leather, and metal, laser is incredibly precise. Once a routine is programmed into the laser cutter, it may continuously cut exact copies of the pattern on workpiece after workpiece. Laser cut edges are clean. Along with cutting items, laser also can cut small, highly detailed holes with good edge quality.
