Laser Cut
In spite of the fact that metal cutting work traditionally employs manual or mechanical processes, laser cutting can be a very effective, viable and at the same time very cost-efficient option for the metal fabrication. When we talk about Laser equipment they are basically distinct from the other cutting machines in both application and design.
A laser device onto a very precise area of workpiece fires a very concentrated stream of photons in order to trim excess shape and material of the workpiece into a specific design. These types of machines are very effective in cutting the various grades of steel, such as stainless and carbon steel.
Types of Lasers
When it comes to Laser technology, it has many unique attributes that basically affect the quality of its cuts. The level to which light curves around surfaces is known as diffraction, and in many different cases lasers also have very low diffraction rates that enables higher levels of light intensity over longer distances. Additional features includes monochromaticity that determine laser beam’s wavelength frequency, and coherence basically measures continuous state of electromagnetic beam. These factors also vary according to different types of lasers used. The two most common types of industrial laser cutting systems are:
Nd:YAG: The neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is composed of a solid crystal substance that focuses light onto its target. It can also fire a rhythmic or continuous infrared beam that can easily be enhanced by secondary equipments such as diodes or optical pumping lamps. This laser cutting system is very efficient for the low-powered operations, such as trimming thin gauge steel or cutting sheet metal.
CO2: A carbon dioxide laser is a very powerful alternative to Nd:YAG and this laser uses a gas medium as an alternative of crystal for focusing light. Output-to-pumping ratio allows it to fire very high-powered continuous beam that is capable of efficiently cutting thick materials. Due to its high cutting strength, this laser is capable of basically shaping bulky steel plates up to 25 millimeters thick, as well as engraving and cutting thinner materials at lower power.
