Laser Cutting: A Brief Overview

laser cutting

Laser cutters are tools that allow for precise cuts in materials using a laser beam. Typically, laser cutting is an industrial application that makes use of a carbon dioxide laser to cut materials. However, it is now starting to be utilized by hobbyists, smaller companies, and educational institutions. In fact, laser cutting works most often through infrared optics. This type of optics allows for the cutting and polishing of layers of either plastic or metal using a focused laser beam.

The laser is usually set on its setting for a very precise level of light. The object that is to be cut is placed inside a chamber and a beam of laser is directed at it. When the beam of light touches the material, a phenomenon called “hot cutting” occurs. The light is absorbed in the substance and the gas becomes dry. The chamber is then filled with a pressurized gas such as a simple argon, making sure that only the exact amount of laser energy is used to cut the material.

The laser cutting process is not that complicated. If you have done any research on the subject, you will find out that there are basically four steps involved in the laser cutting of material. The first step is the removal of air from the chamber. Once this has been done, the next step involves direct contact of the laser beam with the material.

The third step is cooling of the chamber. The laser cutters are cooled down after passing through an inert gas such as argon. After this step is done, the cutters are guided by a computer program onto the piece of material to be cut. A laser torch is then used to drive the cutters across the material, effectively cutting it. This is an extremely fast process and can take only a few seconds.

When it comes to safety, there is actually very little to worry about when it comes to laser cutting. Since the cut is done by a laser, there is no danger in terms of the material getting overheated or burned. In fact, you are even safe from the possibility of the material being fused due to high temperatures. Also, due to the fact that this is done digitally, there is very little chance that there will be any data loss in the event of an accidental cut.

In terms of the cost, this is actually quite affordable. Prices for these systems can range anywhere from a few hundred dollars to thousands of dollars, depending on what the system is and how complex it is. Basically, they are not that expensive at all and certainly fit into the budgets of many people. With the advances in technology, you will find that this is an increasingly popular method of cutting materials for almost everything. Whether you need to cut metals, plastics or paper, there is no reason why you should not use one of these systems when dealing with your projects.
