Things to know about laser cutting

Laser cutting is the process in which a pattern is made by exposing a metal object to an intense beam of light that cuts the material. Laser cutting is also called as laser engraving, and it is a very common procedure where many objects are cut by using laser technology. Laser cutting usually uses the high-energy light emitted by a laser light guided by thin optical fibers or mirrors. Depending upon the type of laser used, you can cut various kinds of materials including metal. The metal that is cut by laser can be of various types like aluminum, stainless steel, titanium, carbon fiber, plastic etc. Go now to know more about laser cutters.

With the development of new laser technology, many new products have been introduced into the market. The laser cutting machines have been developed to perform a variety of functions such as metal fabrication, surface fabrication, jewelry design et al. In the industrial sector, there are several applications of laser technology. One of them is the heavy duty industrial machines like Sanders, saws, drills, CNC plasma torches, CNC laser cutting machine, polishers, and so forth.

A laser cutting machine is also used for the production of intricate designs like furniture, die cuts, metal casting, aircraft models, and so on. These machines give the capability to cut out any kind of detailed work piece with ease and thus enabling the workpiece to be produced in a desired manner. The workpieces that are produced by these machines are usually of high grade and are usually required in several industries. They are used for several applications such as wood working, metal working, automotive, and even dental work.

A laser cutter is generally made up of three major parts namely the laser resonator, the laser source, and the cutting head. The laser resonator consists of a set of micro-electromagnets that are responsible for generating an electrical field that precisely maintains the voltage between the cutter and workpiece. The electrical pulse produced by the resonator activates the cutting head. This head then utilizes a nitrogen injector to inject a stream of nitrogen gas. The nitrogen in the stream causes a vapor to form at the work piece interface with the cutting medium thereby literally “sealing” the workpiece into the cutter.

When the laser cutting machine cuts through the material, the gasses created are vented outwards through the cutters’ exhaust port. These gasses, in turn, act as a coolant that causes the plastic or other material to freeze and contract. As the laser cutting speed increases, the workplace begins to solidify because it no longer can absorb laser light but rather must actively emit laser light in its direction of movement. Increasing the cutting speed further solidifies the material thus completing the cutting process.
