What is Laser Cutting

Laser cutting is a way to cut precise patterns in metal, plastic, wood, and practically every other material that man works with. It allows a level ofA typical process laser has a beam about a 1/5 of a millimeter in width, focusing 1000 to 2000 watts of energy. This is enough to melt most common materials. Because lasers become less focused and lose energy as they penetrate through a material, there is a limit of about 20 mm for the deepness of the cut. 

Laser cutting machines are integrated into a larger CAD/CAM (computer-aided-design, computer-aided-manufacturing) system that takes a design file and implements it on a workpiece. These Laser cutting machines represent a stepping stone in the continuing trend away from hands-on manufacturing, putting human workers in a more removed, creative design role.

Because a laser is made up of photons, parts of its energy can be reflected away by materials such as aluminum and copper alloys. These materials are also thermal conductors, meaning they distribute incoming heat more evenly throughout their volume. For this reason, carbon alloy and stainless steel are popular workpiece materials for laser cutting. They are poor at absorbing heat, so heat is concentrated into the laser's path more readily.

Typical laser cutters allow features as small as 1 mm in size. Specialized lasers often feature sizes that are even smaller, allowing the fabrication of true micromachinery. The first laser cuts were made in 1967, as part of a spin off of a military research project focused on lasers. Because the beams used in cutting are "class 4" lasers, the machines are designed to ensure that human operators are never exposed to them directly. All the cutting is done inside the machine.

Although the development of China laser cutting industry is a preliminary development, it has completed a leap forward under the leadership of international science and technology, and has a higher stage of prominence than the same quality. In terms of laser cutting machines, the market demand is as high as tens of millions, adding new vitality to the broad market. Since the birth and application of the first laser equipment in the 1960s, many experts in my country have made efforts in the laser industry, and have reached a small international difference. At the same time as the development of the laser industry, complete sets of laser industrial equipment have also entered the production market, getting rid of the long-term dependence on foreign countries and solving the embarrassing situation of the domestic laser industry.

The rapid development of the domestic economy has become a high-industrial pillar of the laser market, and can reach an annual growth rate of more than 20%, becoming a new starting point for the global laser market. In the future, it can be doubled to expand the market of laser cutting equipment to the greatest extent, fill the domestic gap, and get rid of the trapped state of domestic high-end laser equipment and become a pillar in the world. At present, the domestic laser industry is mainly concentrated in Shenzhen and Wuhan, of which Shenzhen is an important domestic sales market, and with years of development experience, it leads other regions.
