Laser cutting technology has become very popular. It is regarded as viable for precision cutting of a broad range of materials in desired shape and size. It is an innovative approach or state-of-the-art method used in cutting of hydro-formed tubes and parts, thick-section materials, and thin sheet metals in an accurate manner.
This technology has lots of advantages over the traditional plasma cutting. The laser cutting service offers preferred cutting without deforming or hampering the work-piece. Manufacturing sectors and multifarious industry widely use laser beam cutting technology. Materials that are cut include plastics (ABS, Mylar, Lucite, Acrylics, Styrene, and Kapton tape). Other include wood products (wood picture frames, furniture, and wooden jewelry), and XPS foam for Depron foam, RC planes, and many more.
How it Works
A laser beam of high density is generated from a laser source and directed to the workpiece using mirrors positioned in distinct positions. The beam is concentrated by a lens to a particular spot on a surface of a material to be cut. The beam quickly melts the
workpiece. Desired cutting gas known as assist gas is applied to cool and protect the focusing lens.
Types of Laser Cutting
Laser cutting can be classified into two depending on cutting gas used: cutting with oxygen as the assist gas heats the material to ignition temperature. The material gets burned and vaporized.
Secondly, you can cut with non-reactive gases. In this method, the workpiece melts as a result of laser beam intensity. No additional heat is generated during the process as non-reactive gases do not react with melted material.
Laser cutting has several advantages over the traditional plasma cutting. For instance, it is a suitable method for intricate part cutting. There is a minimal distortion of material as less area is affected by the heat. After the cut, there is no need of secondary finishing operations. This is because of high-grade overall finish, and minimal part distortion. It is also possible to custom built advanced laser systems for specialized tasks. These cutting processes are more precise and faster as compared to other cutting processes. The cutting process is CNC controlled and therefore you can close nesting of parts. This will reduce material wastage.
Nowadays, there are leading and reputable companies, which offer laser cutting services to any given industries. Using advanced systems different materials can be cut. Some of the common materials cut include super alloys, tungsten, nickel, steel, brass, ceramics, rubber, copper, brass, and aluminum.
