How Laser Cutting Works
Before we start exploring the subject of laser cutting in more detail, let’s first pause to explain how laser cutting and laser cutting processes actually work.
Laser cutting utilizes a laser beam to cut or engrave materials. This process involves the output of a high-power laser being directed through optics. The laser beam is first directed onto the material’s surface. The intense heat from the laser beam then melts, burns, or vaporizes the material along the cutting path. This results in an accurate edge with a high-quality surface finish.
Types of Lasers
There are two types of lasers most commonly used in GCC LaserPro laser cutting, these include:
CO2 Lasers
CO2 lasers are powered by a combination of electricity and a gas mixture that contains CO2. These lasers operate at a wavelength of 10.6 micrometers, and are typically used on non-metallic materials.
Uses of CO2 lasers:
- Cutting
- Engraving
- Marking
- Drilling
- Usually used on wood, acrylic, plastics, foam, paper, and textiles.
Fiber Lasers
Fiber lasers use optical fibers doped with rare earth elements such as erbium and neodymium to generate a laser beam. Fiber lasers operate at a wavelength of 1.064 micrometers. These high-power lasers are known for their ability to cut through thicker materials.
Uses of fiber lasers:
- Cutting
- Engraving
- Marking
- Drilling
- Usually used on metals such as stainless steel, brass, and aluminum.
Laser Cutting Components
Now that we’ve described what a laser cutter is and the two main types of lasers used in GCC LaserPro laser cutting, it’s time to take a closer look at the workings of the laser cutter.
First, let’s examine the components used in a laser cutting system. A laser cutting system consists of the following main components:
Focusing Optics
The laser cutter’s mirrors and lenses are its focusing optics. The mirrors and lenses ensure accurate laser cutting by directing the laser beam to the precise focal point that needs to be cut or engraved.
Motion Control System
A Closed-loop DC servo motor can deliver greater continuous shaft power at higher speeds than a stepper of the same frame size. In addition, It can also give far greater accuracy due to closed-loop position feedback and the continuous movement, instead of constant stopping and starting.
Material Handling Mechanisms
The material handling mechanisms of the laser cutter include its rotary chuck and film clamping device. These components position and move the material to ensure optimum stability and position during the laser cutting process.
Each of the above components has a crucial role to play in the highly intricate and precise process of laser cutting.
The components work together as follows to cut materials precisely:
- First, the laser beam is produced by stimulating the lasing material within a closed container. The mirrors or fiber optics then direct the laser beam at the workpiece.
- Next, the beam makes contact with the material and heats it to either melt, vaporize, or burn (depending on the requirements of the job).
- High-pressure gas blows away the excess material to ensure a perfectly clean finish.
Advantages of Laser Cutting
Laser cutting is a widely used technique. Laser cutting technology continually evolves at a rapid pace bringing with it exciting developments that benefit the end-user. Here are its main advantages:
