Laser cutting machine is a prototype and manufacturing tool, mainly used by engineers, designers and artists to cut and etch flat materials. The laser cutting machine uses a thin focused laser beam to penetrate and cut the material to cut out the patterns and geometric shapes specified by the designer.
In addition to cutting, the laser cutting machine can also heat the surface of the workpiece to rasterize or etch the design onto the workpiece, thus burning the top layer of the material to change the appearance of the grating operation.
Benefits About Fiber Laser Cutters
Fiber lasers cutting machines, normally we also call it laser cutter as well. It has several main advantages. The light propagating in the fiber shields the environment well, and the fiber laser is often designed very compact.
High effiency & power
They provide large gain bandwidth, wide wave-length tuning range and the ability to generate ultra-short pulses. They operate with high power and efficiency and are suitable for various types of cutting programs.
High speeds of fiber laser
Fiber lasers can penetrate thin materials at extremely high speeds. They can also cut reflective materials without the risk of damage to the machine caused by reflection, which makes copper, brass, aluminum and other metals can be cut without problems.
How Laser Cutting Machines Work?
There are several different types of laser cutting machines, but they basically use the same process of laser cutting materials.
1. The laser comes from a laser resonator, which emits a strong light to the cutting hair through the reflector system.
2. In the cutting head, the laser is focused through the lens and narrowed to a very thin and concentrated beam. The beam is projected downward onto the material, which can cut or rasterize the raw material.
3. The cutting head is usually installed on the so-called XY gantry, which is a mechanical system usually driven by belt or chain, allowing the cutting head to move accurately within a given rectangular area, which is the size of the workbench.
4. The gantry allows the laser head to move back and forth on the workpiece, so that accurate cutting can be carried out at any position on the bed.
5. In order for the laser to actually cut, the focus of the lens (the laser will be in the best state) needs to be located on the surface of the cutting material.
How To Choose Quality Metal Laser Cutter
The quality of metal laser cutting machine mainly depends on its cutting quality, which is a direct method to check the quality of equipment. For new buyers, they will first require proofing when purchasing equipment. In the process of proofing, customers not only pay attention to the cutting speed of the equipment, but also pay attention to the cutting quality of the sample. So how to judge the cutting quality? In addition, How to choose quality metal laser cutters? Following 3 methods will help us.
1. The surface will form a vertical line after using laser cutter . The depth of the texture determines the roughness of the cut surface. The lighter the texture, the smoother the cut section.
2. In generally, the cutting-width will not affect the cutting quality. However, when a particularly precise contour is formed inside a part, the cutting width has an important impact.
3. If the thickness of the metal plate exceeds 10mm, the perpendicularity of the cutting edge is very important. When leaving the focus, the laser beam will diverge. According to the position of the focus, the incision will widen towards the top or bottom.
