Introduction

Just as the name suggests, the metal laser cutting machine is a type of CNC metal cutting machine adopting laser technology. There are currently two kinds of mainstream CNC metal cutting machines using laser technology in the market, i.e. CO2 laser cutting machine and fiber laser cutting machine. CO2 laser cutter is a type of CNC laser machine using CO2 laser to cut materials.

However, the CO2 laser machine has low efficiency in cutting metal materials. However, the fiber laser cutting machine is widely used for cutting metal materials because of its high cutting efficiency, good processing quality and low maintenance cost. Therefore, the metal laser cutting machine referred to in this article mainly refers to the fiber laser cutting machine.

CO2 laser cutter is a type of CNC laser machine using CO2 laser to cut materials.However, the CO2 laser machine has low efficiency in cutting metal materials. So it is generally  used to cut non-metal materials.

However, the fiber laser cutting machine is widely used for cutting metal materials because of its high cutting efficiency, good processing quality and low maintenance cost. Therefore, the metal laser cutting machine referred to in this article mainly refers to the fiber laser cutting machine.

Higher efficiency, less energy consumption and less operation cost

Electrical to optical conversion efficiency of the fiber metal laser cutting machine is high and over 30%. This greatly reduces the power consumption, saves operation cost, and achieves the higher efficiency. Equipped with a reliable and high quality laser generator, a laser cutting head and a sturdy machine structure, the fiber metal laser cutting machine can achieve a fast and steady cutting process. In addition, the fiber cutter machine reaches its highest efficiency when cutting thinner metal sheets. Its cutting speed can be twice the CO2 laser cutting machine with the same power. Therefore, it does not require frequent replacement of consumables, greatly saving operating costs and maintenance costs.

Non-contact process, high precision and small cutting slit

Due to the replacement of traditional cutting tools by a laser beam, the fiber laser cutting is a non-contract cutting process. So it will not scratch the material surface. The machining accuracy is high; the repeatability is good, causing no damage to the material surface.

Good quality, wide application and high automation

The output wave length of the fiber laser is 1.064μm, 1/10 of the wave length of the CO2 laser cutter. The laser beam has good quality and high power and density, and can be absorbed easily by metal materials. So the metal laser cutting machine has excellent cutting ability and the finished products are in good quality. With the assistance of matching CAD and other CNC programs, the metal cutting machine can cut any regular and irregular patterns. Except for sheet metal, it can also cut square or round metal tubes. The metal laser cutting machine is capable for cutting a wide range of metal materials, even though highly reflective metals. With high level of automation, the operator only needs to make the desired design on the computer and fix the material on the worktable. The cutter will automatically complete the cutting work without human intervention.

Advantages of laser cutting over traditional mechanical cutting

Faster speed and higher cutting quality;

Reduced workpiece contamination and damages, due to non-contact cutting process of the laser cutting;

Higher cutting precision, because the laser beam will not cause any wear during the cutting process;

Smaller heat affected area and part deformation.
