Core components of laser cutter – Damon

In certain metal processing processes, laser cutting machines have gradually replaced traditional cutting methods. Because of  their unique advantages. And it have become more common usage in the cutting process. So, what are the core components of a laser cutting machine?

Fiber laser

Laser is the core “power source” in the core components of laser equipment. Like car engine, it is also a relatively expensive part of fiber laser cutting machine. So import from fiber laser brands on the market currently include German IPG, Rofin and British SPI. And with the development of science and technology, Chinese laser brands such as Raycus and Max continue to emerge. Thus they are  more and more popular in the market because of their high cost performance.

Core components – Cutting head

The cutting head is the laser output device of the fiber laser cutting machine. It consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine travels according to the set cutting track. But the height of the laser cutting head needs to adjust  if cut different materials, thicknesses and cutting methods.

CNC system

The control system is the main operating system of the fiber laser cutting machine. But it mainly controls the machine tool to realize the movement of X, Y, Z axis. And at the same time controls the output power of the laser. So its quality determines the stability of the working performance of the fiber laser cutting machine. Through the accurate control of the software, the cutting accuracy and cutting effect will effectively improve.


The performance of the motor directly affects the processing effect and production efficiency of the product. So at present, the commonly usage motors include stepper motors and servo motors. According to the type of industry and product type to processe, a suitable motor will configure.

Stepper motor:

Fast start-up speed and sensitive response, suitable for engraving and cutting processing with low requirements. There are many brands of stepper motors with different performances.

Servo motor:

Smooth cutting edge of processed products, fast cutting speed. High price is suitable for industries and products with high processing requirements.

Machine tool

Fiber laser cutting machines have high requirements for the stability of the machine tool. At present, the mainstream machine tools on the market include gantry type, cantilever type, beam type, etc. Different machine tools have different functions. For example, beam machine tools mainly use for material cutting in large manufacturing companies. And they can also be used for model cutting in specific fields such as 3D fiber laser cutting. It has a mainly usage in the automotive industry.

Laser lens

Many optical devices have laser lenses. Different lenses have different functions. Including full mirror, half mirror, focusing lens, etc. The quality of the lens directly affects the output power of the laser and the performance of the whole machine.
