Features Of A Metal Laser Cutter (Fiber Laser Cutter)

Engineers and machinery manufacturers prefer Fiber laser cutting technology over other thermal cutting methods. The reason is simple, the kind of flexibility, precision, and accuracy, laser cutting technology offers is tremendous.


Fiber lasers are intense lasers widely used in the metal cutting sector. According to Next Move Strategy Consulting, the worldwide fiber laser industry is expected to exceed treble between 2019 and 2030. The market is anticipated to grow to roughly 5.79 billion US dollars in 2030.


Until technological improvements allow for more advanced metal laser cutting, Fiber lasers will continue to dominate the industry for some time.


Let’s look at the features of Fiber laser cutters and why it’s preferred by manufacturers worldwide.


Features Of Fiber Laser Cutter

The fiber laser cutting machine comprises several sections. Moreover, it has different internal components. The metal laser cutting machine configurations yield different processing results. The essential elements of a fiber laser cutting machine are listed below. So let’s go through them one by one.


1. Fiber laser source

It is the main component of a fiber laser cutting machine. Furthermore, it serves as the power source for the fiber laser cutting machine, allowing it to perform precise cutting operations.

Fiber lasers use an optical fiber cable constructed of silica glass to guide the light(beam). They are energy efficient, require little maintenance, and have low running expenses.


2. Lenses

Laser lenses are the most commonly used component of fibre laser cutting equipment. A variety of optical devices use laser lenses. Some examples are semi-reverse lenses, full-reflex lenses,and focusing lenses. All these lenses serve distinct purposes.

The quality of the lens has a direct influence on the amount of power that is output by the laser, which in turn has an effect on the machine’s overall performance..


3. Laser Cutting Head

A fibre laser cutting machine’s cutting head is a laser output device. It consists of three parts:

  • a focusing lens
  • a nozzle
  • a focus tracking system


The laser cutting machine’s cutting head moves according to the selected cutting track. The height of the laser cutting head must be modified and controlled for varied materials, thicknesses, and cutting parameters.


4. Motors

Fiber laser cutting machines widely use two types of motors: the Stepper and servo motors. The Fiber laser company and product type determine the engine’s configuration.


The motors in The fibre laser cutting machine are in charge of driving the control object with high accuracy and torque speed. The motors in fiber laser machine work like an engine, it operates the mechanical components of a motor system. It is an indirect speed-changing mechanism for auxiliary motors.


  • The stepper motor

It offers a quick start-up time and a delicate response, making it ideal for engraving and cutting applications.

They are cheap, not expensive. Stepper motors come in a variety of manufacturers and performance levels.


  • The servo motor

The motor has Smooth edge processing and fast cutting speed; high pricing, appropriate for industries and products with high processing requirements.


5. Water Chiller

An essential component of most laser machines is the water chiller, whose job it is to lower the water temperature. Most chillers facilitate heat transfer from water by means of a closed-loop system utilising refrigerant. The hot, unwanted heat is then expelled into the air via a pipe carrying the refrigerant.


For optimal beam quality, medical and research lasers require precise temperature control. Opti Temp liquid cooling devices (chillers) remove heat from commercially accessible lasers. This aims to prevent essential components in industrial and medical lasers from overheating.


6. Air Cutting System

The air-cutting system of a fiber laser cutting machine consists primarily of an air compressor, a filter device, and an air drier. Two types of air sources are mostly available: bottled air and compressed air. Air cutting is more environmentally friendly than other gas-cutting methods; the reason for using air cutting is to save money on gas use compared to Nitrogen.


7. Host Workbench

The fibre laser cutting machine’s bed, beam, worktable, and Z-axis system serve as the host. When operating the fibre laser cutting machine, the operator must first position the workpiece on the bed before using the servo motor to drive the beam and regulate the Z-axis movement. The operator can change the parameters to match their specific needs.


8. Rack

Machine stability is essential in fibre laser cutting equipment. Currently, the most common racks on the market are gantry type, cantilever type, beam type, and so on, and each frame serves a distinct purpose.

For example, large industries use Beam racks mainly for material cutting. Models for specific fields, such as three-dimensional fibre laser cutting, are also available and are primarily employed in the automotive industry.


9. Control System

Like any other machine, the Fiber laser cutter’s control system regulates machine functioning. It primarily controls the machine tool, allowing it to move along the X, Y, and Z axes. Moreover, it holds the laser’s output power. Its quality affects the fiber laser cutting machine’s operating performance stability. Software control can increase the cutting effect.


10. Voltage Stabiliser

The voltage needs for some high-precision equipment with high voltage requirements are incredibly high. If the voltage is unstable, manufacturing will suffer. The same applies to a fibre laser machine: A fibre laser machine has a specific automatic voltage regulator between the laser machine, the CNC machine tool, and the power supply system.

A voltage stabiliser can transform an abnormally high or excessively high voltage into the laser machine’s normal working voltage range. So the laser equipment can continue functioning correctly.


11. Ventilation Dust Collector

The ventilation dust collector in the fiber laser machine is in charge of extracting the smoke and dust. Fiber lasers produce dust during production, which can be harmful. Dust controller filters the exhaust gas output to ensure it meets environmental protection regulations.


Fiber lasers are well known for their fast processing times, high reliability, and high performance. It requires little maintenance and can process highly reflective materials such as copper and brass.  The benefits of using a Fiber laser cutting machine are significantly more potent than those of other laser machines, and this is because of the machine’s exceptional components.
