The Fiber Laser cutting machine is a particular machine for cutting or processing metal. It effectively solves all the drawbacks of traditional metal cutting.
It allows for safer and more efficient cutting of metals such as copper, aluminum, stainless steel, carbon steel, and iron.
Fiber laser cutting technology is widely used in many metal manufacturing industries.
In this article, I will list the best metal cutting machines on the market.

GH Series - High Power Laser Cutter Machine

With a maximum power of up to 12,000 W, this metal cutting machine is an excellent choice for cutting thick metal sheets.
The focusing mirror supports auto-focus with an accuracy of up to 0.01mm, making it an excellent choice for high-precision cutting widths.
The extra large format and heavy bed process can accommodate full plate metal cutting up to 12M.
However, this fiber laser cutting machine is more expensive, and if you need something cheaper, you can choose the 3015E series metal cutting machine.
I evaluated the machine's performance, size, and working area and found it to be an excellent choice for industrial sheet metal cutting.

The Fiber laser cutter has a machine size of 11475*2574*5169mm and a working area of 4000*2000mm.
The optional 8000W laser in the GH Series has a maximum marking speed of 200m/min. It can efficiently cut stainless steel, carbon steel, iron, and various alloys.
The laser cutter machine is also equipped with a Taiwan YYC rack and pinion, a Japanese Yaskawa motor, and a French speed reducer with a cutting acceleration of 2.5G.
The latest cutting-edge smoke control technology with strong negative pressure 360° adsorption improves purification efficiency and rejects lens contamination.
The laser cutting machine has four additional straps on the table to maximise the life of the machine table.
We are supported by a 3 year warranty and remote guidance from an engineer.

GAR Series - Plate and Pipe Fiber Laser Cutting Machine

This CNC fiber laser cutting machine is available in 1000W, 2000W, 3000W, 4000W, and 6000W and is one of the small to medium power types.
It uses lasers from well-known brands such as IPG and Raycus and has a long service life.
It is also available with a table size of 4000*2000mm and a choice of cutting sizes of 3000*1500 and 6000*2500mm. 0.02m repeatability allows for precision cutting.

Most efficient

The machine supports the joint cutting of plates and tubes for various uses and high production efficiency.
Motorised clamping design with a diagonal adjustment range of up to 20-300mm to protect the tube from deformation during extrusion.
Auto-focus and focus mirror with water-cooled heat sink increase the life of the laser head.
The bed is equipped with reinforcement bars to avoid bed deformation effectively.

LF3015GC metal cutting machine

The open-ended fiber laser cutting machine has outputs of 1000W, 2000W, 3000W, 4000W, 6000W, and 8000W.
The machine is equipped with a top and bottom exchange platform, which allows for fast exchange and saves time in loading and unloading. The cutting speed is also 120m/min, which is quick and efficient.
The bed frame is manufactured according to aerospace standards, is light in weight, and has a high load capacity. The thickness of the frame tube wall is 1CM, which provides a long service life.

What are fiber lasers?

Fiber lasers are the heart of the cutting machine, and the entire machine produces a highly focused laser beam, mainly using a fiber laser. You can easily cut hard materials with these laser beams. The short wavelength of the fiber lasers also provides a higher absorption rate during the cutting process.
What is a laser? This is a very abstract question. Here are the components of a laser.

• Gain medium
• Fibre optic
• Focusing mirror

The active medium is stimulated primarily using a laser and pumped through the fiber at the laser source. The laser beam is then transmitted from the fiber to a focusing mirror, which adjusts the laser beam and projects it onto the material.
Fiber lasers with different laser head sizes can produce unparalleled cutting speeds and cutting results. Compared to CO2 lasers, fiber lasers absorb laser light exceptionally quickly, making them suitable for cutting metallic materials. And with the smaller focal point size of the fiber, you can easily perform a wide range of precision cuts and engravings.

Prons of Fiber Laser Cutting Machines

• High cutting accuracy, ideal for cutting many precision metal parts
• High efficiency, you can produce more in less time
• Low downtime and little need for post-production maintenance. You only need to clean and lubricate the machine regularly
• Wide working range as it can cut almost any metal material
• Non-contact cutting, no wear and tear on the workpiece
• Flexible operation, direct computer control of the entire production process
• No need for punches and dies, saving production costs
• Smooth and aesthetically pleasing cutting surface. No manual handling required
• No deformation of the cut material and minimal laser influence on the cut area

Some potential cons of fiber laser cutting machines:

• The high cost of a metal cutting machines are relatively expensive
• The laser beam can be unimaginably dangerous to humans, and although the machine has various safety features, it should still be operated with care.
