Fiber Optic Laser Cutting – ComMarker B4 Fiber Laser Cutting

Fiber Laser Cutting

Laser cutting has revolutionized many industries with its precision and accuracy. One of the latest advancements in this field is the Fiber Laser Cutting Machine. We will delve into the intricacies of fiber laser technology, exploring its operation, advantages, applications, the types of materials it can cut, and the cutting depths it can achieve.

What is Fiber Laser Cutting?

Fiber laser cutting is a highly efficient laser cutting technique that utilizes a high-power laser beam focused through a fiber optic cable. This cable is composed of flexible glass fibers that guide the laser beam to the cutting head. The precision and small spot size of the laser enable intricate shapes and high-accuracy cuts, making it an essential tool in various industries.

How Does Fiber Laser Cutting Technology Work?

Fiber laser cutting technology operates through a series of well-coordinated steps:

  1. Laser Beam Generation: The process begins with a laser diode that generates the initial laser beam. This beam is then amplified within the fiber optic cable, which is doped with rare-earth elements such as ytterbium.
  2. Beam Focusing: The amplified laser beam is focused through a lens, creating a highly concentrated energy spot.
  3. Material Interaction: When the focused laser beam contacts the material, it melts, burns, or vaporizes it. An assist gas, like nitrogen or oxygen, blows away the molten or vaporized material, resulting in a precise cut.
  4. Motion Control: Advanced software and computer numerical control (CNC) systems guide the cutting head along the desired path, enabling the machine to cut complex shapes with high accuracy.

What Metals Can Be Cut With Fiber Laser Cutting Machines?

Fiber laser cutting machines are versatile and can cut a variety of metals, including:

  • Stainless Steel: Ideal for applications requiring corrosion resistance and strength, such as in the medical, food processing, and automotive industries.
  • Carbon Steel: Commonly used in construction and manufacturing due to its strength and durability.
  • Aluminum: Widely used in aerospace and automotive industries due to its lightweight and high reflectivity properties.
  • Brass and Copper: Fiber lasers efficiently cut these conductive and reflective metals, making them suitable for electrical components and decorative items.
  • Titanium: Essential in aerospace, medical, and military applications for its strength and corrosion resistance.
  • Nickel Alloys: Used in high-temperature and corrosive environments, these alloys are cut effectively by fiber lasers.

How Deep Can a Fiber Laser Cut?

The cutting depth of a fiber laser depends on several factors:

  • Laser Power: Higher power lasers can cut through thicker materials. For example, a 1 kW laser can cut through stainless steel up to 4-5 mm thick, while a 3 kW laser can handle thicknesses up to 12-15 mm.
  • Material Type: Different materials have varying thermal conductivities and reflectivities, affecting the cutting depth. Metals like aluminum and copper require more power due to their reflectivity.
  • Assist Gas: The type of assist gas can influence the cutting process. Oxygen, for instance, can increase cutting speed and depth for carbon steel due to the exothermic reaction it causes.
  • Cutting Speed and Focus Quality: Proper focus and a high-quality optical system result in a smaller spot size, higher energy density, and deeper cuts. The cutting speed also plays a role; slower speeds allow for deeper cuts.

Generally, fiber lasers can cut metals up to several centimeters thick, but the exact depth varies based on the material and cutting conditions.
