Cnc laser cutting machine

Types of cnc laser cutting machine

A laser cutting machine employs the focused beam of a laser to cut materials like metals, plastics, and woods. With the help of CNC (Computer Numerical Control), users can get very fine and accurate cuts in just a short amount of time. Below are the laser cutting machine types.

Co2 laser cutting machine

A Co2 laser cutting machine generates its laser cutting beam through a mixture of gases, 20-30% of which is carbon dioxide. As a flash of electricity runs through the gas, it will then be used to cut materials. Co2 laser cutting machines are ideal for non-metal cutting, with most being able to cut 6-10mm of acrylic and wood, though it can also cut thin metallic sheets.

Because of the direction it has to be focused, a Co2 laser cutting machine cannot reach deep into the material, making it ideal for surface cutting only. However, a Co2 laser cutting machine's operation cost is very low and ideal for small businesses.

Fiber laser cutting machine

A fiber laser cutting machine works almost the same as a Co2 laser cutting machine; the only difference is that this machine uses a fiber optic cable to generate the laser beam by focusing and injecting it into the material's surface to make the cut.

Fiber laser cutting machines are more efficient than Co2 laser cutting machines because they use less electricity. They are more accurate and can make tighter cuts into thinner sheets of metals. A fiber laser cutting machine is mostly used to cut Co2 laser machine materials, especially stainless steel, aluminum, and copper.

Crystal laser cutting machine

A crystal laser cutting machine is so named because it uses solid-state laser rods made of crystals like YAG or Ytterbium as the source of the laser. A crystal laser cutting machine is mostly used in the industrial field to cut and engrave materials like gold, silver, and other precious metals.

Although a crystal laser cutting machine has tremendous power and can cut any material in high detail, its cost of acquisition is pretty steep, not to mention its running cost. A crystal laser cutting machine requires a high level of expertise to operate it.

Hybrid laser cutting machine

A hybrid laser cutting machine employs both fiber and Co2 technologies. This laser cutting machine sets itself apart by using a fiber laser for metals and a Co2 laser for acrylics and wood cutting. It can also automatically switch between the two if needed.

Hybrid laser cutting machines offer more versatility for businesses that cut a wide range of materials. For instance, if a metallic surface requires cutting, the device will automatically switch to the fiber laser to avoid any adhesion problem that is common with metallic surface and Co2 laser. In contrast, if a non-metallic surface is required to be cut, it will switch to Co2.
