Fiber laser vs. CO2 laser
Why fiber laser in more efficient than CO2 laser
In laser cutting services Toronto, the laser cutting system that is used depends on the type of material that will be cut. For metals, ceramics and semi-conductor materials like silicon, fiber laser beams are used for very fine laser cutting with kerf widths of less than 20µm at cutting speeds of 10m/min. Due to the possibility of modulating fiber laser beam at high frequency for faster response times, even small features are possible with very high accuracy and repeatability.
Fiber laser light is created through banks of diodes that is channeled and amplified through a fiber optic cable similar to what is used in data transfer. This is amplified when exiting the fiber cable and straightened and then focused by a lens on the material that will be cut. Laser cutting services Toronto frequently makes use of fiber laser because the creation of light is 200% more efficient than CO2 lasers and delivery is simpler because it does not use expensive optical mirrors. Another advantage is the reduction on maintenance requirements and operating costs.
Why more OEMs and subcontractors prefer CO2 lasers
Laser cutting services Toronto frequently make use of CO2 laser cutting because it is faster in a straight line with faster piercing time at the start of the cut. When cutting thicker materials, CO2 laser cutting provides a smoother surface finish. Many OEMs and subcontractors are more confident in buying CO2 lasers because it is more versatile for job orders that tend to differ in the thickness of its materials. The main reason for purchasing fiber laser cutting machines is the speed of cutting thin materials in the range of 1mm to 2mm or up to 3mm. Another reason is lower energy consumption and lower running cost.
Laser cutting vs. water jet cutting
Another technology used in cutting materials is water jet cutting that makes use of pressurized water mixed with abrasives. Water jets can virtually cut through any kind of material that ranges in thickness between 0.4” to 2.0” but it is not as precise a laser cutting. In laser cutting, precision is not an issue since the minimum size of the cutting slit is 0.006” based on the speed of the laser. The overall risks in using lasers are very minimal compared to water jet cutting that must be handled carefully. Laser cutting is also more economical and efficient because of minimal waste and cleanup. Water jet cutting process is not only noisy; it requires a significant amount of cleanup because of the large amount of water and abrasives used.
