Laser Cutting Vs. Laser Engraving Machines

Over time, laser cutters and laser engravers have become popular. The reason? The introduction of some government and industry regulations regarding part identification and legible product. These laser services add distinct solutions to products by providing permanent marking solutions.

What sets these services apart?

Although these techniques belong in the same category, they are distinct in a number of ways. The differences between each process are associated with the depth of the laser marking and the overall changes in appearances. Hence, the difference between both categories of lasers is the depth of penetration.

Fiber laser cutting machine

If you want high precision cuts at great speed, fiber optic laser cutters are the perfect choice. The 20 years old technology mostly gets its power source from a fiber laser. But all laser cutting machines differ in power of fiber source and focal distance of the laser beam. Also, these machines require an oxygen cylinder for function and operation while consuming so much energy at once. Fiber laser cutting machines cut metals as deep as 20mm. More details!

A variant of laser cutters

Another laser technology that cuts metals like laser cutters is the CO2 laser cutter machine. But this machine is designed to cut carbon steel, stainless steel, acrylic, copper, and wood. You won’t get clear and precise cutting effects with other materials. It also has a maximum power cut of 2mm. The significant difference between this laser cutter and its mother cutter is that the latter has a longer working life. While the fiber optic machine has 105 working hours, optical CO2 laser cutters have 2 x 104 hours of work.

Another important observation about this machine is that it is specially designed for metal cut only. Also, the machine is incapable of laser engraving because, during cutting, the head concentrates the fiber light beam at a single point.

Fiber laser engraving machine

Fiber-optic laser engraving machines enjoy similar perks as cutting machines. Some of the benefits include equal power source and technology. The only disparity, being lower power, explains its minimum power usage of 300W and a maximum power of about 150W. However, these machines have a power supply between 300W and 8000W. The power setups of fiber lasers – namely, 5W to 120W – are insufficient to cut metals at such high speeds as the fiber cutters. Furthermore, fiber engraving machines work with a profound effect, with a depth of engraving between 0.5 and 5mm, depending on:

  • The power of the engraving machine
  • Material used
  • The time during which the engraving repeats patterns

While fiber engravers use galvanometer heads that are responsible for high-speed engraving, fiber laser cutting machines use a different head that concentrates the high power of the fiber source for high-speed cutting. More so, the primary function of laser cutters is seen in materials such as bronze, brass, copper, stainless steel, fiberglass, some garments, and a few plastics.

Although fiber cutting machines cut at higher speeds than laser engravers, these machines can engrave over different materials at super high speed. Learn more details at:—Is-It-Right-for-You?&id=9458248
