Pulsed Fiber Engraving Machines

For those of you who know what Pulsed Fiber Engraving Machines are and want to mark or engrave metal parts, we have some cool technologies to share with you. For those who have no clue, you may find these technologies very interesting, read on to see what these technologies can do for your work, or see how your metal parts are made to gain a better appreciation of this highly specialized work.

A fiber laser machine is a tool that is used for marking metal parts as well as some types of plastics. Many industries make use of these machines for etching and surface without actually touching it for; high definition logos, data matrix codes, or serial numbers can be made on products and components, with a high-resolution finish. The technology entails the utilization of a laser beam that uses an optical fiber as its active gain medium. The fiber is treated with a unique earth element such as neodymium, erbium, dysprosium, or ytterbium. 

Fiber laser machines have numerous advantages over the conventional, solid-state lasers. One of the benefits is that fiber laser is way more stable because the laser beam is produced within the fiber. Also, the machine provides excellent control in regards to heat output, length, and beam intensity when marking even for novice users. Therefore, it creates legible, accurate, clean, and quick markings with ease. Additionally, they are low-maintenance machines, they can reach incredibly high amplification levels, which make them efficient, cost-effective, and sturdy, and they are great for precision etching. 

If you want to buy a laser machine, you have to choose the best fiber laser etching available in the market. LMT Pulsed fiber machines are some of the best laser machines in the market. Here are the ways in which they can be used;

Engraving

A machine that uses laser energy to engrave on metallic machines cause a mark on metals such as stainless steel. Ablation occurs in the area where laser marking has been done on stainless steel metal. When the fiber laser etching takes place, the material evaporates. Since laser has exceptionally high energy, materials such as titanium and steel can be made to evaporate directly.

Polishing

Since the introduction of DMLS (Direct Metal Laser Sintering) and 3D additive manufacturing, the pressure to lower the stress of post-processing 3D DMLS by polishing metals has been mounting. The SPI driven MOPA lasers manufactured by LMT have been specially used on many 3D metal systems to polish Ti6A14V using a laser. They can provide as many as ten times lessening of cylindrical surfaces and as many as 21.5 times decreasing of surface roughness for flat surfaces. The scanning pattern which used to be known as the Moiré pattern in the printing industry duplicates halftone printing angles and functioned best because of the use of certain angles (0°, 18°, 72°, 45°).

Annealing 

Annealing machines do not leave ablation on the surface, and neither does it remove the material on metals such as stainless steel. However, the laser annealing machine will make a dark contrast mark that will pass passivization cycles if it is used well. No material is removed; hence, there is no ablation. Making use of a laser annealing machine with various metals, including stainless steel alloys results in a marking that is corrosion resistant. By using annealing, the surface of the structure is not subjected to any damage, and the mark made is permanent. Using the Master Oscillator Power Amplifier (MOPA), you can achieve different colors by taking advantage of the features available on the laser annealing machine, such as the pulse width modulation feature. Laser annealing can also be done on an alloy that comprises of iron. To learn more about similar devices, check out johnsonscale.com.
