  With the emergence of new tools, the technology involved in engraving techniques has really advanced. The most prevalent techniques in use today are laser engraving and micromachining. Here's an analysis of modern laser engraving and micromachining of substrates. What Is Laser Engraving & Micromachining? Laser engraving and micromachining are specialized techniques used to mark and create all kinds of images on diverse objects and surfaces. Technically speaking, both methods are known as surface or laser micromachining. They are now being used in all types of productions. Major Services Involved In Laser Micromachining In recent times, laser micromachining is used in making all kinds of services available, especially in the technological and industrial sectors. The services that could be rendered through the process include laser precision cutting, laser precision welding, laser marking and engraving, laser polishing and hardening, etc. It all depends on the distinct service ...

  High speeds and high versatility are the main benefits of laser micromachining when it comes to drilling and making holes. Micro-drilling has two distinct laser processes as with cutting: fusion drilling with pulsed lasers and additional gas support - and vaporization-induced melt ejection, such as with q-switched solid-state lasers. By choosing the proper wavelength and power density of the laser beam, almost all solid materials such as metals, semiconductors, plastics, ceramics, diamonds, etc. can be laser-drilled. Various Methods for Laser Drilling For selective roughening of surfaces for gluing and coating processes, pulse drilling of holes at a depth of some microns is used. Single-pulse methods may be used for through holes in small workpiece thicknesses. For thicker materials, percussion drilling is the first option and can be accomplished by applying several laser pulses with the appropriate depth. A combined drilling-cutting method or the multi-pass method is used for t...

Laser marking and laser engraving innovations in the pattern or mold making industry are becoming ever more prevalent. Mold makers know that machining small cavities in molds are difficult and time-consuming, and extensive hand polishing is usually required to finish the job. If the mold is either hardened or constructed of pre-hardened materials, the job is rendered much more difficult. Deep laser engraving provides an effective form of machining without contact that is effective on hardened tool steels and can penetrate hard-to-reach areas. Deep Laser Engraving Deep laser engraving is generally regarded as a machining process that removes up to 30 thousandths of an inch of material. It is often used for adding details to molds such as patterns and shapes, or for adding identification marks. Advantages of Laser Engraving A significant advantage of using picosecond and femtosecond lasers to engrave molds is that they operate well on hardened steel surfaces. It also works where...
