Whether you’re a seasoned pro or just dipping your toes in the engraving game, remember securing your glass is where it all begins. It’s like the foundation of every well engraving project.

– Focusing the Laser:

When it comes to glass engraving, focus becomes super important because it’s basically the difference between a refined, clear design and a blurry mess.

Luckily, ComMarker laser engraving machine has got this down to a science to make sure your engraving comes out top-notch every time. We’ve got manual focus systems in our laser systems that allow you to adjust the distance between the laser and the material surface, so you know it’s always spot on.

Also, before starting the actual engraving job, perform test engravings on scrap material to ensure that the focus is set correctly. This allows you to make any necessary adjustments before engraving the final piece, minimizing the risk of errors and ensuring a high-quality result.

 Engraving Settings for Glass

– Power and Speed Adjustments:

When engraving glass with a UV laser, know that UV laser operates at a shorter 355nm wavelength, and handling this laser radiation demands a perfect balance between power and speed.

Because too much power can risk heating up the glass too much, which could lead to cracks or even breakage. But if you go too light on the power, your engraving might end up looking faint or incomplete.

And then there’s speed – slower speeds give the laser beam more time to do its magic on the glass, which can result in deeper and clearer engravings. But go too slow, and you might end up burning the glass material with too much heat.

There’s always a rule to follow and that is —more power and less speed for dense and thicker glass such as tempered, borosilicate, crystal, and thick glasses because these materials typically require higher UV laser power for successful engraving due to their density and resistance to marking.

Fortunately, Our UV laser engraving machines offer precise control over power and speed settings, allowing engravers to tailor the engraving parameters to the specific characteristics of the glass being engraved. This ensures that the engraving process is not only efficient but also safe for the material.

– Frequency Settings:

Coming to the frequency settings, our UV laser machine allows for perfect adjustability to this parameter so you’re better able to control the amount of heat generated during the process. These adjustable frequency configurations are perfect to avoid the likelihood of thermal stress and subsequent cracking, especially when working with delicate or thin glass materials such as float, tabletop, or sheet glass.

However, a commonly recommended frequency range for glass engraving with a UV laser is typically between 20 kHz to 80 kHz. Know that this can vary depending on factors such as the type of glass, desired engraving depth, and the specific characteristics of the laser system being used.

Low to Medium Frequencies (20 kHz to 40 kHz):

  • These frequencies are suitable for engraving on thinner glass materials or when a shallow engraving depth is desired.

Medium to High Frequencies (40 kHz to 80 kHz):

  • These frequencies are ideal for engraving on thicker glass or when a deeper engraving depth is required.

 Enhancing the Engraving Process

– Using Wet Newspaper or Masking Tape:

Glass engraving can be a bit intimidating, demanding a higher level of care and control. If you wanna take it to the next level of precision and beauty, all you need to do is meticulously prepare the glass surface so that the engraving results can be pristine and free of all imperfections.

Grab some wet newspaper or masking tape and lay it on the glass before engraving. It’s a neat trick that helps keep things smooth and reduces the risk of chipping or cracking while the laser does its procedure. Basically, this simple trick absorbs some of the heat generated by the laser, providing a buffer between the glass and the intense heat of the laser beam.  

As a result, you end up with engravings that are cleaner and sharper, with way fewer imperfections. Plus, it’s a great way to minimize waste by repurposing materials you already have on hand, making your glass engraving process more eco-friendly.

–  Make Use of Safety Features:

While glass engravings have a more stunning aesthetic and beauty, the engraving process is quite a challenge. You know, combining laser beams and delicate substrates like glass, safety becomes a crucial element that takes all the lead.

That’s where our laser systems come in with their built-in safety features. With ventilation systems, machine enclosures, and protective shields on board, you can get your engraving on with peace of mind, meaning no worries about any mishaps.
