CNC Engraving Stainless Steel: Gantry VS Galvo 30W Fiber

CNC engraving stainless steel can be done in a variety of ways by CNCROi.com, today, we’ll review how we do it using a gantry and galvo style 30 watt fiber laser source.

Jon from CNCROi.com is demonstrating CNC engraving on stainless steel using an overhead gantry system and a galvo fiber laser. The process involves fiber laser etching on 12-gauge stainless steel, approximately 2.6mm thick. The comparison between the overhead gantry system and the galvo system highlights the differences in engraving speed, efficiency, and application.

When it comes to CNC engraving stainless steel, power ratings are crucial. Whether using a 30W, 50W, or 100W fiber laser, the power output remains consistent regardless of the system. While the galvo laser can be faster in some applications, the overhead gantry system is more efficient for larger surface areas

The overhead gantry system, such as the Trotec Speedy 400 Flexx, moves back and forth to engrave the material. In contrast, the galvo fiber laser uses a mirror system to achieve faster etching speeds. However, speed alone does not determine efficiency, as different applications require different engraving methods.

CNC engraving stainless steel with a fiber laser ensures precision and durability. The Trotec Speedy 400 Flexx features both CO2 and fiber laser tubes, making it versatile for various materials. However, software differences impact engraving settings and processing times between the two systems.

Furthermore, etching can be converted to annealing based on the focus of the beam, though etching is far more desirable by CNCROi.com.

The overhead gantry system’s primary limitation is its movement pattern. It must travel left to right or up and down, whereas the galvo system can move dynamically across the material. This flexibility gives the galvo laser an edge in certain applications.

Despite their differences, both systems produce the same final engraving result. The choice between them depends on the application requirements, material size, and production volume. CNC engraving stainless steel efficiently requires selecting the right system for the task.

The galvo fiber laser is optimal for engraving small parts under four inches. It offers faster processing times, making it ideal for high-volume production. However, when dealing with large stainless steel sheets, the overhead gantry system is more practical.

Fiber lasers can be matched with other processes, such as waterjet, plasma and even manual processing tools which CNCROi.com has.

Large-scale CNC engraving stainless steel projects benefit from the overhead gantry system due to its ability to process multiple pieces simultaneously. This efficiency reduces handling time and increases production output.

Fiber laser etching power typically ranges between 30W and 100W, while fiber laser cutting starts at around 800W to 1kW. Cutting power scales exponentially, with a 2kW laser cutting approximately 1.5 times faster than a 1kW laser.

No single machine is perfect for all applications. A diverse set of machines in a CNC shop provides flexibility and synergy for various projects. Choosing between a galvo or gantry system depends on the project specifications.

 Deep etching is possible using our gantry system, it isn’t a process dedicated only to the galvo, but the galvo is a better, more efficient method of deep etching.

For single stainless steel engravings, the galvo fiber laser is ideal for most applications that CNCROi.com handles. However, for bulk orders, the overhead gantry system is more efficient since multiple pieces can be engraved simultaneously.

CNC engraving stainless steel with the galvo laser allows for greater control over etching direction, prioritization, and detailing. This flexibility enhances the precision and aesthetic quality of engraved graphics.

Unlike traditional engraving methods, fiber laser etching does not require physical contact with the stainless steel surface. This prevents wear and tear, reducing inconsistencies and maintaining high-quality results.

Fiber laser etching stainless steel produces a range of color variations, from dark brown to black, depending on the heat intensity and oxidation effects. However, the color range remains limited compared to other marking methods.

Anything that is stainless steel can be etched, even pots and pans by CNCROi.com!

CNC engraving stainless steel is widely used in industries requiring durable markings, such as aerospace, medical devices, and industrial equipment. The permanence of fiber laser etching ensures longevity.

Stainless steel engravings remain intact even under extreme conditions. The markings do not fade, peel, or degrade over time, making fiber laser etching ideal for harsh environments.

For applications such as welding, CNC engraving stainless steel is beneficial. Fiber laser-etched markings by CNCROi.com can withstand high temperatures without distortion or fading.

Other metals can be engraved as well, including aluminium, though the results aren’t as spectacular on the raw form.

Removing fiber laser etchings from stainless steel is challenging. The only effective method is grinding, which often damages the material. As a result, fiber laser engraving is a permanent marking solution.

CNC engraving stainless steel is a precise and reliable process. Whether for industrial identification plates, custom signage, or serial numbers, fiber laser etching provides unmatched durability.
