Considerations when buying a fiber laser

Cylion Product Page

When looking to invest in a fiber laser, there are several important factors to consider before making your purchase.

1. Maintenance and Operating Ease

One of the major advantages of fiber lasers is their low maintenance requirements. Unlike traditional lasers, fiber lasers do not have mirrors that need alignment or cleaning. However, you will still need to change the nozzles depending on the material being cut, and these nozzles will need periodic replacement. Additionally, the protective lens should be changed regularly to ensure optimal performance. Overall, you will find fiber lasers to be easier to maintain compared to older models.

2. Training and Setup

Fiber lasers come with a steep learning curve. It is highly recommended to hire a technician for proper installation and training. While it is an additional cost, it is often included in the overall price of the machine. Ensure you provide accommodations and meals for the technician during their visit to assist you.

3. Component Longevity

The lifespan of a fiber laser source is impressive, with about 100,000 hours of use expected. This far exceeds the lifespan of a CO2 tube. Solid-state devices, used in fiber lasers, are designed to have a longer operational life, minimizing deterioration over time.

4. Safety Considerations

Using an un-enclosed fiber laser machine poses a higher risk of exposure, particularly in workplaces with employees. In many countries, having an open machine is not permissible for safety reasons. While it is feasible to operate an open machine if you take the necessary safety precautions—for instance, wearing protective eyewear—a fully enclosed model might be the safer option for industrial environments. Enclosed machines often come at a higher price but include features such as exchange tables for ease of use.

5. Dust Management and Ventilation

Cutting metal produces a significant amount of dust that must be adequately extracted to maintain safety standards. Stainless steel cutting can create hexavalent chromium dust, while galvanized steel releases toxic fumes. Therefore, ensuring proper ventilation and extraction systems are in place is crucial.

6. Investment and Sourcing

A budget under $40,000 may limit your options significantly. My experience with a 1 kW machine, including shipping and duties, highlighted the importance of buying from reputable manufacturers rather than trading companies. When investing in a fiber laser, prioritize quality and reliability over cheap pricing.

Addressing Common Questions About Fiber Laser Cutting Machines

As fiber laser cutting machines gain popularity, prospective customers frequently have inquiries. Here, we address some of these common concerns:

Why Is There a 0.2mm to 0.5mm Accuracy Difference in China’s Fiber Laser Machines After Extended Use?

First, it's essential that the machine table undergoes annealing treatment to relieve internal stresses before rough machining, followed by vibratory stress relief prior to fine finishing. If these processes are improperly executed or overlooked, machines will likely experience long-term accuracy issues.

The Standard Machining Process for Fiber Laser Machines

The standard process involves several stages: welding and annealing treatment to remove inner stress, followed by rough machining, vibratory stress relief, and more precise machining in subsequent steps.

Many manufacturers know about these procedures but either fail to implement them correctly or are unwilling to invest in these less visible aspects of production.

Second Common Issue: Use of Copy Parts

Some manufacturers opt for cheaper copy parts like gear racks and guide rails to compete on price. The cost of these copies can be significantly lower, potentially just 20% to 33% of the original components. While buyers may not notice the difference initially, problems often arise later during machine operation, leading to unsatisfactory performance.

Compromising on Machine Table Materials

Most factories in China utilize a similar design for their machines. While the welding tube frame serves as the base, the thickness can vary from factory to factory—from 12mm to as low as 8mm. Unknown to the buyer, some manufacturers will use lightweight or less robust materials, making it hard for the user to discern the actual quality received.
