During your manufacturing, how to choose the right sheet metal laser cutting machine is essential to keep your cutting at high precision, efficiency and cost-effectiveness. Facing with numerous options available in the market, you also need to know what to look for. Here are 10 key factors to keep in mind when selecting a sheet metal laser cutting machine:
The power of a laser cutting machine is a critical factor to consider. Measured in watts, laser power determines both material thickness and cutting speed. The higher power can cut through the thicker materials at a faster speed, but they also tend to come with a higher price tag. For example, 1kW may be suitable for cutting the thinner sheet, while a 6kW or the higher laser (such as, 10kW, 20kW, 60kW) would be necessary for thicker materials up to 100mm.
Cutting speed directly impacts productivity. A faster cutting speed allows for more parts to be produced in a given time. Even so, the optimal speed is usually decided by material type and its thickness. Manufacturers often provide cutting speed charts to assist in selecting the right machine based on specific needs.
SENFENG’s Comparison Table of Different Laser Powers Between Sheet Thickness and Cutting Speed
Laser power | Max thickness of sheet | Max cutting speed |
1.5kW | 12mm | 23-30m/min (1mm thick sheet) |
3kW | 16mm | 30-45m/min (1mm thick sheet) |
6kW | 20mm | 45-55m/min (1mm thick sheet) |
12kW | 40mm | 15-18m/min (6mm thick sheet) |
20kW | 60mm | 23-25m/min (6mm thick sheet) |
30kW | 80mm | 23-30m/min (6mm thick sheet) |
60kW | 100mm | 26-30m/min (8mm thick sheet) |
As for industries needing intricate design and tight tolerance, cutting precision and accuracy are in the first place. Cutting precision may be affected by the quality of laser beam and the stability of the machine. Given this, you need to seek for machines with high repeatability and accuracy within the range of ±0.03 mm.
At present, there are including CO2, fiber and diode laser source. Each has its advantages and applications:
CO2 Lasers: Fit to cut non-metal materials and other thicker metals.
Fiber Lasers: Ideal for cutting thin to medium thickness metals thanks to its higher efficiency and cutting speed.
Diode Lasers: Compared with cutting, it is more suitable for engraving and marking.
Choose the laser source that best fits your material and cutting requirements.
Modern laser cutting machines work with various automated and control software. Through the minimization of manual work and setup time, automation helps to enhance your productivity. For that reason, it is necessary to look for automated loading and unloading devices, material handling system and advanced nesting software that optimizes material usage and reduces waste.
For customers, the early buying costs are just part of the all-in expenses. At work, they must think about the total cost of ownership made up of maintenance, consumables, electric charges and potential downtime. Fiber lasers, compared with CO2 laser generator, tend to require lower operating costs because of their higher energy efficiency and lower maintenance demands.
Before purchasing, you must ensure that your preferred machine is compatible with your material type. Different lasers fit for different materials. In comparison with CO2 lasers cutting wood, acrylic, plastics and other non-metals, fiber lasers are better for cutting metals like carbon steel, mild steel, aluminum and copper.
To minimize downtime and keep work smooth, the reliable technical support and service are crucial. So, all customers must carefully choose a manufacturer or supplier with excellent customer service, comprehensive training, and prompt technical support. Pay close attention to warranty period available and the ease of getting replacement parts.
Consider the space available for your new machine in your workshop. Laser cutting machines vary from overall dimensions and footprint, therefore you must ensure there is enough room for installation, operation and maintenance. However, some machines call for special installation conditions, incl. good ventilation and stable foundations.
When choosing a laser cutting machine, it is crucial to ensure compliance with local environmental regulations and safety standards. Look for machines that are equipped with proper exhaust systems to effectively handle fumes and dust. Additionally, verify that safety features such as protective enclosures and interlocks are in place, especially when working with materials that emit hazardous fumes.
Choosing the most suitable sheet metal laser cutting machine requires a thorough evaluation of several factors, including laser power, cutting speed, precision, and material compatibility. By carefully considering these ten essential factors, you can confidently make a decision to improve your manufacturing ability, boost productivity and lower overall costs. In order to work efficiently for a long time, we suggest you invest in a high-quality and trustworthy laser cutting machine customized based on your actual demands. Besides standard machines,SENFENG may also tailor to all customers in terms of laser power, working area and specific configuration, so as to further upgrade metalworking in all walks of life.
