If your parts or components are manufactured with sheet metal, you’ve likely heard of laser cutting but may be unsure how it affects your designs. Laser cutting is a high-precision process that uses a focused, high-energy beam to cut different materials by melting, vaporizing, or burning. The laser is directed by CNC to follow a programmed cutting path, which allows for highly precise and complex cuts.
Sheet metal laser cutting primarily uses fiber lasers and CO₂ lasers. Though laser cutting works on many materials, it’s common for sheet metal fabrication of aluminum, carbon steel, stainless steel, and copper.
How Sheet Metal Laser Cutting Affects Component Designs
Laser cutting’s high accuracy makes for precise component designs and allows for complex geometries and intricate details. The level of accuracy laser cutting provides is crucial for industries that demand perfection in every part. Whether you’re working with delicate electronics or robust automotive components, laser cutting ensures that your designs are executed flawlessly.
Ideal for These Industries
A laser cutter’s narrow, high-energy beam allows for very precise, high-quality cutting, making it ideal for intricate part designs required for certain industries.
- Automotive – cutting sheet metal components
- Aerospace – fabricating precise aircraft parts
- Electronics – making components for devices
- Manufacturing – used for various products and components
Key Advantages
The unparalleled precision of laser cutting is one of the most significant benefits, but that’s just the beginning. This method offers many advantages that make it a superior choice for sheet metal fabrication.
- High Precision – can achieve very tight tolerances and cut widths as small as 0.1 mm depending on material type and thickness
- Versatility – able to cut a wide range of materials, including plastics, metals, and wood, depending on the laser type
- Speed – quickly cuts 2D profiles
- Automation – a highly automated process with minimal manual intervention, reducing human error
- Low Tooling Costs – no physical tools that wear out
Improved Accuracy With Sheet Metal Laser Cutting
While manufacturing precision can be unattainable with other fabrication methods, laser cutting makes it possible. It combines speed and accuracy, making it the go-to choice for projects where tight tolerances and intricate details are essential.
-
Precision and Accuracy
With accuracy levels of +/- 0.1 mm, laser cutting is ideal for high-precision applications. Compared to waterjet cutting and CNC machining, laser cutting boasts smaller kerf widths, which makes cutting fine geometries possible.
-
Versatility
Unlike plasma or EDM cutting, laser cutting works on conductive and non-conductive materials. It’s also capable of cutting and engraving a wide range of materials.
-
Speed and Efficiency
For thin materials, laser cutting offers faster processing than other fabrication methods, cutting at speeds over 3 meters per minute (depending on material type and thickness). Unlike CNC machining, there is no tool wear.
-
Edge Quality
Laser cutting produces clean, precise cuts and can produce clean edges, saving time and money on deburring processes.
-
Material Waste
The smaller kerf width allows for tighter nesting, making greater use of the material. By maximizing material usage, laser cutting minimized material waste, especially compared to traditional machining methods.
-
Limitations
Though there are many advantages to laser cutting, it does have its limitations. Compared to waterjet cutting, for example, laser cutting cannot cut very thick materials with the same level of precision because in certain materials heat can build up in a small area of the material.
Sheet Metal Laser Cutting at Miro Manufacturing
Laser cutting’s precision ensures that every component, regardless of complexity, meets the strictest standards of accuracy. This makes it a perfect fit for industries like automotive, aerospace, electronics, and general manufacturing that require tight tolerances.
At Miro, our lasers can cut aluminum up to ½” thick, stainless steel up to ¾”, and mild steel up to 1”. We have an 8000-watt fiber laser with full load and unload automation, ideal for high-volume projects. Though laser cutting is already a fast and efficient process, the cutting speed of our 8000-watt laser is exceptional, and it can produce a cut surface near a machined finish, potentially eliminating the need for secondary operations and reducing costs. To round out our laser cutting capabilities, we have a 4500-watt CO2 laser that’s ideal for carbon steel projects. By choosing Miro Manufacturing, you’re ensuring that your components are crafted with the highest level of precision, speed, and efficiency.
