Key Takeaways
- A BLM tube laser cuts holes, slots, miters, copes, and profiles in one automated process, replacing sawing, drilling, and punching.
- This consolidation replaces up to six fabrication steps and cuts labor by 60 to 80 percent in most applications.
- Fewer setups and less handling let Fraser Steel hold a typical tolerance of +/- 0.005 inches on laser-cut tube.
- Fraser Steel runs seven BLM tube lasers, the largest tube laser fleet of any contract manufacturer in North America.
- The lasers handle round, square, rectangular, oval, and custom tube from 1/2 inch to 6 inches in diameter, with walls up to 1/4 inch.
If you source tube parts, you know how many stops one part can make. It goes to the saw, then the drill press, then the punch, and every stop adds handling, waiting, and another chance for something to come out off. A BLM tube laser skips most of that. It cuts the holes, slots, and angled ends you need in one automated pass.
Fraser Steel runs seven of these machines in Albertville, Minnesota, and calls it the largest tube laser fleet of any contract manufacturer in North America. For you, that means parts that match your print and repeat from run to run, a shorter path from drawing to delivery, and fewer surprises that put your schedule at risk. Here is how it works and what it means for the tube parts you buy:
What a BLM tube laser does differently
Traditional tube preparation moves a part through sawing, drilling, punching, and deburring, with material handling between each stop. Every stop adds a setup, and every setup is a chance for error.
A BLM 3D tube laser loads the tube, positions it, and uses a multi-axis laser head to cut every feature in one continuous process. This replaces up to six fabrication steps and removes 60 to 80 percent of the labor required by conventional methods in most applications. The system also adjusts automatically between jobs, which keeps changeovers short on mixed production schedules.
The same machine produces the features OEM designs call for most often:
- Holes and slots at precise locations
- Miters and copes for tight tube-to-tube joints
- Profiles, edges, and complex end shapes
- Etching for part identification

Where tight tolerances come from
Tolerance stack-up is the cost of moving a part between machines. Each move re-references the part, and each re-reference adds variation. When a tube stays in one machine from the first cut to the last, the features are cut relative to each other, and hole-to-slot location no longer depends on how well the part was fixtured three times in a row.
That is how Fraser Steel holds a typical tolerance of +/- 0.005 inches on laser-cut tube, and why parts repeat from run to run. Cleaner cuts and consistent coped ends also mean better fit-up downstream, which matters when the next step is robotic welding or precision tube bending.
Typical tolerance on laser-cut tube: +/- 0.005 inches
Tolerances depend on material, wall thickness, and part geometry. Send your print and our engineers will confirm what is achievable for your part.
What the system can cut
Fraser Steel’s BLM lasers process a wide range of tube sizes, shapes, and materials:
- Diameter: 1/2 inch to 6 inches
- Wall thickness: up to 1/4 inch
- Materials: mild steel, stainless steel, and aluminum
- Shapes: round, square, rectangular, oval, and custom profiles

How a laser-cut tube part moves from print to production
A tube laser is only as good as the job that feeds it. At Fraser Steel, a typical part follows four steps:
- Design review: Engineers check tube geometry, wall thickness, and features against what the laser and downstream processes can hold.
- Setup: The system sets up automatically between jobs, so a new part number does not mean a long changeover.
- Cutting: The laser head cuts every hole, slot, miter, cope, and profile in one continuous process.
- Next operation: The finished tube moves to bending, welding, machining, or finishing in the same plant.
Keeping those steps under one roof removes the handoffs between vendors that a multi-supplier tube program requires.
Seven lasers, one plant, and scale OEMs can plan around
Fraser Steel has run BLM’s fastest tube lasers for more than 20 years. Today the 80,000 square foot Albertville facility houses seven of them among more than 30 major work centers, and about 200,000 parts leave production each day across more than 2,000 unique items in a normal year.
A deeper fleet gives planners more room to schedule high-volume production and prototype work side by side. Read more about how we put that capacity to work in What The Largest Fleet of Tube Lasers in the US Looks Like.
Engineering support before the first cut
A tube laser rewards good design, and Fraser Steel’s engineers review tube geometry, wall thickness, and features before production starts. Design for manufacturability reviews, SolidWorks support, and most standard OEM CAD formats are part of design and engineering, and rapid prototyping validates fit and function before a full launch.
Quality systems back it up. Fraser Steel is ISO 9001:2015 certified, uses FMEA to design out failure modes before production, and is ready for Tier 1 PPAP levels 1 through 5.
What this means for OEM sourcing
Every operation outsourced to a separate vendor adds freight, queue time, and a second quality system to manage. Because Fraser Steel cuts, bends, welds, machines, and finishes tube in one facility, an OEM can buy a finished component from one supplier instead of coordinating several.
The laser supports that model in practical ways:
- Lower labor content: One process replaces up to six steps, which reduces the touch time built into each part.
- Consistent parts: Fewer setups and less handling reduce variation between lots.
- Faster changes: Automatic setup between jobs helps when volumes or part numbers shift.
- Less waste: Fraser Steel cites minimal material waste as a benefit of the process.
Industries that rely on laser-cut tube
Laser-cut tube feeds frames, structures, and assemblies across many markets. Fraser Steel supports OEMs in automotive, medical equipment, agriculture, recreational vehicles, solar, exercise equipment, furniture, and more.
Typical parts include chassis and frame components that move from the laser to bending, welding, and finishing under one roof.
