Novanta Photonics, Laser Cutter Steel, and Best CO2 Laser Cutter: An Admin FAQ

I'm the administrative buyer for a 35-person custom fab and machining shop. I manage roughly $400k in annual procurement, from tooling to laser equipment. I'm not a laser engineer. I'm the person who reads spec sheets, asks uncomfortable questions, and writes the PO. In 2023, we brought laser cutting in-house. These are the questions I wish someone had answered before I signed the first quote.

Here's what this FAQ covers:

1. What is Novanta, and what does Novanta Photonics make?
2. Why does Novanta Bedford keep coming up in quotes?
3. Can a laser cutter actually cut steel?
4. What is a UV laser cutter, and should I consider it?
5. What is the best CO2 laser cutter for a small shop?
6. What should a non-engineer check before buying?

What is Novanta, and what does Novanta Photonics make?

Novanta is a photonics and precision motion control company. Novanta Photonics is the segment that designs and builds the laser sources, beam delivery components, and motion stages that go inside industrial cutting, marking, and welding systems. In many machines, you won't see Novanta on the front door. You'll see it inside the electrical cabinet and on the service labels. For me, that means the OEM trusted the component maker enough to put their name on the core of the machine.

When we compared laser systems, I kept seeing the same component-level brands across different machine builders. That consistency made me more comfortable choosing a specific system. It also made repair parts easier to source.

Why does Novanta Bedford keep coming up in quotes?

Novanta is headquartered in Bedford, Massachusetts. When a quote lists Novanta Bedford, that's the corporate headquarters and the legal address on the service documentation. For a buyer, a real address matters because it means there is a company behind the components. We learned this the hard way with an earlier support issue. Since then, I check that the critical components in any machine come from manufacturers with real addresses and serviceable infrastructure.

I went as far as asking our laser system supplier to confirm the source of the RF-excited CO2 tube. It turned out to be a Novanta Photonics product. That answer took ten minutes to verify and gave me something I could point to when finance asked why this machine cost more than a budget import.

Can a laser cutter actually cut steel?

Yes, but not every laser cutter can. A 40W desktop laser will not cut steel. It might mark it. If you're shopping for a laser cutter steel application, don't start with wattage. Start with material thickness and edge quality requirements. Cutting steel requires enough laser power, a suitable wavelength, and the right assist gas. In our experience, a CO2 laser can handle thin mild steel with oxygen assist, but a fiber laser is usually the better tool for thicker or reflective steel.

It's tempting to think that wattage is the only number that matters. That's an oversimplification. Beam quality, spot size, motion control, and cutting speed all matter. The spec sheet might say 100W, but the cutting chart tells the real story.

I'm not a laser engineer, so I can't tell you the exact kerf width for every alloy. As an admin buyer, I know to ask for the cutting chart by material and thickness. If a salesperson won't put 'mild steel, 3mm, oxygen assist, expected speed' in writing, that's a red flag.

What is a UV laser cutter, and should I consider it?

A UV laser cutter operates at a 355nm wavelength. In simple terms, it uses higher-energy photons to remove material by breaking molecular bonds rather than by heating it. This is often called 'cold ablation.' It's useful for plastics, thin films, ceramics, and some metals where you want a minimal heat-affected zone.

When we added a UV marking and cutting station, it wasn't for production steel. We use it for serial numbers and thin polycarbonate covers. The edge quality on those parts is better than what our CO2 laser could do without visible burn marks.

Because I came from print buying, I initially asked about DPI. In commercial print, 300 DPI is the standard baseline for quality. With a UV laser, DPI still matters for raster engraving, but for cutting, the more useful specs are pulse energy, focal spot, and repetition rate. DPI alone won't tell you if the machine can cut the part without melting it.

What is the best CO2 laser cutter for a small shop?

I don't believe there is a single 'best' CO2 laser cutter. There is a best laser for your job mix, your power capacity, and your maintenance appetite. For our shop, a 100W CO2 source mounted in a solid gantry frame was the right balance. It cut acrylic cleanly, engraved coated metals, and handled occasional thin steel with gas assist.

The lesson I learned is that the laser source matters more than the machine brand. We chose a system built around a Novanta Photonics CO2 source because the source has a documented service life. It cost more upfront, but the total cost per operating hour has been lower than some machines half the price.

People think a higher price means the machine must be good. Actually, a higher price can mean the builder spent more on components, cooling, and support--the things that keep a machine productive. The causation runs from engineering investment to price, not from price to quality.

What should a non-engineer check before signing off on a laser cutter?

Before you buy, check the duty cycle. This is the percentage of time the laser can operate at full rated power over a defined period. If you plan to run production, a 50% duty cycle will hurt. We almost missed this because the quote only listed peak power. We assumed '100W' meant it could run 100W all day. It couldn't. That was a costly assumption.

Also verify these material and service items:

• Cutting chart for the materials you actually process, not just the most impressive material.
• Assist gas requirements and whether your shop has the right connections.
• Chiller capacity and ambient temperature rating. A machine rated at 25C may not perform the same in an unairconditioned shop.
• Duty cycle at maximum thickness, not just at thin material.
• Spare parts availability and the manufacturer's service address.

Efficiency isn't just about speed. It's about not waking up to a half-finished job because the laser source shut down. We cut our typical turnaround from five days to two by bringing cutting in-house, but that only works because the equipment can sustain a real production schedule. The machine with a better duty cycle is the machine that makes you look better when operations reviews your numbers.

I also recommend checking the laser safety standard. We referenced ANSI Z136.1, Safe Use of Lasers, when we installed the enclosure and interlocks. I'm not a safety officer, but I made sure the installer showed us the compliance paperwork. That's a step I would not skip again.
