CI FiberMax fiber laser with up to 12 kW power, 3048×1524 mm bed, 2.2 G acceleration, built for nonstop sheet cutting.
Small sentences punch harder. 125 years on the market, that is how long Cincinnati Incorporated has been machining, bending, punching metal in Ohio. 5 generations of engineers tinkered with this FiberMax line, it shows. Now, onto the FiberMax itself, I keep calling it a grey beast, because it is, well, big, around 10 meters nose to tail.
The table is the familiar 3048 × 1524 mm. Why familiar, because every second fab shop in Dubai orders sheets in that cut-to-length. Push a 1.5 × 3 m SS plate on Monday, throw in aluminium on Tuesday, the clamps do not care.
Right after the first list, let me derail a bit. People keep asking if fiber even makes sense for thick plate. It does, as long as you have enough kW behind the nozzle. Cincinnati offers from 2 up to 12 kW IPG sources. Most UAE shops land on 6 kW, strikes a balance between capex and nitrogen consumption.
Before more waffle, numbers on one screen help the brain park info.
| Item | FiberMax 6 kW | Middle-tier CO₂ 6 kW | Notes |
|---|---|---|---|
| Top speed | 170 m/min | 120 m/min | linear motors vs racks |
| Acceleration | 2.2 G | 1 G | jump hole to hole faster |
| Mild steel 25 mm | Clean edge | Needs slow feed | nitrogen cut on fiber |
| Power draw | 32 kVA | 45 kVA | diode wall-plug efficiency |
| Mirror maintenance | n⁄a | weekly wipe | obvious |
That little table explains why some managers ditch their aging CO₂ beds even before the lease ends. Less downtime, more parts per shift, lower electricity in a region where the grid can get moody mid-summer.
The gantry rides on linear motors, not ballscrews. Fat magnets, skinny air gap, crazy thrust. Cincinnati quotes 2.2 G, I saw 1.9 G on the oscilloscope during a square-wave jog, close enough. Repeatability sits at ±0.03 mm. That means parts for HVAC louvers, elevator doors, mild steel signage cut and drop, holes line up without reaming.
Another list, because bullet points keep you awake.
Rackless drive so no backlash compensation tables
Encoders down to 1 µm resolution
Water cooled stators, ambient in Sharjah hits 45 °C, motors stay below 30 °C*
Cincinnati ditched proprietary boards, now a Beckhoff IPC runs the show. Big touchscreen, gestures like your phone, operators love to zoom the nest, pinch, drag. Import a DXF, apply a job macro, swipe right, cut file posts. Nesting engine runs locally, no cloud, so no one cares if Wi-Fi is dead.
Nitrogen, oxygen, even shop air. I scratched my head when someone in Abu Dhabi insisted on compressed air for 3 mm galv sheet. Turns out the FiberMax torch handles it as long as pressure hits 15 bar. For stainless, stick with nitrogen, edge tint stays minimal.
Trumpf TruLaser 3030 pulls slightly higher dynamics yet asks for their own resonator service crew, pricey flights to UAE. Bystronic ByStar Fiber pushes to 12 kW like the top FiberMax but Bystronic pallets need deeper pit. Mazak Optiplex Nexus is fine though its control feels dated, still Windows XP skin. FiberMax lands in the sweet spot, decent speed, flat learning curve, and domestic USA parts availability that ship via FedEx in 48 h.
FiberMax is not one model, think family.
All share spindle head, optics, software, so a shop running mixed sizes trains operators once.
Power draw sits around 32 kVA steady when the 6 kW source is full juice. Add the chiller, another 8 kVA. Keep that in mind, some listings forget auxiliaries. Cooling water loop sits at 23 °С. If your plant AC fails, at least the chiller shouts long before diode bricks overheat.
Diode MTBF rated 100 000 h, yeah, brochure talk, in real life expect 60 000 h until noticeable power fade. Cutting head lenses last 250 pierces on 25 mm steel then wipe, maybe swap every 1 500 pierces. Filters in the dust collector need swapping every 600 hours according to three shops I bugged on WhatsApp.
A nozzle is 15 USD, a lens about 250 USD, plate of kerf that sits in the drawer costs nothing compared to late delivery.
Shipyards in Ras al Khaimah, facade players in Dubai Investment Park, and sprinkler pipe subcontractors in Ajman. They chase fast turnaround on everything thinner than 25 mm. The FiberMax drops parts that go straight to bending on a CI press brake, same brand synergy, one service hotline.
I like it, sometimes hate the fan noise, yet respect the way Cincinnati keeps bolts imperial but ships a metric Allen set in the tool kit, thoughtful. The machine makes sense if you push mixed batches, night shift unattended for 8 hours, need reliable pallets, not babysitting optics.
Cincinnati stacks nearly 400 FiberMax units each year across two plants. This is version 4 of the chassis, minor weld stiffeners added in 2022 after frame twist reports. Issues addressed, no drama.
Fabricators in the Emirates keep picking the FiberMax because it slices stainless fast, survives hot shop floors, and does not lock them into exotic service contracts. End of rant, hope it helps.
