Gantry Fiber Laser Cutting Machines for Thick Steel Plate

TANAKA gantry fiber lasers cut medium to thick steel plate. Models run at 6, 12, 20 and 40 kW and cut mild steel up to 63.5 mm (2.5") at 40 kW on the FMZIII, or 40 mm (1.57") at 20 kW. They are built for fabricators, steel service centers and OEMs. TANAKA built the first gantry laser cutting machine in 1989, and TANAKA America has 35 years in North America.

All models: cutting width 2,600 to 5,600 mm (8.5' to 18.3'). Cutting length is unlimited because the machine runs on rails. Stainless and aluminum reach the same maximums when cut with nitrogen at 1 MPa or more.

Why gantry

Why Gantry Format for Large and Thick Plate

On a gantry laser, a bridge travels on rails over a large fixed table. Heavy plate stays put while the cutting head moves, so long and wide plates are routine. Need more length? Add rail.

TANAKA built the first gantry laser cutting machine in 1989.

Cutting thin, small parts instead? See our Table Top Laser Cutting Machine, built for thin and small components and medium-to-high production volumes.

Cut quality

Thick-Plate Cut Quality and Productivity

  • TANAKA torch technology, engineered in Japan, with advanced gas control
  • Torch head with flexible optics for fast, easy laser beam adjustment
  • Nitrogen and Continuous Wave (CW) cutting on the FMRIII
  • Options: automatic nozzle changer/cleaner and automatic nozzle centering
  • Cuts mild steel, stainless steel and aluminum

2-3xthe productivity

Replacing a CO2 Laser or Moving Up from Plasma

Replacing an older TANAKA CO2 laser with a 20 kW fiber laser can deliver 2 to 3 times the productivity.

Cutting plate with plasma today? A fiber laser can take over some of that work, and the FMZIII is designed to replace plasma for quality cutting. Plasma still suits some jobs, and TANAKA's CNC plasma pipe and profile cutters are plasma machines. Our fiber lasers are for plate.

Weld prep

Bevel Cutting for Weld Prep (FMZIII)

The FMZIII is TANAKA's bevel fiber laser. It cuts V bevels on the top and bottom of the plate, up to 32 mm at 30° and 28 mm at 45° at 20 kW, and up to 50 mm (1.97") at 45° at 40 kW, so parts can come off the table with less grinding and edge prep before welding.

Fiber Laser FAQs

A gantry fiber laser uses a bridge-style gantry that travels over a large fixed table, so it handles long, wide, medium-to-thick steel plate. TANAKA built the first gantry laser cutting machine in 1989, and TANAKA America has 35 years in North America.

Maximum straight-cut thickness in mild steel is 63.5 mm (2.5") at 40 kW on the FMZIII, 40 mm (1.57") at 20 kW, 30 mm (1.18") at 12 kW and about 20 mm (0.79") at 6 kW. The FMZIII bevel laser cuts V-bevels up to 32 mm at 30 degrees and 28 mm at 45 degrees at 20 kW, and up to 50 mm (1.97") at 45 degrees with the new 40 kW oscillator. Cutting width runs 2,600 to 5,600 mm, and length is extended by adding rail.

Match the power to your thickest and most common plate. As a guide, maximum straight-cut thickness in mild steel is 63.5 mm (2.5") at 40 kW on the FMZIII, 40 mm (1.57") at 20 kW, 30 mm (1.18") at 12 kW and 20 mm (0.79") at 6 kW. Send us a drawing or a part and we'll recommend a model and run a test cut. The FMZIII bevel laser is also available with 40 kW, which cuts 25 mm at 4,700 mm/min and 45° V-bevels up to 50 mm (1.97").

Mild steel, stainless steel and aluminum. With high-pressure nitrogen, stainless and aluminum cut up to 30 mm (1.18") at 12 kW and 40 mm (1.57") at 20 kW. Actual results depend on material grade and condition, so we recommend a test cut on your parts.

Yes. The TANAKA FMZIII bevel fiber laser cuts V bevels on the top and bottom of the plate, up to 32 mm at 30 degrees and 28 mm at 45 degrees at 20 kW, and up to 50 mm (1.97") at 45 degrees with the new 40 kW oscillator, which can cut out secondary grinding and edge prep before welding.

Yes. Replacing an older TANAKA CO2 laser with a 20 kW fiber laser can deliver 2 to 3 times the productivity. Send us a part and we will run a test cut so you can see the difference on your own material.

Yes. TANAKA offers automation and storage systems for loading, unloading, storage, picking and sorting. See our automation and storage systems page for options.
