Thick-Plate Fiber Laser Cutting
High-Power Fiber Laser Cutting Machine
This machine exists for one reason: to carry a high-power laser without losing the accuracy that makes laser cutting worth choosing. From 6000W to 30000W, it cuts plate from roughly 30 mm to 80 mm, holds ±0.3 mm per metre, and accelerates at 2.0G. A welded, annealed bed and a 250 mm Z axis are what let it take the power.

Built to Take the Power
Why Thick Plate Needs Its Own Platform
Putting a very high-power source on a light machine is not the answer. The frame flexes, the gantry deflects and accuracy pays for it. This platform is engineered around the laser, so the structure matches the energy going through it.
- Machine tool for high powerDesigned from the start to withstand a high-power laser, with a wide, flexible table that suits varied heavy work.
- Clean, low-smoke cuttingAn advanced no-smoke cutting approach keeps the process cleaner, so heavy fabrication stays practical indoors.
- Welded, annealed bedTube-welded frame through high-temperature annealing and secondary vibration ageing, releasing internal stress for lasting strength and accuracy.
- Reinforced gantryA lightweight aluminium beam tuned for dynamic performance, moving fast and smoothly without giving up rigidity.

Material & Thickness
Material Limits From 6KW to 30KW
The same table serves every metal; the parameter set and gas follow the material and the thickness.
| Material | Power band | Maximum thickness |
|---|---|---|
| Carbon steel | 6KW–30KW | ≤25 mm |
| Stainless steel | 6KW–30KW | ≤80 mm |
| Aluminium | 6KW–30KW | ≤60 mm |
| Brass | 6KW–30KW | ≤22 mm |
A
Heavy Fabrication
Structural plate, bases and connection plates where thickness and a square edge matter more than decoration.
B
Stainless & Aluminium Plate
Vessels, flanges and machine frames cut from thick stainless and aluminium, where a clean cut face reduces finishing.
C
Flame and Plasma Replacement
A cleaner, more accurate alternative to thermal cutting on heavy work, without the heat-affected edge.
Operating Routine
From Plate to Part in Four Steps
Heavy stock changes the handling, not the process: load, set the parameters, cut, unload.
01
Load the Plate
The thick plate is positioned on the table, with the Z axis raised to give clearance for the stock.
02
Set the Parameters
Power, focus and gas are recalled for the material and thickness before the cut begins.
03
Cut
The head cuts at up to 2.0G acceleration while zone-specific extraction draws fume at the source.
04
Unload and Check
Heavy parts are removed and the first piece is checked for edge squareness before the batch is released.
Where It Earns Its Place
Heavy Fabrication Sectors That Cut Thick
These industries need long, thick and accurate cuts, and often need to replace flame or plasma to get them.
Shipbuilding & Marine
Deck plate, stiffeners and marine fittings where thick sections and long cuts are routine.
Automotive & Elevator
Chassis brackets, counterweights and lift components cut from plate with repeatable accuracy.
Machinery & Energy
Machine bases, oil-field hardware and process plant plate where a clean edge saves machining time.

FAQ
High-Power Cutting Questions
The platform is designed for plate from about 30 mm to 80 mm. At the material level the 6KW to 30KW band cuts carbon steel up to 25 mm, stainless steel up to 80 mm, aluminium up to 60 mm and brass up to 22 mm. Stainless and aluminium carry the greatest thickness on this platform.
Three models are offered: KR6025 with 6000 x 2500 mm travel, KR8025 with 8000 x 2500 mm travel and KR12525 with 12500 x 2500 mm travel. Every model supports laser power of 6000W, 12000W, 15000W, 20000W or 30000W.
Thick sections need more energy to cut cleanly at a usable speed. Higher power keeps the cut face tidy and the cycle short on heavy stock, and the machine is built specifically to carry that power, with a rigid bed, a reinforced gantry and a 250 mm Z travel to suit thick material.
Carbon steel up to 25 mm, stainless steel up to 80 mm, aluminium up to 60 mm and brass up to 22 mm across the 6KW to 30KW range. The platform is also used as a clean alternative to flame and plasma cutting on heavy fabrication.
Rapid traverse runs at 155 m/min to 180 m/min and maximum acceleration reaches 2.0G, so repositioning between heavy cuts is quick despite the size of the machine.
The machine uses zone-specific exhaust technology. A motion control mechanism activates suction precisely in the cutting area, so airflow is stronger and more concentrated for dust and particle removal, which improves the working environment while reducing energy use.
The high-power machine carries a 2-year warranty on parts and labour with lifetime engineering support by email, WhatsApp and remote desktop. Volume terms are agreed per order.
