20 kW Dual‑Table Fiber Laser Cutting System for Heavy Plate with ±45° Bevel

Maxim Ageev, Service Engineer at OOO “MAK” (Russia), submitted a detailed technical specification for a 20 kW fiber laser cutting machine for metal processing. The specification defines a heavy‑duty plate cutting system with a 6000 × 2000 mm vertical cutting area, a 6000 × 1500 mm bevel cutting area (±45°), a table load capacity of at least 5000 kg, dual automated shuttle tables, and cutting capability up to 50 mm carbon steel and 40 mm alloy steel in straight cuts, plus 40 mm carbon steel and 30 mm alloy steel with a ±45° bevel.

YIHAI LASER responded with the YC‑20060‑20kW heavy‑duty gantry laser cutting machine, configured with an ytterbium‑doped fiber laser, a back‑reflection‑protected autofocus cutting head, liquid cooling with temperature monitoring, FSCUT CNC control running HypCut software, CypNest nesting software, and a fully Russian‑language operator interface. This article documents the proposed configuration and its compliance with each technical requirement.

Customer Requirement Analysis

OOO “MAK” operates in an industrial environment where thick steel plate is processed into structural components requiring weld preparation. The key technical demands are:

1. Large work envelope. 6000 × 2000 mm straight cutting, with the bevel area reduced to 6000 × 1500 mm to accommodate the additional X‑axis travel required for the bevel head tilt at the sheet edges.
2. High table load. 5000 kg capacity means the machine will process plate stacks or single plates up to 50 mm thick over the full area.
3. Dual automated shuttle tables. Reduces loading downtime; while one table is cutting, the second is loaded or unloaded.
4. 20 kW laser power. Required for clean, dross‑free cutting of 40–50 mm carbon steel at production speeds.
5. ±45° bevel cutting. Eliminates a separate edge preparation operation for weld bevels.
6. Full safety and monitoring. Light barriers, cabin protection, collision avoidance, lens condition monitoring, and nozzle cooling.
7. Russian interface. All control screens and documentation must be in Russian.

Cutting Performance Parameters

The table below provides representative cutting speeds for the YC‑20060‑20kW with oxygen assist on carbon steel and alloy steel. Actual speeds will be validated during commissioning on the customer’s material.

Material	Thickness (mm)	Assist Gas	Straight Cut Speed (m/min)	Bevel Cut Speed (m/min, 45°)
Carbon steel S355 / S275	20	Oxygen	2.2	1.5
Carbon steel	30	Oxygen	1.4	1.0
Carbon steel	40	Oxygen	0.9	0.6
Carbon steel	50	Oxygen	0.7	—
Alloy steel (S460)	20	Oxygen	1.8	1.2
Alloy steel	30	Oxygen	1.1	0.8
Alloy steel	40	Oxygen	0.8	0.5

For stainless steel and other alloys, nitrogen or air parameters are available in the preloaded process library. The FSCUT controller automatically selects the correct parameter set based on material, thickness, and cut type.

Software, Control, and Safety Systems

FSCUT CNC with HypCut provides real‑time cutting path control, automatic focus, gas pressure regulation, and edge detection. The Russian interface covers all operator screens, diagnostics, and alarm messages.

CypNest is included for offline nesting and programming. The technologist’s PC, supplied with the machine, runs CypNest for sheet utilization optimization, cutting sequence planning, and graphical preview. Part color‑coding shows different processes (straight cut, bevel, marking).

Safety systems include full cabin enclosure, light barriers at the loading positions, emergency stop buttons, laser safety interlocks, and operator goggles with OD6+ optical density. The control system integrates collision avoidance—based on capacitive sensor feedback and head retraction—to prevent nozzle damage from tipped parts.

Frequently Asked Questions

Does the YC-20060-20kW meet the 6000×1500 mm bevel cutting area requirement?
Yes. The gantry travel is sized so that the bevel cutting head can access the full 6000 mm length and 1500 mm width at ±45°. The reduced bevel width compared to the 2000 mm straight-cut width accounts for the additional X-axis travel required for the tilted head at the sheet edges.

Can the machine cut 50 mm carbon steel with a clean edge?
Yes. The 20 kW fiber laser with oxygen assist cuts 50 mm carbon steel at approximately 0.7 m/min with acceptable edge quality. Bevel cutting is supported up to 40 mm carbon steel and 30 mm alloy steel at ±45°.

Is the operator interface available in Russian?
Yes. The FSCUT control system, HypCut software, and CypNest nesting software are supplied with a full Russian language pack. All operator screens, alarm messages, and documentation are in Russian.

What safety features are included?
The machine includes full cabin protection, light barriers, emergency stop buttons, laser safety interlocks, collision avoidance, lens condition monitoring, and operator safety glasses with OD6+ optical density. A voltage stabilizer and compressor are also included.
