The WyCut GR Series is a ground-rail laser machine for cutting extra-large format sheets and thick metal plates, designed for the shipbuilding, heavy steel-structure, wind energy and construction-machinery industries where the dimensions and weights of the sheets exceed the capabilities of conventional fixed-bed machines. With cutting formats up to 21000×4000 mm on the GR 2140S model and a maximum load of 15 tonnes, this ground-rail laser machine processes the heavy sheets that cannot be handled on standard machines without the risk of deforming the bed or the guiding system.
The operating principle of the WyCut GR Series ground-rail laser machine is fundamentally different from fixed-bed machines: the gantry travels on ground rails separate from the cutting bed, eliminating the transmission of the sheet's vibrations and heavy loads to the guiding system. The result is superior mechanical stability over long periods of cutting 10–15 tonne sheets, with ±0,3 mm accuracy maintained regardless of the material's weight.
Key advantages of the WyCut GR Series ground-rail laser machine
• Cutting format up to 21000×4000 mm — the largest in the UZINEX portfolio — the WyCut GR 2140S ground-rail laser machine processes sheets with lengths up to 21 meters and widths up to 4 meters, covering all the formats used in shipbuilding, offshore structures, steel bridges and industrial platforms.
• Maximum load 15 tonnes — the ground rails remove the load from the machine bed — the system with ground rails separate from the cutting bed allows the positioning of sheets up to 15 tonnes without transmitting the load to the guiding system, eliminating bed deformation and maintaining alignment during the cutting of ultra-heavy plates.
• Heavy industrial cutting head — carbon steel up to 250 mm, stainless up to 120 mm — the Raytools Germany cutting head for heavy industrial applications allows cutting carbon steel with thicknesses up to 250 mm and stainless steel up to 120 mm — capabilities impossible to achieve with standard fixed-bed machines and 3–30 kW power.
• Automatic feeding system for large-format sheets at 10,000 kg — the automatic feeding system designed for large-format sheets and weights up to 10,000 kg reduces the need for manual crane handling, increasing the safety and productivity of loading-unloading operations.
• Modular frame with high-rigidity thermal protection — HIWIN Taiwan — the extremely rigid modular expansion frame maintains the geometric alignment of the gantry across the extra-large format of up to 21 meters, including in conditions of high thermal variations specific to high-power cutting in large industrial halls.
• Industrial dust extraction system with 80% efficiency over the cutting area — the Donaldson USA system with multiple channels and self-cleaning, at 500 m³/h per motor, ensures efficient extraction of the fumes and particles generated when cutting thick sheets at high power, in compliance with European industrial air-quality regulations.
• Simultaneous left-right cutting with dual laser source — the optional configuration with simultaneous cutting on both sides of the gantry increases effective productivity on symmetric shapes and halves the cycle times on profiles that can be cut in parallel.

When a ground-rail laser machine is necessary instead of a fixed-bed machine
Standard fixed-bed laser machines — including the WyCut S, FE, HP and HS series — process sheets up to 8000–8500 mm long with weights up to 10–14 tonnes on large models. The WyCut GR Series ground-rail laser machine is necessary when any of these limits is exceeded: formats larger than 8500 mm, plates heavier than 10 tonnes, or carbon-steel thicknesses greater than 40–45 mm.
The main mechanical difference — the gantry on ground rails versus the gantry on the machine bed — is not just a format solution but a necessity for stability over long periods of high-power cutting. Cutting a 20-meter profile on 100 mm steel takes tens of minutes; on a fixed-bed machine, the accumulated vibrations and the thermal load on the bed structure would compromise accuracy over the duration of the cycle. The WyCut GR Series ground-rail laser machine maintains alignment throughout the cut, regardless of the cycle length.
Applications and industries for the WyCut GR Series ground-rail laser machine
The WyCut GR Series ground-rail laser machine is intended for industries that process metal sheets of exceptional format and weight. Shipbuilding uses the GR 1428S and GR 2140S models for cutting hull and superstructure sheets — naval steel plates of 20–50 mm in lengths of 10–21 meters, standard dimensions in shipyards that cannot be processed on any other standard laser equipment.
The wind energy industry uses the ground-rail laser machine for cutting the flanges and structural components of wind towers — circular profiles and parts with thicknesses of 50–120 mm made of high-strength steel. Manufacturers of steel bridges, industrial tanks and heavy construction equipment (excavators, cranes, mining machinery) find in the WyCut GR Series the only laser machine that covers the thicknesses and formats specific to these industries.
Laser service centers that serve heavy industry accept orders for formats and thicknesses that standard machines cannot process; the WyCut GR Series ground-rail laser machine opens access to this specific market segment, with carbon-steel thicknesses up to 250 mm and formats up to 21×4 meters.
How the WyCut GR Series ground-rail laser machine works
1. Sheet feeding with a large-format automatic system — the steel sheet or plate of up to 15 tonnes is positioned on the cutting bed with the automatic feeding system designed for weights up to 10,000 kg, minimizing manual crane operations.
2. Gantry travel on the ground rails — the gantry with the cutting head travels on ground rails independent of the machine bed, eliminating the transmission of the sheet's heavy load to the guiding system and ensuring alignment along the entire length of up to 21 meters.
3. Cutting with the heavy industrial Raytools head — the heavy industrial cutting head processes carbon-steel thicknesses up to 250 mm and stainless steel up to 120 mm with ±0,3 mm accuracy, at the 10–15 m/min speed specific to thick sheets at high power.
4. Industrial dust extraction over the cutting area — the Donaldson system with 500 m³/h per motor extracts the fumes and particles generated when cutting large thick sheets with 80% efficiency over the active cutting area.
5. Optional simultaneous left-right cutting — on symmetric profiles, the configuration with simultaneous cutting on both sides of the gantry halves the cycle times, increasing the productivity of the ground-rail laser machine on orders with repetitive symmetric shapes.
