The Cutting-2518 Pro-3/6 is a high-capacity automatic corrugated board cutting machine, available in a 3 or 6 paper-library configuration, with a patented design of 7 longitudinal knives and 1 transverse knife that allows 30% more box types to be produced than standard industry machines. Designed for plants with varied orders and high material-flexibility requirements, this automatic corrugated board cutting machine processes corrugated board with widths up to 2.550 mm and thicknesses of 2,5–6,5 mm, producing box blanks with a minimum thickness of 18 mm at an efficiency of 3,5–10 pcs/minute.
Compared with the standard Cutting-2518 model with 4 fixed libraries, the Cutting-2518 Pro-3/6 automatic corrugated board cutting machine offers maximum flexibility in material management — the 6-library configuration allows the storage and automatic selection of 6 different types of corrugated board simultaneously, with no manual intervention when changing the material type between orders. Combined with one-click knife adjustment and an optimized cutting path for maximum board savings, the Pro-3/6 is the top solution in the Cutting-2518 family for plants with a complex portfolio of formats and materials.
Key advantages of the Cutting-2518 Pro-3/6 automatic corrugated board cutting machine
• 3 or 6 paper libraries — maximum material flexibility — the Pro configuration of the Cutting-2518 machine allows the simultaneous storage of 3 or 6 different types of corrugated board (different thicknesses, grammages, flute structures), with automatic selection of the right material for each order without manual changing of the roll or board sheet between orders.
• Design of 7 longitudinal knives + 1 transverse knife — 30% more box types — compared with standard industry machines with 5–6 longitudinal knives, the Cutting-2518 Pro-3/6 machine uses 7 longitudinal knives plus 1 dedicated transverse knife, allowing 30% more cutting combinations on the same sheet and therefore more box types that can be produced without additional operations.
• One-click knife adjustment — a box-format change is performed with a single click from the control panel; the system automatically reconfigures the positions of all 7 longitudinal knives and the transverse knife to the new dimensions, with no manual mechanical adjustments and no significant downtime between orders.
• Optimized cutting path — maximum board savings — the internal algorithm of the Cutting-2518 machine automatically calculates the optimal cutting path to minimize material waste on each order, reducing the material cost per blank compared with non-optimized cutting.
• Continuous processing at fixed size — the continuous processing system ensures uninterrupted production of foldable corrugated board blanks at the set sizes, with no stops for adjustments during a run, maximizing the effective productivity per series.
• Board pressing with free knife — constant accuracy — the free-knife pressing system keeps the corrugated board stable in the cutting area without deforming the material, ensuring the geometric accuracy of each cut blank regardless of the thickness of the board processed (2,5–6,5 mm).
• Maximum cutting width 2.550 mm — one of the largest cutting widths available in this category, covering extra-wide corrugated board sheets for large-format boxes used in packaging furniture, household appliances and industrial equipment.
• Minimum box thickness 18 mm — the ability to produce blanks with a minimum thickness of 18 mm makes the Cutting-2518 Pro-3/6 machine compatible with flat packaging and thin components that require boxes with a reduced minimum height.
The Pro-3 and Pro-6 configurations — how to choose the number of libraries
Cutting-2518 Pro-3 — 3 paper libraries
The 3-library configuration of the Cutting-2518 Pro machine is the compact solution for plants that regularly use 3 distinct types of corrugated board — for example, thin single wall (low-grammage CO3), standard single wall and double wall (CO5). The automatic selection between the 3 types eliminates manual material changing on each different order, with a smaller footprint than the 6-library configuration.
Cutting-2518 Pro-6 — 6 paper libraries
The 6-library configuration is the top variant of the Cutting-2518 Pro machine, recommended for plants with a complex customer portfolio that requires varied material specifications — different grammages, different flute structures (B, C, E, BC, EB), thicknesses from 2,5 mm to 6,5 mm — all available simultaneously without any manual intervention. It is the solution for custom packaging production centers where each order may require a different type of board.

The Cutting-2518 Pro-3/6 versus the standard Cutting-2518 model with 4 libraries
Both models in the Cutting-2518 family use the same 7+1 knife design, the same format specifications (300–2.550 mm width, 2,5–6,5 mm board thickness, 18 mm minimum box thickness) and the same efficiency of 3,5–10 pcs/minute. The essential difference is in material management.
The standard model with 4 libraries offers a good balance between versatility and cost for plants with a relatively homogeneous range of board types. The Cutting-2518 Pro-3/6 machine is the choice when the plant regularly uses more than 4 types of board, when orders frequently vary in material specifications, or when the complete elimination of manual interventions for material changing between different orders is desired. UZINEX provides free consultancy for selecting the optimal configuration.
Applications and industries for the Cutting-2518 Pro-3/6 automatic corrugated board cutting machine
The Cutting-2518 Pro-3/6 machine is intended for custom packaging plants and manufacturers that manage orders with varied material specifications, where manual selection of the board type between different orders generates downtime and a risk of material errors. With 6 libraries available simultaneously and automatic selection, the Pro-6 completely eliminates this problem.
Packaging production centers for ecommerce and fulfillment, which receive orders with different specifications from several customers within the same production shift, use the Cutting-2518 Pro-3/6 machine because they can program cutting sequences with different materials without stops for the physical changing of board rolls or sheets.
Manufacturers of furniture, household appliances and industrial equipment that simultaneously use thin board (CO3) for small components, medium board (CO5) for panels and thick board for heavy products find in the Pro-6 configuration of the Cutting-2518 machine the solution that covers all material specifications from a single piece of equipment, without investing in separate machines for each board type.
How the Cutting-2518 Pro-3/6 automatic corrugated board cutting machine works
1. Order identification through QR scanning — each order is identified by scanning the QR code; the system automatically retrieves the format specifications and the required material type from the database, with no manual data entry.
2. Automatic material selection from the library — based on the order specifications, the Cutting-2518 machine automatically selects the corrugated board type from the corresponding library (from the 3 or 6 available), without the operator physically changing the material.
3. One-click knife adjustment — the system automatically reconfigures the positions of the 7 longitudinal knives and the transverse knife to the dimensions of the new order with a single click, with no manual mechanical adjustments.
4. Cutting-path optimization — the algorithm calculates the optimal cutting path to minimize board waste for the selected format and applies it automatically before starting production.
5. Continuous cutting with stable pressing — the Cutting-2518 machine makes the longitudinal and transverse cuts in continuous processing; the free-knife system keeps the board stable in the cutting area without deforming the material.
6. Output of blanks ready for folding or packaging — the cut blanks come out ready for direct transfer to the FQ-P01, FQ-P02, FQ-P03 packaging lines or to folder-gluers from the HS, HX or YF series in the UZINEX portfolio.
