Robotwire EVO Editorial Review
Product Positioning: A Flagship Solution for Complex 3D Profiles
The Robotwire EVO is Pellegrini's flagship product in CNC wire profiling. Seven-axis interpolation combined with 22.5° wire inclination allows it to machine complex 3D components such as cylinders, tapered columns, spiral surfaces and artistic sculptures.
Compared with the 4-axis 2D profiling of the Robot Wire 1600-2600, the EVO's seventh axis typically controls wire tilt or rotation, enabling undercuts, bevels and complex spatial curves.
Key Structure and Specs
The patented arch structure is the Robotwire EVO's signature design. The arch improves overall rigidity and provides enough motion space for large wire-angle tilting, reducing interference risk.
The electronic tensioning system quickly adjusts wire tension during complex contour cutting, adapting to tension fluctuations caused by changing wire angles. Compared with hydraulic tensioning, electronic tensioning responds faster and integrates more easily with the CNC system.
The max working width of 2.6 m and height of 1.7 m accommodate most architectural components and sculptures. However, the official site does not publish main motor power, wire speed or machine weight—parameters critical for electrical supply and workshop layout.
Cutting Performance and Material Compatibility
The Robotwire EVO scores 9.6 overall, with accuracy at 9.7, efficiency at 9.5 and material compatibility at 9.5—near top levels in almost every dimension. The combination of seven-axis interpolation and electronic tensioning maintains high efficiency and surface quality even on complex surfaces.
The 22.5° wire inclination allows the machine to produce undercuts and bevels that traditional monowire saws cannot, such as vase columns, twisted components and artworks with concave shapes. This is highly valuable for premium curtain walls, hotel interiors and artistic creation.
Intelligence scores 9.2, indicating strong program handling and human-machine interaction, but seven-axis programming and process debugging demand highly skilled operators and usually require manufacturer training.
Who It Suits: High-End Architectural Component and Sculpture Processing
The Robotwire EVO best suits processing plants that take high-end architectural components, artistic sculptures and complex shaped-stone orders. These orders typically have high per-piece value and strict accuracy and surface-quality requirements, with customers willing to pay a premium for equipment investment and process capability.
For large stone groups that already own squaring machines, multiwire saws and 4-axis profilers and want to expand into 3D surface machining, the EVO can serve as a technology flagship, enhancing order-taking capability.
If your orders are mainly standard slabs, 2D lines or ordinary block squaring, investing in the EVO would be overkill. Its real value lies in complex 3D profiling, not high-volume standard products.
Pre-Purchase Reminders
- Confirm full power and geometric parameters: the official site omits power, wire speed and machine weight, so request the technical datasheet and foundation drawing before purchase.
- Evaluate programming and training support: seven-axis programming is complex, so confirm whether the manufacturer provides a CAM interface, post-processor, operator training and process database.
- Consider total cost of ownership: beyond the high purchase price, original spare parts, diamond wire, the electronic tensioning system and specialist maintenance staff significantly increase long-term operating costs.

Robotwire EVO Buyer FAQ
Seven-axis interpolation allows the diamond wire to move in multiple orientations in 3D space, while the 22.5° inclination enables undercuts, bevels and complex surfaces.
Typical applications include cylinders, tapered columns, twisted components, vase columns and artistic sculptures.
The EVO is a 7-axis machine for complex 3D profiles; the Robot Wire 1600-2600 is a 4-axis machine focused on 2D profiles.
Choose the EVO if your orders are mainly 3D surfaces; the Robot Wire offers better value for 2D work.
It is mainly intended for complex 3D profiling of marble, granite, sandstone and ornamental stone.
Specific machining strategies need to be adjusted according to material hardness, grain direction and contour complexity.
Seven-axis programming is much more complex than 3/4-axis programming and usually requires CAD/CAM software to generate toolpaths, then a dedicated post-processor to convert them into machine programs.
Confirm whether the manufacturer provides a post-processor, sample programs and operator training when purchasing.
Flagship machines often involve multiple configurations and options; European manufacturers usually place full parameters in technical datasheets.
Request the detailed datasheet and recommended process parameters directly from Pellegrini or an authorized distributor during procurement.
The arch structure, electronic tensioning system, seven-axis drive mechanisms and diamond wire are maintenance priorities.
Because of the high precision, annual service by manufacturer-certified engineers and a stock of wear parts are recommended.
Both are high-end multi-axis profiling machines. The Robotwire EVO stands out for its 7-axis patented arch structure, while the Breton Fuego range (e.g., X4 M, Multiaxis) offers 10-axis interpolation with rotary tables, excelling at architectural components such as cylinders and tapers.
Choose based on the main machining objects and existing process chain.
Robotwire EVO Buying Recommendation
The Pellegrini Robotwire EVO is the most capable CNC wire profiling machine in Pellegrini's lineup.
Seven-axis interpolation, 22.5° wire inclination and the patented arch structure leave few weaknesses in complex 3D profiling. If your plant takes high-end architectural components, artistic sculptures or complex shaped-stone orders and has the budget, floor space and technical team to match, the EVO is a flagship worth investing in. However, if your orders are mainly standard slabs or 2D components, the EVO's capabilities will be severely underutilized and the payback period will be long. Before purchasing, confirm the full specifications, training support and total cost of ownership.
