Cms Brembana Sprint Jet 5-Axis Sawjet

The CMS Brembana Sprint Jet is a numerically controlled five-axis sawjet designed for flexible and high-output slab processing.

It combines a rotating and tilting diamond blade with an integrated abrasive-waterjet cutting head. The blade performs fast straight, shaped, vertical, inclined and mitred cuts, while the waterjet completes internal corners, intersecting cuts, small radii and complex details that cannot be produced efficiently with the blade alone.

This combination allows kitchen worktops, vanity tops, architectural panels and other complex components to be completed within one coordinated production program.

The five interpolated axes allow the cutting head to rotate and incline throughout the machining cycle. The blade and waterjet can therefore approach the material from multiple angles, enabling accurate straight cuts, mitres, angled work and detailed internal shapes.

The Sprint Jet has an X-axis stroke of 4250 mm and a Y-axis stroke configurable from 3200 to 7200 mm. This gives it the capacity required for large-format slabs and production layouts tailored to the customer’s factory.

The fixed-table, open-frame construction is installed on concrete or fabricated support shoulders. This robust structure provides the stiffness and stability required for demanding cutting applications and long-term production use.

The Sprint Jet uses diamond blades from 350 to 625 mm in diameter. With the blade at 90°, the machine can process material up to 200 mm thick. At 45°, the maximum published working thickness is 130 mm.

The abrasive-waterjet system works in combination with the blade rather than replacing it. Long straight sections are completed quickly with the diamond blade, while the waterjet is used only for detailed sections, internal corners and interfering cuts.

This approach can reduce waterjet cutting time and abrasive consumption compared with processing the entire component exclusively by waterjet.

The five-axis waterjet head can be equipped with CMS IKC technology. Intelligent Kerf Compensation controls cutting taper and head deflection, helping achieve accurate mitred and bevelled waterjet cuts.

The machine can be supplied with high-pressure intensifiers from 22.5 to 45 kW, depending on the required production capacity and material range.

An electronic abrasive hopper automatically regulates abrasive flow to the cutting head. If the flow is interrupted, the system can stop the cut to reduce the risk of damaging the material.

Available abrasive-management options include a 330 kg pressurised supply system and a larger two-stage system with a capacity up to 2000 kg for long, uninterrupted cutting cycles.

The working tank can be prepared for an automatic dredging system. This removes spent abrasive from the tank and significantly reduces the manual maintenance normally associated with waterjet cutting.

An optional vacuum manipulator can automatically lift and reposition cut pieces. This supports optimised slab layouts, reduces manual handling and allows the machine to complete interfering cuts automatically.

CMS states that automated component repositioning can improve productivity by up to 33% by reducing manual movements during slab cutting. Actual performance depends on the material, slab layout, component geometry and machine configuration.

The Sprint Jet can also be configured with an automatic pallet-changing system. One slab can be loaded outside the cutting area while another slab is being processed, reducing loading and unloading delays.

In the CMS brochure’s example comparison, the standard Formax Jet or Sprint Jet processes approximately 81 m² or 15 slabs during an eight-hour shift, while the pallet-change version processes approximately 151 m² or 28 slabs. CMS notes that these figures are indicative and vary with material, thickness, blade, pump and production conditions.

Other production configurations include pendular working areas, automatic unloading, roller integration and complete automated slab-processing lines.

CMS Smart Saw software supports manual, semi-automatic and automatic cutting, including single, multiple, circular, horizontal and parametric operations.

EasySTONE CAD/CAM can be used for advanced blade and waterjet programming, nesting, drilling, milling, profiling, engraving and three-dimensional work. The software supports common 2D and 3D file formats and provides a simulation of the machining cycle before cutting begins.

Optional slab photography captures the actual material surface for nesting, defect avoidance, pattern positioning and vein matching.
