Industrial knives for cutting aluminium

Because of its ductility, aluminium demands extreme precision to avoid marks and burrs:

• Mirror finish: circular and straight knives ground to tolerances of ±0.001 for a clean cut.
• Non-stick: coatings and treatments that prevent aluminium from adhering to the edge.
• Bespoke solutions: we optimise the cutting angle according to the alloy.

We manufacture specific knives for aluminium, with selected hardness and material and tolerances down to the micron:

• Material selection: base steel chosen according to the alloy, to prevent adhesion and premature wear.
• Micron precision: tolerances that guarantee a perfect fit in the knife holder and a burr-free cut.
• Optimised hardness: heat treatments that withstand constant friction without damaging the edge.

• Maximum cutting precision: superior finish on the sheet edge.
• Tolerance and hardness customised to your production.
• Bespoke configuration, including single-edge knives.
• High durability: fewer changes and lower cost per cut.
• Mirror grinding for lacquered or high-gloss aluminium sheets.

We cover all industrial aluminium cutting:

• Aluminium service centres: slitter knives for precision coils and strips.
• Automotive and aerospace: cutting panels and parts with micron tolerance.
• Construction and architecture: profiles and sheets for façades, with a clean cut.
• Packaging: cutting foil and thin aluminium sheet.

Why is precision key?

In aluminium sheet cutting, a tiny deviation can ruin an entire batch:

• Non-stick: the right grinding and material reduce the friction that sticks aluminium to the edge.
• Edge quality: micron tolerance means the aluminium is cut rather than torn.
• Process stability: uniform knives that allow high speeds without vibration.
