CUTTING ALUMINUM PROFILES: THE CHOICE OF LUBRICANT MAKES THE DIFFERENCE

When cutting aluminum profiles, lubricant is not just a process detail: it is a decisive factor in cut quality, production continuity, and tool life.

Extruded aluminum alloys dissipate heat quickly, but they also tend to adhere to the tool, leading to the so-called built-up edge. When this happens, cut quality declines, tool wear increases, and overall process efficiency suffers.

That is why selecting a specific, stable, high-performance lubricant is essential.

To make a real difference in this process, an effective lubricant must deliver:

✔️ High lubricity, to reduce friction, chip adhesion, and tool wear
✔️ Effective cooling, to keep the process stable even under demanding conditions
✔️ Clean chip evacuation and controlled evaporation, to avoid sticky residues and keep the cutting area cleaner
✔️ Compatibility with surface finishes, to protect aluminum even when heat treatments or anodizing are involved
✔️ A formulation free from aggressive additives, such as chlorine or active sulfur, to help prevent corrosion and unwanted alterations
✔️ Safety and sustainability, thanks to low toxicity and good microbiological stability

Choosing the right lubricant means achieving cleaner, more consistent cuts, reducing machine downtime, protecting operators, and enhancing the value of the finished component.

At Motultech Baraldi, we combine application expertise, high-performance products, and a consultative approach to help extruders and machine shops identify the right lubricant and turn every technical choice into a concrete competitive advantage.
