62365 - Pferd POLIFAN Aluminum Flap Disc 5-Inch 40 Grit Type 27

Technical Overview: Pferd POLIFAN Flap Disc for Aluminum

The Pferd 62365 is a specialized abrasive tool within the POLIFAN line, engineered specifically to address the unique metallurgical challenges of grinding aluminum and other non-ferrous metals. Standard abrasives often fail when applied to soft, ductile materials due to a phenomenon known as "loading" or "clogging," where the removed material adheres to the abrasive grain and fills the void spaces. This renders the disc ineffective and generates excessive heat. The Pferd Aluminum line incorporates active fillers and a specialized coating composition that drastically reduces chip adhesion, ensuring the grain remains open and aggressive throughout the service life of the disc.

This particular model features a Type 27 (flat) profile, which is optimized for surface grinding applications where the tool is held at a shallow angle (typically 0 to 15 degrees) relative to the workpiece. The 5-inch diameter provides a balance between coverage area and maneuverability, while the 7/8-inch arbor ensures compatibility with the vast majority of industrial angle grinders. The 40 grit specification indicates a coarse abrasive texture, designed for high stock removal rates. This makes it an ideal choice for leveling welds, removing heavy burrs, or shaping aluminum components rapidly.

Thermal management is a critical aspect of grinding aluminum, as the material has a lower melting point than steel and is prone to warping or discoloration under heat stress. The Pferd 62365 is formulated to cut cool, minimizing thermal transfer to the substrate. This "cool grinding" characteristic not only protects the metallurgical integrity of the workpiece but also prevents the glazing of the abrasive material. By combining a robust backing plate with high-quality abrasive flaps, Pferd delivers a tool that offers consistent performance, reduced vibration, and superior longevity compared to conventional discs when used in appropriate applications.

Operators in aerospace, shipbuilding, and automotive fabrication sectors rely on the consistency of Pferd abrasives. The construction of the flap disc allows for the continuous exposure of fresh, sharp grain as the flaps wear down, maintaining a consistent cut rate from the first spark to the last. This self-sharpening mechanism, combined with the anti-loading technology, results in significant time savings and reduced consumable costs in high-volume production environments.
