OVERVIEW

Technical Overview of the Pferd POLIFAN Aluminum Flap Disc

The Pferd 62367 is a high-performance abrasive tool engineered specifically for the challenges of working with soft, ductile materials like aluminum and other non-ferrous metals. Standard abrasives often fail rapidly on these materials due to "loading," a phenomenon where the removed material adheres to the abrasive grain and fills the void spaces, effectively smoothing the disc and halting the cutting action. This POLIFAN disc utilizes a specialized filler and coating system that actively prevents chip adhesion, ensuring the grain remains exposed and effective throughout the service life of the tool.

This specific model features a Type 27 (flat) profile, which is optimal for grinding at lower angles (0 to 15 degrees). This geometry allows for excellent control during blending and finishing operations on flat surfaces. The 5-inch diameter combined with a standard 7/8-inch arbor ensures compatibility with a wide range of industrial angle grinders. With an 80 grit rating, this disc is classified for intermediate to fine finishing work. It is capable of removing light weld seams or surface imperfections while leaving a smooth finish suitable for subsequent processing steps such as painting or anodizing.

Thermal management is another critical aspect of the Pferd 62367's design. Aluminum has a relatively low melting point, and excessive heat generation during grinding can lead to structural changes or surface discoloration. The active grinding agents in this disc help reduce friction and heat buildup, protecting the workpiece integrity. For industrial MRO environments where aluminum fabrication or repair is common, this specialized consumable reduces downtime associated with frequent disc changes and improves overall process efficiency.

FAQ

This disc contains special fillers and coatings designed specifically for soft metals like aluminum. These additives prevent the metal shavings from sticking to (loading) the abrasive grains, which is the primary cause of failure in standard discs when used on aluminum.

Type 27 discs have a flat profile, making them ideal for blending and finishing on flat surfaces at lower grinding angles (0-15 degrees). Type 29 discs are conical/angled, which provides more aggression for stock removal and contour work.

While it physically can grind steel, it is not recommended. The abrasive is optimized for soft metals and may wear prematurely on hard steel. Additionally, using the same disc on both steel and aluminum can cause cross-contamination, leading to corrosion issues on the aluminum (galvanic corrosion).

This disc is designed for 5-inch angle grinders with a standard 7/8-inch arbor (unthreaded).

80 grit is considered a medium-fine grit. It is better suited for blending, smoothing, and finishing. For heavy stock removal or grinding down large welds quickly, a coarser grit like 40 or 60 would be more efficient.

No, flap discs have an integrated backing plate (usually fiberglass or plastic) and do not require a separate backing pad like fiber discs do.

Loading occurs when the soft aluminum melts slightly from friction and adheres to the abrasive grains. This covers the sharp edges of the grit, causing the disc to stop cutting and start rubbing, which generates excessive heat.
