07T534 - Walter Line-Mate High Polish Belt 5-3/8 Inch

Technical Overview of the Walter 07T534 High Polish Drum Belt

The Walter 07T534 High Polish Drum Belt is a specialized abrasive accessory engineered for the final stages of metal surface conditioning. Manufactured by Walter Surface Technologies, this belt is designed to be mounted on pneumatic drums, specifically those compatible with the Line-Mate III linear finishing system. The belt measures 5-3/8 inches in width and 11-5/8 inches in length (circumference), providing a substantial surface area for consistent linear finishing. Unlike coated abrasive belts that use aluminum oxide or zirconia grain to remove material, this high-polish belt is constructed from a soft, durable carrier material intended to hold polishing compounds.

This product is strictly a finishing tool. It does not have an inherent grit rating because its abrasive action is derived entirely from the polishing paste applied to it during operation. It is compatible with various grades of polishing pastes, including Walter's white paste for bright finishes and blue paste for mirror finishes. The belt's seamless construction is a critical technical feature; it eliminates the "chatter" marks often associated with seamed belts, ensuring a perfectly uniform surface profile. This is particularly important when working towards high-specification finishes where even microscopic imperfections are visible.

In industrial applications, the 07T534 is the standard solution for achieving #8 mirror finishes on stainless steel. It is widely used in the fabrication of food processing equipment, pharmaceutical vessels, and architectural metalwork where sanitary and aesthetic requirements are stringent. The belt effectively refines the scratch pattern left by previous conditioning steps (typically up to a 320 grit or finer) and buffs the surface to a high reflectivity. Operators should ensure the pneumatic drum is inflated to the correct pressure to secure the belt and provide the necessary cushion for following the contours of the workpiece.

The belt is compatible with a range of non-ferrous and ferrous metals, including steel, stainless steel, aluminum, and brass. Its width allows for efficient processing of large flat surfaces as well as rectangular tubing. When integrated into a proper finishing schedule—starting with graining belts and moving through conditioning discs—the 07T534 serves as the final, critical step in the Walter surface finishing workflow.
