07F051 - Walter Drum-Soft Pneumatic Wheel for Line-Mate II

Precision Linear Finishing with Walter Drum-Soft Technology

The Walter 07F051 Drum-Soft is an essential accessory for metal fabrication professionals utilizing the Line-Mate II or Line-Mate III linear finishing systems. Engineered to bridge the gap between aggressive grinding and delicate surface conditioning, this 5-3/8" drum utilizes an advanced air cushion design. Unlike solid rubber drums that can transfer excessive vibration and pressure points to the workpiece, the Drum-Soft provides a compliant backing for cloth abrasive belts. This compliance is critical when working with high-value materials like stainless steel, where surface consistency is paramount.

One of the most significant technical challenges in linear finishing is heat management. Excessive friction can lead to heat tinting or warping of thin-gauge metals. The Drum-Soft addresses this by allowing the abrasive belt to flex, increasing air flow and reducing the rigid friction that generates heat spikes. Furthermore, the cushioned support effectively eliminates "edge cutting"—a common defect where the hard edge of a drum digs into the material, creating deep scratches that are difficult to remove. This ensures that the grain structure of the finish remains uniform from the center of the pass to the edges.

Designed with productivity in mind, the unit features an integrated 5/8"-11 internal thread. This standard arbor size ensures secure, direct mounting to the Line-Mate spindle without the need for additional adapters or tools. By maintaining optimal contact pressure and reducing heat, the Drum-Soft not only improves the aesthetic quality of the finish but also significantly extends the service life of your abrasive belts, reducing consumable costs over time.
