✅ RR5240 400mm Wet Wide Belt Sander – Product Overview

400宽水磨微信图片_20220221144043400宽水磨

The RR5240 Wet Wide-Belt Sander is a high-performance industrial grinding and finishing machine designed for the deburring, slag/dross removal, oxide skin removal, edge rounding, and surface finishing of metal sheets and parts. With a 400mm working width, this machine features two sanding heads working under a water bath system, which provides effective cooling and dust suppression during processing.

This model is especially suitable for heat-sensitive materials like stainless steel, thin metal sheets, aluminum, and mixed metals, preventing deformation and discoloration during grinding or polishing.


✅ Key Features & Advantages

  • Two High-Powered Sanding Stations: Equipped with two sanding heads, the RR5240 delivers superior deburring and surface conditioning in a single pass.

  • Water Bath Process: Full water circulation reduces heat, prevents workpiece distortion, and minimizes dust and sparks.

  • Ideal for Heat-Sensitive Materials: Excellent for processing stainless steel, thin metals, and soft non-ferrous alloys without risk of burning or warping.

  • Heavy-Duty Industrial Design: Robust frame structure ensures stable and vibration-free operation, improving processing precision.

  • Consistent Finishing Quality: Achieves uniform surface textures from coarse grinding to fine graining finishes.

  • Minimal Consumable Cost: Wet grinding reduces abrasive belt wear and extends consumable life.

  • Optional Magnetic Worktable: Securely holds magnetic materials during processing, allowing for precise handling of small or thin parts.

  • User-Friendly Operation: Intuitive controls, adjustable conveyor speed, and easy maintenance access reduce labor training requirements.


✅ Machine Functions

  • Deburring: Efficient removal of burrs left after laser cutting, punching, or shearing processes.

  • Slag & Dross Removal: Effective in removing slag and dross from plasma or flame-cut components.

  • Oxide Removal: Strips oxide layers and discoloration from cut edges, improving further processing like welding or painting.

  • Surface Conditioning: Prepares surfaces for downstream processes such as coating, welding, or assembly.

  • Edge Rounding: Light edge rounding effect with fine abrasive belts to improve part safety and coating adhesion.

  • Brushing Finish (Optional): With additional brushing units, the machine can achieve decorative finishes like satin or hairline textures (if required in customized configurations).
