Product Introduction:

The RRR5340 Wet Wide Belt Sander is a high-performance industrial sanding machine specially designed for deburring, oxide removal, slag/dross removal, edge rounding, and surface finishing of metal sheets and components. This model comes with three heavy-duty sanding heads, a 400mm working width, and operates entirely in a water bath process for optimal cooling, reduced heat generation, and enhanced abrasive life.

Equipped with a PLC touch screen control system, operators can easily manage operational parameters, adjust belt speeds, and monitor the entire production process with precision. The conveyor system, optionally available with magnetic support, ensures stable feeding of small metal parts, making it a perfect solution for small to medium-sized metal fabrication workshops.

This machine delivers a high-quality satin or grain finish and ensures safe, consistent, and precise material removal without the risk of discoloration or thermal distortion, especially on stainless steel and heat-sensitive metals.


✅ Key Features:

  • Three Sanding Heads: Offers multi-stage processing for effective dross removal, oxide cleaning, edge rounding, and surface finishing in a single pass.

  • Wet Sanding Technology: Water-cooled sanding significantly reduces heat build-up, prevents material discoloration, and controls dust for a safer working environment.

  • PLC Touch Screen Interface: Simplifies operation, allowing precise control of sanding pressure, belt speed, and conveyor speed, with production data tracking.

  • 400mm Working Width: Compact but versatile, suitable for a wide range of part sizes from small components to medium-sized sheets.

  • Heavy-Duty Build: Designed for high workload environments, built with a reinforced structure ensuring durability and long-term performance.

  • Adjustable Conveyor Speed: Flexible feed rate settings (0.5-6 m/min) for different finishing requirements.

  • Water Circulation System: Equipped with a filtration system to extend water usability and reduce maintenance.

  • Optional Magnetic Conveyor: Enhances processing of small-sized ferrous metal components by preventing workpiece slippage.

  • Energy-Efficient System: Reduces consumable costs and power consumption, delivering low operational cost per part.


✅ Main Functions:

  • Deburring: Quick removal of sharp edges and burrs from laser, plasma, punching, and flame-cut parts.

  • Slag & Dross Removal: Removes heavy slag buildup from plasma or oxy-fuel cutting processes.

  • Oxide Layer Removal: Effectively strips oxide skin, ensuring better welding quality and coating adhesion.

  • Edge Rounding: Adds a uniform radius to the part edge, enhancing coating durability and safety.

  • Surface Finishing: Achieves fine finishes like satin or hairline patterns; prepares surfaces for painting or further processing.

  • Graining: Optionally creates decorative line patterns or straight grain finishes on stainless steel panels.
