400mm Wet Wide Belt Sander – RRRP5440
Four-Station Deburring, Edge Rounding & Polishing Machine with Three Sanding Belts & Nylon Fiber Wheel
The RRRP5440 400mm Wet Wide Belt Sander is an advanced, high-performance metal finishing solution designed for deburring, edge rounding, and surface polishing of laser-cut and stamped sheet metal. Featuring four working stations, including three sanding belts and one Nylon Fiber Wheel Flap Polishing Wheel, this machine ensures sequential processing for superior surface quality.
This model is available in two configurations:
Magnetic Conveyor Worktable – Provides strong hold-down for small and thin metal parts, ensuring precise processing.
Non-Magnetic Conveyor Worktable – Offers versatility for standard sheet metal processing without magnetic hold.
By utilizing wet sanding technology, the RRRP5440 effectively prevents heat buildup, minimizes airborne dust, and extends abrasive belt lifespan, making it ideal for stainless steel, aluminum, and carbon steel applications.
Features & Benefits
Four-Station Processing:
Station 1, 2 & 3: Three abrasive belts remove rough edges, burrs, and surface irregularities step by step.
Station 4: Nylon Fiber Wheel Flap Polishing Wheel refines the surface for a smooth, polished finish.
Efficient Deburring: Eliminates sharp burrs and rough edges from laser-cut, plasma-cut, and stamped metal parts.
Superior Edge Rounding: Produces uniformly rounded edges, improving safety, coating adhesion, and overall part quality.
Nylon Fiber Polishing Wheel: Delivers consistent fine finishing, creating a smooth, satin-like surface texture.
Wet Sanding Technology: Prevents overheating, reduces airborne dust, and improves abrasive belt longevity.
Versatile Material Compatibility: Suitable for stainless steel, carbon steel, aluminum, and non-ferrous metals.
Adjustable Feed Rate: Allows customized processing for different thicknesses and material types.
Magnetic vs. Non-Magnetic Conveyor Options:
Magnetic Conveyor: Ensures firm grip on thin metal parts, preventing movement during processing.
Non-Magnetic Conveyor: Offers greater flexibility for standard sheet metal finishing applications.
Compact & Robust Design: Built for industrial durability and long-term reliability.
