RRRP5440
Heavy-Duty Metal Belt Sander for Precision Deburring and Finishing
The RRRP5440 is a high-performance wet wide belt sanding machine engineered for deburring, edge rounding, oxide removal, and surface finishing of sheet metal and metal parts. With a working width of 400mm, it is ideal for small to medium-sized metal components from laser cutting, punching, and shearing processes.
Its wet grinding system minimizes dust, cools the workpiece during processing, and delivers consistent surface results with extended abrasive belt life.
Model: RRRP5440
Working Width: 400mm
Sanding Stations: 2 or 3 configurable stations
Wet Operation: Water-based cooling and cleaning system reduces heat, improves finish, and protects operator health
Vacuum or Magnetic Worktable (optional): Secures thin or small parts
Heavy-duty structure: Industrial design for long-lasting reliability
Independent Operation: Each sanding head operates separately for different processing stages

Swing Motor Power | 1.5 kW |
Machine Dimensions | 2400 × 1500 × 1800 mm (L×W×H) |
Machine Weight | Approx. 1500 kg |
Belt Size | 1520mm × 400mm |
Deburring after laser cutting, punching, flame or plasma cutting
Edge rounding for safer handling and better paint adhesion
Oxide layer removal from thermal cutting
Surface brushing for stainless steel, aluminum, or mild steel
Pre-treatment for powder coating or welding
Wet processing for higher quality finish and safety
Multiple abrasive heads for sequential grinding/polishing in one pass
Consistent surface treatment – superior to manual sanding
Efficient dust and heat control – prolongs tool life
Low operational cost with high output
