RRRP5440 Wet Wide Belt Sanding Machine

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.


Key Features:

  • 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
