RRRP5440
The RRRP5440 Wet Wide Belt Sander is a heavy-duty industrial sanding machine built for precision metal surface processing. Equipped with four working stations—including three sanding heads and one brush head—this machine provides comprehensive deburring, oxide removal, edge rounding, and fine surface finishing in a single pass.
Unlike magnetic conveyor models, the RRRP5440 uses a standard non-magnetic conveyor bed, allowing it to handle a broader range of materials, including non-ferrous metals like aluminum and copper, as well as stainless steel and mild steel. Its wet sanding technology reduces heat buildup, prevents material distortion, enhances abrasive life, and ensures superior surface finishes with minimal dust emissions.
Three abrasive belt heads: Handle heavy burr removal, oxide layer removal, and smooth surface graining.
One brush head: Designed for uniform edge rounding, creating smooth, safe edges without compromising material thickness.
One-pass multi-process solution, saving labor time and improving consistency.
Water-cooled sanding heads effectively manage heat.
Minimizes material deformation, discoloration, and reduces the risk of workpiece burning.
Enhances safety by reducing dust pollution during the sanding process.
Without magnetic restrictions, the RRRP5440 is suitable for ferrous and non-ferrous metals alike.
Ideal for stainless steel, carbon steel, aluminum, brass, copper, and various alloys.
User-friendly programmable interface with adjustable settings for belt speed, feed rate, and brush rotation.
Easy recipe management allows operators to save preferred parameters for recurring jobs.
Heavy-duty industrial frame, precision assembly, and high-quality components ensure long service life and continuous operation.
Reduced machine vibration guarantees stable sanding results.
