400mm Wet Wide Belt Sander Sanding Machine for Laser-Cut and Stamped Sheet Metal (Model: RR5240)

The RR5240 400mm Wet Wide Belt Sander is an industrial-grade metal surface treatment machine specifically designed for laser-cut and stamped sheet metal parts. This machine efficiently performs deburring, deslagging, oxide removal, surface sanding, and finishing, ensuring high precision and uniformity across various metal materials.

With a maximum working width of 400mm, it is ideal for processing medium-sized metal sheets and components, providing a consistent surface finish required in automotive, aerospace, electronics, and general metal fabrication industries. The wet grinding system significantly reduces dust and heat, preventing material deformation and enhancing workpiece quality.
