MIT researchers collaborating with Scholl Concepts have decoded the physics behind nano-engineered foam pads. Laser-etching 50nm grooves onto polyurethane surfaces creates directional abrasive channels, reducing hologram defects by 67%. High-speed cameras capture how these microstructures control compound flow at 2,800 RPM, maintaining optimal lubrication film thickness.

“It’s like constructing microscopic aqueducts for polish particles,” explains project lead Dr. Hiro Tanaka. Commercial applications already emerge, with Rupes’ LHR75E polisher achieving 0.02μm RA surface finishes using these pads. The technology particularly benefits soft Japanese paints, reducing the need for multi-stage corrections.
