Koenig FinishForce BW-630 (WetLine) – Compact Wet Widebelt Sanding for Metal Finishing The Koenig FinishForce BW630 (WetLine) is a compact wide belt sanding and linishing machine designed for precision finishing of metals, including aluminum. With a 630 mm processing width, it’s ideal for small to medium-sized parts where consistency and surface quality matter most. This machine incorporates a water sanding frame inside the sanding chamber, enabling wet sanding of aluminum, stainless steel, magnesium alloy, copper plate, and man-made stone plates in a single pass. Unlike traditional dry sanding, the wet process reduces heat build-up, avoids dust collection requirements, and extends the lifespan of abrasives while producing smooth, high-quality finishes. The fully enclosed sanding enclosure ensures water does not spray outside, while all bearings and electrical parts are sealed and waterproof — prolonging machine life and guaranteeing safe, reliable operation. For applications where wet sanding isn’t required and precision finishing of ferrous metals is the priority, the FinishForce B-Series offers a versatile range of sizes and configurations. For workflows that also require edge rounding alongside wide belt finishing, the Koenig FinishForce PRO – BR-Series delivers consistent, high-quality results with its 360° flap brush
