Bridge-type stone polishing machines
Bridge stone polishing machines feature CNC-controlled moving bridges with single or multi-head configurations for polishing slabs up to 3000 mm in length. They are used in stoneworking facilities to achieve mirror, matte, or textured finishes on granite, marble, porcelain, and quartzite surfaces.

Bridge polishing machines deliver high-efficiency, automated surface finishing for large-format stone slabs. Their rigid gantry structure and CNC precision ensure consistent pressure distribution, eliminating streaks, swirls, and over-polishing. Models like WANLONG QDM-900, QDM-1200, and QDM-1800 feature water-cooling systems, variable spindle speeds (up to 560 RPM), and programmable path control for optimal surface quality.
These machines are ideal for high-volume production of countertops, cladding panels, stair treads, and architectural elements where visual consistency and finish uniformity are critical. Sequential diamond pad changes—from coarse to fine grit—are fully automated, enabling a complete polishing cycle without manual intervention.
KNAVI GROUP supplies bridge polishers directly from WANLONG (China). All units come with full English documentation, up to 2 years of warranty, operator training, and optional on-site commissioning worldwide.
