Product Introduction

Achieve Mirror Perfection: The RPQ-S20 Single Head Bridge Polisher

Ultimate Surface Finishing for Slabs, Countertops, and Architectural Stone.

In the stone fabrication industry, the final step determines the product's value. Introducing the RPQ-S20 Single Head Bridge Type Polishing Machine​ from Ruisheng-the pinnacle of finishing technology designed for workshops that refuse to compromise on quality. Whether you are processing natural granite, marble, or engineered quartz, this machine delivers a flawless, mirror-like polish efficiently and consistently.

Automatic Single Head Bridge Polisher

1. Industrial Power Meets Precision

The RPQ-S20 is built to handle the most demanding production schedules without sacrificing the fine details.

  • Massive Working Platform:​ With a generous table size of 3200 x 2000 mm, the RPQ-S20 can accommodate large-format slabs with ease, maximizing throughput and minimizing material handling time.
  • High-Pressure Grinding:​ Equipped with a robust 21.6 kW main motor​ driving a Ø470mm grinding head, this machine provides the sheer power needed to remove scratches, restore surfaces, and achieve a high-gloss finish, even on dense hard stones.
  • Precision Control System:​ Operated via an intuitive PLC control panel​ with manual programming capabilities, operators can easily switch between different polishing grits and recipes, ensuring perfect reproducibility batch after batch.

 

2. Versatile 3-Axis Movement for Complex Profiling

Unlike standard table polishers, the bridge-type design offers incredible flexibility for diverse machining needs.

Full 3-Axis Control:

  • X-Axis (2100 mm Stroke):​ Smooth longitudinal movement for covering large slab surfaces.
  • Y-Axis (1500 mm Stroke):​ Transverse movement for precise edge detailing.
  • Z-Axis (320 mm Stroke):​ Vertical adjustment allows for easy switching between different slab thicknesses or applying varying pressure for different finishing stages.
  • Heavy-Duty Construction:​ The machine features a rugged bridge structure (weighing 5000 kg) mounted on durable yellow cast iron bases. This design guarantees absolute stability during high-speed polishing, eliminating vibrations that cause swirl marks or inconsistent finishes.

 

3. Optimized for Workflow Efficiency

We understand that time is money in a busy fabrication shop.

Linear Rail Guidance:​ Precision-engineered linear guides on the X-axis ensure smooth, backlash-free movement of the spindle, extending the life of mechanical components and reducing maintenance needs.

Ergonomic Design:​ The compact overall dimensions (5900 x 3530 x 2430 mm) make efficient use of factory floor space while providing ample clearance around the worktable for loading and unloading materials.

Cooling & Dust Management:​ Standard water-cooling systems (implied by the plumbing and industrial design) keep the grinding head temperature regulated and suppress dust, ensuring a clean and safe working environment.
