RSPM-500 Automatic Single Head Bridge Polishing Machine: Precision Grinding Redefined

Elevate Your Stone Slab Finishing with Automated PLC Control

The Ruisheng RSPM-500 Automatic Single Head Bridge Polishing Machine is engineered for high-throughput stone processing factories that refuse to compromise on surface finish. Combining the stability of a robust bridge-style platform with the intelligence of a PLC control system, this machine delivers consistent, factory-grade polishing for granite and marble slabs with minimal manual intervention.

Key Features & Technological Advantages

Intelligent PLC Control System:

Unlike conventional machines, the RSPM-500 features a PLC (Programmable Logic Controller)​ combined with manual programming. This allows operators to easily set grinding parameters, store repeatable processing paths, and ensure uniform polishing results across every single slab, eliminating human error.

High-Power Grinding Capability:

Equipped with a 15 kW main motor​ driving a substantial 470 mm diameter grinding head, this machine possesses the necessary torque and cutting surface to handle tough natural stones efficiently, removing imperfections and achieving a flawless, glossy finish.

Generous Processing Dimensions:

With a massive 3200 x 2000 mm​ worktable and an X-axis travel of 2100 mm, the RSPM-500 can accommodate large-format slabs with ease. The 150 mm Z-axis stroke​ provides ample depth control for various surface leveling and bullnosing applications.

Robust Industrial Construction:

Built with a heavy-duty steel frame, this machine weighs 21.6 kW​ in total power consumption (indicating a highly efficient and powerful build) and measures 5800 x 3300 x 2450 mm. Its solid construction ensures zero vibration during high-speed rotation (up to 2900 rpm), which is critical for precision polishing.
