Automatic Profiling Machine for Granite/Marble
RS-G/16C/20C/25C & RS-M/16C/20C Series
High-Efficiency Continuous Polishing Line for Stone Slabs
The Ruisheng Automatic Profiling Machine is engineered for stone factories demanding high-volume, mirror-finish polishing for granite and marble slabs. Available in specialized configurations for granite (RS-G series) and marble (RS-M series), this heavy-duty polishing line combines massive grinding power with continuous automated feeding. With up to 25 customizable polishing heads and a robust 15kW motor per head (marble version), it delivers unparalleled surface finishing efficiency.

Key Features & Benefits
1. Specialized Granite & Marble Configurations
Choose the perfect polishing line for your material:
RS-G Series (Granite): Equipped with 7.5kW grinding head motors, optimized for the hard density of granite. Models include 16, 20, or 25 heads (RS-G-16C/20C/25C).
RS-M Series (Marble): Features heavy-duty 15kW grinding head motors for aggressive material removal and high-gloss finishing on softer marble. Models include 16 or 20 heads (RS-M-16C/20C).
2. Massive Grinding Power & Capacity
The machine dominates large-format slabs with a useful working width of up to 2100mm and thickness range of 10-60mm. The RS-M-20C boasts a massive 311kW total power, ensuring zero vibration and maximum material yield even at full load.
3. Continuous Automatic Feeding
Features a high-efficiency conveyor belt system. The Granite series operates at 0.8-2.5 m/min, while the Marble series reaches speeds up to 3.5 m/min, enabling continuous, unmanned production line workflow.
4. Fully Customizable Polishing Heads
The number of grinding/polishing heads can be customized according to customer requirements. This flexibility allows factories to balance initial investment with specific production output needs.
5. Heavy-Duty Industrial Frame
Built for 24/7 industrial use, the machine features an extra-long, stable frame (up to 14 meters for the RS-M-20C) and an efficient water cooling system (up to 30 m³/h) to keep abrasives and slabs cool.
