Industrial-Grade Concrete Floor Grinding – Reinvented by XINGYI GX550
Built for High Precision, Low Maintenance & Powerful Results

The XINGYI GX550 is engineered for flooring professionals and contractors who need a high-precision, high-coverage grinding and polishing machine capable of delivering consistent performance on large industrial and commercial surfaces. Equipped with a three-head planetary system (230 mm per head) and a 550 mm grinding path, it offers fast surface coverage and outstanding productivity across medium to large job sites.

Its advanced mechanical design ensures smoother rotation, reduced vibration, and improved stability — especially with the latest Q/X system, which outperforms older models in weight balance, structural rigidity, and adjustable grinding pressure. This provides superior control over different concrete conditions, coatings, and surface hardness levels.

Powered by a 5.5 kW / 4 HP – 220V industrial motor, the GX550 delivers steady torque under load, while its broad speed range of 350 to 1500 RPM supports everything from heavy material removal and coating stripping to fine surface polishing for epoxy preparation or industrial finishing. The progressive speed control enhances heat management, extending the lifespan of internal components.

The machine’s enhanced cooling fan and optimized airflow keep temperatures low during extended operation, ensuring reliability for contractors working on floor rehabilitation, warehouse resurfacing, industrial maintenance, and concrete finishing.

Key Features & Benefits:

• Powerful Performance: 4kW / 5.5HP motor with a 5.5kW inverter delivers stable grinding power using 220V single-phase electricity.
• High Coverage Efficiency: 3 rotating heads (230mm × 3) provide a 550mm working width for fast, uniform surface coverage.
• Adjustable Pressure Control: Movable iron weights allow precise customization of grinding pressure to suit various applications.
