Xingyi Concrete Floor Grinder, 20HP, 815mm Working Width - GX858

Self Propelled Floor Grinder 32"

The Xingyi GX858 Concrete Floor Grinder is an industrial-grade surface preparation machine engineered specifically for high-efficiency concrete profiling, grinding, and polishing projects. Driven by a high-torque 15 kW (20 HP) WEG electrical powertrain and custom-tuned inverter technology, this robust 566 kg machine operates powerfully on a 380 V to 480 V three-phase power supply to handle intense, continuous commercial workloads without faltering. It features an expansive 815 mm (32-inch) working width utilizing a four-head planetary configuration with 278 mm counter-rotating grinding discs. This advanced setup delivers precisely controlled variable speeds ranging from 350 to 1950 RPM, guaranteeing flawless scratch uniformity across extremely diverse and challenging slab conditions.

To actively optimize daily production on large-scale jobsites, the machine transitions seamlessly between a self-propelled mode and an intelligent remote control system that responds with millisecond accuracy, removing localized handle vibrations and cutting operator fatigue entirely. A standout design element is its 2-position adjustable counterweight iron mechanism, allowing operators to easily shift the physical weight distribution forward or backward to fine-tune the grinding head down-pressure up to an impressive 400 kg based on floor hardness. Operating effortlessly at a walking speed of up to 20 m/min, the GX858 utilizes a specialized S-type grinding path execution to maximize cross-running force, while an integrated 30 Litres water tank completely supports dust-free wet cutting alongside its standard dry extraction capabilities.

Key Features & Benefits:

• Massive 815 mm Grinding Width: The expansive 815 mm (32-inch) working width allows operators to cover incredibly large commercial surface areas quickly, maximizing daily production output while maintaining strict leveling tolerances.

• Advanced Self-Propelled Drive System: Equipped with an intelligent motorized drive mechanism that physically propels the machine forward, drastically reducing operator fatigue during extensive grinding and polishing operations.

• High-Torque 20 HP (15 kW) Powertrain: Powered by a high-performance, industrial WEG powertrain engineered to tackle the most demanding floor preparation tasks without bogging down under immense surface friction.

• Robust Planetary Gear Drive: Features a highly efficient gear-driven transmission system that ensures skip-free torque delivery directly to the floor, permanently eliminating the slippage and maintenance issues associated with standard belt drives.

• Automated Motion Consistency: Integrates advanced digital drive control that establishes absolute, flawless scratch uniformity across the slab, effectively cutting out operator mistakes and ensuring a perfect polish every single time.

• Versatile Floor Applications: Perfectly engineered and adapted to seamlessly process an incredibly wide range of demanding commercial substrates, including raw concrete, terrazzo overlays, and premium natural stone flooring.

• Intuitive Centralized Controls: Features a highly user-friendly, centralized control panel designed for simple, straightforward operation, allowing for rapid parameter adjustments on the fly without navigating complex digital menus.

• Massive Structural Grinding Pressure: Delivers high-impact down-pressure suited for aggressive coating removal and precision profiling, structurally stabilized by its impressive 566 kg total operating weight.

• 4-Head Planetary Grinding Configuration: Utilizes four planetary counter-rotating heads measuring 278 mm each to deliver a perfectly balanced, cross-hatched scratch pattern that leaves the surface uniformly prepped.

• Precision Variable Speed Control (350–1950 RPM): Features a sophisticated variable frequency drive allowing the operator to adjust rotational head speeds perfectly between 350 and 1950 RPM for both aggressive grinding and delicate resin polishing.

• Dual Wet & Dry Grinding Capability: Performs seamlessly across both dry dust-extracted environments and wet cutting applications, supported by a generous 30 Litres onboard water tank explicitly dedicated to suppressing dust.

• Rugged Industrial Steel Chassis: Constructed utilizing an all-steel frame crafted explicitly to withstand demanding, harsh job site conditions over years of continuous commercial service.

• Adjustable Counterweight Iron System: Built with a modular 2-position weighted chassis, allowing operators to shift iron blocks forward or backward to instantly change head down-pressure up to 400 kg to match varying concrete hardness levels.
