The XINGYI GX510 floor grinder was recently put to the test during a hands-on demonstration in Japan, giving local flooring professionals the opportunity to experience its grinding performance and operation firsthand. Hosted by Kawamura Kogyo Co., Ltd., the event brought together contractors and industry professionals from Hiroshima, Okayama, and Osaka for live equipment demonstrations and technical exchange. Hands-On Experience with the GX510 During the demonstration, participants operated the GX510 concrete floor grinder in real working conditions and experienced its grinding performance, efficiency, maneuverability, and ease of operation. The hands-on format allowed contractors to go beyond machine specifications and see how the GX510 performs in practical concrete grinding and surface preparation applications. Connecting with Flooring Professionals in Japan Live demonstrations are also an important way to understand local jobsite needs and gather direct feedback from flooring professionals. XINGYI will continue to work closely with contractors and partners worldwide, bringing professional floor grinding equipment and practical surface preparation solutions to more markets. A special thanks to Kawamura Kogyo Co., Ltd. and everyone who joined the demonstration in Japan.

Dry concrete grinding can generate large amounts of fine dust. Without effective dust extraction, dust can spread across the jobsite, reduce visibility, increase cleanup time, and affect working conditions. A properly matched industrial dust extractor helps collect dust directly during grinding and keeps the floor preparation process cleaner and more efficient. Why Dust Extraction Matters During Grinding Dust control is more than keeping the jobsite clean. During concrete grinding and floor preparation, effective dust extraction helps: Capture fine dust close to the source Reduce airborne dust Keep the working surface cleaner Reduce cleanup after grinding Support more continuous grinding operations The key is matching the dust extractor to the grinder and the amount of dust generated. Built for Floor Grinding Applications The IVC-F65L Industrial Dust Extractor is designed for medium-sized floor preparation projects and can be used with grinding equipment for concrete, epoxy floors, terrazzo, and natural stone applications. It features a 2.2 kW / 3 HP motor with an airflow rate of 358 m³/h, providing the suction needed for professional floor grinding applications. A 65 L dust collection box provides practical capacity for jobsite use, while the detachable design makes collected dust easier to remove and dispose of. Filtration for Fine Dust Fine concrete dust requires effective filtration. The IVC-F65L uses an H-grade filter, which the product specification states can filter 99.9% of 0.3 μm particles. Combined with its AMETEK motor, the system is designed to provide stable dust collection during floor preparation work. Cleaner Grinding Starts at the Source The best way to manage grinding dust is to collect it where it is generated. By pairing the right floor grinder and industrial dust extractor, contractors can create a cleaner workflow, reduce post-grinding cleanup, and improve overall jobsite efficiency. For medium-sized floor grinding and surface preparation projects, the IVC-F65L provides a practical balance of suction, filtration, dust capacity, and mobility.

Proper concrete surface preparation is essential before applying epoxy, polyurethane, or other floor coatings. Oil, dust, old coatings, adhesives, and weak concrete can reduce adhesion and lead to peeling or coating failure. A properly prepared concrete floor should be clean, dry, sound, and have the correct surface profile. 1. Inspect the Concrete Surface Before starting, check the floor for: Old coatings or adhesives Oil and surface contamination Cracks or damaged concrete Uneven areas Moisture issues The condition of the floor will determine the best concrete floor preparation equipment for the job. 2. Choose the Right Surface Preparation Method Concrete Grinding Concrete grinding is one of the most common methods for epoxy floor preparation. A floor grinder with the correct diamond tooling can remove coatings, adhesives, and surface imperfections while creating a suitable surface for the next flooring system. For general floor preparation and coating removal, the XINGYI GX510 Planetary Concrete Floor Grinder is designed for demanding surface preparation applications. For edges, corners, and tight spaces that larger grinders cannot easily reach, the XINGYI GX250 Edge Concrete Grinder provides a compact solution. Shot Blasting For larger areas or projects requiring a more defined Concrete Surface Profile (CSP), a concrete shot blaster can efficiently remove surface contaminants while profiling the concrete. XINGYI offers dedicated concrete shot blasting equipment for professional surface preparation and coating removal applications. Scarifying For thick coatings, damaged concrete, or more aggressive material removal, a concrete floor scarifier may be the better choice. Scarifying removes material more aggressively than standard grinding and can create a deeper surface profile when required. 3. Achieve the Correct Concrete Surface Profile Removing the existing coating is only part of the process. The prepared concrete must also meet the CSP requirements specified by the coating manufacturer. A surface that is too smooth may reduce adhesion, while excessive profiling can increase coating consumption. 4. Control Dust and Clean the Floor Dry concrete grinding can generate significant dust. Using a properly matched industrial vacuum cleaner or dust extractor helps control airborne dust and keeps the prepared surface cleaner. XINGYI currently offers industrial vacuum solutions designed to work with floor grinding equipment. Before applying epoxy or another coating, make sure the concrete is: Clean. Dry. Sound. Properly profiled. Good coating performance starts with good surface preparation.
