how to grind concrete？ Slow down the sanding speed Because the grinder has a variable speed function, it sometimes lifts and skips the surface during operation. If the machine runs too fast, it will reduce the construction efficiency. Although running with a higher speed setting speeds up the polishing of the floor, the result is often an uneven performance, leading to more rework and lower satisfaction. Increase concrete cushion If you find a lot of sand and machine-generated debris when polishing the concrete floor, the most likely situation is that the concrete base layer is too thin and the concrete base is ground. Large grit at the bottom of the concrete will wear expensive diamond grinders, and it is also very disadvantageous for vacuum hoses and filters. Therefore, it is necessary to increase the concrete floor cushion before polishing to increase the thickness of the floor. Use suitable lubricating oil When using a scraper tool on a sander or a cemented carbide tool on a ripper, you need to spray a mild lubricant on the tool. This process will help the tool to keep cool, and will reduce the amount of material accumulation on the tool. This process is very effective in protecting the sand box chassis on the ripper. When cleaning polished floors or coatings, try not to use cleaning compounds. Detergents are very popular, because dirt and dust are sealed in oil, and the solids remain dry, making cleaning easier, but this can impair the functionality of the sanding machine.
