A floor grinding machine is an industrial piece of equipment used for grinding, polishing, and leveling floors. It is mainly used for the construction and renovation of concrete, epoxy, and stone floors. During operation, it is necessary to control the progressive grinding grit, move the machine smoothly, and take safety precautions to achieve a smooth and clean grinding effect.
I. Pre-construction Preparation: Clean the work area of debris and oil stains;check the motor, grinding disc, and cable of the grinding machine for damage; install the appropriate grit of grinding discs according to the floor hardness and grinding requirements (50-100 grit is preferred for coarse grinding).
II. Adjustment and Coarse Grinding
Connect the power supply and adjust the grinding depth of the grinder (0.5-1mm is recommended for initial adjustment). After starting the machine, test grind a corner first to ensure there are no abnormalities before proceeding to a larger area.
III. Gradual Fine Grinding
After coarse grinding, clean the grinding dust from the floor and replace with a higher grit grinding disc (increasing in the order of 150 grit → 300 grit → 500 grit). Repeat the grinding operation, cleaning the floor thoroughly after each disc change. During the fine grinding stage, the grinding depth can be appropriately reduced (0.2-0.5mm) to ensure the floor smoothness gradually increases until the desired flatness and fineness are achieved.
IV. Cleaning and Finishing Steps
After final grinding, turn off the power, disassemble and clean the grinding discs; use a vacuum cleaner or high-pressure washer to thoroughly remove dust from the floor. If subsequent curing or polishing is required, allow the floor to dry after cleaning; tidy up the machines and tools, disconnect the power, and perform equipment maintenance.
