Basic Grinding Equipment Selection For grinding floor tiles, handheld floor grinders are a common tool. These machines typically weigh 3-5 kg and are equipped with diamond grinding discs to handle glazed tiles, vitrified tiles, and other materials. It is recommended to start with a coarse grinding disc (30-50 grit) and gradually switch to a finer disc (150-300 grit) to improve efficiency and ensure a smooth surface. Pay attention to controlling the machine's tilt angle, keeping it within 15° to avoid edge chipping.
Large Area Floor Treatment Solutions For work areas exceeding 10 square meters, a self-propelled floor grinder is recommended. These machines can achieve a working efficiency of 20-40 square meters per hour and are equipped with a dust extraction port to reduce dust pollution. Dual-disc models are suitable for floors with poor flatness, while single-disc models are more suitable for fine grinding. When using a grinder, it is recommended to use a crisscross pattern to ensure a grinding uniformity error of less than 1 mm/2 meters.
Specialty Grinding Techniques: Areas such as wall edges and column bases require specialized corner grinders, characterized by a body thickness of less than 10 cm. When used with a shaped grinding head, it can handle 90° inside corners, while models with a flexible shaft can tackle complex areas such as around pipes. It is recommended to grind the corners first, then the main body area, and finally use a polishing pad to finish the entire surface for a seamless transition.
