How to judge whether the gear rotation of the floor grinder is good or bad? In floor construction, floor grinders are very important floor grinding equipment. After long-term use, they may encounter some failures during operation. Among them, gear rotation is a very important problem. How to judge the floor How good is the gear of the grinder? 1. Listen to the sound, the operating noise of a floor grinder with good processing accuracy can be comparable to that of a belt drive. 2. Look at the selection of materials, high-quality equipment will consider the mechanical heat dissipation performance of mechanical dry grinding, so aluminum alloy materials will be selected. 3. Look at the accuracy of the ground grinding machine's rotation and fit clearance, and test the fit clearance by turning the grinding disc by hand. 4. The durability of the floor grinder has a lot to do with the cabinet design. After determining the cabinet material, look at the weight of the mechanical grinding head.

How to choose and use grinding pads in floor treatment? Grinding pads are one of the tools in the floor refurbishment treatment. The suitable grinding pads for floor treatment of different materials are also different. Xingyi will introduce you to the factors that affect the selection of grinding pads. Flatness of the ground Manual troweling and leveling of the ground or the old ground that is loose and severely damaged. It is necessary to level or remove the loose surface layer. You need to use a high-power grinder. Choose a grinding disc with strong grinding power and suitable for leveling, such as a concrete diamond grinding disc. The hardness of the ground The concrete used in the design and construction of the concrete floor is represented by a number, which is what we usually talk about C20, C25, C30, etc. Under normal circumstances, the higher the number, the better the strength and hardness of the concrete, but due to various Due to the influence of factors, the marking of concrete and the hardness of the ground are often not corresponding. The hardness of the concrete floor is usually expressed by Mohs' hardness. The hardness of the concrete floor is usually between 3-5. On the construction site, we can use some substitutes instead of the Mohs hardness tester to understand the hardness of the floor: the hardness of the dents and the scratches that can be drawn with iron nails and keys is less than 5, otherwise The hardness is greater than 5. The quality and speed of the grinder Floor grinding machines are usually divided into small, medium and large types. Generally speaking, the larger the machine, the greater the power, and the higher the efficiency. In actual use, it is not that the larger the machine, the better. Although the grinding efficiency of oversized and overweight grinders is very high, it will often lead to excessive grinding during use. Cost of construction. Experienced workers will adjust the machine speed, moving speed, number of grinding discs and machine counterweight according to the characteristics of the machine to reduce construction costs and improve construction efficiency. Type and size of grinding pads The commonly used abrasives for floor treatment are PCD abrasive pads, metal-based abrasive pads, and resin-based abrasive pads. PCD abrasive pads are used to remove thick coatings on the floor surface, and metal-based abrasive pads are used for floor surface pretreatment and rough grinding. Resin-based grinding pads are used for rough grinding, fine grinding, fine grinding and polishing of the surface. The particle size of the abrasive disc refers to the size of the diamond particles contained in the abrasive tool. The lower the number, the larger the particle size. The above are the 4 factors that affect our choice of polishing pads. I believe everyone has already understood. Then in the future floor treatment, if you are still wondering what kind of polishing pads to choose, you c...

 Happy Mid-Autumn Festival The Mid-autumn festival is approaching. Happy Mid-autumn festival to you. Mid-Autumn Festival, also known as the Moon Festival or Zhongqiu Festival is a popular lunar harvest festival celebrated by Chinese and Vietnamese people. The moon festival is celebrated on August 15 of the lunar calendar. Is one of the most traditional of Chinese holiday.
