Application Industry

1. Metal processing manufacturing industry: Plays a key role in the entire process of mechanical manufacturing, from rough processing of raw materials, such as removing the surface oxide scale of steel blanks, to fine grinding of semi-finished products, such as improving the surface finish of various shaft parts, and then polishing of finished products, to ensure that metal products meet the design requirements of precision and appearance quality.
2. Automobile repair and maintenance: Aluminum Oxide flap discs are frequently used in automobile repair shops to polish the surrounding areas of damaged paint during car body repair to provide a flat surface for new paint to adhere; to remove rust and burrs from metal parts such as automobile chassis and wheels to ensure vehicle driving safety and neat appearance; in the production of automobile parts, it is also used to polish castings to improve product quality.
3. Building decoration industry: At construction sites, it is used to polish metal door and window frames, stair handrails, etc. to remove processing marks and make them smooth and beautiful; decoration workers also use it to polish and trim the edges of stone countertops and floor tiles to meet the requirements of installation accuracy and aesthetics; in the process of making wooden furniture, the cut surfaces and corners of the wood can be polished to prevent wood thorns from hurting people and improve the texture of the furniture.

Usage

1. Tool adaptation: Select the appropriate electric grinding tool according to the size and type of the Aluminum Oxide flap discs. Generally speaking, a high-power angle grinder is used for large-area rough grinding operations, and its high speed can give full play to the grinding ability of the flap disc; for fine grinding tasks, such as small precision mechanical parts or handicraft processing, a low-speed, high-torque straight grinder should be selected to facilitate precise control and ensure the grinding effect. At the same time, make sure that the tool spindle matches the louver installation hole and is firmly installed.
2. Installation points: Before installation, be sure to shut down the machine and turn off the power, align the flap disc with the tool spindle and gently insert it, and then use the matching wrench to tighten the fixing nut. During the installation process, it is necessary to check by hand or with the help of measuring tools to ensure that the flap disc is installed concentrically to avoid eccentricity causing violent vibration during grinding, which will not only reduce the grinding accuracy, but also may damage the flap disc and the workpiece being ground.
3. Parameter control: Reasonably adjust the tool speed and grinding pressure according to the material hardness of the grinding object and the grinding stage goals. For example, when grinding soft wood or rough grinding, the speed can be increased appropriately and the pressure can be increased to speed up the material removal speed; while when processing hard metal or entering the fine grinding stage, the speed needs to be reduced and the pressure needs to be applied gently to prevent excessive grinding from causing damage to the workpiece surface. At the same time, the grinding effect can be observed in real time and the parameters can be adjusted flexibly.
4. Grinding operation: Hold the power tool firmly with both hands, so that flap disc touches the workpiece surface at a suitable angle (usually 15° - 30°), and move the tool at a constant speed along the established trajectory to ensure that the grinding surface is fully covered without omission. During the grinding process, pay close attention to the temperature and vibration of the tool. If the temperature is too high or the vibration is abnormal, the machine should be stopped immediately for inspection to avoid safety accidents.

Precautions

1. Safety protection in place: When using flap discs, you must wear complete protective equipment. Goggles should be worn throughout the process to prevent debris from grinding from splashing into the eyes and causing eye damage; thick gloves can effectively prevent hand scratches; wearing work clothes can prevent both dust and scratches. If working in a dusty environment, you must also wear a dust mask to protect the respiratory system; at the same time, warning signs should be set up at the grinding site, and unrelated personnel are strictly prohibited from approaching to prevent accidental injuries.
2. Regular inspection and maintenance of equipment: Before each use, carefully check whether the power cord, switch, bearing and other components of the power tool are normal to ensure that there are no safety hazards; after use, clean the dust and debris attached to the tool body in time, and disassemble the tool regularly for maintenance to extend its service life. For flap discs, they should be replaced in time according to the wear condition. Generally, when the sand particles fall off severely and the grinding effect is significantly reduced, that is, when the wear exceeds 1/3, it is recommended to discard and replace with a new one to avoid affecting work efficiency and grinding quality.
3. Standardize the operating procedures: It is strictly forbidden to use brown corundum louver blades in flammable and explosive environments, such as oil depots, chemical workshops, warehouses for storing flammable materials, etc.; during the grinding process, the louver blades must never be pointed towards yourself, others or flammable objects to prevent loss of control and injury to people; if the tool has abnormal vibration, overheating, odor, etc., it must be shut down and powered off immediately to check the source of the fault and restart it after repair to ensure safe operation.
