Although both grinding discs and angle grinder discs can be used for grinding, they differ in shape, size, and purpose.
1. Material Composition:
Angle Grinding Pads: These are resin abrasives typically reinforced with special fiber fabric, combining a high-toughness fiber reinforcement mesh with a resin binder.
Grinding Discs: These are generally made by embedding fine abrasive grains (such as alumina or silicon carbide) onto a high-strength polyester film using a high-voltage electrostatic field.
2. Applications:
Angle grinder discs: Primarily used for cutting, grinding, rust removal, and polishing metal materials, especially suitable for handling hard-to-reach corners and edges.
Grinding discs: Primarily used for polishing and smoothing material surfaces, providing a bright and fine finish. Suitable for various materials, such as metals, wood, and plastics.
3. Working Method and Characteristics:
Angle grinder discs: Possess high impact strength and toughness, high grinding efficiency, and are easy and safe to use. They can be installed on angle grinders for various grinding operations.
Grinding Discs: Have sharp cutting edges, providing efficient and fine polishing results. Commonly used in home improvement, automotive repair, furniture manufacturing, and other fields.
4. Safety:
Because angle grinder discs may generate fragments or sparks when rotating at high speeds, special safety precautions must be taken when using them, including wearing protective eyewear and gloves.
While caution is also necessary when using polishing discs, the risk is relatively lower.
5. Size and Shape:
Angle grinder discs are typically manufactured according to the model and specifications of the angle grinder, and come in different diameters and thicknesses.
Grinding discs are also available in various sizes and shapes to suit different processing needs.
6. Maintenance and Replacement:
Both angle grinder discs and abrasive grinding discs need to be replaced after a period of use to maintain optimal processing results. The specific replacement cycle depends on factors such as usage frequency and the hardness of the material being processed.
In summary, angle grinder discs and polishing discs differ significantly in material composition, application, working method and characteristics, safety, size and shape, as well as maintenance and replacement. The choice of which tool to use depends on the specific processing requirements and material properties.
