Flexible grinding discs vs. metal grinding discs

The flexible grinding discs are an advanced grinding tool that combines diamond as a grinding material and resin as a bond. This unique formula provides superior polishing performance and versatility. The pad has large abrasive particles visible in its structure, ensuring powerful and efficient material removal. For added usability, the velcro cloth is securely glued to the back of the mat. This allows easy attachment to the grinder without complex fastening methods. It is connected to the grinder through the grinding joint and is bonded with a buckle cloth to ensure stability. The diamond abrasive used in flexible diamond polishing pads is known for its hardness and durability. This enables maximum abrasive power for fast and precise material removal. Whether polishing stone, concrete, ceramic, or glass, this polishing pad delivers superior results, leaving surfaces smooth and flawless.

Advantages of the flexible grinding discs

Reduced risk of scratching:

The resin in pads provides a fixed cushioning effect, making it less likely to scratch the stone during the grinding process. This helps maintain the quality and integrity of the stone surface.

Scratches Repaired Easily:

Using flexible diamond polishing pads can minimize the appearance of hard-to-repair scratches on stone surfaces for a smoother, more perfect finish.

Low requirement for subsequent laps:

The properties of the flexible diamond pad reduce the need for further processing with high quality or specific laps, making the overall polishing process more convenient and cost-effective.

Advantages of metal diamond grinding pucks

Very sharp cutting capabilities: Known for their sharpness, metal diamond pucks are effective at removing material quickly and efficiently.

Powerful cutting ability: The combination of metal and abrasive in the disc provides a powerful cutting force for more efficient grinding and leveling of surfaces.

Level large height differences with ease: Metal diamond pucks are capable of leveling significant height differences in surfaces, making them ideal for projects that require extensive material removal.

The difference between flexible sanding discs and metal grinding discs

Leveling effect: Flexible diamond pads have a better leveling effect than metal grinding pucks. This is because diamond floppy disks are made from a resin composite, which makes them relatively soft and less likely to scratch the surface being ground. Metal abrasive pucks, on the other hand, are more prone to scratches or marks on the surface.

Sharpness: Metal discs generally have higher sharpness than soft diamond discs. Metal discs are designed for cutting hard materials, such as metal or concrete, with a sharpness that removes material more efficiently. Diamond floppies, while still valid, may not have the same sharpness.

Subsequent connection of grinding discs: Flexible diamond pads are generally less demanding when connecting with subsequent grinding discs. This means they can generally be used with a wider range of discs without requiring specific compatibility. Metallic grinding pucks, on the other hand, may place higher demands on the connection to subsequent grinding discs. This may be due to factors such as the type of abrasive material or the specific application.

In general, soft diamond abrasives and metal abrasives have different characteristics and are often used for different purposes. Consider the specific requirements of your project, such as the type of abrasive material, desired surface finish, and desired sharpness, to determine which type of abrasive disc is most suitable.

The selection principles of flexible sanding pads and metal grinding discs can be summarized as follows

Level difference: For general level difference, it is recommended to use the flexible diamond pad. However, for particularly severe level differences, such as differences of more than 1 cm, metal grinding pucks will be more suitable.

Material Considerations: If you are working with soft marble and limestone surfaces, flexible diamond pads are recommended. Metal grinding pucks can be too abrasive and easily remove too much material.

Stone hardness: Flexible diamond pads can solve most of the gap problems in natural stone. However, when dealing with particularly hard stones, it may be more effective to use a metal grinding puck.

Floor Type: If you’re working on terrazzo and concrete floors, metal grinding pucks are recommended. Flexible diamond pads are generally not recommended for use on these surfaces.

When choosing between flexible diamond pads and metal grinding pucks, keep these selection guidelines in mind to ensure the most efficient and suitable tool for your specific project requirements.
