Adding water or other coolants during the grinding process helps dissipate heat and improve the performance of the diamond wheel. This practice not only protects the grinding wheel, but also ensures a smoother surface for the tile.

Resin Grinding Disc

Resin abrasive discs are essential tools in the tile and stone industry, specifically designed to grind and polish softer tile surfaces. Made primarily from man-made synthetic materials, these discs offer unique benefits and properties for a variety of applications.

1. Composition and structure

• Crafting Materials: Resin grinding wheels are made of a combination of abrasives and a resin binder. The resin acts as a matrix to bind the abrasive particles together, providing flexibility and adaptability during the grinding process. This composition enables the grinding wheel to effectively grind and polish softer materials, such as tiles and softer stones.

• Design Features: Grinding wheels come in a variety of shapes and sizes, including flat discs and cup designs. The specific design affects the performance of the wheel, including its ability to reach tight corners and uneven surfaces.

2. Cutting mechanism

The cutting action of the resin-bonded grinding wheel is achieved primarily through the friction created between the grinding wheel and the tile surface. As the grinding wheel rotates, the abrasive particles embedded in the resin matrix come into contact with the workpiece, effectively grinding away the material. The heat generated in this process softens the resin, which reduces the hardness of the grinding wheel and enhances its ability to adhere to the surface being machined.

• Material Removal: The combination of abrasive action and softening resin allows for efficient material removal, resulting in a smooth and polished finish on softer tile surfaces.

• Versatility: Resin grinding discs can be used for both grinding and polishing tasks, making them a versatile choice for a variety of applications.

3. Advantages of resin grinding wheel

• Smooth Surface: One of the main advantages of resin grinding wheels is their ability to produce a high-quality, smooth surface on softer materials. The flexibility of the resin allows the wheel to conform to the contours of the surface, producing a polished look.

• Reduce the Risk of Damage: Resin discs are less likely to damage softer tile surfaces than harder abrasive discs. The softer composition of resin discs helps prevent chipping and scratching, making them ideal for delicate materials.

• Easy to Use: Resin discs are generally easy to use and can be used with standard grinders. Their lightweight design and flexibility make them easy to use, even for those with little experience in grinding and polishing.

Limit

• Wear Resistance: A significant disadvantage of resin bonded grinding wheels is that they are relatively less wear resistant than other types of grinding wheels, such as diamond or metal bonded wheels. Resins will wear out more quickly, especially when used on harder materials or in high-volume applications.

• Frequent Changes: Because resin-bonded grinding wheels have a limited lifespan, they may need to be replaced more frequently than other types of grinding wheels. Users should be prepared for this maintenance, especially in environments where grinding and polishing tasks are often performed.

4. Best Practices

To achieve the best results and extend the life of your resin grinding disc, it is critical to control grinding pressure and speed. Too much pressure will cause rapid wear and overheating, while too high a speed may cause premature degradation of the resin.

• Using Coolant: In some cases, using a coolant during the grinding process can help control heat generation and extend the life of the resin disc. The coolant reduces friction and prevents overheating, ensuring consistent performance.

• Regular Inspection and Replacement: Due to the wear-prone nature of resin grinding discs, it is important to regularly inspect them for signs of wear or damage. Replacing worn grinding discs promptly will help maintain the quality of the grinding and polishing process.
