Types and Uses

Importance in stone processing

The primary use of resin edge grinding wheels is to smooth the edges of stone, which tend to become rough and uneven after the initial cut. Using these pads, operators can achieve a polished edge that is not only aesthetically pleasing but also improves the overall durability of the stone. For applications where the stone will be visible, such as countertops, flooring, and decorative elements, the smoothness achieved through this process is essential.

In addition to edge polishing, resin edge grinding wheels are versatile and can be used for automated grinding and polishing of irregular surfaces. This includes the complex patterns, curves and steps commonly found in a variety of natural and artificial stones. The adaptability of these grinding pads makes them highly valuable in both commercial and residential stone work.

Specifications and dimensions

Resin edge grinding wheels are typically available in 5" and 6" sizes to suit a wide range of grinders. Working layer thickness is typically between 5 and 10mm, allowing for efficient material removal whilst maintaining control over the polishing process. These pads are often fitted with a snail-back connection for easy installation onto the grinder.

Resin edge grinding wheels are available in a wide range of grit sizes, from 50 to 3000. This wide range of grits allows users to select the right grit for their specific polishing needs. Coarse grit (lower grit) is suitable for initial grinding and material removal, while fine grit (higher grit) is used to achieve a high gloss finish.

Supplementary tools

When using a resin edged wheel, it is often used in conjunction with a metal edged wheel for rough grinding. This combination allows for more efficient polishing, as the metal wheel can quickly remove larger imperfections before the resin pad is used to smooth the surface. This two-step operation not only ensures a polished edge for the stone, but also ensures that it is structurally sound.

Performance Characteristics

1. Excellent finishing effect

One of the highlights of resin-edge grinding wheels is their excellent dressing effect. By combining high-temperature resistant resin with diamond abrasives, these grinding wheels are effective in polishing and finishing. The self-sharpening nature of resin grinding wheels causes the abrasive particles to break down into smaller pieces during use, thereby continuously exposing new cutting edges. This process ensures that the grinding wheel maintains stable processing efficiency throughout its service life.

In addition, the elastic cushioning effect of resin polishing pads helps prevent over-abrasion, especially for mirror polishing of brittle materials such as marble and quartz. These polishing pads can achieve surface roughness of Ra 0.2 μm or less, making them ideal for applications where perfect polishing is required.

2. Good flexibility

The resin edged grinding wheel is designed with flexibility in mind, making it suitable for complex polishing surfaces. This feature is particularly useful when working with bevelled edges and curved surfaces such as countertops. Its ability to adapt to a variety of shapes and contours makes the polishing process more comprehensive and efficient, ensuring that all areas of the stone are treated evenly.

3. Long service life

Another major advantage of resin bond edge polishing pads is their long service life. These polishing pads have extremely high grinding sharpness and durability, thanks to the optimization of abrasive concentration (usually controlled in the range of 15% to 25%) and the careful selection of diamond particle size (ranging from 80# to 3000#). As a result, the service life of a single resin bond grinding wheel can reach 120 to 150 hours, significantly reducing the total cost by up to 40% compared to traditional tools.

This long life makes the resin edge grinding wheels particularly suitable for automated grinding and polishing of a wide range of natural and artificial stone surfaces, including lines, curves, steps and other irregular shapes.

4. Wide applicability

Resin bond edge polishing pads are versatile and compatible with a wide range of grinding equipment. They can be used with double-sided grinders, straight edge grinders, and four-sided grinders, making them a valuable addition to any stone processing workshop. This wide range of applicability ensures that manufacturers can use these polishing pads on different processes and equipment, thereby improving the efficiency of their operations.
