How to Choose the Right Diamond Tool for Grinding and Polishing

How to Choose the Right Diamond Tool for Grinding and Polishing

Concrete floors, particularly polished concrete floors, are quickly becoming the preferred choice for contractors and customers everywhere, from industrial facilities to residential developments and high-end corporate headquarters. Concrete floors are durable, long-lasting, environmentally friendly, reflect light beautifully, and can look like natural stonework, in addition to lowering maintenance costs.

To transform an old concrete floor, the difficult task of preparing it for a new application must first be completed. Cleaning and sanitising are essential, but so is removing any residues or coatings that may interfere with the successful execution of a concrete polishing job.

Depending on the type, the hardness of the concrete, the desired finish, and the size of the surface, diamond grinding can remove virtually any coating, epoxy, glue, or mastic. Between the grinding machine and the concrete surface, diamond tooling is the true workhorse.

It is critical to understand how to select the type of diamond tooling that will be most effective for the substrate as well as the desired end result.

In this article, we’ll go over how to choose diamond tools for grinding and polishing concrete, as well as how to use them.

Diamond Grinding 101

By attaching a diamond grinding tool to a grinding machine, you can chip away at hard surface materials like concrete, granite, and marble. Diamonds have a hardness rating of 10 on the Mohs scale. Diamonds are thus the hardest materials on the planet.

However, the diamond grit that you select can have an impact on the surface area to which you apply them. It is critical to select a diamond grinding tool with the proper segment bond.

To begin, make sure you have the correct size diamond tool for your project. Grinding concrete may necessitate larger tooling than removing a small amount of paint.

Diamond tools with smaller surface areas are generally considered more aggressive. As a result, after grinding, these tools leave more scratching on surfaces.

Larger diamond tools are likely to produce the smoothest finish. Make sure you understand your resurfacing plan before choosing the size of your concrete grinding tool.

What is a bond?

The bond holds diamond crystals in the diamond tool as they are ground to the slab surface using an abrasive grinding process. Diamonds become visible as the bond deteriorates over time.

On hard surfaces, grinding tools with soft bonds work well. The bond will eventually wear away, exposing the sharp diamond pieces and allowing them to do their job.

If you’re working on a soft or gritty surface, you’ll need a stronger bond. As a result, the diamond does not deteriorate as quickly.

What is a grit?

Finally, you must assess the grit of the diamond, which indicates whether it is coarse or fine. For a concrete floor grinder working on a coarse surface, a diamond with a coarser grit (30 to 40) is best. If you want to polish your surface, you’ll need a finer grit. Smoother surfaces are possible if the grit is greater than 40. For a longer period of time, you will need to use higher-grit grinding cup wheels. You should consider your grit levels when attempting to balance your end result with your productivity.
