Hard diamond polishing abrasive tools are used when processing soft materials, and soft diamond abrasive tools are used on the contrary, but soft abrasive tools are also used when grinding extremely soft and tough materials.

When grinding, the contact area between the workpiece and the polishing tool is large, so the hardness of the polishing pad should be lower. Form grinding, in order to ensure the accuracy of the geometry of the workpiece, the hardness can be appropriately selected higher.

In the grinding process, the speed of the abrasive tool is high, and the hardness should be lower. The speed of the workpiece is high and the hardness should be higher. The hardness of dry grinding should be 1-2 smaller than that of wet grinding.

Binding agent:

The main purpose of the bonding agent is to consolidate the abrasive grains together so that they have a certain shape and strength to facilitate effective grinding work. There are three commonly used bonding agents, ceramic, resin and rubber.

Abrasive tools made of resin bond have high strength and elasticity, and are widely used in metal and non-metallic materials, high-speed grinding, rough grinding, forming grinding, super-finishing grinding, cutting, and grooving.

For concrete flooring industry, choose correct tooling are very important. People need to have an idea about when use Metal Diamonds, when choose Hybrid Transitional Polishing Pads, when use Edge Ceramic Polishing Wheels.
