Although both tools are abrasives, diamond grinding disc and grinding discs use different materials. Indeed, both types of equipment use a fast-rotating disc, so that the abrasive strength can be provided as long as the surface of the rotating disc reaches its maximum speed. However, from a deeper perspective, the physical difference becomes apparent on the diamond grinding disc line. Unlike steel cores of diamond grinding disc and sintered bonded crystals, the mill relies on scratched metal oxides.
Different bonding structures
Diamond grinding disc
Let us reduce the power of the grinder and make it safe. By placing it under light, it is clear that the tool uses a different physical structure. The diamond cutting wheel for angle grinder is rough and made of a resin material that has been bonded to the metal disk. The abrasive particles are combined with the bonding material so that they are evenly distributed in the resin. Moreover, the resin is not necessarily the only adhesive used here, and is not used for a long time. There is vitrified clay that melts like glass. Special rubber and mesh layers can also find a mixture of them.
Silicon carbide abrasive
The biggest difference is the abrasive particles locked inside the bond pad. No diamond was found in a conventional diamond grinding disc. No, this is a mass of evenly dispersed alumina particles. The series has a wide range of gravel substitutes, of which zirconia alumina and ceramic alumina are among the best in steel alloy grinding materials. Silicon carbide is another member of the abrasive grinding family.
