Diamond grinding wheels are not typically recommended for grinding steel. While diamond is one of the hardest materials and is well-suited for grinding hard materials like concrete, stone, ceramics, and certain metals, it has limitations when it comes to steel.
Steel contains iron, and during the grinding process, the high temperatures generated can cause a chemical reaction between the carbon in the diamond and the iron in the steel. This reaction can lead to the formation of iron carbide, which is harder than the diamond itself. As a result, the diamond particles may wear down quickly, reducing the effectiveness of the grinding wheel and leading to premature wear.
For grinding steel, it’s more common to use abrasive grinding wheels made of materials like aluminum oxide or silicon carbide. You can also use the carbide boron nitride cutting wheels. But carbide boron nitride cutting discs are much more expensive then diamond cutting wheels. We can also offer you the brazing CBN cutting wheels especially used for steel.
Always refer to the manufacturer’s recommendations and guidelines for the specific type of grinding wheel to use based on the material you are working with to ensure safe and optimal performance.
