As with sensible warnings, diamond blades are not designed to grind or cut steel. There are other tools to do the job. Remember that diamonds are made from highly condensed arrays of carbon atoms. Also remember that steel uses carbon as a strengthening element. In fact, steel is an iron-carbon alloy that adds chromium and several other exotic metals to the mixture. Diamonds and steel do not mix together.
Complex microcrystalline structure
- Yes, steel has a complex grain structure. It is formed as an austenitic material, a martensitic alloy and a few super tough alloys.
- Unlike hard stones, glass and ceramic tiles, those closely packed grains are very hard and almost impossible to break.
- Needless to say, diamond blades can still polish or add finish to the steel, but the process is difficult to control, so seek other grinding solutions.
- The steel is also heat treated and filled with carbon toughness.
- Again, as mentioned above, diamonds are another form of carbon, albeit a more attractive and desirable form.
Wear-resistant friction constraint
When the diamond blades collides with the steel, a large amount of heat is released. The heat loosens the diamond bond and causes the synthetic crystal to scatter. The surface of the diamond blades is coated with nickel and will therefore corrode. Almost as if the steel surface would affect its own abrasive effect, the particles and diffused carbon would cut into the spinning diamond blades.
At the same time, the heat absorbs the diamond blades and the bond material decomposes more. Moreover, even when the friction effect does affect the expensive tool, heat also penetrates into the steel workpiece. Worryingly, as the temperature of the rotating diamond increases, the grains undergo a transition phase.
All signs point in the same way, so you should actually use an grinding wheel for steel instead of a diamond blades.
- Cutting disc can be used on fixed cutting machine, 3.0mm thickness, and it offers excellent durability which makes it suitable for most demanding clients.
- Cutting disc maximizes friction and sharpness, reducing the burrs after cutting.
- Cutting disc can be used on various cutting applications, increase side strength to ensure safer application.
- Has perfect abrasive performance and extra durability on application of steel.
- Large cut off wheels can be used in profile plates, debar and steel structures, especially iron and steels.
Diamond blades are expensive, among other things. Unlike cheap drills, we can’t just assume a free-spirited attitude and hope to get the best. This is a dual application method for steel, an intergranular hardening alloy that uses diffusion carbon.
When a diamond binder is used for such a hardened alloy, it wears quickly. The crystalline carbon layer does not react well with the steel-diffusing carbon, so a large amount of frictional heat can cause damage to the diamond cup grinding wheel and deformation of the workpiece grains.
Synthetic diamonds can even oxidize when overheated, and this heat is unavoidable.
Finally, steel alloying elements are soluble in carbon, so don’t think this is a viable option, not when there are more powerful steel grinding solutions on the market.
