This type of wheel undergoes a precision process where it is mounted on a lathe, and the paint from either a portion or the entire surface is removed, revealing the gleaming alloy beneath. A thin layer of the alloy itself is carefully machined away to achieve this polished effect. To protect against corrosion, the wheel is then coated with a clear lacquer.

You can identify a diamond-cut wheel by looking for the extremely fine lines that the cutting process leaves behind, giving the wheel a particularly bright finish. However, discerning this may be challenging if the wheels are of low quality, aged, or have suffered corrosion.

It’s important to note that not every wheel is suitable for diamond cutting, as the feasibility largely depends on the wheel’s face profile. A specialist from the Onyx Alloy team can provide guidance on whether this process is an option for your alloy wheel.

Wheels with a diamond cut finish may not maintain their appearance as effectively as those finished with powder coating. Even minor scratches or damages to the protective lacquer can allow moisture to infiltrate between the lacquer and the metal, resulting in unsightly “milky” blemishes on the diamond cut areas. For any questions or concerns regarding your wheel, it’s advisable to consult with your Onyx Alloy Wheel Specialist.

The repair process for diamond cut wheels typically involves 1 to 2 cuts, based on the specific needs of the repair. However, if there’s any concern that cutting the wheel might compromise its integrity or weaken it, our technicians will opt not to cut the wheel and will recommend a Powdercoat finish as the best refurbishment option instead. At our facility in Slough, every wheel is carefully evaluated on a case-by-case basis. We encourage you to let our technicians know if your wheel has undergone cutting previously.
