Diamond Cut Alloy Wheel Refurbishment
Diamond Cut Alloy Wheel Refurbishment
Diamond cut wheels are known for their sharp, reflective finish – but they can be prone to corrosion, kerb damage, and lacquer failure. At Onyx Alloys, we specialise in diamond cut alloy wheel refurbishment, restoring your wheels to their original precision-machined brilliance using CNC lathe technology.
Our process involves stripping the old finish, repairing any surface damage, and then machining the face of the wheel to a smooth, polished shine using our in-house CNC lathe. This is followed by a protective lacquer to ensure a stunning result that lasts. The end result is a sharp, clean finish that perfectly matches the factory look or even improves on it.
We serve Slough and surrounding areas, offering fast turnaround, loan wheels if required, and meticulous quality control. Whether your wheels have lost their sparkle or you’re preparing a lease return, our diamond cut refurbishment gives your alloys the standout finish they deserve.

Yes, but only a limited number of times. Each cut removes a small layer of metal, so we inspect wheels before any repeat work.
Absolutely. Our CNC machine provides a factory-grade finish that restores the wheel’s original appearance and shine.
