What is CNC diamond cutting?

It is a precision machining process that removes a very fine layer from the alloy wheel face, recreating the bright lines associated with a diamond-cut factory finish.

Can every alloy wheel be diamond cut?

No. The wheel design, condition, previous machining and remaining material determine suitability. We inspect the wheel before confirming the service.

Can a diamond-cut wheel be repaired more than once?

Sometimes, but not indefinitely. Every cut removes material. A physical assessment is needed to decide whether another cut is appropriate.

Is diamond cutting the same as polishing?

No. Diamond cutting uses CNC equipment to machine the face and create fine concentric lines. Polishing uses a different surface-finishing process.

How do I request a quote?

Send clear photos of the full wheel face and each damaged area through WhatsApp, together with the vehicle make, model and number of wheels. Final suitability may require inspection.

What this service does

Diamond-cut wheels have a distinctive bright face with fine machining lines beneath a protective clear coat. Our CNC process removes a controlled amount of material from suitable wheel faces to refresh that appearance.

The wheel is assessed before any machining begins. Preparation removes the previous finish and addresses appropriate cosmetic damage. The wheel is then mounted on specialist CNC equipment, where the face profile is measured and a fine layer is precisely cut away. A compatible protective finish is applied as the final stage.

When it may be suitable

Cloudy, peeling or tired clear coat on suitable diamond-cut wheels
Light face corrosion and cosmetic marks that can be removed safely
Restoring a clean two-tone, factory-style wheel appearance
Refreshing individual wheels or a complete matching set

A diamond-cut wheel cannot be machined indefinitely. Previous cuts, damage and remaining material all affect suitability, so every wheel needs assessment first.

Why the assessment matters

CNC diamond cutting removes metal from the face. That makes accurate setup and a suitability check essential. Wheels with significant damage, too many previous cuts or unsuitable profiles may need a different refurbishment route.

Looking after a diamond-cut finish

Use a pH-neutral wheel cleaner, avoid harsh acids and do not hold a pressure-washer nozzle close to the wheel edge. Cleaning brake dust regularly helps protect the clear coat. Stone chips and kerb damage should be addressed before moisture spreads beneath the finish.

How it works

A specialist, controlled process.

The exact steps may change after the wheel is physically assessed.

STEP 01

Assess

Check wheel condition, previous machining and whether another safe cut is appropriate.

STEP 02

Prepare

Strip the old finish and prepare repairable surface damage for machining.

STEP 03

Machine

Map the wheel face and make a controlled precision cut on the CNC lathe.

STEP 04

Protect

Apply the specified finishing system and carry out a final appearance check.
