Wheel Machining
As well as over 30 years’ experience in CNC machining complex precision parts, we also specialise in custom automotive parts, such as alloy wheel machining.
Our custom automotive components for cars and motorcycles include the following:
- Wheel spacers
- Mirror extensions
- Brake spacers
- Wheel machining
Using state-of-the-art CNC equipment, we produce high-precision alloy wheel modifications and bespoke accessories designed for superior accuracy and performance.
Custom Drilling for Blank Alloy Wheels
Custom CNC drilling for blank alloy wheels, accurately matching any PCD to your vehicle’s specifications. Ideal for aftermarket wheels, unique builds, or performance upgrades, our service guarantees a perfect fit.
Centre Bore Modifications
Our CNC centre bore modification ensures a precise, vibration-free fit for alloy wheels. By matching the centre bore to your vehicle’s hub, we provide custom fitment that improves alignment, safety, and performance.
PCD Re-Pitching
Our precise CNC PCD re-pitching adapts bolt patterns like 5/112 to 5/114, ensuring a secure custom fit for alloy and performance wheels. Maintain strength, safety, and reliability with our expert modification services.
Offset Adjustments for Alloy Wheels – Increased or Reduced
Our offset adjustment services for alloy wheels use precision machining to increase or reduce offset, achieving the perfect stance and fitment for your vehicle. Enhance performance and aesthetics without compromising safety or alignment.
Wheel Plugging for Alloy Wheels
Wheel plugging for alloy wheels involves filling existing bolt holes and re-drilling new bolt patterns (PCD) using precision CNC machining, ensuring a secure fit and maintaining wheel integrity.
Spigot Rings for Hubcentric fitment
Achieve a secure, vibration-free hub-centric fit with durable spigot rings, designed to improve wheel alignment and performance.
Hub-centric Wheel Spacers
Ensure a secure, vibration-free fit with our hub-centric spacers, ideal for improved alignment, handling, and vehicle stability.
Slip-On Wheel Spacers
Designed for minor offset adjustments, slip-on spacers enhance your vehicle’s stance and performance without compromising safety.
Bolt-On Wheel Spacers
Perfect for larger offset adjustments, bolt-on spacers provide a secure fit and an aggressive stance for performance and off-road vehicles.
Precision CNC Alloy Wheel Machining Services
Modern diamond-cut alloy wheels add a premium, sophisticated aesthetic to any vehicle. However, when these wheels suffer from kerb damage, corrosion, or distortion, traditional painting or hand-sanding methods cannot restore that distinct, precision-machined factory finish.
At TT Precision, we specialise in high-end CNC alloy wheel machining and diamond cut wheel repair. Utilising state-of-the-art, computer-controlled lathes and advanced digital profiling technology, we can skim fractions of a millimetre from the face of a damaged wheel, restoring its original geometry, sharp lines, and brilliant reflective finish to exact factory specifications.
The Diamond Cutting Process: Engineered Precision
Diamond cutting is a highly technical engineering process that requires absolute accuracy. We treat every alloy wheel with the same level of care and precision that we apply to our aerospace and industrial engineering components.
- Digital Laser Probing & Profiling: The wheel is securely mounted to our specialised CNC lathe. A high-precision digital laser scanner probes the exact curvature and unique geometry of the wheel, mapping out a custom 3D digital profile.
- Micro-Precision Skimming: Our engineering team configures the CNC software to remove the absolute minimum amount of material necessary to clear the kerb damage or corrosion. A specialised diamond-tipped cutting tool then skims a microscopic layer off the wheel’s face.
- Flawless Finish: This precise cutting action creates the iconic, pristine metal finish characterised by ultra-fine lines, which is then sealed with a premium, durable clear coat or lacquer for long-lasting protection against weather and road salt.
Why Choose TT Precision for Alloy Wheel Machining?
Unlike standard body shops or mobile repair vans that attempt to fix diamond-cut wheels using hand tools, our dedicated workshop approach guarantees structural safety and flawless finishes:
-
Microscopic Material Removal: Our advanced CNC lathes ensure we only cut away what is absolutely necessary. This preserves the maximum structural thickness and safety integrity of the alloy wheel, allowing for future refits if needed.
-
Elimination of Distortion: If a wheel has a slight lateral run-out or flat spot, our precision machining setup allows us to identify the variance immediately, ensuring the finished wheel spins perfectly true.
-
Bespoke Custom Machining: In addition to standard OEM restoration, we provide custom profiling for bespoke automotive builds, prototype wheels, and motorsport applications requiring custom centre-bore alterations or offset modifications.
-
Unrivalled Engineering Expertise: As precision engineers, our understanding of metallurgy, tolerances, and cutting-tool dynamics ensures a level of finish that standard refurbishment centres simply cannot match.
