Diamond-cut alloy wheels are one of the most premium wheel designs available today. Their sharp metallic finish and precision-cut lines give cars a luxury appearance. However, Mumbai’s road conditions—potholes, flyover joints, water-logged streets, and tight parking—often damage these wheels.
That’s why Diamond Cut Alloy Wheel Repair in Mumbai is a specialised service that requires advanced machinery, trained technicians, and a precise repair process. A normal paint job cannot restore a diamond-cut finish.
As a trusted alloy wheel shop in Mumbai, Wheels Repair Sales repairs diamond-cut alloys daily for both premium and regular vehicles. This guide explains exactly how experts repair diamond-cut alloy wheels step by step, what makes the process different, and why choosing the right workshop matters.
Why Diamond-Cut Alloy Wheels Get Damaged in Mumbai
Mumbai’s driving conditions are tough on wheels:
- Deep potholes hidden during monsoon
- Broken road patches and flyover joints
- High curbs and tight parking spaces
- Heat, humidity, and pollution
Diamond Cut Alloy Wheel Repair in Mumbai is necessary because the CNC-machined surface gets scratched, bent, or dull due to potholes and harsh road conditions.
Common problems include:
- Curb rash
- Loss of shine
- Peeling clear coat
- Bent rims
- Hairline cracks
What Makes Diamond-Cut Alloy Wheels Different?
Diamond-cut wheels are finished using CNC machining, where a thin layer of metal is shaved off to create a reflective surface.
Key differences:
- Two-tone finish (paint + metal cut)
- Mirror-like shine
- Very thin surface layer
- Cannot be restored by polishing alone
That’s why Diamond Cut Alloy Wheel Repair in Mumbai must be done using CNC machines—not manual methods.
Step-by-Step Process: Diamond Cut Alloy Wheel Repair in Mumbai
Professional workshops like Wheels Repair Sales follow a strict, safe, and proven repair process.
Step 1: Initial Inspection & Assessment
Technicians check:
- Scratches and curb rash
- Bent rim edges
- Cracks or air leaks
- Depth of damage
- Previous diamond-cut history
Digital gauges measure wheel run-out and thickness.
Step 2: Straightening the Wheel (If Bent)
If the wheel is bent:
- Controlled heat is applied
- Hydraulic pressure reshapes the rim
- Wheel is restored to factory roundness
This step ensures safety before cosmetic restoration.
Step 3: Crack Repair Using TIG Welding (If Required)
For cracked wheels:
- TIG welding is used
- Minimal heat prevents metal weakness
- Welded area is reshaped and tested
Only safe cracks are repaired. Severe damage may need replacement.
Step 4: Stripping Old Paint & Coating
Old paint, lacquer, and damaged layers are removed completely to prepare the wheel for refinishing.
This ensures:
- Proper adhesion
- Clean CNC cutting
- Long-lasting finish
Step 5: Base Painting or Powder Coating
A base colour is applied (usually black, grey, or silver).
This layer:
- Forms the background colour
- Enhances contrast after CNC cutting
- Adds corrosion protection
Powder coating is often preferred for durability.
Step 6: CNC Diamond Cutting (Most Critical Step)
This is the heart of Diamond Cut Alloy Wheel Repair in Mumbai.
Process:
- Wheel is mounted on CNC lathe
- A thin metal layer is shaved
- Precision lines recreate factory finish
- Exact depth control prevents weakening
Even a 0.1 mm mistake can ruin the wheel—experience matters.
Step 7: Clear Coat / Lacquer Application
A UV-resistant lacquer is applied to:
- Protect against moisture
- Prevent oxidation
- Maintain shine
- Withstand Mumbai’s humidity
High-quality clear coat is essential for long life.
Step 8: Oven Curing & Drying
The wheel is oven-cured to:
- Harden the coating
- Improve durability
- Ensure uniform finish
Step 9: Wheel Balancing & Final Safety Check
Final checks include:
- Wheel balancing
- Pressure testing
- Visual inspection
- Road-safety confirmation
This ensures vibration-free, safe driving.
