The Challenge
"For Brown Formula Racing, wheel hubs are mission-critical components integrating the drivetrain, bearings, and wheels. These parts withstand massive cornering forces and braking torques."
Critical Requirements
- Excellent concentricity to prevent vibration at high speeds.
- High-strength performance combined with aggressive lightweighting.
- Precise thread engagement for reliable wheel locknut safety.
Our Execution
As a premier provider for motorsports, we developed a comprehensive strategy combining lathe work and 5-axis milling.
Minimized Setup Strategy
We used a two-sided turning strategy. Each end was rough-turned, finish-turned, drilled, bored, and threaded with controlled flipping to maintain datums and ensure alignment.
Deep Pocket Machining
For challenging internal pockets, we used a multi-step approach: pilot drilling for chip clearance, helical rough milling, and controlled finishing passes.
Custom 5-Axis Fixtures
Dedicated fixtures were designed for secure clamping during 5-axis machining, eliminating cumulative positioning errors.
