El reto
"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.

Evidence basis
Ingenieria evidence record
Automotriz prototype machining record. This public case summary is based on anonymized RFQ notes, engineering review, inspection planning, and packing handoff records; customer-sensitive details removed.
Automotriz prototype case notes for sourcing teams
Automotriz prototype work needs practical communication around material, fit, finish, inspection, and timeline because a part may be used for assembly checks, design validation, display, or early vehicle testing.
CNC machining, 5-axis machining, sheet metal fabrication, surface finishing, and small-batch assembly support.
Mark critical dimensions, mating interfaces, finish surfaces, material grade, and whether the part is for visual review or functional test.
Before-shipment photos, key dimension reports, finish confirmation, packaging review, and revision notes for future batches.
Automotriz suppliers, engineering teams, mobility startups, aftermarket product teams, and industrial design groups.
Cómo preparar una RFQ lista para cotizar
Before quoting, send the part purpose, CAD revision, material target, finish, tolerance-critical features, inspection expectations, packaging needs, and destination so engineering can price the correct route.
Lo que ingeniería necesita para revisar con precisión
Una RFQ más sólida identifica el objetivo funciónal, las dimensiones críticas, los requisitos estéticos, la cantidad, las restricciones flexibles y la evidencia de inspección esperada antes del envío.
Phone-photo case evidence
Case pages need project-context proof, not only finished render-style images. This evidence shows drawing review and quote-stage engineering work before prototype production.
