과제
"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.

자동차 prototype case notes for sourcing teams
자동차 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.
자동차 suppliers, engineering teams, mobility startups, aftermarket product teams, and industrial design groups.
