Le defi
"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.
Points techniques
- Tournage CNC (Rough & Finish)
- Deep Hole Drilling
- Precision Boring
- Dynamic Pocket Milling
- 5-Axis Contour Finishing
Automobile prototype case notes for sourcing teams
Automobile 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.
Automobile suppliers, engineering teams, mobility startups, aftermarket product teams, and industrial design groups.
Comment DFocus utilise cette page
Cette page fait partie de la preparation du devis. Elle transforme une idee de prototype en brief de fabrication avec procede, matiere, tolerances, finition, inspection et expedition, packaging notes, and delivery assumptions.
Ce qui renforce le RFQ
Un RFQ plus solide explique ce que la piece doit valider, quelles cotes comptent, si l apparence ou la fonction prime, la quantite, les points flexibles et les preuves attendues avant expedition.
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.
