| Surface Treatment | As‑machined; optional: hard anodizing, chromate conversion coating, shot blasting, powder coating |
| Tolerance Requirement | Follow drawing dimensional & geometric tolerances; concentricity ≤0.03 mm, position tolerance ≤0.025 mm |
| Target Industries | New‑Energy Vehicle Chassis, Performance Car Suspension, Commercial Vehicle Steering System, Racing Automotive Components |
| Production Scope | Prototype development｜Small‑batch trial｜Mass‑volume production |
| Feature | Our Manufacturing Capability |
|---|---|
| Complex Structure Machining | Adopt imported Hermle high‑end 5‑axis simultaneous machining centers. One‑setup completes 3D contour milling, multi‑angle surface machining, boring, drilling and tapping for irregular multi‑arm steering knuckle bracket. Avoid multi‑station transfer errors and repeated‑clamping deviation of standard 3‑axis CNC machines. |
| High‑Precision Control | Unified machining reference datum. Tightly controls central bore concentricity ≤0.03 mm and lug‑hole position tolerance ≤0.025 mm. Guarantees interchangeable assembly, reliable bearing fitting and chassis running stability. |
| Process Difficulty | 6061‑T6 aluminum alloy thin‑wall hollow multi‑arm structure is prone to cutting deformation. Complex irregular contours, distributed offset lug holes and multi‑directional mating surfaces. As a chassis safety part, strict burr‑free edge requirement; secondary clamping will introduce obvious position error which risks assembly failure. |
| Benefit of One‑Clamp Forming | Hermle 5‑axis full‑feature one‑clamp forming with zero repeated positioning offset. Stable batch‑to‑batch dimensional consistency, improves yield for complex lightweight automotive chassis structural parts. |
| Surface Quality | Precision finishing for bearing fitting and load‑bearing mating surfaces, full deburring for all edges. Suitable for high‑load chassis working environment of passenger cars and new‑energy vehicles. |
